Widescreen Gaming Forum

Hey Guys,

I've been reading the forums for quite a while thanks for all of the great info and tools on the site.
Anyway I just received my Club3d MST hub last week to try to eliminate screen tearing with my 1dp 2dvi setup on my 3 LG 22EA63T-P monitors at 5760x1080 with a Powercolor Devil 13 7990.

No screen tearing at all anymore in windows but monitors just go black randomly and I have to switch resolution and switch back to reset them or reboot.
It doesn't happen that often but it's annoying when the center screen goes out in the middle of a game. The sides do go out as well so it's not just the center connection.
Anyone have any experience running the mst hubs?

The previous direct 1dp and 2dvi connection never lost monitor connections.

I am running some adapters as well the 3 displayports are adapted to dvi with passive adapters as well as a mini dp to dp for the connection to the machine.

I have to say it shipped super quick from Germany when I ordered from amazon I had it within a week. If you order them make sure you have a power source as well they come with a euro plug but the brick does accept a 3 prong plug from an old dell docking station I had

Thanks for any help!

Hehe, guess you're one of the first here to posses one!

Did you set your monitors to DVI input and not Auto?

Thanks that's a good idea I'll give that a shot when I get home.
I typically just leave them on auto and forget about them.

Oh well they were on DVI already not auto. I tried switching the mini dp port to the other one who knows maybe.
It takes a while or on reboot or sleep mode for me to lose one so I guess I need to play a lot to see the pattern.

Other than them going off no tearing even with vsync off.

I just ordered mine from Amazon. I am waiting for it to arrive its coming from Germany to US. Once I get it I will post my results. I will be using regular Displayport monitors though with no adapters. I was hopping this will fix the screen tearing I have when on the desktop and also allow the use of vsynch. I never could get vsynch work with eyefinity and trifire 7970's.

Do you have picts of the power cable? What exactly do I need to get to make sure this works in the US?

Here you go,
I used the power brick that came with the hub I just replaced the euro 3 prong cable from the brick to the wall.
The 3 prong cable I used is one like the one in the dell docking station cable ebay auction I have listed below.
Seems pretty standard I've seen that style on printers and various other devices.
Let me know if you need any more pics.

Still no word from Club3d with any suggestions to try.

I'm reluctant to start switching out adapters they're not exactly cheap.
I could try the hub on my sons eyefinity setup he still has lcd's.

That wont really help me though I'm not switching from my bezelless leds.
But it would pint point the problem.

Please keep us updated, being that these units are new on the market, any behaviour experience we can gain will be valuable.

The system appears to still see the display because I'm not losing my display group.
I guess I'll put the hub on my sons system for a few days and see if he still loses them with his LCD's

Well the problem followed the hub. My son let me know today that yesterday and today different screens went
black on him either booting the system or switching between games.

Our system specs are:
Mine
Windows 8 64bit.
Powercolor Devil 13 Radeon 7990 gen1
Intel 4770k and Asus Sybertooth x79
Running 3 LG 22EA63T-P 22" monitors.
AMD cat 13.6 beta

Sons System.
Windows 8 64bit.
AMD 8350
SABERTOOTH 990FX/GEN3 R2.0
MSI R7950 Twin Frozr 3GD5/OC Radeon HD 7950 3GB
Running 3x HannsG HL229DPB 22" monitors.
AMD cat 13.4

On the plus side it means there's nothing wrong with my awesome monitors.
I love these things I can't believe how much better they look than my lcd's

I've ordered 3 new adapters http://www.newegg.com/Product/Product.a ... 6882607005
We'll see if the old dell dp to dvi adapters I had laying around were the problem.
I've had good luck with accell products so maybe it's just the dell adapters causing problems.

Support has been in contact with me and suggested trying
1. Remove all old drivers.
2. Reboot and get in the OS
3. Shutdown
4. unplug all devices and cables.
5. Reboot
6. Plug in the devices.
7. Reboot
8. Install the drivers.
a. AMD cat 13.4
9. Reboot
10. Set up the hub.

I may attempt it when I have some time but that's typically what I do anyway when switching drivers.
Well with the exception of unplugging everything what does that do but boot your system with no monitors?

I'll keep you posted

I received my Club3D hub. The tearing issue I had is gone, but vsynch with crossfire/eyefinity is still a stuttering mess. I have not experienced any of my monitors dropping out but I am not using any adapters my screens have displayport input. everything works as it has minus no more tearing!

That's strange never had stuttering with crossfire except for games that have crap scaling like GW2 I leave crossfire off for that one.
I'm curious why vsync now that you have a hub? I wouldn't think you would need it.
I get about 120fps - 200fps in bf3 and no tearing with vsync off.

BTW new Accell DP++ to DVI adapters are in so we'll see how they run for the next couple days.
cross your fingers maybe it was just the crap dell dp to dvi adapters.

I normally don't use vsynch and my game play is smooth. I was just testing if the stuttering with vsynch was from mixed outputs and crossfinity.

Well that didn't work.

Lost monitors again with the new dp++ to dvi adapters.
I even swapped out the power cord that goes from the brick to the wall.

I'm not really sure what else could be causing this.
oh and also swapped out the mini dp to dp adapter that's connecting the hub to the card and tried the other dp port on the video card same problem.

I've e-mailed support again to see if they have any ideas.

I'll keep you posted.

I was just looking at the back of the box and there is a list of Club3D supported accessories. I would think that you would need to buy one of the supported accessories that the manufacturer has tested to work with their product. Buying one not on the list is going to be hit or miss.

I have had no issues with my hub everything is working perfect but I am using displayport monitors with no adapters.

Here are all the part number that are recommended by Club3D

Club 3D recommends:
CAC-1000 - DP to SL5 DVI-D
CAC-1001 - DP to HDMI
CAC-1002 - DP to VGA
CAC-1050 - DP to DL6 DVI
CAC-1051 - DP to DL6 DVi 3D
CAC-1052 - DP to SL5 DVI
CAC-1053 - DP to HDMI 3D

SL= Single Link
DL= Dual Link

I don't think that's it. Their CAC-1052 is just a generic Accell adapter.
Also I sent them the links to everything I'm using and they didn't say anything about them not being supported.
I'm really leaning toward a hub or driver issue.

Which driver are you using with the hub?

I'm using the new 13.10 driver since yesterday but I was using 13.8b2 since I had the hub.

Defcoms are you using a mini dp to dp adapter for the connection to your computer?

I guess we'll see I did the:
1. Remove all old drivers.
2. Reboot and get in the OS
3. Shutdown
4. unplug all devices and cables.
5. Reboot
6. Plug in the devices.
7. Reboot
8. Install the drivers.
a. AMD cat 13.10
9. Reboot
10. Set up the hub.

As suggested by support.
13.10 lost a monitor during the setup right after the driver was finished installing.
Adding it to a display group turned it back on but I'm not to confident that the driver resolved any issues.

Maybe the hub has a problem using adapters of any kind or that I have them on both ends.
I'll try the club 3d mini dp to dp adapter next. I'm using the one that came with my Devil 13.
Since it came with a 1k card I would expect it to be a quality adapter but who knows.

I'll keep you posted.

I don't know what else to try sounds like you have covered everything I would have done. You using windows 7?

Windows 8

Ordered the Club 3d mini dp to dp adapter from Germany guess we'll see in 11-30 days if that's the problem.
I did notice today that plugging and unplugging the mini dp connection for the driver install steps I must not have had it seated all the way and only one of the 3 monitors turned on.

I'm hoping that maybe that adaptor is the problem.
At this point I'm just on a mission to solve the problem I could go back at any point to not using the hub since I only had screen tearing when sliding windows around in windows 8 never in games.

Hi all! I'm having the same issue with random monitors blinking off using the Club3D displayport mst hub. I'm a design engineer and work alot in Solidworks and other engineering programs while also watching movies, working in Office, and generally multi-tasking my butt off so my system is probably a bit different than what most of you are running. Apparently I am way ahead of other pro-side users and can't seem to find much in this topic except on gaming forums so maybe by posting my issues in here we can figure out a solution. I just got it all running this evening and am having issue (randomly both time between blinks and which display) with 1 display at a time going black for a few seconds and then coming back on by itself. OK, so a bit about my setup:

HP Z800 Workstation
Dual Xeon Hexcore E5645's
48GB Mushkin Silverline Memory
Intel 520 Series 240GB SSD (OS & Programs)
Seagate ST1000DM003 1TB for storage
AMD Firepro V5900 (Just cleaned and fresh-installed Catalyst Pro V12.104)

2- ASUS VS247 (HDMI) passive DP adapter
1- Acer H233H (HDMI) passive DP adapter
1- Club3D DP MST Hub (aslo bought from amazon from link on this thread, took about 2 weeks,
had to swap power cable for US 110V style)

I'm running all 3 HDMI passive adapters off the mst hub and the hub is plugged into the DP on the card. second DP and DVI port on the card are unused at his time. In addition to the monitor blinking I am also seeing quite a bit of multi-colored pixel storming (just learned what to call it) on all 3 monitors, especially noticable on dark backrounds but I've read this could be due to older cheap-o HDMI cables. Maybe by seeing the same issue on a workstation card using the Catalyst Pro Software, someone will be able to figure this out and get it solved. I'm sure there are lots of you out there who would love to see this fixed before dropping the money on one of these hard to get hubs.

Willy

Hey Willy,

I've been working with Club 3d support. They are working on a new firmware for me to try on my hub. I should have it in a couple days.
I'll post the results and firmware here once I have it.

I'll let them know that you're having this issue as well.

I looks to me like it's pointing to a hub issues with this range of hardware.
My Sons AMD my Intel and your Workstation.

Willy are you running Windows 8?

I think defcoms said he is running 7 and he's not having the issue.

Yeah I am not having any issues with my hub at all. I am not running any active or passive adapters though. The only adapter I use is to connect the hub to my GPU, it's a mini DP to DP adapter that came with my MSI reference 7970's. All 3 of my monitors are the same spec wise. 2x Asus ve278q, 1x Asus vk278q the center screen just has a web camera but all 3 are native Displayport monitors. I do have a active dvi adapter I could hook up to on of my screens to test with and see if that screen drops out.

Oliverm3, Thanks for the assist! I did forget to mention I'm running Win 7 Pro x64.

As a trouble shooting update, I unplugged one of my monitors (the ASUS in case it matters) and plugged it directly into the 2nd DP on the card (by way of the passive DP-HDMI adapter). That monitor now does NOT blink off, only the two running throught the MST Hub now. i consider that a step in the same direction you are leaning that it's an issue with some aspect of the hub and I for one would love to see a firmware update make it go away. The fact that Defcoms is running Win 7 without any DP adapters downstream of the hub supports this as well.

I was going to test out my DP-DVI and DP-VGA adapters but I see that you are using DVI and I'm on HDMI so that probably isn't the issue. Instead, while we wait for that firmware update, I will try switching to running my identical monitors off the Hub and the odd man out through the card directly and see if it is possibly an issue with adapters and different monitors. Every little variable elimination should help them figure this out Thanks again guys!

I am wondering how they would update the firmware.

I guess they take them apart for the firmware because I just heard back. They want me to return the hub and they'll send me a new one with the updated firmware. Hopefully they ship one out first before I have to return this one.

I guess I could run without for a bit but the screen tearing annoys me.

I guess we'll have a wait a couple weeks for the next status update. I'm sure that it's going to take a while for me to get my new hub from the Netherlands.

I'll keep you posted.

Thanks for the update, do you have contact info for them that I could use to get the ball rolling on my hardware issue or are they wanting to see if it works before they claim it as a fix?

Yeah you might as well get the ball rolling it'll take some time shipping back and fourth to the Netherlands

I have been e-mailing them at [email protected]
I tried the online support form on their page but never received a response.

Wow I'm impressed they shipped it two day from the Netherlands.
So we should have an answer by this weekend because it's scheduled to be delivered on Friday.

Tested it again today and it's still repeatable 2 out of 10 reboots lost one monitor.
It is strange that two never go out only one and not always the same one.

I'm impressed with their response time as well! I emailed them and within about an hour they responded. The said they were sending you an updated hub and if it fixes the issue then they would take care of me too. They really seem to want to have a happy customer base. Oliverm3, thanks for the updates and hopefully we'll have good news by the weekend

So far so good 50 reboots and in and out of various games with no issue.
Its looking good since it would drop a monitor 2 out of 10 consecutive reboots.

I'll continue to aggressively test over the weekend and post the result but I think they may have solved the issue with the firmware update.
Total cost for the hub trying adapters and shipping back to the Netherlands $320. Don't tell my wife
I guess I took one for the team

Day two with the new hub no problems.

To bad the hub doesn't indicate which firmware it's using to distinguish a potential problem hub.
That way people don't drive themselves nuts trying adapters or drivers when the problem is related to the device.

So far so good though played a couple hours of games today and did about 40 reboots just to see if one would drop out.
And it has been problem free not a single monitor drop.

Thanks for the updates, they're encouraging. Hopefully after you've passed it along to club3d they will contact me so I can be as happy as you are it's too bad it's not user-updateable firmware.

Crap, Turned the system back on today after breakfast and lost the middle monitor.
Rebooted and it came back and has stayed on but I was hoping that I would not see that again.

3 days since the last one and I lost the middle monitor when going in to Saints Row IV last night. Had to alt+F4 and start the game again since I couldn't see the menus.

Not sure where to go from here.
I hope WLD13 has better luck.

I haven't been aggressively testing so the 3 days was just normal computer use a couple hours a day. I may sit down and do a reboot count to see how often they're going out now with this new firmware.

Waiting on my hub to show up, UPS shows it should be today so I will update this weekend with my results.

Oliverm3, sorry to hear your problem isn't completely gone. Out of curiosity, does your hub get warm? Do you have a mess of cables (like I do) behind the computer case around the hub? Not that I think that would be an issue exactly, just wondering.

I haven't really checked if the hub gets hot. I'll see tonight.
I have a good amount of room around the computer since I keep it on the outside of my desk in the open.

Between the 7990 Devil 13 video card and my overclock intel 4770k it kicks of so much heat I don't want the computer anywhere near me

I have lost the monitor on first boot though in the morning so I'm sure it was pretty cool at that point.

I don't believe it's a problem with mDP -> DP. The signal doesn't change and it would likely affect all monitors at a time.

I'd be more inclined to look at the DP -> DVI conversion. AFAIK it goes from a passive signal to an active (timed) signal. For that same reason that nearly all GPUs would only support any combination of up to 2 DVI/HDMI mixes. HDMI = DVI + sound/network, at least signal wise.

I don't suppose either of you is in a position to test the hub with DP connections to 3 monitors?

I believe Defcoms is using the hub with DP monitors and isn't having a problem. If I had three DP monitors I would just use them but the point is the beauty of DP MST hubs is that they are a solution to the only 2 clock signals per video card limitation. The hub actually provides the timing for the devices connected to it instead of the card so you can run 3 monitors of any type from each DP on the card and it it doesn't use up a clock signal. Currently with my configuration the video card is outputing NO clock signal as it onlys sees a DP connection which doens't require one. Also I tested the hub with only one monitor plugged into it and no other connections to the card and it wtill has the blacking out issue. When I use the other port on the card to run a monitor with a passive hdmi adapter that monitor functions perfectly, only the monitor connected to the hub has problems.

P.S. Oliverman3, it seems I am still having the same issues as before. It slowed down a bit at first but now I am back to the same frequency as before I swapped hubs. I am in contact with Club 3D and working it from my end. how are you faring?

Still the same for me It has slowed down but it's still happening from time to time.
I also tried one connection with the hub and the other two with mini dvi and dvi still lost the monitor connected to the hub.
also my hub only gets a little warm 92ºf not very hot at all.

I don't have dp monitors to test but really this product should support dp to dvi or it's pretty much useless.
Not many brands offer display ports.

And love my bezel-less LG LED IPS monitors I wouldn't want to have to switch monitors due to the hub.

Frist let me say to Oliverman3, WOW I like those monitors, what model are they? And yes I agree with you that these hubs are supposed to allow us to use whatever monitorNow on to the good (bad) stuff...

"Thanks for your mail and sorry to hear about the problems you still got.
When we send the hub to you we extensively test it with our Samsung and Dell monitors, it worked with no problem here, plug and play we did 10 reboots.
So we do not think the issue is with the hub.
What we did not check is what passive cables you are using, can you let us know about that first?
Another issue can be the monitors, did you speak with Asus if your monitors are compatible with the MST hub?"

Now I'm going to get the numbers off my adapters to send them but I don't remeber reading anything anywhere about monitors needing to be compatible with MST hubs. I'm also going to ask them if these monitors are DP monitors that they are using the HDMI or DVI connection on. I don't think a "dumb" monitor cares where the signal it is getting comes from, just that is is the correct format for the cable connection. It sure seems to me the signal interupt would have to be an issue with the device CREATING that signal. It may just be me but wouldn't it would be a little hard for manufacturers to have current monitors tested since these are the first adapters to hit the market and have only been out a few months.

On the troubleshooting side, the new hub they sent has actually started blanking 2 monitors at a time now, occasionally. Again, I have NO monitor drop when rebooting, just while using them. Any new troubleshooting data from anyone out there?

They're LG 22EA63T-P they make a larger one as well.
Let me just say even though they don't have a bezel they do have like a 1/4" black area around the screen it doesn't completely display to the edge but it's the closest I could find.

I've tested mine with the LG monitors above and my sons Hans-G monitors and APOC monitors all with the same problem.
I've also used DELL DP++ DP to DVI adapters and ACCELL DP++ to DVI adapters on the hub to monitor side.
On the mini dp to dp side I'm using a Club-3d adapter that I ordered from them.

I'm sure most monitors don't say specifically that they support mst hubs since there's only one out at the moment

I'm still losing monitors here and there going in and out of games.
No real input from support. Maybe they'll eventually figure it out but for now if you do not have display port monitors I would stay away from this product unless you can deal with losing monitors here and there.
A quick switch of resolution then back to your original will reset the lost monitor but it's annoying.

A cool test would be WSGF sending one around to people here and seeing just how many have failures on the various systems.
Then document all of the hardware configurations.

I'd hate to see a kid save for buggy hardware just to waste $160 on something that does not work as it should.
I've spent well over $400 on the hub and replacing adapters that ship from Europe.

I'd donate to see the results and help others.

So this only happens with adapters ? active or passive adapters non the less?

The problem with your idea would be that 1. WSGF does not have a MST hub. and 2. Shipping this thing around the globe would be around 10-30$ per time. so after shipping 5 times you would have the original price.
Way to expensive.
WSGF members are all around the Globe.

We gonna send it to outa space!

That's how it seems but the pool of people using it here is pretty small to really say.
1 out of 3 people have no issues and that one person just happens to have DP monitors while the other two have adapters.

Yeah I know probably to expensive to work unless club 3d can send test one and someone has a pool of friends close by with eyefinity setups.
or volunteers in neighboring states pass it to the next state/person. Maybe there's enough members right in the Netherlands to do some testing?
It's strange that Club-3d doesn't see this issue in their testing.

I bet 90% of people don't have DP monitors and if the hub doesn't work with adapters it's pretty much useless.
Maybe I can work out a deal with club-3d and try one more set of adapters that I get from them.

They should have the hub I returned Monday or Tuesday so maybe that will help them.

Well WLD13 I'm not sure if support has told you that they think the problem may be caused by the settings on the hub never getting reset since it's always on power You may want to try putting the hub on your surge protector and powering it off when you shut down your computer or after you reboot.

I don't really think that's the issue for me though since I do have the hub on my computers surge protector and I do power everything down when I shut my computer down.
I'm lazy I don't feel like powering on and off 3 monitors so my monitors the hub and the computer are all on one surge protector.

Next time I lose one I'll try power cycling the hub and see what that does.

Well this work around seems to be working:
Kind of cheesy that I have to power cycle the hub any time the machine is rebooted.
The Christmas tree foot pedal makes it quick though.

I'm really curious to hear if it had any affect with WLD13 since he was having more losses then I have. So far I have not lost a monitor in 3 days when manually power cycling the hub any time I reboot.

[little off topic] BTW, i irregularly have "screen drops" / black screen on dp monitor for 1 to 2 seconds on my 6970 eyefinity setup with 2x mini dp to dp monitors + 1 dvi... without any mst hub

Hi forum, I just bought a mst Hub recently and i have been experiancing simular issues, I use 3 Dell u2311h with native DP connections, could only get 2 monitors to run 1080p, the 3rd only ran 640x480 res. I get lots of Link failure messages. Screen blacking out, sometimes för seconds, sometimes permanent. Sometimes I cant even detect the 3rd display in catalyst. I've tried Dp cables, dvi cables with xfx active Dp adapters. I even bought 3 New monitors with Dp1.2 connectors. And the experiance was even worse. Sometimes there Will be no picture at all when I try to reboot. The New displays are u2412m. Used different drivers both catalyst 13.9 and .11 beta. I currently use 2x R9280X.
I hope there is a solution to this. Might be the driver or a faulty Hub. This has turned to a expensive nightmare.

That's pretty bad blacksight they do seem very inconsistent my last one was a lot worse then the new one they sent me with no change to my hardware. I'm currently running ATI Catalyst™ 13.11 Beta 6 with windows 8.1
Can you run all 3 monitors off the card without the hub? Just curious if you're having problems with out the hub.
Mine are solid without the hub I just get screen tearing in windows.

If you can't exchange it where you purchased it I would e-mail [email protected] they were pretty good about sending out us new hubs.

Could be a issue with the R9's I don't know anyone running them who knows how they like mst hubs.
Either way I would e-mail club-3d

Well, crap, I wish I had seen this earlier. I just ordered an Accell MST Hub (http://www.accellcables.com/K088B-002B.html) which I believe is identical in hardware to the Club3D MST Hub and am planning to run it against - guess what - 3 Dell u2311h monitors with native DP connections. We'll see what happens but I am a little worried since I am running 2 crossfired Sapphire Vapor-X 7970 Ghz edition cards which hardware-wise also are near identical to your R9 280X.

From other peoples experiences I think you should be good schreinereiner they seem to work better when using native display port monitors.
Thanks for the link to the accell one I may have to try that one out as well since this seems to be a firmware issue.
Maybe Accell did it right unlike the club3d version. My second club3d hub is a lot better then the first one that I was using.

It is still an annoyance and I had to adjust the way I use my computer so that every time I reboot the hub gets powered off.

Or "Mickey Mouse"



I remember people having similar issues with the DL Active DP adapters. They'd have to power cycle them (unplug and replug the USB power) to get the device to work. Delphium came along at one point and figured out that is was an amperage issue, and that if you plugged the adapter into an iPad power adapter (which is something like 1A), it woudl work fine.

Is everyone who's experiencing the issue turning their computer off at night? I just let mine go to sleep. Also, AMD has put me in touch with Club3D, and I will be getting a hub for testing.

There could be a few things going on here. First if your using an MiniDP > DP adapter, make sure it’s a DP 1.2. There are connectors out there that are not actually 1.2, and if it does not stat what type of DP it is it’s usually not a 1.2.
In both models it says that a HBR (High Bit Rate - 1.1 or lower) is only good up to 2 monitors at 1920x1080, and 3 if at 1600x900, if running 2560x1440 only good for 1 monitor
Whereas a HBR2 (DP 1.2) at 1920x1080 can run up to 4 monitors, at 1600x900 6 monitors, and 2560x1440 good for 2

I suggest doing 2 things, seeing if your connector to the hub weather it’s just an extension cable or a MiniDP > DP is actually a 1.2 cable. Also to drop your resolution too 1600x900 and run like that for a while.

I have been looking into these last few days before seeing this topic. It is good that I have so far not went with it, and like to know if above is a solution or not. The Monitors themselves should not be the problem at all, unless they were the MST chain ones, as this is supposed to be the solution to that at the moment. So it has to be the be either the cable to the hub or the hub itself.

Will report back once I have mine as well which should be mid-week. Cabling should not be an issue. Will be running the Accell hub without adapter straight from a full size 1.2 DP port on my card (http://www.sapphiretech.com/presentatio ... 1679&lid=1) to the hub and from there to 3 x 1.2 compliant cables (http://www.monoprice.com/Product?c_id=1 ... 1&format=2) and 3x Dell u2311h monitors. My main variable are the u2311h monitors since they only have 1.1a compliant DP inputs which "shouldn't" be an issue.

Sounds good. But yes, from the hub to the monitors should not matter the HBR rate from there. As to the hub its sending 3 screens of data in one shot, but from there it’s splitting it to 3 individual data streams. Un-like the MST daisy Chain that’s sending 3 screens of data to first monitor, then from there sending 2 screens of data to second monitor then, down to 1 for third. So everything there almost needs a high HBR such as DP 1.2 does.

DP 1.0 - 1.1 "maximum bitrate of 8.63 Gbps (gigabits per second)"
DP 1.2 "maximum bitrate of 21.6 Gbps"
HDMI 1.4a "maximum transfer bitrate is 10.2 Gbps " but this # seems to be a variable depending on Resolutions and weather is I or P as well. Also usually the combined number of Red, Green and blue channels, there seems to be no info if the other connectors fall into this as well.
DVI-I or D be it a single or double link model can vary from 1.65 - 2 Gbps roughly

I'm afraid my test run with the Accell hub will have no happy ending and I will be returning my unit.

While it resolved tearing completely I am now also dealing with monitors going into power save ALL THE F@#$%!NG time. I've played around with power settings both on the pc and monitor, different DP cabling, and monitor settings without success. It's not entirely predictable and just switching between Catalyst presets usually leaves me with blank monitors that need to be powercycled. Sometimes that doesn't help either. I've had occurrences where on boot none of the monitors powered on. Once I get them to stay on I do get non-tearing eyefinity on my three monitors but the erratic behavior of my monitors going into power save mode just isn't worth it. *sigh*

All these monitors going black and other such modes might just be a basic problem. It could all be from the power source itself, with so many things plugged in to 1 outlet or even a room at a time could drain it to a point some things start failing, or just protecting itself as a built in measure. As you increase the load of power drain be it from anything that ramps up the power consumption, just be even surfing the web.
You will have to try something else by running the power from that MST to another room or possibly other end of house. Most rooms even several, will be running from one source, that’s outlets and possibly Lights, depending on the Elect that wired the place. I am a Carpenter by Trade and seen a lot Different ways each Elect like to wire, I also build and rebuild a lot of computers, got 20+ years of parts in basement . But one thing almost all of them like to do is, since most bedrooms are in one area and usually never running much of a load, be it 1-4 rooms all plugs will be on 1 circuit, dens, living rooms, kitchens and such rooms almost always on their own circuit, so best run from one of them.
I have even had slight monitor shuttering due to this just before the computer locks up, and/or CTD's to compensate for power loss. Allot of the newer Surge arresters the last several years, even have dedicated plugs marked for certain things, reasons for this is if power starts to drop, it starts dropping connections itself protecting such things as the main PC as well. We use to see this a lot when we upgraded to newer Graphics cards but not upping the power supply as well, and in doing so we start a game and seemed like we lagging or we just always CTD, that’s the mother board reacting to the low power as well.

Hope this helps and works as its last idea I got for what’s happening.
PS sorry for long explained post, just like detailing reasons behind something’s, and possibly giving insight that may help for other reasons

Hi all,

Long time reader, first time poster. I bought a Club 3D MST hub a couple of months ago to use with my Matrix Platinum. Prior to this, I was running 2xdvi 1xDP with active adapter to my three Asus VN248H screens, I was getting the usual screen tearing and noted that the temps on my card at idle were about 10 degrees higher than running a single screen on the card (3 screens idle at 42c, 1 screen idle at 31c). The VN248H's only have HDMI and VGA inputs (I bought them for the bezel). I also noted that when running the screen through the DP adapter that particular screen would not come out of sleep on it's own and I'd have to reselect the input on the monitor itself to fire it back up. This did not happen when it was connected via DVI with a passive HDMI connection.

I got the hub mainly for the screen tear. To be honest I've been nothing but impressed with the hub since I bought it, whilst it does have a couple of issues I feel it does a very good job over using the bulk of inputs at the back of the card. One of the greatest benefits I've found was the reduction in temps on the card when using the hub, I'm assuming that as the card when it has three inputs in use is converting signals on board (as mine are HDMI monitors, it is actively converting the DVI signals?) the onboard "chippery" is working hard to both "do the graphics" as it were but also to push this out to three monitors that aren't native DP (this is my assumption, please don't shoot me down in flames if my understanding is incorrect!). Now with the hub installed, one DP connection into the card and three passive DP to HDMI cables from the hub to the monitors and all is well and with 10 degree lower temps at idle and load. Sweet!

However, all three screens now need to be power/input cycled whenever the machine goes to sleep or reset. Slightly annoying but isn't a deal breaker. I have had the issue when one of the screens goes blank but usually an alt tab out of whatever I'm in (usually BF4) to desktop and it will fix. The worst I've had to do was pull the offending monitor from the hub and put it back in and it worked again. I do feel though, all in all, for the £90 I paid the hub was well worth it for my setup (i.e. 3 HDMI monitors) and has removed screen tear and excessive heat which was my main concerns.

So, whilst it's not perfect, I certainly feel the hub is a worthwhile investment, especially if you're running non-native DP monitors. I actually thought the power/input cycling was more a problem with my monitors than anything else, I've certainly seen people complain about this away from the hub so that might be worth investigating first? Just my 2 cents...

All the best,

Sarge

Hi all

Just wanted to give some input from my experience with the club 3d mst hub. I recently upgraded my computer from a I7 2600k with 2 powercolors watercooled 6990, which had 4 mDp and a DVI outputs with the Apple active mDp to DVI-D dual link for 120hz. I am running WSGF 5P Benq XL2410t (120hz) monitor setup.

So for my new setup I kept my displays and went for a 4770k with trifire 290x but with only 4 outputs I knew the only way to get 5P was with a mst hub ( XL2410t only had DVI and HDMI inputs).

So to make a long story short I installed my windows 8.1 but the mst hub reported only 1 screen instead of 2 and the problem was it the resolution 3840( 1920x2)x1080 which is nice for landscape mode but not for portrait and I had the same lost signal crap as mentioned before in this thread.

Because I cut my monitors down I can't to landscape because the monitors no longer have any frame round it...

So I decided to try my windows 7 version instead. 8.40 minutes later windows 7 installed, in with AMD catalyst 13.12 restart and tada I had 5 individual monitors all running 1080p 60hz hit create eyefinity 5p mode and for the first time it really worked!

5400x1080 60hz no screen tearing what so ever No Frame latency to what so ever. Compared with my previous 5p 120hz this 60hz is much better experience it really feels like 1 monitor. AMD finally got it together and it's an awesome "product".

So club 3d mst hub is working like a charm at least for now.

Hope this helps people.

Happy new year!

Hi,

May i ask why you can't do 120hz ? HDMI won't support 120hz.... is thats it ?
MST DP hub should work for 2 screens 1080@120hz right ? and then you still have 2x DL-DVI ports.
The problem is the HDMI port right ?

Hi

Well from what I read and your free to change my mind the HDMI 1.4b standard makes 1920x1080 120Hz possible.

My problem with the HDMI seems to be my monitor XL2410T which is spec. for 120Hz but I believe only on the Dual DVI input, so there is one problem. But the only specification I find on the R9 290X HDMI output is that its 1.4a and support 2.0. Which obviously says nothing, but the HDMI out might/should be able to deliver 120Hz 1080P.

Second "problem" is that the mst hub should do like you wrote 120Hz 1080P 24b color on 2 outputs but again my dear monitors dont have DP input so Iam currently running 290x->MST hub->DP to Dual DVI cable (which is passive) so I can only get 60Hz there.

2 Dual DVI outputs are ofc capable of running 120Hz.

So what I need (I think) is

1: 2 DP to Dual DVI active adaptors for the mst hub outputs, I havnt found any yet that are 100% sure to work,
2: 1 HDMI to Dual DVI active adapter. (If the 290x HDMI is able to deliver it).

So you/anyone got a good tip of these 2 adapters that really WORK, that apple minidp to dual dvi worked but it was a heek of a effort to get all to work simultaniously.

But there you have it, advice is very welcome on how to go forward from here, though I soon gone tear my gear appart to install water cooling on all the cpu, motherbord and gpus.

Ps

And now I switch from 290x hdmi to hdmi, 290x hdmi to dvi and oboy did the picture quality improve.

I used one of these with my Retina MBP and my 21:9 2560x1080 monitor. It's mini-DP, but it's much cheaper than the Apple version (or any other version I've seen).

Ah okej thanks for the tip. But I sold my 2 6990 for 3 290x, and they don't have mini dp. Only 2 dp 1hdmi... And 2 dvi. So what I am looking for is a hdmi to dvi 120hz adapter and dp to dvi 120hz.

Alright, sorry to Necro thread, but I'm having the same sort of issue with this hub. Fixes screen tearing on my 3 DP monitors but get the blanking screen effect on all three monitors, one at a time and seemingly randomly.

So same sort of issue even when running with displayport cables and no other adapters besides the Club 3d MST hub!

I'm not sure what to do to fix this, might be better just to live with screen tearing and go back to 1x DP 2x DVI....

Anyone can check triple monitor configuration with INTEL haswell IGP on displayport??

I have H81TN mobo + G3220 cpu + club3d mst hub

main monitor i plug to hdmi port on motherboard + mst hub on dp (in mst i use two dp outputs bcoz i have only dp/dvi adapters for now)
DP @ DVI ACTIVE and DP @ VGA ACTIVE

when i plug dp hub to dp port i get info (intel dp topology or something) and see two displays
In prosperities i see only one (one main and one from dp hub)

but overall i get all black screens (except main which is plugged to native hdmi port on mobo)

I have two brand new mst hubs and on both the same situation

Greetings, Here I will explain my problem with the Club 3d MST Hub (CSV-5300).

I have a modest PC but pretty well optimized and functional, I like the multimonitor option and I have gradually grown from two to three and now five monitors.

My setup is:
ASRock 870 Extreme3
AMD Phenom II X4 955 Processor
2 ASUS Radeon HD 7770 (HD7770-DC-1GD5-V2) (Crossfire)
2 ASUS R9 290 (R9290-4GD5) (Crossfire) (NEW)
Kingston HyperX Grey DDR3 1600 PC3-12800 16GB (4x4GB) CL9

The point is to have an Eyefinity environment, five monitors must be able to connect to the same graphics card. For this reason I have acquired the Hud MST.

After the basic installation, configuration screens in the system seems to work well. Detects and monitors allows the creation of the desktop.

The problem is that none of the three monitors working. All displayed in black. Every 10 or 20 minutes, the image appears a few seconds.

Monitors are:
1 DELL E1909WDD (Displayport)
2 BENQ GL951A (VGA to Displayport)

The resolution of monitors is 1440x900/60Hz and in Portrait mode (5x1p).
Would I like to know what the problem is, you need special monitors?
Does not support 16:10 monitors?
Now my logic fails to understand what the problem is.

I need help, thanks...
