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.

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.

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 :problem:

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.

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.

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.


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* :evil:

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...
