Club 3d MST Hub Issue

[oliverm3]

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.

[oliverm3]

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.

[suiken_2mieu]

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

[oliverm3]

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.

Thanks mate.

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.

[oliverm3]

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

[oliverm3]

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!

[oliverm3]

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.

[Defcoms]

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.

[oliverm3]

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.

[Defcoms]

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

[oliverm3]

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?

[Defcoms]

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