Big Problems with Nvidia GTX 285 1GB Card & MATROX TH2GO

[Les Parson]

I just received a new custom built Vista-64 rig; i7 940 OC, with 6GB RAM and the NVIDIA GTX 285. After using the MATROX TH2GO for a couple of years, this is definite requirement. While the system was enroute and much to my horror, I learned there are compatibility issues between MATROX TH2GO and GTX 285. Basically, one is not able to come close to the expected resolution; I can't even fill the three monitors !

If there is some sort of work around, I will be very, very grateful if someone could share?

PS - I have three VGA only monitors with a TH2GO Digital Edition.

Thank you again,

Les Parson

VGA only??? Do you mean analog? Have you gone the the TH2Go forums? Or maybe you can run with an older driver for the card?

I run analog monitors with a TH2Go (analog) on a 8800GTX without any problems.

I'm not having a problem with mine. Using it on all four OS's... Mike

Ok, thanks. Sometimes I get at least 3840 x 1024 with three analog monitors; other times (like now) the image won't stretch across the three 19" monitors.

Below is the best information I've been able to locate on the topic:

"Just got off the phone (http://www.nvnews.net/vbulletin/showthread.php?p=1984331#) with Matrox support.

Turns out the GTX285 and 295 have a "known issue"


the driver locks the pixel clock at high resoutions forcing a refresh rate of 48hz


Turns out you were right.

They're working on a fix now, with Nvidia.

Basically the "fix" is nvidia needs to unlock that speed... shouldn't be too difficult just bureaucratic BS."

This is quite a bit over my head; I'm just looking for a fix to this mess.

Thank you for your patience.

Is your head to go digital and your monitors are all analog?

[Les Parson]

Yes however, it has worked just fine in the past and even a couple of times with the new set-up; but not consistently. The resolution has'nt been as advertised, but was enough to fill the three screens. Now it won't even do that. I do hope I won't have to throw in the towel on this. We just got back from Bestbuy and I was looking at widescreens thinking if forced as an alterntative. I really prefer the TH2GO.

Why not pull the vid card from your old computer and test it in your new DS rig...If it works then tell DS that they have to offer you a different Vid card that will work..

Trust me..I sent 2 of their rigs back for reasons like this...

BUT...Its a good test..Hopefully you did not get GPU water cooling ...

[harleyman]

So Les...Have you tested with an older vid card to see if its working correct?

[Les Parson]

I attempted to do that however the existing GTX 285 had motherboard attachements that were daunting to me, so I decided not to remove it.

I even took today off so I could talk to a DS technical rep.

[harleyman]

That attachment is just a tab at the back of the PCI-E slot th locks the card in place..

All you do is after removing the two back screws(thumb screws) you pull the tab out releasing the card from the PCI-E slot...It bends out parellel with the mobo....

Look at the blut PCI-E slot..See the lock at the end..That is what releases the card

[Les Parson]

These are like electrodes attached to the card itself; definitely not made to secure the card. I meant to call DS today about it, but did'nt get around to it. I'm going on business trip tomorrow morning till Thursday; guess I'll have to wait till then.

[harleyman]

Hmmm...That card should have a 8 pin and 6 pin power connectoir to it...Is that what you're refering to?

Never heard of some sort of electrode thing there
