Hi,

This forum is amazing, it gave me many solutions for 16:10 gaming!! THX

But now, I have another pb...

I own the th2goD and since the beginning I cannot go higher than 800*600 each screen.
At the beginning, I thought it was because I use 4 screens, so I disconnected my 1680*1050 LCD , but the problem stayed the same: when I choose more than 800*600, powerdesk asks me to validate the change but nothing happens!

Actually, "matrox support" cannot say me what is the problem... Have you an idea?

Technical spec:
-windows XP, DX9
-xp 2800+, 1Go ram, 7800GT with dual-link DVI.
-TH2goD connected the GC with the dual link DVI provided.
-3 DVI lcds connected on th2go with single link DVI.
-1 lcd 1680*1050 on the other connection of the graphic card.

Here is my computer setup:



thx.

Amazing setup!!!

Have you tried to reinstall the drivers of the monitors?

Another option is to force the resolution by Control Panel.

At the NVIDIA's site I have found an information about max resolution:

# Dual integrated 400MHz RAMDACs for analog display resolutions up to and including 2048x1536 at 85Hz
# Dual-link DVI capability to drive the industry's largest and highest resolution digital flat panel displays up to 2560x1600

A hug,

Peter

pixel wise 2560*1600 has more than th2g's 3840*1024, and it's actually based off a single monitor from a dual-link cable spec. the card itself should work fine.

have you tried the dual2go modes and see if those work? like just 2 monitors used.

The 400MHz RAMDAC can push more pixels than DL-DVI.. if you reduce the refresh rate to 60Hz.. and use reduce blanking...

Besides DH2Go D and TH2Go D can push more pixels than 2560x1600... as both support 3840x1200pixels... the later also uses DL-DVI to push digital info.

Thanks for the advices, I'll try to do dual mode as the first step of my investigations...

Another question: Is it possible to do 1680*1050 + 3840*1024? And if it is, with which setup?

output1 to th2g and output2 to 1680x1050 monitor should do that, it won't join em for 3d games and such though, just desktop. windows will still see 2 monitors.

I have the same problem, I though it was my 6600GT DVI output.

I don't believe 6600gt supports DL-DVI... unless specified by card producer/maker.. not all 7800gt have DL-DVI output too..

Output from DH2Go and TH2Go have to be the same/identical resolution
