Hi all, yesterday i received my new GTX580 and finally i've got it running perfect at 5040x1050 with TH2GO digital edition on Win7 64 ultimate.
My system has 4 monitor, one Benq 24" i used to work connected to first DVI port of card, and 3xBenq G2200W with TH2GO connected to the other DVI port.
I have the same problems as many of you, i only could set 5040x1050 from Nvidia panel, but no from Windows panel or Powerdesk, but after many tries, I´ve got it! :)
Here are the steps i did:
- Uninstall all previous drivers and Powerdesk
- Update TH2GO with latest firmware (Dec. 8, 2010)
- Install latest Nvidia drivers (270.61-desktop-win7-winvista-64bit-international-whql.exe)
- Restart
- Create and set custom resolution of 5040x1050 57 or 59hz from Nvidia control panel.
- Now install Powerdesk 2.07 (Powerdesk verison v64_gxm_2_07_00_031r2_whql.exe). Once it has finish, run it to detect monitors. Now it ask to restart ("Powerdesk has detected changes and need to restart....).
NO RESTART HERE!
- Leave this Powerdesk window open, and launch Powerdek from Start Menu. Go to MODE MANAGEMENT and select 3x1650x1050 and click "APPLY".
This is not my system, i only attach this picture only to see where to set it :)
- Then cancel the previous Powerdesk windows asking for restart.
- Restart
- Now system start at 5040x1050 and Powerdesk is correctly set! :). I didnt received any more messages asking for restart due to changes detected.
Hope it works for you guys, sorry for my english
