One of the DVI ports on my AMD 6950 graphics card is only recognised as Generic-Non-PnP monitor and will only display 640 x 480
This is since the cable fell out and I plugged it back in with out powering down (my bad).
Setup:
3X ASUS VG236 monitors.
AMD Sapphire Radeon 6950.
GFX driver version : 15.20.1062.1004-150803a1-187669C / 2D - 8.01.01.1500.
Catalyst version: 15.7.1
win 7 (fully up to date).
AMD Phenom II X4 965 Black Edition.
Gigabyte GA-MA790XT-UD4P.
The problem occurred when win 10 was installed. I have tried:
1) reinstalling win 10
2) reinstalling drivers
3) powering down for 30 minutes
4) updating drivers
5) swapping between monitors and ports (all monitors are recognised and can display normal resolution from other ports on the card)
6) reinstalling win 7
7) override EDID settings using cru 1.2.6 (e.g. copy setting from working monitor over the one that is not working. I could not get this to work as after rebooting the PGP monitor is blank. It's s still listed in the Screen Resolution options, but the monitor is black rather than blue.)
8) Brand new DVI cable.
I have seen old posts that there is an option to ignore the EDID settings via. the AMD software suite. I do not see this option in the latest version of the drivers.
My conclusions is one port on the card is somehow broken and cannot display full resolution.
Is this possible?
Any further options to get this working appreciated. The only option i have left is to buy a new graphics card.
