Broken card? Can one port on AMD:6950 graphics card break and only display Generic-Non-PnP resolutio

[theDUFF]

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.

i think this is software, if the port was broken i dont think you would get any signal at all.
i would say uninstall drivers, go to device manager delete it(the generic thingy) and shutdown the pc, then unplug the GPU from the mobo, and reseat it again, start pc and reinstall drivers.
also if it says Generic-Non-PnP monitor, then that must be the monitor, are you sure the VGA device isn't hidden somewhere as generic too ? so if you update driver manualy from device manager pick the monitor drivers, not the GPU.

Should not matter while pc is still on plugging unplug

So either damaged port / cable

or maybe you could reflash the bios had a few cards in the past with similar issues bios reflash resolved it

Thanks. It took me a while but I've tried all of this (apart from the re-flash) and I could not fix the issue. MY PC is rather old anyway so I have decided to buy a new one . I'll be posting a Q about that shortly...
