A device like my Gefen can emulate almost any EDID. And I have googled discussions about how to create and install a driver to override an EDID. Microsoft has some information on how to do it. But this is not something I have tried.
I assume the video card and driver version were the same as when the resolution was previously working?
It is onboard video (AMD A8 APU). Not sure about the driver version as I just went with whatever Win 8/8.1 natively uses. I tried updating video drivers afterwards, but it didn't work.
