Corrupt EDID?

[DrNick]

Hey guys sorry if this is the wrong place to post this but I am starting to lose my mind with this. I have, for years, used this tv with my pc and have never had any issues. Always used a generic pnp driver and nvcp always seen it as a Panasonic tv.
Out of nowhere it has decided to no longer work the same way, with windows installing a generic non-pnp driver, and nvcp seeing it as a digital display. This forces it to a max 1024x768, no hdcp, and no sound.
From what I have seen online I am guessing its edid programming/chip may have become corrupted? I have tried everything possible with no change and I have included what I pulled off of it with MonInfo. If anyone can tell me if something is up with it I would greatly appreciate it.

You can try making a custom resolution in the nVidia control panel. Though that probably wont fix the sound issue.

Thanks, I have narrowed it down to the tv simply not wanting to work with my pc anymore. If I plug it in while the PC is running, then all is well. Once I restart or switch inputs on the TV it loses it completely and I have trouble getting it to even detect it again.
I have tried everything possible and a usb to hdmi adapter will be my last step with it. All tv inputs work flawlessly with my tivo and ps3, including hdcp

Edit- Updated to the latest official bios from both evga and zotac and now it seems to be working on the master card (evga) but too lazy to switch them around to test the zotac. I will keep an eye out but so far so good. Damn this makes me happy
