Hey guys, I had a power outage here recently that lasted for about a second before the power came back on. My monitor (NEC LCD2690WUXi) is behind a surge protector, but I noticed afterwards that the monitor is no longer working properly. The highest resolution it'll do is 1280x720, and I've lost DDC/CI communication to the monitor. Windows only recognizes it as a generic PNP monitor, and a whole bunch of info in the EDID has changed. The code blocks below show the EDID info for the monitor from MonTool. The top code block is what the monitor currently outputs, and the bottom code block is what it was before, pulled from the registry. Note that not only have the timings disappeared, but the plug and play ID has also changed from NEC66CB to NEC66CD. I've tried power cycling, factory reset, and letting the monitor sit powered off overnight, but nothing seems to fix it.
Curiously, when I changed the from DVI port 1 (the port it was connected to when the power outage occurred) to DVI port 2 (the spare port), the monitor worked properly, but when I unplugged the cable later on and re-plugged it back into port 2, it started doing the same thing as port 1.
I can fake the 1920x1200 resolution by overriding the EDID settings and that will properly display 1920x1200, but I still don't have DDC/CI communication, which is really important because I need the hardware calibration. I can't re-program the EDID chip because it's either locked out or my graphics card (780 Ti) doesn't have the I2C ability to program it (PowerStrip doesn't detect an EEPROM). I'm pretty much turning to the forums as my last resort before I write this monitor off as unfixable. Anybody have any ideas?

(I was trying to get to the EDID chip to remove the write protect pin). Oh well, at least now I can pick up that 4K monitor I've been eyeing...
