When I first installed Windows 7 Build 7100 had available screen resolution 1600 X 1200 on my Planar 2010M DVI with GEForce 6800 GS. Somewhere along the way max became 1024 X 768, not sure if broken by nvidia upgrade or Windows Update. The monitor is listed as the Generic digital non PNP. There are no monitor drivers available for this monitor. Stopped by brick and mortar and picked up a 9400GT, now I can choose 1280 X 720 which scrunches, no help. Have the latest 190.62 installed from nvidia, have spent the day trying both cards, powerstrip solution from another post, etc to no avail. Attached an older smaller Sony monitor via the standard VGA and voila it is recognized. It becomes obvious this is either nvidia but more likely the monitor driver in Windows 7. Any suggestions or help much appreciated.
