Last night windows update installed an update and then it restarted my computer while I was asleep. When I got on this morning my display had been changed from 1680x1050 to 1440x900 which is lower quality and does not fit on the screen correctly. I have a Sony KDL-52XBR4 LCD tv. Monitor Type indicated in Display Settings: Generic Non-PnP Moniter. Display Adapter: NVIDIA GeForce 6150SE nForce 430. Driver Date: 05/22/2008. Driver Version: 7.15.11.7521 (most current driver). Bios Information: Version 5.61.32.25.2 OS: Vista HP 32-bit. I have for 3 years now used 1680x1050 as the resolution. Now it has 1680x1050 as a hidden mode. If I uncheck 'Hide modes that this monitor cannot display' and then select the correct resolution it obviously will not display it correctly even at different refresh rates. No other resolutions besides 1680x1050 look acceptable. What are possible solutions to my problem?
