Hi all, I seem to have this weird problem so if anyone can help I would be very grateful, thanks. Today when I started my PC I suddenly noticed that my resolution switched back from 1680x1050 to 1440x900! When I went in the Catalyst CCC to change it I don't have any option but instead it gives me as 1440x900 and 1600x1200! Same happens if I try to do it via Windows (btw I'm using Vista X64)! Another thing is that I noticed that the Catalyst CCC doesnt report my monitor correctly it just says "default monitor" while before it detected the correct model KTC2005 (it's a 20" KTC LCD)! I tried the following things with no success: I uninstalled the drivers through the Catalyst Install manager and installed newer ones (went from 9.2 to 9.3) but no thing changed! I also physically removed the card and re-seated and re-checked all the cables just to make sure but still no luck! I don't know if it is a software error (windows, drivers) or maybe hardware, graphics card or monitor! The previous day I installed .NET 1.1 but I don't think that would be the problem as it worked perfectly after that and I haven't changed my drivers since 9.2 came out so don't have any idea what could have caused this it just suddenly happened when I booted my PC! I'm trying to avoid reinstalling the windows so if anyone has any tip to help out or has had similar experience please help. Thanks.
