ATI Radeon 9550 / X1050 Series Resolution Problem.
I have an ATI Radeon 9550 / X1050 Series card. On VGA I can reach 1280x1080 however on DVI I can only reach 1280x720. I am using a Sony DDL-32ex500 as my monitor. I have the most up to date drivers from Ati. All I get from my tv above 1280x720 is a black screen. Any ideas?

In device manager is your card listed or does it show standard VGA?

The card is listed in device manager. I even tried un-installing the driver and tryed the standard vga drive and i still can't get 1280x1080. I know its not the TV because I can connect other devices to the same port and display 1080P. In the CCC I added 1280x720 or I would not be able to see anything. I am starting to wonder if this is a windows 7 problem not just driver related.
