I can't seem to get the TV to display 1440x900 as a PC monitor. My video card (Radeon HD 4870) can output that resolution in 60, 75, and 90 hertz. When I try to run 1440x900 at 60Hz It flickers twice and goes black. It automatically resets to 1280x768. I am using a DVI-to-VGA dongle to connect to the TV. I have updated drivers and am using Vista x64.
