As the title says, I used to use a graphics card with a VGA cable and Windows 7 reccomended 1440x900, which is my native resolution for this monitor. Now that I have installed a new GPU (PowerColor Radeon 7950) and used a HDMI as opposed to VGA, I can no longer use my native resolution, and instead, am forced to use the reccomended scren res. of 1024x764, if I go to 1440x900 the screen gets all glitchy. I successfully installed the drivers and what not via the drivers disk.
