I just bought a new graphics card for my Asus P5GC-MX/1333. It's Sapphire Radeon HD 6570. It's works perfectly but it does not fit my screen. My monitor is Samsung SyncMaster B2430. I'm using HDMI port instead of D-Sub... I need help as soon as possible... Thanks.
What do you mean it doesnt fit your screen? If you mean the image isnt edge to edge on your monitor, than most likely you need to adjust your scaling option in AMD's control panel. Not sure of the exact tab its under since i'm not in front of my computer but look for an option that says scaling (or maybe its overscan), but it will be a slide bar that you move to adjust the picture to be edge to edge.
