Problem with Dell Laptop...Please help?

I play the old warcraft 3, and as i move from one better graphics card to another, it got wider and distorded. Eventually, it got flat and i can't change it without gettting another monitor or a lesser graphics card. To make sure you have the latest graphics driver, go their website, a href="http://support.amd.com/us/gpudownload/Pages/index.aspx" rel="nofollow"http://support.amd.com/us/gpudownload/Pa…/a and make the selections to get the zip file. Should be self-extracting and itll install it for you. After that, make sure that the image on your screen is centered correctly, not sure about laptops, but monitors have the option of moving the image left and right, causing blank or "black" bars to appear on either side.
