Hi guys,
I believe most of us who use Laptop with any ATI Graphic Card will face this problem. Which is When you run your game for example Warcraft III or any game with fullscreen mode, the screen didn't stretch and you can see black lines with the width about 3CM on the left and right of your games windows. This is caused by your graphic card setting which force your games to run under the specified aspect ratio.
Refer picture below if you don't understand what I meant about the game run under Aspect Ratio.
