Windows 7 - Help ATI Radeon 3100

Guys, please help me... I have a notebook, Toshiba Satellite L500d-00f with a radeon 3100 video card. I noticed that some of my games even videos doesn't adjust to fit screen automatically, I've maxed the screen resolution 1366X768. What I want to happen is that whenever I will run a Game or a video it will fit to screen automatically without further adjusting game and video settings, would that be possible? I've been trying to figure out how to do that for almost a week. I've got the new Catalyst installed. please have mercy on me.

You can try clicking on Properties of your game and tell it to run Maximized.

I think he means that the game doesn't scale to the full LCD panel. ie if your LCD has a res of 1366x768 and you run a game at 800x600 to make it playable, the game displays with black borders instead of scaling up to fit the full screen.

Laptop screens unlike Monitors, don't have built in scaling. That is handled by the drivers on the GPU.
What drivers do you have installed. Is it Toshibas latest or yesterdays Mobility Cat10.3a.
Anyway, try opening CCC - Desktop & Displays - Right Click small laptop at bottom - Configure. You should now be on the LCD Screen Attributes page. Drop down to the resolution you want to scale and tick Enable GPU scaling - Scale image to full panel size and Apply.
This feature works well with DX9 and earlier games/Media Players, but may still have scaling issues with DX10/10.1/11.
