Try a driver update first instead of a whole new card.  My wife has an i8100 with the Mobility Radeon 7500 card and I updated the driver right off the ATI website (mobility Catalyst package).  The drivers from Dell are ancient.  You have to extract it to a temp folder and then tell Windows not to search for the new driver but that you have your own disk.  Then use the browse to navigate to the temp directory where it is at.

 

Does this window shrink thing happen with just one particular game?  I've played a few games on ours and it has never done this.

Try this first. Hit Fn+F7. If your video driver is new enough that should do it. I just found out it was that simple. LOL

 

Things that make you go DOH!!!

I had the same problem but I just fixed it. Roadi is correct when he says to make sure you have the latest video driver installed. You can get it here:

Just select your operating system, click "Find Downloads" and then download the video driver for your adapter. I assume you have the nVidia GeForce 2 GO? The following procedure is for that driver.

 

1: Install driver and reboot. The Dell splash image should be small and centered on your screen if what I suspect is in fact the problem.

 

2: Once you're back to your desktop right click an empty part of the desktop and select "Properties"

 

3: Click the "Settings" tab and then click "Advanced".

 

4: Click the "GeForce 2 Go" tab and then "Flat Panel Display" on the menu that pops up on the left.

 

5: Click "Use Display Adapter Scaling" then "OK" on both windows to clear them.

 

If I'm right your problem should now be gone and you'll get full display on your games.

Let me know if it works, Ok?
