I doubt it's the video card drivers, more than likely its the monitor's drivers. Did you install the monitors drivers??? TFT monitors need drivers to function properly. It should have come with a CD to install them. Another thing, when you go to the Display settings does it say something like Name of Monitor on Radeon 9200se, or does it say Plug n Play Monitor on Radeon 9200se? if it is the latter then you have to set up the monitor so it functions. In addition your resolution should be at lest 1024 by 768 as stated by Miz.
For your video card drivers try

The drivers to download are the Catalyst drivers, for Radeon.
