How do I select the correct updated Video Driver?

I've been advised to get updated video drivers for my Dell Dimension 4500. But Dell's driver download site shows about five driver selections for my computer. How can I tell which would be best. My Monitor is newer than the CPU. It is a Dell E196FP 19-inch Flat Panel Monitor.

The reason for this inquiry is because my new HP Scanjet 4890 is conflicting with my present Monitor setup. When I click on the scanner software program called "HP Solution", my computer monitor goes black for about 4 seconds, and then it lights up again, but all the icons including the HP Solution screen, are in harsh, abnormally vivid colors. When I close that program, there is again a 4 second darkness, and then the screen lights up and is perfectly normal again.

Maybe the app below can help identify your video card and then select the driver to suit.

Don't really know much about updating drivers as I've never needed to do it.

Its the graphic card drivers you need to update not the monitor
