17" is probably either 1024x768 or 1280x1024. Right click on the desktop and select properties then settings and try it on either of those two and see if it helps. You might also try clicking on the Advanced button and set the refresh rate to 60 hz.

I can give you more detailed instructions with pictures if you want.
