daun86,

If you're running the DVI to VGA, you want to make sure that your video card is sending one of the accepted resolutions (listed in the manual) and that your overscan is off on the video card.

Most users can either update the BIOS or video card drivers and experience a bit of luck that way.

Dell laptops often have a Function F8 key combination before it will send the signal out, so don't forget to toggle that as well.

Keep me posted.
