Hi I've been using my dell for a couple of months and it works great. Today I changed the connection to DVI (instead of the VGA) (I have a Geforce fx5200 128 Mb). 

 The problem is that the native resolution (1680 x 1050) doesn't "enter" in the desktop, I mean I don't see the whole screen, I have to move with mouse towards a border to "pan" the screen. Why does this happen??

By the way, I had to do this because in 3ds max I had a  "blinking" in the screen that just "blowed up" a window of the program from my view (withouth closing it, of course), and i had to close it and re open it.

Thanks for your help!
