Overscan issue (?)

Hello, I connected my computer to a 32" Pilot LCD screen via HDMI-DVI connection.
There is a problem with the fitness of the display on the LCD (few areas are cropped). I tried using lowerscan, but unfortunately it lowers the resolution..
The native resolution is 1280*720 (16:9 ratio). I just can fit the display to the whole screen and keeping the native resolution.. What can I do? (more details about my problem: http://www.highdefforum.com/flat-panel-tvs/81071-having-trouble-my-lcd-view.html.

BTW, this is the monitor info (by Monitor assest manager)->

Looking at the other posts from your supplied link, it kinda looks like you're not getting 1:1 pixel mapping. The display is getting massaged by chips in the panel and it doesn't look like you have enough adjustments in your video card to compensate. VGA is a workable solution but as you've noted.. not as crisp as digital. A better shielded VGA cable will help a bit.
