Windows 7 - 1080p Monitor not full screen

my laptop has an ati x1600 mobility card and is outputting via hdmi (mini dvi-actually) to an ASUS VH242H (full 1080p) monitor. When I had this connected running xp I had not problem with the screen resolution and size, but now that I'm running windows 7 the 1920x1080 resolution is available, but the picture doesn't fill the whole screen, there is like a 1" black box around the displayed screen.

I believe it has something to do with my display driver, I'm currently using the one provided by windows update.

download the driver direct from ati/amd, and see how that goes.

good luck!

also go into the display properties and enable "scaling" or "stretching"

The drivers for the mobility x1600 are not available at the website

I don't see any options for scaling or stretching in the display properties menu.

ATI Catalystâ„¢ Mobility Display Driver

How to
» Catalyst 9.3 w/ Mobility Modder? - Page 2

This task is no small feat. It has been performed successfully, according to the How To link.

Using the mod tool I was able to install the catalyst control center 9.8, but after the driver installed I kept getting a bunch of driver errors, and I could not select a resolution higher than 1024x1280.

So I'm back on the windows update ati driver and I just realized that using 1680x1050 fits the screen perfectly, so I guess I'm stuck with that until more support is added for my card (but I'm not very hopeful that they will even release an updated driver that resolves this issue, and other issues I've heard about with playing games).
