Fix Overscan on 720p when connecting to HDTV
 

Hi!

I'm using a DisplayLink USB Video adapter to connect my laptop with Windows 7 and a Mobility Radeon 3400 (with only VGA output) to my HDTV (without VGA input). In 1080p, I can adjust the format of my HDTV to show the desktop correctly. But on 720p, is a noticeable overscan.

The Catalyst Control Center doesn't recognize the HDTV connected trhoug DVI-HDMI cable as a HDTV, therefore it doesn't show any tool to fix the overscan.

Is there any fix to this problem through the DisplayLink driver software?
Any "tweak"?

Thanks
Agustin
