Black border when connecting laptop to bigscreen (not fullscreen)

[nobb]

Sometimes, I like to bring my laptop downstairs and connect it with a VGA cable to my Sony kfe50a10 bigscreen tv. The specifications for my tv says it supports a maximum resolution of 1280 x 720, which is exactly what I am giving it. However, there is a 1-2 inch border on all sides of the picture. I was wondering if maybe someone has any suggestions. I have already tried stretching the picture on the ATI catalyst software, as well as messing around with the zoom and picture settings on my tv, but I still cant get the picture to be fullscreen. I am starting to suspect maybe its because I am using a VGA cable. My laptop only has s-video and vga output. Do you guys think getting a vga > dvi converter, then using a dvi cable will work? Any suggestions welcome. Thanks.

It may be something you have to change in the TV service menu. Check the relevant AVSForum thread...

Stick to the VGA for now. Are you running the proper refresh?

Yes, 60hz is the only thing my tv supports.

Well, you definitely want 1:1 mapping, so avoid stretching or zooming. Have you tried the HD resolutions in Catalyst Control Panel (720p60 or 1080p30)?

EDIT: Also, update your video drivers to make sure you're not missing out on auto recognition. A DVI might be better implemented, but a good VGA to DVI was pretty expensive last I checked. Might see if someone could bring over their PC to try it.

For the VGA connection make sure 'Analog' is selected on the TV setup screen.

i get the same problem doing S-video out to a big screen plasma, at all resolutions

i think DVI would help you, but i havent tried it

It's probably because you have a 1366x768 set.
