If the TV doesn't scale the resolution you're sending it then you'll have to rely on the ATI card to do it. Have you enabled adapter scaling in CCC using the beta W7 drivers stickied in the Video Cards forum here?

Ive tried that yes. Nothing is working. The only way is to set the TV as the desktop

I'd suspect a bug with either the video driver or W7. Have you dumped the EDID for the TV to check it's timings? There are settings known as "front porch", "back porch" etc. that dictate the rasterization interval and thus the black borders. If you can force the monitor to use the settings that the TV needs I'll bet you can get rid of the borders. This tool will dump the TV EDID for you -- it's from the folks that make Powerstrip if you're familiar with that: http://www.entechtaiwan.com/files/moninfo.exe

Considering it worked perfectly with vista and vista drivers, I wouldn't considering tampering with the TV. I agree its the driver or Win 7.

Thanks for the replys

No tampering. Just finding out what the driver is getting from the TV in terms of it's capabilities. I think this is fixable -- we just need the information from that utility.

Well I ran that program on my PC monitor just to check it out and somehow I ended up with 3 monitors showing in windows display options. A new one called other showed up. So I ran it with my TV as default and it would only pickup the PC monitor.

Anyway I deleted the other monitor from device manager and now everything is working fine. Wierd!!

Thanks for all the replys

I think the secret is that you set the TV as default. It becomes the source of the display timings which are then applied to the monitor and not vice versa.
