resolution large

[Neil on Xorg]

Hi, 

I don't know if I joined the right mailing list. I got my X to be displayed 
on my hdtv @1920x1080 interlace resolution. However, the image or a terminal 
screenis larger than my hdtv screen. I am not able to see the title bar of 
it, I don't see the taskbar either. I don't know if there is a fix for this 
but I would be glad if someone can help me. I've research and found out that 
they call it overscan. 

Please help 

Neil
