2nd display LCD tv can not run 16:9

[skchi]

I have a main monitor and a second LCD tv connected to my display card, my card is ATI 4870 and no matter which resolution i set, the lcd tv just not displaying in 16:9 ration, it can only run in 4:3 which leaves 2 black edges on the side unused.

Im running it on DVI - D-sub cable, is it a cables problem? or my lcd tv does not support pc 16:9 resolution?

my lcd tv is panasonic viera 720p. the best resolution so far i could set to is 800x600

please anyone can help me set it to 16:9 ration?

thanks!

What are your settings in Catalyst Control Center? I'm not at home so I can't look how mine are set.
