Custom Screen Resolution

[mablung]

I am having i bit of a problem. I have 2 Mecer 42t51 lcd tvs and a ATI HD 6670 both Support HD 1080P res but i can not get the dual Res of 2560x900. The closest i can get is 3360x900. Is there any software i can try to adjust the screen res manualy or any other suggestions may help.

PS the tvs are set to eyefinity

Are you using the ATI CCC control panel? AFAIK you an specify resolution there... Unless the TVs don't allow it. You might need them to be in "PC Mode"/no post procesing in order to use CCC's settings...

Looked in the CCC and in the group res it only allows me to use 3360 and up. I also did update the drivers to the latest CCC driver so it is also not a driver issue
