I'm using my computer as a cable box, cable card tuner. Can only use one display at a time because of HDPC etc. I'm trying to make it possible to view a 27" crt tv with 480i component capability. It seems I can't change the resolution to 480i on my HD 6670 thru catalyst 13.1. It seems that I have to select the monitor first then change the settings, thats not going to work. One monitor is disabled and the other one is # 1 monitor and vice-versa. I'm thinking that my flat screen has to stay #1 and monitor #2 and CRT #3... How do I accomplish this?
