I am trying to use my new 42" panasonic plasma (Model TH-42PV500A) as the secondary display on my computer. I am using RCA connections, not RGB. The video card I am using in my comp is an ATI 9800xt. The trouble I am having is changing the resolution when outputing to the plasma as a secondary display on the vid card. When I attempt to change the resolution on the secondary display it always defaults back to 640x480. My secondary display, the plasma has a max resolution of 1024x768 and therefore I feel that I should be able to use this resolution whilst playing games etc? Btw this is my first post, I'm a virgin no more Thanks, any help greatly appreciated.
