I have my 6900 XT hooked up to an Asus PG32UQ to display port and I have a Sony Bravia XR 80K hooked up with an HDMI cable. The problem is if I turn off the TV or monitor the other one will turn off. I have to keep them both on all the time. I only want to use the TV for games so I dont want it to stay on all the time. Anybody have any idea what Im doing wrong?
