My setup consist of a Win7 MediaCenter PC with an AMD card. The primary display goes to a VGA screen that I use as the control screen. The projector is setup as the secondary display. I am using the extend function. I keep MediaCenter full screen on the projector screen.
When I power on my system the PC is switching MediaCenter to my control (VGA) display. After a projector power off MediaCneter is not switched.
With the old projector the MediaCenter remained on the projector screen even when the projector was switched off. At least it didn't jump to the VGA screen.
So, the issue is that wehn powering on the projector the full screen MediaCenter app is switched from the projector screen space to the VGA space.
I checked all the stings and couldn't find anything "do not detect display". Catalyst is set to detect displays manually. Also, on the projector side I tried to disable any HDMI power smarts.
Any help is appreciated!
