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!
I'm confused too.
I have not tied it yet. I am still hoping for Win7 based solution.
I don't use dual displays, just a default and alternate. Also, I have the AMD driver in CCC set to NOT auto-detect the EDID.
Let us know!
This was super annoying for me cause I use a HTPC (Home Theater PC) and the PC kept moving the contents from one monitor to the other when I switched their inputs.
I also tried blocking the pin on the HDMI... that gave me even more issues, also adjusting Windows, Video-card or registry was a total moot.
Anyway, this device took care of the monitor detection..
I was surprised that it worked without any settings on the video card :)
