is your motherboard Bios up to date ? the lasted version is 1.20.
Go to bios menu Advanced and set...
primary Adapter = iGFX
share memory = select Highest MB
iGPU Multi-Monitor = enable
Render Standby and Deep Render = enable
Yes...Bios is up to date.
And all the option are enabled (with 1024 MB as "share memory").ò
I made a few test and I realized that the problem is only when I choose the "clone mode" (win+P).
The system don't let me choose my monitor as primary output. Even if I choose the monitor, when I do "win+P" and select "Just Computer", I can see only with my TV.
I tried choosing "Just projector" and in this way I can see with my monitor. In this in this case it seems there are no problems, but I would like to set "clone mode" all the time (like I use to do on my old PC).
have you tested with your TV on HDMI and your Display with DVI connect ?
My current cable is too short to try. I'll buy a longer one and I will try in a few days
