My laptop: Alienware 18, 780M SLI, Windows 10 x64.
The screen works if i switch to integrated graphics.Here's what i've tried so far:
Regedit, set VgaCompatible flag to 1 (http://en.community.dell.com/owners-club/alienware/f/3746/t/19470433)
Replaced mobo (just had a working mobo lying around )
Used only one 780m, then replaced it with the second one in the same slot
Different nvidia drivers
No HDMI signal message on the screen all the time. Any help would be much appreciated!
