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! Edited November 7, 2016 by atjr Quote Link to comment Share on other sites More sharing options...
