I have a new home built pc with an ASRock Fatal1ty motherboard and an Intel i7-4790 cpu. Connected to the pc by HDMI-cable is an ASUS VS247H-P display.

My problem is the display is not turned back on when the pc resumes from stand-by. The pc enters stand-by as expected after a set idle period, the display bekomes dark, and the display led turns from blue to orange. However, when I activate trackball or keyboard, and the pc resumes, the display does nothing at all.

Hope an experienced person can point me in the right direction. Any suggestions welcome.

My PSU is an Energon EPS-650W CM. It does not seem to be on the support list. However, I have tried leaving out the following in bios (which is v. 1.10):
1) Package C State
2) Package C State and SupportC7
3) Package C State and SupportC7 and C6
None of these helped. So I guess Haswell incompatibility is not the issue?

I still have not found a solution to my display wake-up problem. In the mean time I have updated my motherboard bios to P1.50, which did not solve the problem.

Would be grateful for any suggestions.
