    Screen will not wake up after sleep/suspend


      My NUC5i5RYH is connected to a Benq 27" QHD monitor GW2765 via mini DP - DP cable. Running W10.


      Issue: When waking up a black screen from sleep within relatively short time after going into sleep mode (5-10 minutes), there are mostly no problem. When longer time one of two things happen, 1) either the screen shows up as desktop and icons but without the windows, or 2) the screen is completely black.


      I am - most of the times - able to solve issue 1) simply by pressing the on/off button on the monitor, first off and then on. Sometimes I need to unplug the DP cable for the NUC and re-insert


      Issue 2) requires that I physically removes the power cable from the monitor, waits until the led light has gone out completely, and then re-inserts the power cable.


      Have tried to ask Benq support, and they do not know this issue, but has offered to bring the screen to their lab under warranty. However, I suspect this is an issue with the NUC's port, so sending it to Benq will probably not solve anything (my colleage with the exact same NUC and exact same monitor has the exact same problem)


      Anyone's got an idea how to solve this? Due to the amount of unplugging and plugging (20-30 times a day) I am fearing that over time the ports will be destroyed or eventually some voltage issue might occur and damage either the NUC or the monitor.

          Hello mlun58:


          Thank you for contacting the Intel® Communities.


          This is a known situation with Display Port.


          Not being able to wake from sleep while using Display Port has been an issue for a while now.


          Have you tried using a different interfase in the NUC to connect your monitor (Mini-HDMI 1.4a)?


          Also, you could check this thread that has the same theme.

            I have struggled for a while earlier to get HDMI to work: Bought different cables, tried other graphics drivers, upgraded BIOS etc., only to give up using HDMI. Seems to be due to Intels use of an ancient 1.4a HDMI technology. DP seems to be the least crippled way to get a display of of your alpha product, so guess I have to live with it as it is.

              I tend to think that it's the monitor problem, not NUC itself. I have 5i3RYH (i.e. of the same generation of NUCs) model on my own and it works with the display connected via DP quite correctly

                Hello mlun58:


                Would you please advise me with the issue you are having with HDMI? The first thread mentioned DP only.

                  Hello Esteban C,


                  I am also having a problem with the HDMI connection not waking the monitor after a long off period, usually overnight.

                  My monitor is Acer T232HL using HDMI cable direct from NUC5i7RYH.  Waking the monitor works fine after short periods of being off (1-2 hours), however, after long periods (8-10 hours) the monitor will not wake.  The only way I have figured out to get the NUC working with the monitor is to hold the NUC power button until the computer shuts down and then reboot.

                  I have the NUC setup to shutdown the monitor after 5 minutes and to never go to sleep.

                  Edit: I have restored my system to Win 8.1 and no longer have this problem with the HDMI connection.  Must be an issue with Win 10.
