Intel Nuc , displays will not come back on after the screens turning off.

[idata]

After leaving the intel nuc alone to for 45 minutes the displays turn off. However it cannot be woken up and the only way to get the computer back on is a hard reboot. I have remote management software on this pc and can still send command to such as reboot etc.

Seems to be some sort of display driver issue. It is not set to sleep at all , in the short term i have turned off the settings that shuts the displays off. It has happened across two different NUCS over my sites. Started on monday , Updates were done last wednedsay.

Just want to add more details for other who experienced this problem

• HDMI: min-hdmi (nuc) to hdmi (TV: Samsung UN65KS8000FXZA) has inconsistent flickers - very frequent
• I've been using DP instead of HDMI for about 10 days. It has consistently been working well compared to using the HDMI connector.
• I am using a mini-DP to DP and then DP to HDMI adapter, and the same HDMI cable was used after the adapter.

Weird thing as well is that I originally had this issue with Intel NUC5I5RYH. Well, I have just switched to a new NUC7I7BNH and it has the exact same problem as described in this thread.

It is a newly formatted machine with WIN 10 Pro fresh install.

• HDMI: hdmi (nuc) to hdmi (TV) random flickers of screen
• I have to use a USB-C to HDMI adapter and the filckers again has gone away.

I suspect that there is a problem with the HDMI driver/hardware with the Samsung displays.

Hello LeRatLuciano and Wakkigy,

Is it possible for you to test different monitor/TV maybe from different manufacturer? I will try to reproduce the issue in our lab, but what I have available is a LG* 4K TV. Regards,Fred D.

Unfortunately I only have access to this Samsung 28" 4K monitor.

Hello Wakkigy and LeRatLuciano,

I was able to reproduce the flickering issue with an Intel® NUC NUC7i7BNH and a LG* 55UH8500 4K TV through HDMI. I will do further research about this and then I will post updates on this forum thread. Regards,Fred D.

You rock. Thanks!

Hello LeRatLuciano and Wakkigy,

This issue has been reported and engineering is working on finding a solution for it.

Can anyone refer me to the new URL for a solution to this issue? I've been stuck for three years with a NUC with this issue, so I'd love to know the fix!

I have the same issue on Windows 11, After testing some of the solutions on the internet.

I turn off  all USB Hub 3.0 / 3.1  power management settings:

X Allow the computer to turn off this device to save power

The issue was resolved for me, for your reference.
