Flickering screen - Intel NUC11TNKI50002 (via HDMI)

[bpc]

Hello!

I'm having issues when connecting an Intel NUC to a monitor (HP 24f) via HDMI.

In the past I was able to have that connection established without trouble but recently (since the 24th of October) the screen has been going on and off and the image appears to be duplicated with a slight offset, this seems to be more noticeable when I move the mouse (I also have tried with different mouses and without peripherals at all).

- When did you buy the unit?

- My unit was bought in July 2022 (Intel NUC 11 Pro UCFF i5-1135G7)

- Did this configuration (NUC+ one monitor on HDMI) use to work fine before? If yes, was there any recent change related to the point when the issue started?

- Yes, it has worked in the past. In the meantime I have just been updating the software when suggested by both Microsoft and Intel.

- Could you please provide a video or some pictures showing this behavior?

- A video of the behavior is attached.

- Have you tested your NUC with a different monitor, a different HDMI cable or a different power brick?

- Yes, I tried a different unit of the same monitor model, a different HDMI cable and a different power brick, the problem persisted. This behavior is also reproducible on both NUC's HDMI ports.

-Did you turn the NUC off and then back on?

-Yes, this seems to temporarily fix the problem. However, after some time it reappears.

Any help is welcome.

Hello bpc,

Thank you for posting on the Intel® communities.

I am sorry you are having issues with the connection between the NUC and the monitor. I will be glad to assist you.

Please provide the following information:

• Does rolling back to a previous driver version solves the issue?
• Is the issue happening randomly or when running a task in specific?

As well, perform a clean installation of the latest graphics driver 31.0.101.3222 https://www.intel.com/content/www/us/en/download/739618/intel-graphics-dch-driver-for-windows-10-and-window-11-for-the-intel-nuc11pa-nuc11ph-nuc11tn-nuc11eb-nuc11btm-nuc11db-and-nuc12dc-nuc12ed-products.html

Hello Steven_Intel,

Thank you very much for the quick response.

• I haven't tried rolling back to previous versions, however I have checked and the version installed is the 29 (don't remember the numbers following the dot, if you want I can check it again), so it is not up to date even though Intel Driver and Support assistant says that there is no updates pending.
• The issue happens randomly, there is no obvious pattern.

I will perform a clean installation of that driver as you suggest. Allow me some days to test the system, as it is quite erratic I don't know when to expect the problem to happen again. If it happens again I will let you know, if not I will accept your answer as solution within 15-30 days.

Best,

Bruno
