NUC11i3PAH Display flicker issue

Yesterday I upgraded my NUC8i7BEH to a new NUC11i3PAH (Windows 11 - clean install). I am connecting to a Xiaomi 4K HDTV.

 

I noticed display driver artefacts (lines and noise) and upon checking I saw that I was running the generic Microsoft driver.  I downloaded and installed the Intel DCH Windows drivers (30.0.101.1340 / February 03, 2022) which changed the artefacts to occasional screen blanking: about every 30 seconds for about 2 seconds.

 

I am unsure if it is related - for the BIOS update the blue power light start flashing (about 1/sec) and hasn't stopped since.  I believe that this flashing is normal during the update but not after.  The display problems were occurring both prior and post BIOS update.

 

From my research there appears to be people having this issue on DELL laptops, but I can't really find much for the NUC11.

 

Thanks in advance.

I hope that Intel Support Agent will give you additional advice. In the mean tome in the SSU report I can see that you have installed  a "Citrix Indirect Display Adapter".  This is some default Display Adapter. Open the Device Manager, Display Adapters tab. Right click on Citrix Display Adapter and than click "Uninstall Device" (check "Attempt to remove the driver... " box).  Leave only the Intel Graphics Adapter installed. Reboot NUC and check.

The first driver to be installed after Windows installation should be the Intel® Chipset Device Software. So, uninstall the Graphics Driver, install the Chipset Software and the Intel® Management Engine Driver, reboot your NUC. Only then reinstall the Graphics Driver.

Good evening Leon, thank you for taking the time to assist.

 

I have done as suggested, uninstalled the graphics driver, installed the management driver, rebooted, installed the graphics driver.  There is no difference.

 

For the moment I have reverted to the Microsoft driver, which seems to be performing acceptably, possibly better than I recall from yesterday (no lines/artefacts now - perhaps some improvement from installing the chipset driver?).

 

if you have any other suggestions they would be welcome, the Microsoft driver is quite slow.

Hi maffu,

Please read my post above again. If I wasn't clear, the first driver to be installed the Intel Chipset Device Software. Next the Intel Management Engine Driver. After reboot, install the Graphics Driver.

You were clear, I didn't read it correctly.  I did it again, this time I installed the Chipset, followed by the management engine, rebooted and installed the graphics driver.  There is a slight improvement in that while the blanking still occurs the lines/artefacts are gone - it might be my imagination but it seems to blank the screen for slightly less time now - perhaps closer to 1 second instead of 2 seconds.

1. Can you test the NUC while connected to PC monitor, rather that 4K TV set? 

2. Are you using High Speed HDMI cable?

3. Try to connect to other HDMI input on TV.

1. I do not own a PC monitor.  I do however own a 2018 Sony Bravia HDTV and an older Panasonic HDTV - both show  as no input when I connect the NUC to them.

 

2. Yes, same cable as my NUC8i7BEH was using prior to getting the NUC11i3PAH replacement.

 

3. Tried HDM1 instead of HDMI3 on my primary Xiaomi UHDTV - no change.

The first thing to be asked by Intel Support is to send SSU report. I suggest, do this now and you will save time. Please download the Intel System Support Utility (SSU). Run the SSU scan (check "Everything") and save the results. The .txt file with the results please attach to your post.

Hi Leon - I attached the txt file as requested a few days ago, is there anything else I can / should do?

 

Thanks.

It seems like this might be the cause.  Since removing the driver the flicker is gone, still a slight about of screen tearing, but not much else.

 

I have marked this as the solution, if it is not I'll come back to you.

 

I assume I should probably inform Intel and Citrix if they are not already aware, how might I best do this?

Update: while the flickering is far far less common now, it does still occur occasionally.  I will log a ticket with Intel to proceed.

Hi @maffu 

While you waiting for Intel Support, I suggest to give one more try:

1. I assume that the the Citrix Driver was uninstalled. You don't need this generic driver, since you have Inte Graphics Driver which support your Integrated GPU.

2. I assume that the Chipset Device Software and the ME Driver are installed. 

3. Next, uninstall completely the Intel Graphics Driver and reboot you NUC. Since uninstalling in Windows 11 the drivers and prevent the old drivers to be installed again is not simple as it was in Windows 10, please see this video clip How to Uninstall Device Drivers in Windows 11to learn how to do this. After uninstalling the Inte Graphics Driver and rebooting your NUC, you should see there Microsoft Basic Graphics Driver. 

4. Only now, after rebooting you NUC, when you see the Microsoft Basic Graphics Driver, install the Intel Graphics Driver

 

Hope this will help

Leon
