Flashing screen with Intel UHD graphics and latest driver

[SteveRo]

I'm running Windows 11 Pro 26100.4351 with all Windows updates installed. Everything has been working fine until a few days ago when the screen started flashing and this appears to have followed an update to the graphics driver (now running 32.0.101.6881)

I've tried running DISM /Online /Cleanup-Image /RestoreHealth and sfc /scannow to check for file problems and none were found.

I've run the Intel Driver and Support Assistant and it confirms I have the latest driver.

I've run the Intel System Support Utility and I've attached the log file.

The computer dual boots to Fedora Linux and there are no problems there so I'm pretty sure it's not a hardware fault.

Any ideas about how I can fix this?

I understand that you're observing issues with the latest driver 32.0.101.6881. To address this effectively, please share the information below.

1. What was the last known working driver version?

I haven't kept a record of driver versions and I tried reinstalling Windows so there's no option to roll back - there's only the latest driver available.

The computer is a mini PC plugged into a Samsung TV.

I've attached a video showing the screen flashing - this is quite a steady flashing; sometimes the flashes are less regular.

Hello SteveRo,

Thank you for the update.

• As per checking with your SSU, the model of your mini-PC is not indicated. Please confirm the exact model.
• Is your operating system up to date?
• Have you performed a Clean Installation of the Intel Graphics driver?

Thanks for this.

The PC is essentially a "no name" mini PC from AliExpress. It is described as "SZBOX S1 Mini PC Stick 12th Intel Alder-N Lake N100 Windows 11 DDR5 16GB 1TB NVMe SSD WIFI BT Desktop Pocket Mini PC Stick" and I think it's made by Chatreey.

I've checked Windows updates and everything is up to date.

I did use the Driver Deletion Utility to remove the driver before trying to install the new one.

I've tried screen resolutions 3840x2160 (recommended resolution), 1920 x 1080, 1440 x 900 and 1024 x 768 and they all have the same problems.

As more or less a last resort, I've tried installing the driver which came with the device (version 31.0.101.4146 dated 22/02/2023) and this appears to be stable but obviously it's very out of date.

Hello SteveRo,

Thank you for sharing all this information.

You mentioned that the driver version 31.0.101.4146 seems to be more stable. Does that mean that the flicker of screen doesn't happen? Also, what is the full model of the Samsung TV being used as well as the display cable being utilized?

Sorry for taking so long to reply - I've been away for a few days.
The old driver was rock solid - no flashing at all.
It's a Samsung series 7 TV, about 5 years old with a basic HDMI cable. Following your question, I've changed the HDMI cable.
I thought I'd risk an update so I've run the intel update utility and I now have the latest driver and everything is still ok.
I'm not really sure what's happened - I was sure it was a software problem because Fedora had no issues but whatever was wrong is now fixed so thanks for all your help.
