Intel ARC Graphics HDMI external connection keeps blanking screen

[Andre_Luiz]

Hello Everyone.

I got a new laptop at work, about one month ago and it was working great until Tuesday.

I left the office with everything working and now, the monitor attached to the HDMI connector keeps disappearing the image, from time to time, with no pattern, it may take 1 minute, 5 minutes or do it every 30, 20 seconds.

As there was no changes in the Windows/Laptop, cables tested and swapped, monitors also, I called Lenovo and they replaced the motherboard.

The issue persisits even after a new motherboard was installed, so, my best guess, it is a driver issue.

I have ran Lenovo Vantage and got also from here, Intel's support page, the newest drivers. but none solved the problems.

The laptop is a LENOVO 21M8000XBO and the Intel Graphics is this:

Intel® Graphics

Detalhes do driver Atualizado

Provedor: Intel Corporation

Versão: 32.0.101.8135

Data: 2025-09-30

Has anyone faced the same issue with a solution?
Thanks in advance,

Best Regards
