Hi there,

I’m running fedora 40 on a Monster Huma laptop and now connected an external display over the HDMI port. However, the only thing the display shows is “no signal” and I can’t see it in the Display configuration UI. I can see the screen when I plugged in USB Type-C (Thunderbolt).

I checked monitor and cable on a non-Linux machine, they are working.

Could someone please help me out?

Cheers,
Sercan

I’ve had a similar issue that was fixed with a vendor firmware update to the linux box. Please check that you have applied all vendor firmware updates.

An similar report from at comunity.intel.com concluded with:

Intel: this could be related to the compatibility of the monitor.
and then:
3rd party comment: I’ve come across some instances where the GPU sends a format that is not supported by the display on HDMI. Or change the Color Space on the display. Some issues with HDMI is that it could be sending the signal as an AV timing or PC timing which have associated color space RGB or YUV (YCBCR)

Since both HDMI and USBc/Thunderbolt are hot pluggable, you could watch for different messages with journalctl --follow while switching cables. You don’t mention the model of your monitor, but you should look for others having similar issues for that model with linux.

I am sure this problem is common, I have seen similar threads.

I have tried multiple brands and models of monitors with the same result.

I am determined to solve this problem, I just need help.
