I don't think it's possible for the monitor to detect the GPU, and the EDID shouldn't change based on the source. If the EDID is wrong, the other GPU's driver might be ignoring or working around the incorrect information.

Do you guys think CRU can help me fix the wrong EDID information?

It might be possible if Intel's driver listens to EDID overrides for HDR, but CRU can't read extension blocks with Intel GPUs, so you need another method to get the EDID. See if this works and post the edid-dump.txt here if it does: https://www.monitortests.com/edid-dump.zip

Good morning and thanks for answering.

Yes, I agree, sounded weird from the begining.

I ran the edid-dump executable, it opened a command prompt or 2 and instantly closed and generated the dump. It is attached.

Hope you can help me!

Thank you very much!
