M1 Pro display replacement and XDR/HDR

[jacksongoode]

After a repair where the replacement used a genuine M1 Pro screen but wasn't Apple authorized I believe the system isn't recognizing it as a native panel and I don't see the BetterDisplay XDR profile. However both ProMotion and True Tone work fine.

I was wondering if there is a way to edit the EDID display information to make MacOS recognize the display? I'm sure Apple's configuration tool post repair is doing something like this for the displays.

Sadly no, the display's EDID in Apple Silicon Macs is only a rather simple placeholder with some timings listed, so a pairing issue cannot be solved this way. :(

Ah ok. Do you know of other solutions to this issue? I'm you're more familiar than me on the matter. I find it interesting that some of the functionality is retained while others appear to be rejected.

I am not familiar with the process, but I know the panel must be paired and calibrated after the installation (afaik sometimes without this the panel does not look good as various settings like uniformity correction varies by panel - but this might be relevant to other MBP models, not sure.)
