Hi, I have 58PUS8505 connected to PC with RX6950 XT GPU. Gpu recognize tv as fhd, I can't use amd rsr in 4k becouse of that. How to force 4k edid on tv to make it handshake with gpu as 4k?

EDIT:
I found this patch with custom 4k60hz EDID but author says it's only for apple. How to make it work with windows PC?

I already did it, it only activates HDR, pc still see tv as fhd. Problem is 100% edid. I don't have skills to compilate proper files with 4k edid info.

I kind of fixed it. I installed Custom Resolution Utility on Windows and added 4k resolution to EDID, this app tricks system by changing received EDID info. Of course TV still sends FHD EDID. Curse you PHILIPS for not optimizing software correctly!
