Ok so if you use EDID 8 it's normal Xbox or PS5 does not want to offer you HDR for games, since it will only offer if seeing 4K60 422 12b support.Okay, got it working. I am actually on edid 8.
So basically all you have to do here is to reflash firmware (to restore default settings, or reset to factory default from GUI config page)
Make sure default custom EDID 1 is selected and make sure you have set quick preset for your PJ: HOLD RST and press INP 3 times. (refer to quick preset page in usermanual if you prefer something else, like if you prefer COLOR and CHROMA over resolution ,then may be HOLD RST and press INP 4 times is better for you)
If problem, try to take GUI screenshot when signal is passing thru.
