The XH90 series features 4K120Hz only for the PS5 at the moment according to the update notes.

I have asked many times this question and I seem to be given no answer? 

I would like a factual/ honest reply regarding evidence from experts in the field of TV,s and gpu also and with my own eyes experiencing unclear 4k 120hz gaming on the xh90 with both ps5 and xboxsx. Can the xh90 do native 4k @ 120hz ? Native meaning displaying all vertical lines of 2160p and horizontal 3840 @120hz refresh rate?. As tests from HDTV on YouTube and evil boris tech enthusiast both conclude it can not? Hence my repeated question on this matter. So I would like a simple yes or no?

Well, Sony say it can. Maybe it can be improved, but they say it can do it right now.
