Hi, I own the 75" Q900R (Q900RA to some) and just bought the Xbox Series X and it is showing as not supporting 4k at 120hz. Why is this? I have updated latest software, have the updated OCB, game mode on and have UHD Colour on. All conversations with support state that 4k 120hz is supported by the TV and they have no solutions thus far - they are investigating the issue. I really hope I have not been mis-sold by Samsung when they stated that HDMI2.1 would be supported with the upgraded new OCB. I would rather not have to complain or raise a mis-sell with Samsung as I really like them as a brand and love the TV overall but this TV was not an insignificant amount of money and I trusted Samsung when I bought the TV that they would sufficiently implement HDMI2.1.
