I just bought the X800 and hooked it up to my Epson 5040UB. Both are capable of HDR10, yet it seems intermittent that the HDR signal goes through. I put on THE REVENANT 4K. I checked the Epson and it was listing the color signal as 2020 SDR. I ejected the disc, put it back in, hit play, and this time the Epson read the signal as 2020 HDR with a much improved image. I've tried this several times and it seems to be a total crapshoot whether the signal is coming through as HDR or SDR. Anyone have any thoughts on why this might be happening or if I am doing something wrong? So far no way to know if it's the X800 or the Epson 5040 that is the problem.
