So I got my scratch and dent UB820 heater fun Crutchfield and as usual I can't find a blemish on it. It's a great 4k player for sure and incredible picture, definitely better than my old Sony X800. The HDR optimizer is very cool. I'm still trying to fully figure out all the settings. I thought you could choose between a high luminance and medium to high an OLED or projector? I couldn't find any of those settings. Dolby Vision looks just stunning though, that's really the show here with this player.
