My display is a pioneer kuro so no 4K at the moment.
After reading this thread I briefly connected my FiOS cable box to my 203’s hdmi input last night.
There didn’t SEEM to be any discernible differences a/v-wise between the oppo’s hdmi input or directly into my Classe ssp800 input but I’ll do a thorough a/b test when I have more time.
I’d also appreciate it If anyone can chime in regarding setting preferences. A/V Settings were on default.
