I connected M9500 directly to the TV's control box. TV's source screen correctly shows the DVD player. I tried to play a 4KUHD DVD (Obvilion). M9500 shows a pop-up message that the TV is not supporting UHD playback. I used an HDMI 2.0 cable and think that is a good cable. Is there anything else I can check on DVD side or on TV side? Thank you, community, for your advice.
