Question for the forum. OPPO UDP-203, Sony 940E, and NVidia Shield owner here. I just recently updated my 940E firmware, and recently witnessed some unexpected behavior, I wanted to see if someone could help me understand why/how it happened and if this community thinks its related to a setting on my OPPO 203.
I bought Black Panther in 4k UHD. Played it back on my OPPO 203. The little "HDR" flag was visible when I navigated to "Picture Adjustments" on my Sony 940E. But my Sony didn't automatically drive my Brightness setting to "maximum" (100) like it normally does for an HDR source when in either CinemaHome, CinemaPro, or Custom video settings. I tried all 3. It didn't work for any. I had to do it manually.
I flipped over to my NVidia Shield, which I have connected via HDMI In on my OPPO 203, and then out the dual outputs to my Sony 940E and AVR in parallel. With my Shield set to output 4K BT.2020 4:2:0 10-bit, I flipped a Netflix "HDR" stream on (Marvel Avengers, I think), and not only got the same "HDR" flag in my "Picture Adjustments" window, but also got an "HDR-10" popup in the top right corner of the screen as the stream began. And unlike with my Black Panther disc, my Sony 940E clicked into "Maximum" brightness with my Sony set to CinemaHome, CinemaPro, or Custom... just as I thought it was supposed to.
Do I have something configured wrong such that a "flag" isnt' coming out of my UDP-203 telling my Sony 940E that this is an HDR-10 signal and to get "HDR" settings for maximum brightness?
