I have a RX-A3050 that I am using with a Nvidia Shield. Even though the RX-A3050 is set to straight (no alterations in the video signal) there is a problem with Shield when using the Netflix and Amazon apps when HDR programming is played. There is no problem when Shield is connected directly to the LG OLED65C7P. A portion of the trouble report submitted to Nvidia is shown below. Please review and let me know if any of you have experienced this issue.
HDR programming, using Netflix and Amazon streaming apps, will not display properly when using the recommended settings (3840x2160, 59.940 Hz, YUV 420 8-bit Rec.709) for Shield . Under these conditions guide data, and the actual play back of the program will display HDR programming as Ultra HD 4K. HDR programming can be displayed properly on the program guide and the television if the HDMI settings on Shield are changed to 3840x2460, 23.976 Hz, YUV 422 12-bit Rec. 2020. On this setting all Ultra HD 4K programming is listed a HD in the program guide and is played back as HD on the television.
If Shield is connected directly to the television, using recommended settings, everything works properly. Please note that a Samsung UBD-M9500 4K Blu Ray player is connected to the RX-A3050 exactly as the Shield, and plays HD, Ultra HD 4K, and HDR programming through it’s Netflix and Amazon apps perfectly with no change of settings required.
