I have both NVIDIA Shield Pro 2019, CCwGTV and Firestick 4K. I play quite a few work videos (low resolution 720p 30 fps training videos) and my Samsung QN90A is the best upscaler for those. But if I use Shield or Firestick 4K, they all try to upscale 720p to 4K and none of them come close (even AI upscaler on Shield) to QN90A. I see Plex can preserve resolution and my QN90A reports it’s receiving original resolution. But my work videos are not on plex. I am simply using Airplay via Airpin pro. It has support for external video player. But Mx player pro, VLC, even Kodi built in video player, none of them seem to pass through 720p. My Samsung QN90A reports it’s getting 4K (Kodi can match refresh rate to 30 fps, but not the resolution) and video again looks bad. I can force firestick 4K to 720p and then get the desired behavior. But then I have to switch for each video. And videos are mixed with various resolutions.

Thank you!
