I have a problem with Apple TV 4k connecting via Oppo UDP-203. The menu is very sluggish and I see a lot of dropout in video and audio. I can't watch any contents on Apple TV 4k.
Has anyone ever experienced this situation like me? Is this a bug or glitch between Apple TV 4k and Oppo UDP-203? I updated both Apple TV 4k and Oppo UDP-203 to latest firmware.
Thank you for your help.
I own an OPPO UDP-203 and an Apple TV (and an NVidia Shield). Before I got my new AVR (which supports all the new HDMI video standards like HDR10 and DV), I was using the HDMI input and dual HDMI outputs to take my NVidia Shield into my TV (with HDR10 video) and AVR (with Dolby TrueHD or DTS-HD-MA) in parallel.
I never hooked my AppleTV up via the OPPO UDP-203 HDMI input for a simple reason: the Apple TV didn't/doesn't bitstream Dolby TrueHD or DTS-HD-MA, so I don't use my AppleTV for my 1:1 BluRay and UHD Blu Ray rips. So I just took my AppleTV directly into the TV via HDMI, and then came back down to my AVR via TOSLINK, which got all of my Streaming Subscriptions that have HDR10 or Dolby Vision but no lossless audio to my TV with full PQ, and then out of the TV and to my AVR with their Dolby Digital 5.1 audio in-tact (I don't have/do atmos, fwiw).
But some of the experiences you are describing with the ATV4K via the OPPO UDP-203 HDMI input are very familiar to me to what I experienced using my Shield through the OPPO. The screen and GUI would get sluggish. Once every week or two video or GUI would get stutter-y/choppy and the only thing that would fix it was a reboot on my Shield. But the problem wasn't with the Shield, it was with the OPPO's HDMI-input. Ever since I got a new AVR, and made my signal chain Shield--> new AVR --> TV, all of the issues with sluggish GUI and weekly reboots went away. Also, at least at one time, the OPPO 203's HDMI input couldn't pass Dolby Vision, only HDR10. The Shield only supported HDR10, so I wasn't loosing anything using it that way, but if you're doing that with your ATV you might be sacrificing Dolby Vision support, too.
Unless you're doing something/using your AppleTV in a way that I don't, I'd recommend going straight into your TV and then down to your AVR; you aren't losing out on Lossless audio because your ATV doesn't do that. You get Dolby Vision that way. And you solve the problem with the sluggish GUI.
Hope this helps.
