Hello there,

I recently bought a simple Chinese projector with ATV onboard — and though being a budgety little device, it is marketed as one with HDR10 support.

I tested it with 4K HDR on some other apps and everything seems OK: AVC requires quite some buffering but still works, HEVC just goes butter smooth straight away.

But when I launch a YouTube HDR video, the picture just freezes no matter the resolution. The app itself keeps running with audio coming in, so I have some doubts it's all about the hardware.

What I know for sure, it's not about bandwidth. The projector is connected to a 5 gHz Wi-Fi network, the only other device using it is my MacBook. Other apps easily run streamed video with up to 50 Mbps bitrate, including 4K HDR already mentioned.

Would be happy to hear any ideas or suggestions
