Can only operate independently, not designed for HDMI connection.
14 January 2022 
In 4 days of interacting with this TV, I've found 2 critical and obvious bugs:

1. When supplying standard video 24 frames/sec to any HDMI from any source, there appears a monstrous input lag and very noticeable judder (shaking and frame skipping) - a regular film, regardless of resolution, turns into a random slideshow (including in HDR). It doesn't matter what the signal source is. The only solution is forcibly switching the HDMI mode to "PC", but in this mode, image settings are entirely unavailable, you cannot select Filmmaker Mode or Cinema mode, and watching a film in such conditions is eye-straining. There's no such issue with video at 30 frames/sec or 60 frames/sec, but the vast majority of film content is at 23.976 frames/sec, making it unwatchable from external HDMI inputs. All sharpness settings have been tried 800 times with different variations - all in vain. So a Bluray film with a home theater can only be watched either in slow slideshow mode or in "eye-watering" mode. I haven't noticed such problems with playback through the TV's built-in means, but...

2. The HDMI-eARC setting is broken. More precisely, enabling it completely disables audio passthrough to the home theater via the return channel. It doesn't matter what audio codec is in the video content, the TV tries to send DTHD to the home theater, which collapses after 2-3 seconds and switches to lousy PCM. If you don't touch eARC, then in regular ARC it correctly passes DD and DD+. In addition to Samsung's refusal from DTS, this is a monstrous blow to home cinema enthusiasts.
Works great on its own
Can only work on its own, not intended for connecting external devices via HDMI. Do not buy under any circumstances if you have a home theater, Blu-ray player, or set-top box (Android, satellite, cable, no matter which one)! Unfortunately, I don't have a gaming console to test movie playback on it.
