I bought this at-risk not knowing if Linux would work smoothly on it without driver hassles.  I was pleasantly surprised that all hardware works great under Arch Linux 2020.07.01-x86_64 without hassle, including sound-over-HDMI (which has been a problem for other vendor's models) via ALSA + Pulseaudio.  My TV can now be used as a full-fledged Linux PC, and also a 24/7 always-on dnsmasq server for home LAN.
