Looks to be LED with HDR. They have other sizes and other models. I am unsure of what model I have.
I use it with Jellyfin via a LineageOS TV box. LineageOS only supports a small subsect of TV boxes so its probably easier to go with a mini PC with a USB air remote + something like KDE Plasma Big screen or Steam Big Picture mode.
I use the wade device for LOS, but they also support a dynalink box, the sabrina model google Chromecast, a few NVIDIA shields, the Nintendo Switch, and a couple radexa devices. Theres also an unofficial image for raspberry pis.
