The HDMI Forum, responsible for the HDMI specification, continues to stonewall open source. Valve’s Steam Machine theoretically supports HDMI 2.1, but the mini-PC is software-limited to HDMI 2.0. As a result, more than 60 frames per second at 4K resolution are only possible with limitations.
Nor do you get TV tuners. While most geeks probably couldn’t care less, any associated family do prefer to watch Great British Bake-off as it airs.
My country just disabled radio and tv over coax wire and provider send ip-TV boxes.
This allows to have now faster internet, which I like.
I would use an Apple TV or a Chromecast in that case. Most TV providers that I know offer their own mediabox anyway, so no need for TV Tuners anymore.
You could get an external digital tuners and a hdmi switch to switch between pc and the TV.
My grandmother still has an ancient tv with one of those tuner boxes she bought for her tv when analog went off the air.
