The TL;DR is that the organization that controls the HDMI standard won’t allow any open source implementation of HDMI 2.1.

So the hardware is fully capable of it, but they’ll get in trouble if them officially implement it.

Instead it’s officially HDMI 2 (which maxes out at 4k @ 60Hz), but through a technique called chroma sub-sampling they’ve been able to raise that up to 4k @ 120Hz.

However there are some minor reductions in picture quality because of this, and the whole thing would be much easier if the HDMI forum would be more consumer friendly.

In the meantime, the Steam Machine also has display port as a completely issue free display option.

        Buy monitors instead. Also saves you the headache of dealing with “smart TV” bullshit.

          Hard to find monitors larger than a certain size that aren’t exorbitantly expensive, and I do like a large screen when it comes to Couch Gaming and watching TV (well, streaming video, I ain’t gonna pay for a TV license just to watch the one terrestrial TV show I actually care about)

          Do you know of any big dumb TVs or monitors that I could buy in Europe? I only know of Sceptre TVs which are mostly meant for businesses and storefronts but they are extremely hard to get in Europe.

            Biggest I found is the Acer Nitro XV275KP3 Gaming Monitor. You kinda pay gaming hardware prices, but given the support for up to 120Hz and HDR10, I was OK with that. It’s mostly used for gaming, anyway.
            It used to be that beamers were a way to sidestep the “smart” bullshit, but they started adding that, too. Even the business ones.

              That one is 27". I think that’s way too small for the living room. I also consider 120hz to be overkill for some couch gaming and movies.

              A 27" monitor will not be anywhere near a replacement for 60" TV, I’m afraid.
