Right, like I said, 4k120hz is a very limited market. However, for those of us with living room OLEDs, 4k120hz would be very much appreciated. The couch gaming experience on a 77 inch 4k120hz oled is pretty wicked.

They’re becoming more common though. The Sony oled I just got does 4k120. I’m bummed it doesn’t have hdmi 2.1 though. VRR would have been nice but maybe the hardware is powerful enough it won’t need it.

Fair enough. The displayport has limited use though, given how there aren't many (any?) large 4k120hz televisions with displayport. And let me be clear, that's no dig against displayport (which is the better standard). As far as I know, certain shady license deals keep hdmi artificially ubiquitous on televisions.

Eh, that's not really how it works. It all comes down to the HDMI standard. The HDMI 2.0 used by the steam box has a max officially supported output of 4k60hz. You need HDMI 2.1 to get 4k 120hz - regardless of the capability of your machine.
