I mean....if this thing actually works well as a TV (does it have a tuner, or just Shield?), and the black levels are at OLED levels, I could maybe justify this in the ~$3k range, considering the refresh rate and the adaptive sync. ...I honestly wonder, though, if they are arguing that GSYNC tax on this is "worth" about $1k.
That 27" Asus is $2k, though, so it does compare favorably well to that....as weird as this sounds. What kind of panel type is this?
I would assume VA since it'd be the one most able to offer these features (and I think that's the main LCD panel type used on higher TV sets), although I might be wrong and a special IPS panel could do it (might explain some of the cost if Nvidia had to commission and actual special production run of panels, although that could be true for non-IPS as well).
I'd guess it'd have a digital tuner (with the Shield providing the base UI and processing), although maybe not since I'm not sure that many people would care (and if you've got the money for this, you probably can buy an external tuner box).
Well when that market has very little competition with adaptive sync at all (think there's some Samsung models that added FreeSync support, but not sure how robust it is, and not sure if anyone else does; I don't recall what FreeSync range the Xbox can support), you can charge a premium, on top of a premium product.
The curious thing would be if a company sees the interest in this and decides to offer a similar product, but one simplified (take out the processing stuff, knowing that people are going to have computer/console that will do that, maybe give it simple "fill" mode where it can just multiply 1080p signal to 4 pixels per but otherwise not process them), give it FreeSync and sell it for substantially less. They could offer budget ones too. A range of 30-50" 4K displays with adapt sync range of 24-72 or 24-90 range for $500 and less should easily be feasible and would get a fair amount of gamers' money. And similar (but higher HDR rating and wider range say 24-120Hz) with 65" panels should be possible for $1000. Sell a separate processing box for people that really need that.
Maybe even try and partner with Sony or Microsoft and offer some more unique features (maybe a 3D mode, maybe the TV can provide more wireless antenna to help boost the console's wifi signal; the console would run the UI and do all the processing - so maybe have it so that the TV functions like an input switch, and then sends the video to the console over HDMI 2.1, and then the console processes it, does any overlays or anything and then sends it back over the same cable; HDMI 2.1 could handle it).
