Yeah I've been thinking what a missed opportunity with consoles coming out to take advantage of it. PCs now probably could too.
Theres some that probably are 4K and 120Hz+ already, but theres nothing out right now that is HDMI 2.1, so 4K AND 120Hz simultaneously isn't an option. You could argue almost nothing could reach that, but with DLSS and consoles with checkerboarding.. possible we will see it.
The only one I've seen with HDMI 2.1 upcoming is some ASUS ROG monitor and it suspected to be around ÂŁ3k... which is ridiculous, it seems the Mini LED is what is justifying the price, which also means more local dimmin zones, but seems that doesn't even fully eliminate the halo effect, so wonder if it's worth it.
I'm going for the EVE Spectrum when it eventually releases, which will have HDMI 2.1, 4K, 120Hz, only issue I have with it is it only has DisplayHDR600 and like 12 local dimming zones?
I do have a monitor with 1000 nits now and more dimming zone and it already slightly bothers me, but got used to it over time. I may just try the global dimming option instead on Spectrum if it bothers me enough.
For me and I imagine many people though, where I game there is no room for a 40"+ TV, so monitors are literally the only choice, maybe it is niche but feels to be growing one at least with people I know, definitely feels monitor companies have lagged behind TVs for a while though. Not as good HDR (also Windows fault as a platform with how they handle it too), and they're priced crazy in comparison to similar TVs.
