I'm looking for a 4K TV that can display 1080p @ 120hz. I know many TVs claim to be 120hz and up, but only do 1080p and higher @ 60hz. I'd love to get a TV that can display 4K @ 120hz, but I doubt they're on the market yet.

A) Can anyone point me in the direction of a good 4K TV that can display 1080p @ 120hz? (or 144hz)

B) How long do you think it might take for a TV that can display 4K @ 120hz to come to market?
 
That's just not a claim, it's a fact. But the problem is that internally they do 120/240 Hz or what have you, without any interpolation. But externally they only accept a 60 Hz signal. There aren't any 4k TV's that I know of, and even then you'd have to hack it to make it display a blurry 1080 120 Hz picture, because it's not officially in the HDMI 1.4 spec, that's HDMI 2.0. However, even if the TV has got HDMI 2.0, it's still not going to work, because technically you'll be limited to the TV's 60 Hz max refresh rate. You can overclock a display, but when it comes to TV's it's just never recommended. You don't want to mess with a TV, they are very different when compared to a monitor.

My TV's not blurry at 120hz @ 1080p. Didn't have to hack anything, just edit my EDID so my GPU saw 120hz as an option. 4k is 4x the size of 1080p, so 4k@30hz is the same bandwidth as 1080p@120hz.

My TV is rare though, most don't and only accept 60hz as said and do their motion thingy.

HDMI 2.0 can't even do 4k at 120, it's only spec'd for 60hz.

You'll need displayport for 120hz@4k, and TV's don't usually have displayport.
 
Interesting, what model are you using? I've heard rumors about this working, but never am I going to purchase something to test this. I just rely on the internet. :p

^Edit, mainly because how did you get a 60 Hz panel do 120 Hz without overclocking it, or is that what you did?

HDMI 2.0 can do 1920x1080 at 120 Hz. Thank you for clarifying. :)
 
Do you know the pixel clock of your HDMI 1.4? Because in the past, this wasn't possible. And I may have been giving someone wrong information today here on forums actually. What I mean by the past is that... There was a time when the pixel clocks were slow, and wouldn't allow projectors to frame pack 1920x1080 60 for each eye/120Hz.

Supposedly, this review I found is of a TV that does true 1080p @ 120hz. Should I trust this?

Yeah it does say judder-free 24p. So then that TV will display 1080p @ 120hz natively without up-scaling? And without needing to be overclocked?
 
It is LIKELY going to do 120 Hz natively. Do note that there are 24p modes on 60 Hz panels also. Here's the problem with TV/display specs. The manufacturers don't want us to know these things, all they want you to know is how great a display looks, because it's got a 1080p sticker slapped on top of it. That's it, they don't care about the consumers one bit. Instead you'll have to look into this a lot deeper, do your own research. And I'm not saying this to make you feel bad, it's just the reality of the display market.

I'm doing the best I can to dig having already spent 10+ hours, but I'm not finding much legit info on these TVs. Let's say I bring one of these TVs home, connect it to my PC and go to: Control Panel -> Appearance and Personalization -> Display -> Screen Resolution -> advanced settings -> Monitor and check "Screen refresh rate", will that tell me for sure if it's a 120hz panel?
