Any real 4k 120hz TVs?

I was hoping to find a 4k 120hz TV during the holidays sales this year but I'm not sure if any actually exist. They say things like "effective rate 120" or "motion rate 120". Are there any 4k TVs out that will actually do 120hz in 4k with a PC right now? I realize only the new GeForce 2000 series can do this.

Any modern GPU can output 2160p 120Hz.

As far as I know all the TVs so far are 60Hz only at 2160p and what they often call 120 etc. is motion interpolation as in processing done in software inside the TV, you can do this processing in your video player instead at higher quality probably since TV doesn't have the compute power for much unlike modern GPUs.

Is you best bet to see at least somewhat is out there out of the endless pile of TVs one like the other.

Only the newest GPUs with HDMI 2.1 can do 4k 120hz, over HDMI at least and no TV's have display port.

Wasabi Mango has one, but the only video I've seen of it in action is here:
Just found this video on it which makes it look a lot better:

oh really so a 1080 Ti can do 4k at 120hz?

is the mango literally the only one?

Currently I can't find any 120hz @4k TVs or monitor on newegg.

No but lots of TV's with 1080p 120hz, which is fine if you are sitting couch distance away. Problem is no gsync (yet) so just play games you can max 120 fps at all times.

Is the purpose to achieve some benefit while watching actual TV, or just to use as a dual purpose TV/computer monitor? I think all TVs are using fake "soap opera" mode which makes me gouge my eyes out except for maybe one or two models mentioned.

I would like to be able to game at 4k 120hz on my pc. I don't care about the rest.

The panels are 4k pixels and are 120hz refresh rate capable, they have been for a while.
The issue is not the panels but the connectors into the TV/Monitor. TVs do not come with DisplayPort, supposedly because of DRM reasons from what someone in the industry told me. TVs only come with HDMI, and no TV has an HDMI port capable of 120hz in 4k resolution. If they came with a DP1.4 input then they would be able to do it, but such a thing doesnt really exist. Only a handful of computer monitors have that sort of connection. The Wasabi Mango model mentioned in this thread is one, as are the new $2000 Asus and Acer model GSync monitors. They are not TVs however, they are just computer monitors. No actual TV has a 120Hz capable HDMI port.

Thanks for clearing that up. Can we expect to see 120hz TVs anytime soon? When will TV's use HDMI 2.0/2.1?

I don't think Displayport aren't put on TV's for any other reason than 99% of the time they would go unused. That extra cost is hard for TV manufacturers to justify. On some of the original Panasonic 4K TV's around 4-5 years ago, they did have a Displayport.

I think people voted with their wallets on that one. I picked one of those Panasonics with DP up in 2014 for 4k gaming with sli 780tis. The DP works great. But apparently not enough people game on these for Nvidia to recognize the tv has functional hdmi 2.0. My 1080tis will only put out 1.4 over the 2.0 port, but an active dp to hdmi adapter will go full 2.0 into that hdmi port and intel gemini lake does as well. Can't blame Nvidia for not paying attention to a nearly nonexistent hardware segment. I've heard that most of the older 4k monitors didn't do real 4:4:4 over hdmi and mine doesn't match that since it does. It also runs signal processing through a chip made by a company sold in 2017 for $20 million, so that might have something to do with support.

If nobody buys them when someone makes them, nobody will make them.

I bought a TCL 6 series 55" back in July. It is a 60Hz panel, but I've honestly been shocked at how well their interpolation works. It doesn't look unnatural like some of the Samsung's and LG's that I've seen. I actually like it so much, that I plan on buying another smaller one for the upstairs. It was something I was really worried about going into (I was replacing my 7 year old true 120hz Olevia TV) since I knew that it wasn't a true 120hz. Even in game mode it still looks good though, I wouldn't be to worried honestly. Also, I didn't get the hype with HDR before, but now I do.

Many of the 2018 4k Samsungs will do 1440p/120Hz, but you will lose HDR/4:4:4 (BTW, are they the same thing?). Check the "Inputs" section of the individual model reviews to verify:

https://www.rtings.com/tv/reviews/samsung

There's at least one Sony 4k TV that also does 1440p/120Hz, I think.

My LG C7 4k TV advertises 1080p/120Hz, but again HDR is not possible in this mode. I can still feed it 1440p/120Hz even though it's not advertised as supported and it looks a bit smoother (less jaggies) that way, probably because basically my gpu is oversampling at 1440 and the tv is scaling it to 1080. I can see the dithering and a bit of banding and I'm somewhat disappointed to see the detail of 4k res and better color go away, but I'm hooked on the high FPS smoothness now. I haven't seen any comments on how good the image quality on the Samsungs is at 1440p, but they are newer tech than my C7 so maybe it's better?

So, if you are willing to settle for 1440p/120Hz without HDR/4:4:4 then go for one of those TVs that supports it.
