120hz 4k HDR Tv for PC very hard to find

[86kotek]

Hi sorry for dumb question but it seems that tv manufactures hidden refresh rate of their tvs lately. As in title Im looking for 120hz 4k HDR Tv for my PC but i cant find any. Iremember couple yars ago it was an easily accesible information now I cant find straight forward answer.

My current TV is 60hz but I am very annoyed with stutter i get below 60FPS with vsync on and screen tearing above 60FPS with vsync off.
I dont really want a monitor and i guess it will be some time before nVidia BFGD will be released.
Any help would be kindly appreciated

Dell is releasing one this year, although it might technically be a display, not a tv.

The problem with TV manufacturers is that there's been little reason to justify the cost of adding Displayport to existing TVs, which are capable of 120hz internally (used for Motion Interpolation). HDMI 2.0b is limited to 4k/60Hz HDR, so the bottleneck is in the interface with the outside world. 4k/120Hz/HDR won't happen over HDMI until we see version 2.1 interfaces on displays and TVs. See here:

https://en.wikipedia.org/wiki/HDMI#Refresh_frequency_limits_for_HDR10_video

You'll notice that the 4k/120Hz monitor by Asus PG27UQ has Displayport 1.4, which is needed for the high bandwidth that 4k/120Hz demands. See here:

So, you can wait a bit longer, or you can get a 4k TV that will accept a 1080p HDR signal at 120 Hz, like the Sony A9F. I'm still a bit fuzzy myself when it comes to HDR and whether 4:4:4 chroma means HDR, but I believe it will work. So, if you don't want to wait any longer, check Rtings reviews. Go to this page:

You'll want to click on each manufacturer's "Lineup" like this one for Sony:

Now, look at the listings. Be sure to ignore the ones with less than 120 Hz Native Refresh Rate. But you can't stop there. You have to read the details of the review. Let's look at the review for the Sony A9F:

Rtings entire review is very thorough and you should read all of it, but what you're looking for initially is the "Inputs" section:

https://www.rtings.com/tv/reviews/sony/a9f#comparison_1799

Focus on "Supported Resolutions" and look for the 120Hz video modes that are supported. In this case, the A9F natively supports 1080p @ 120Hz, but don't forget to read the notes just below. Some TVs will take 1080p/120Hz, but they will not display 4:4:4 color properly. The A9F is reported to have no color problems in this mode:

The A9F supports all common resolutions without issue, including 1080p @ 120 Hz, which had to be forced on all previous Sony TVs. It displays 4:4:4 color perfectly, as long as either the 'Game' or 'Graphics' Picture Mode is used.

Many of the Samsungs will accept 1440p at 120Hz, but don't display 4:4:4 color properly.

Also, check out the Wasabe Mango, but that seems to be a riskier option.

As he stated above right now there are NO TVs on the market that support 4k @120fps. So that is why it's hard to find.

At the CES that just passed they announced a few TVs that will offer 4k at over 60fps thanks to HDMI 2.1.

I realised my asumption came from that last time i was looking into PC displays, 4k was not even available and a lot of TVs were in fact 120hz but FullHD.
