Which Tv’s support native 120hz @1440p or 4k?

From what I understand most tv’s don’t support native 120hz. However, I heard the newest LG Oleds will support 4k 120hz. Any others that support 120hz? I don’t think any graphics cards can push 4k 120hz yet, so 1440p 120hz would work.

The new LG OLED's support most of HDMI 2.1, so yes they can handle 4K @ 120Hz. However, any HDMI 2.0 TV is capable (bandwidth wise) of 1440p @ 120Hz. That said, I'm not sure what TV's support 1440p. I just checked the specs of my Sony Z9F, and it does not appear to support any 1440p resolution. Since I do not use a PC attached to it, I don't really care. What else outputs at that resolution? My Z9F does, however, support 1080p @ 120Hz, and that's just fine for me when it comes to console gaming.

EDIT: Was curious so did a little Googling. Who knows... maybe my TV can support that but it just isn't listed in the specs. Wouldn't be surprised though if it couldn't. Doesn't matter for my uses. Looks like Samsung models do though, as I saw a long thread about getting the Q6 to run at 1440p @ 120Hz. Looks like it's possible with the FreeSync stuff (of which I know nothing about). Samsung's seem like the best to go to for pure gaming use.

According to RTINGS, all of the Samsung QLED sets support 1440p @ 120Hz natively. Even last years Q6FN. All of the Sony sets required forced resolution.

Good Luck failing at 4K @120 Hz even the best Graphics cards can’t deliver 120Hz at 4K the best thing to have is FreeSync and Gsync which allow for variable on the fly adaptable variations delivering smooth silky motion. I won’t buy a TV without FreeSync or HDMI 2.1 Next year. This year I need a new TV and I am gonna give the Hisense H9F a shot since it has every feature.

Will the h9f support 1440p @120 hz?

According to RTINGS, q70. q80 and q90 can't do 120 Hz in game mode because of frame skipping.

There are many different games with different HW requirements out there. Also, nobody forces you to run everything at ultra. 120 fps @ 4k is doable even without a top tier GPU.

Correct me if I am wrong but I don't think there is a GPU out there yet that is hdmi 2.1 compliant which is to say able to handle 4k 120fps bandwidth. Yes, technically 4k 120fps 420 8bit can be achieved with hdmi 2.0 but who would want to play with those settings? An adapter between displayport and hdmi 2.1(2019 oled tv) are not available yet and usually these adaptors have their own issues.
I currently own a 1080ti and play all my games on a vizio pq65 1080p at 120fps either 444 8 bit rgb or 422 ycb... 10 bit with hdr. I will upgrade my video card,r eceiver and tv when 4k 120fps can be handled by 1 video card and of course are all hdmi 2.1 compliant with vrr, ect...

Yes, that's true. First HDMI 2.1 GPU - Navi - will probably start selling in 3 months. Tbh tv's should just include displayport, HDMI seems to be always trailing behind.

If the concern is input lag, you really don't need game mode if you're playing at 120hz on those TVs. The input lag in movie mode is less than 20ms.

Note: When the TV was set to 'PC mode' or 'Game Mode' and we sent a 120Hz signal, the TV skipped every second frame. So in order to measure the input lag of a proper 120Hz video, we set the TV to 'Movie' mode.

But the lag could be less than 10 ms (Q60). That's big enough difference when you're doing aim heavy shooting, for instance. Although that movie mode with its better processing could be better suited for everything else except FPS games.
