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.
