An Ultra High Speed HDMI cable would be needed to support all the available features on this TV. Hope this helps! Thank you, TCL Customer Support
Sorry, there was a problem. Please try again later.I think it might work for normal TV but it is not hdmi 2.1 so it is possible that features would not work like 4k120hz gaming I would think regular 4k60hz should work I bought some 4$ hdmi 2.1 8k cables myself lol rocketfish seems really expensive - I would do some more research on that cable I'm not sure if it's hdmi 1.4 10gbps hdmi 2.0 18gbps to get 4k120hz you need hdmi 2.1 40gbps
Sorry, there was a problem. Please try again later.Hello, So that cable (unless I’m mistaken) only supports 1080p. If you want 4K you will need to upgrade to a 4K hdmi rated cable. If you want 4K with 120fps for frames and such like with the new Xbox and ps5 you might want to look at the rocket fish 8k hdmi cables. I included pictures of the cable I bought when I got the TV. Hope that helps
