I NEED HELP. My xbox can’t run at 4k 120Hz on LG NANO86

To achive 4K at 120hz your TV needs to have HDMI 2.1 ports and supports 120hz, such as the LG CX TV,

The bandwidth limit of HDMI 2.0 will only allow 4K at 60hz.

I had the same issue with my LG Tv but with my Xbox S. The fix for me was to get a HDMI 2.1 lead, the one with the Xbox doesn’t allow the 120hz 4K UHD!

If you go into the Xbox display settings it will tell you what it’s reading from the TV and the compatibility.

If you already have HDMI 2.1 then can’t help sorry!

Please share the exact model, it needs to look like this "LG 27GL850 27'' "LG 27GL850 27"

In the meantime, are you tried to use 4K + 120Hz?
If you try lowering the resolution the 120Hz option appears?

I have a lg 4k tv with hdmi 2.0

That will work fine with Xbox Series X,

However you wont get the 120hz refresh rates at 4K, as that requires to have HDMI 2.1, other than that your TV is fine to use, if your not to bothered about 120hz refresh rates at 4K as an issue for you, there's no need for a new TV.

How do you mean? It's a 165hz monitor can be overclocked to 180hz but to run that you need a pc even to get 165hz due to the consoles cap at the 120hz but it is a lg gp850b ips monitor from LG and it allows me to run 1440p at 120hz but I just wanted to know which would be better for FPS games like Siege etc like if 1440p would have more of an advantage than 1080p as there is a lack of information around regarding that and all I find is things about pc about lower res is better for frames but the consoles are optimised to the best of my knowledge for any resolution up to 4k at 120hz.
