Looking for a help : My xbox series x can't run 4k UHD at 120HZ in my tv ( LG NANO86 )

The LG UHD 4K TVs are really nice and capable of running 4K for the Xbox One X. They are a little more affordable compared to Samsung.

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.

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!

If it's only just for use with the Series X, I would opt for a TV, A 4K true 120Hz TV...

This would be the 4K TV, I would personally go for at a minimum, If pairing with the Xbox Series X...

Amazon.co.uk - LG C1 - 4K - 120Hz TV - There is the newer LG C2 model but it would cost more.

With a 4K monitor, you'd really need to get one that has HDMI 2.1 ports for it to work flawlessly with the Series X, Though that would mean it'll be a 4K 144Hz monitor,

With the Xbox Series X only being able to output a maximum of 120Hz, A 144Hz monitor can be a bit of a waste due to not using the monitor full potential, unless it also being used with a high end 4K high refresh rate gaming PC, never the less it will still give you 4K at 120Hz...

This would be the 4K monitor, I would personally go for at a minimum, If pairing with the Xbox Series X...

Amazon.co.uk - Gigabyte M32U - 4K - 144Hz Monitor

I personally use a LG 27GP950 4K 144Hz monitor with the Series X, But i also use it with my high refresh rate 4K gaming PC.

Not knowing your budget, The TV and Monitor i linked, I wouldn't go for anything less personally, without compromising the gaming experience too much.

hi i would like to have 120 fps on my tv with my serie x , i take yu a screenshot of settings tv, i dont understand why in settings xbox they dont proposed 120 fps at 4k but i can play 120 fps at 1080p ?

You won't get 120 fps on that TV, as it's only a 60hz display, 60hz = 60 fps at most

To get up to 120 fps at 4K, you need a TV that supports 120hz and has HDMI 2.1 ports and again your TV only has HDMI 2.0 ports, but most games on the Series X are locked to 60 fps at 4K,

Something like the LG CX is the best TV to get at the moment, and that's a TV that can go 4K at 120hz,

A 60hz display = up to a maximum of 60 fps

A 120hz display = up to a maximum of 120 fps.
