My Xbox Series S doesn't show video on 4k TVs

JoãoGustavo5 · May 21, 2025

I recently bought an Xbox Series S, but I'm having trouble getting it to work with 4K TVs. The console simply shows "no signal" on any 4K TV I try.

Here are the details:

It works normally on 1080p and 720p TVs.

When I leave the resolution setting on "auto-detect", the Xbox always sets it to 640p, regardless of the TV's resolution.

Tested on a Samsung 58TU7000 4K TV: it says "no signal" and doesn't show anything on the screen.

I used the Xbox app to mirror the screen and saw that the console booted up in 640p, but the TV still showed "no signal".

Also tested on a LG OLED 4K TV: same issue, no signal.

The only 4K TV that displayed an image was a SEMP Roku TV, and even then, only when I manually set the HDMI mode to “2K”.

Still, the Xbox video settings showed that 4K was not supported.

I'm using the original HDMI cable.

The console is out of warranty.

I’ve already tried resetting the TV, switching HDMI ports, and nothing worked. Has anyone been through this?

Hi,

and did you set your resolution to 4K in the general settings of the console ?

There it shows also a list of what my TV shows and what it can't. Like for example it can't show 4K with 120Hz, only 4K with 60Hz.

If I start a game with 4K support the Series S is switching to 4K. A game like Rocket League for example.

l you likely have a damaged HDMI port that will have to be repaired or the system replaced

I hope not, but if nothing works, I'll take it to technical support.

In the options, it does not allow you to select the 4k option, and in the HDMI resolution it only goes up to 2K. And in the list everything appears with either an X or an alert, no option is green, but I have never tried to start a game with the TV showing no signal, I will test it.

I am having a similar issue. My xbox one s and tv support all video functions, and when gaming or in the menus, my tv shows that the output is in 4k. As soon as I load up Deadpool 4k blu-ray, my tv shows that the output is 1080p.. Any ideas?

Thanks.
