Series X 4K Display Issues on Vizio TV- but only one HDMI input

Hi Scrappy,

Okay so looks like your TV supports 4k, HDR and 120Hz, so thats a good start atleast.

I've tried looking all over, and seen alot of other threads with similar issues with the Vizio TV's though.

Here's a post from 3 years ago, with a person with a very similar (not exactly the same) issue to yours (No real fix found)

Xbox One X not working in 4k on Vizio TVs

But there are some trouble shooting guides you might be able to look through that might help.

Trouble shooting 4k and HDR on Xbox One

4K on xbox

What I'd maybe suggest, is changing the advanced settings to ensure all settings such as 60Hz and 4K are setup.

Also on your TV, follow these steps.

1. Make sure you are using HDMI port 1 or 2
   
2. Make sure you are using a high speed 2.0 HDMI cable
   
3. Go to MENU>INPUT SETTINGS>CHOOSE HDMI PORT>OK>TURN UHD ON
   

What is the model of your TV? Sometimes, manufacturers disable 4K resolution over one or more of the HDMI inputs, and you must manually enable it in the TV's settings with your remote.

The Xbox One can support almost any TV with an HDMI input. The 8/10-bits on panels only indicates whether the TV supports HDR or not, which is an optional feature. The Xbox One X can support 8-bit 4K displays (considered non-HDR
4K).

If your TV is an 8-bit panel (non-HDR), then make sure the "Color depth" setting is set to "24 bits per pixel (8-bit)" while switching to 4K UHD resolution. You may also want to experiment with the advanced video settings if you
are still having issues in trying to get your Xbox One X to display in 4K.

My TV, Vizio V655-G9, says in the manual it supports 4K UHD @ 60hz. However, my Xbox One S says my TV does not support 4K @ 60hz. So I can select 4K resolution in settings.

Everything is updated and I have tried many different ports and many different HDMI cables. Advanced settings is on Auto-Detect.

Hey so i ran into this issues with my older vizio as well. So you need to go into your tv settings or use the vizio smart cast app on your phone you can download it if you down have it and connect your tv to your phone but you need to go to your input settings
and select the hdmi port your xbox is connected to and turn on full UHD Color this allows the 4k image go back to your xbox tv and display options and check tv details if there not showing up sometimes restarting the xbox is necessary

Whats the brand and model of the TV? I have a Vizio P55-c1 and Im able to view 4k content via xbox netflix app. also which input is the One S connected to? Some 4K Tvs only have 1 input available to allow 4k

I thought I did, but I switched from a non 4k game to Red Dead 2 and I get the loud beep from my tv, screen goes black for a second like the display goes off like the display is off, then it comes back and has the input information at the top of the screen.
TV is a Vizio E60 if that helps any, and I am in HDMI 1.
