Troubleshooting with Xbox One X 4k resolution

What is happening is your Xbox one x is programmed to run off of 4k 2160p or 1080p . If your on auto detect 1440p will see if its compatible at that particular refresh rate. If it cannot use it at that setting it will drop to the 1080p setting. Here's some
information on the resolutions the Xbox x has available and some trouble shooting to see if you can get it to display.

Troubleshooting Resolutions

I think I had the same exact issue as you with my 65" Samsung TV (although my model is the UN65KU6290FXZA). So it appears the Xbox One X defaults to 1080p on initial setup. My settings backup on my external HDD did not transfer display settings. My TV shows
all green checkmarks in the "4K TV Details" page, though. After some fiddling with both the Xbox and TV settings, I did manage to get it running on 4K+HDR normally now. I am assuming your Samsung TV has almost the same UI as mine.

While I am unsure of how exactly I fixed it, my own troubleshooting process seemed to work itself out. I remember it well because I literally did it all a few hours ago before this post. The bolded parts may be the important bits that helped solve my problem.

• While the Xbox was on, I disabled UHD color in the TV settings: Settings > Picture > Expert Settings >HDMI UHD Color > Set HDMI 1 to "Off" (Xbox is connected to HDMI 1)
• Performed a power cycle on the console.
• Turned the TV off and on (Xbox still off).
• Set HDMI 1 back to "on" for UHD color. (Xbox still off).
• Turned Xbox back on, let it boot up normally, and get back into the display settings.
• Set color depth to "30 bits per pixel (10-bit)", left color space to "Standard".
• Set TV resolution to 4K UHD... works now! Weird.
• I noticed as I ran the 4K-enabled games with HDR, the output goes blank and the TV thinks there's nothing connected.
• My Xbox was not broken though, I could still tap the Xbox Guide button, and press "A" to get back to the home screen like normal.
• Seemed like an HDR issue, so I looked into the Advanced Video Settings in the Xbox.
• I left everything checked except "Allow YCC 4:2:2". ("Allow 3D" is greyed out as my TV does not support 3D).
• Now, I could play any 4K+HDR game. I was successfully able to play the Star Wars Battlefront II trial on EA Access for a few hours without a hitch.

Sorry if this was all lengthy, but this might hopefully help you since we both have a Samsung TV and we're both setting up the Xbox One X.

Hello Spoons,

We suggest that the following troubleshooting 4K and HDR on Xbox One X and Xbox One S support article is
followed considering that the console is more than likely setup for 4K resolutions as you mentioned switching from a non 4K Xbox One title to Red Dead Redemption 2.

Try following this and let us know if this works.

Best wishes!

The HDMI IN on the XBOX ONE / ONE S / ONE X are all just 1080P there is no 4K pass through on those consoles.

The Xbox One S Supports 4K Bluray and 4K screen resolution - not 4K gaming

The Xbox One X Supports 4K Gaming, 4K Bluray and 4K screen resolution

- Game developer has to make the game 4K

- 4K pass-through is a hardware feature that does not exist within the console. You'd be better

off running your 4k Sky Q into the TV directly. (the xbox is doing what it's designed to do)
