Configure Display Settings & HDR
Your Xbox Series X is a full-capable 4K machine. It runs games at a native 4K resolution with frame rates up to 120 FPS. It has many variations of HDR, too, but if you want to make the most of the Series X’s technical prowess, you’ll need a couple of things.
First and foremost you’ll need to a 4K HDR TV with an HDMI 2.1 port. As long as your display ticks those boxes, you’ll then want to head into the Series X’s Settings menu and go to General and then TV & Display Options.
Here players can tweak the resolution, refresh rate, HDR settings, and generally calibrate your display to provide you with the best possible picture quality.
It only takes a few minutes to adjust these settings if you’re familiar with them. If you’re not, you may want to get someone else to do it for you at some point. A correct set-up makes for a significantly improved image quality.
