Back out by pressing B and go to Video modes. Again, this screen is very important for verifying what kind of visual fidelity you’re getting. The basic rule: tick every box. If your display doesn’t support one of these specs, it’ll be greyed out like in our example. If you untick Allow 4K or Allow HDR10, those will stop working, so make sure they’re checked.
Since our display uses HDMI 2.0 and not the Xbox One X’s native HDMI 2.1, features that are specific to HDMI 2.1 are greyed out. That includes variable refresh rate and auto low latency mode. Our display also doesn’t support 3D, which is very rare these days anyway. Make sure Allow YCC 4:2:2 is ticked. That will help a lot of content such as Blu-rays and streaming apps display 4K HDR properly without unnecessary compression. If you untick this one, the Xbox One X will force everything to use 4:4:4 chroma sampling, which is fine for gaming, but not ideal for movies and TV content. Allowing the alternate 4:2:2 chroma subsampling improves image quality in content mastered at 4:2:0 or 4:2:2. Furthermore, for streaming apps like Netflix and Prime Video, if the console tries to impose 4:4:4 sampling, bandwidth consumption could increase. Richer colors require more data, and streaming is optimized for 4:2:0. Forcibly upconverting that to 4:4:4 exponentially increases bandwidth demands and could introduce buffering or outright pixelation.
