Troubleshooting tips

FAQ

Does Xbox Series X support native 4K?

Absolutely. Many games run at native 4K, while others use dynamic resolution or upscaling depending on performance needs.

Use the Ultra High Speed HDMI 2.1 cable included with your Xbox Series X for the best performance and compatibility.

What’s the difference between 4K UHD and HDR?

4K UHD refers to resolution, while HDR (High Dynamic Range) enhances contrast and color. You can enable both in your Xbox settings if your TV supports them.
