What cable do I need to connect an Xbox Series X to a TV?

An Ultra High Speed HDMI cable, which comes in the box. If it doesn't reach, a longer Ultra High Speed (HDMI 2.1) cable keeps 4K at 120Hz.

Checked 10th November 2026.

How to connect it

  1. Plug the cable into the Xbox's HDMI out socket (not HDMI in).
  2. Plug the other end into the TV's HDMI 2.1 socket if it has one.
  3. On the Xbox, go to Settings, General, TV and display options, and set the refresh rate to 120Hz.

Worth knowing

  • The Xbox Series S outputs up to 1440p, so a standard High Speed HDMI cable is enough for it.
