Xbox Series S HDMI Not Working / Black Screen: Fix Guide

A black screen or "No Signal" on an Xbox Series S is almost always a cable, input, or display-setting issue — not a dead console. One Series-S-specific thing to know up front: the display reset uses the Pair button, because the Series S is digital-only and has no disc drive or Eject button (the X's reset combo uses Eject — that step doesn't apply here).

Fix it

1. Confirm the input and reseat. Select the exact HDMI the Series S is on, and reseat the cable at both ends — a half-seated connector is a classic black screen.
2. Power-cycle the console fully. Hold the Xbox power button ~10 seconds until it shuts off, unplug for at least 30 seconds, then restart — clears a hung video state.
3. Swap the HDMI cable. Use the included or a certified cable into a known-good port. A marginal cable can blank at 4K/HDR.
4. Try another HDMI port / another TV. If one input is dead but another works, that port failed; if it's black on every TV, it's the console's video output or settings.

The Series S display reset (low-power video reset)

If the screen is black before you can reach settings, force a safe video mode:

1. Fully power off the Series S (hold power 10 seconds), then unplug power.
2. Hold the Pair button AND the power button together, keep holding Pair as it boots. The Pair button is the small circular one on the front of the console, beside the USB port — the Series S has no disc tray, so it's the only button down there — this starts the console in low-resolution (640×480) troubleshooting mode, which most TVs can display.
3. Once you see the picture, go to Settings > General > TV & display options and set a resolution your TV supports (then raise it).

Note: the Series S has no Eject button, so ignore any guide that says "hold Eject" — that's the Series X black-screen reset. Use Pair + Power.

If it boots but the screen stays black at 4K

That's a resolution/format mismatch:

• In low-res mode, set Resolution to your TV's max and run 4K TV details to confirm what the link supports.
• The Series S outputs 4K (and renders games at up to 1440p), so it needs a TV input that accepts 4K — enable the TV's enhanced HDMI mode (Input Signal Plus / Deep Color / Enhanced). If it shows a picture but drops 4K, HDR, or 120Hz, that's a format-handshake issue rather than a black screen.

FAQ

My Xbox Series S has a black screen. Reseat the cable, power-cycle (hold power 10s, unplug 30s+), and try another port. If still black, do the display reset with the Pair button.

How do I reset the display on a Series S? Power off, then hold the Pair button + Power together and keep holding Pair for about ten seconds as it boots — it starts in low-resolution mode so the TV can show a picture. The Series S has no Eject button.

It works at 1080p but black at 4K. Enable the TV input's enhanced HDMI mode and use a certified cable. The Series S outputs 4K and needs a port that accepts it.

Does the Series S play 4K? It outputs 4K (UI and video apps) and renders games at up to 1440p — it needs a 4K-capable HDMI input, which is why the enhanced mode matters.
