A green screen (or a green tint over everything) looks like your PS5 has died. It almost never has. What you're seeing is the console and your TV failing to agree on the video signal — a botched HDMI handshake — and the giveaway is when it happens: most people get the green screen right after the PS5 wakes from Rest Mode, where it doesn't cleanly re-negotiate the connection. So before you panic, force a fresh handshake.
The quick fix
- Power off fully and reseat. Hold the power button until it beeps twice and shuts all the way down, unplug for at least 30 seconds, then firmly reconnect both ends of the HDMI cable and power back on. That alone re-runs the handshake from scratch and clears most green screens. (If you get no picture at all rather than a green tint, work through a PS5 HDMI no-signal instead.)
- If you can see the menu, fix RGB Range. Go to Settings > Screen and Video > Video Output > RGB Range. It defaults to Automatic; set it to Limited (the right match for most TVs) and test. A mismatch here is the classic cause of a green or purple tint.
- Turn HDR off to test. In the same Screen and Video > Video Output menu, set HDR to Off and check Deep Color Output. Plenty of people clear a full green screen just by disabling HDR — it means the high-bandwidth signal was more than the cable or port could carry.
If the screen's too green to navigate
You can fix it blind through Safe Mode. Hold the power button until the second beep to boot into Safe Mode, connect a controller with a USB cable, and choose Change Video Output → Resolution, then drop it (try 1080p or Automatic). If lowering the resolution fixes it, you've confirmed it was a bandwidth/handshake problem all along.
Why it happens (and the part most guides miss)
The Rest Mode connection is the real story here. On wake, the HDMI handshake often isn't re-established, so people blame "the game" or "HDR" when the actual fix is forcing a clean boot — or just turning Rest Mode off if it happens every time (Settings > System > Power Saving > Features Available in Rest Mode). Two things make the handshake more reliable: plugging into your TV's HDMI 2.1 / "4K 120Hz" labeled port, and using a certified Ultra High Speed HDMI cable rated for the PS5's 4K@120Hz output rather than a generic spare. If your TV doesn't have a proper HDMI 2.1 port, that's where stepping up to a TV built for the PS5 Pro pays off.
When it's actually hardware
Here's the clean diagnostic. If dropping the resolution or turning off HDR fixes it, it was a handshake/bandwidth issue — cable, port, or settings. But if green artifacting shows up during gameplay under load and follows the console across different TVs and cables, that points at overheating or a failing GPU, and that's a repair Sony handles, not a settings change.
FAQ
Why does it only happen after Rest Mode? Because the HDMI handshake doesn't always re-negotiate on wake. A full power-off boot fixes it, and disabling Rest Mode prevents it.
Is my console broken? Usually not. A green screen that clears with a reseat, an RGB-range change, or a lower resolution is a signal problem, not dead hardware.
Does the cable really matter? For 4K HDR and especially 4K@120Hz, yes. A cable that can't hold that bandwidth drops the handshake — a certified Ultra High Speed cable rules it out.
