When your PS5 won't output 4K HDR properly, you're dealing with an HDMI handshake failure between your console and display device. This common issue stems from communication problems in the HDCP (High-bandwidth Digital Content Protection) protocol that secures 4K HDR content.
Quick answer
- Hard reset all devices by unplugging for 60 seconds to clear HDMI handshake cache
- Use a Certified High Speed HDMI cable rated for 4K HDR bandwidth
- Enable Enhanced HDMI mode on your TV's input settings
- Try different HDMI ports on your TV or receiver
Symptoms
- Black screen or "No Signal" message when launching 4K HDR content
- Flickering video or intermittent audio dropouts during gameplay
- PS5 not recognized by TV or AV receiver
- Display automatically switching to lower resolution or standard dynamic range
Quick checks
Test with a different HDMI port on your TV — many TVs only support full 4K HDR on specific ports (usually HDMI 1 or 2).
Lower the PS5's output resolution temporarily by going to Settings → Screen and Video → Video Output → Resolution and selecting 1080p to see if the signal returns.
Step-by-step fix
-
Power down all devices completely. Turn off your PS5, TV, and any AV receiver or soundbar in your setup using their power buttons, not just the remote.
-
Unplug everything from wall power for at least 60 seconds. This clears the HDMI protection handshake cache stored in each device's memory.
-
Check your HDMI cable quality. Ensure you're using a Certified High Speed HDMI cable rated for 18 Gbps or higher. Generic cables often fail at 4K HDR bandwidths.
-
Enable enhanced HDMI on your TV. Navigate to your TV's picture settings and look for "Enhanced HDMI," "Deep Color," "HDMI Ultra HD," or similar option on the specific input port you're using.
-
Configure PS5 video settings. Go to Settings → Screen and Video → Video Output and set:
- Resolution: 4K UHD
- HDR: On When Supported
- Deep Color Output: Automatic
-
Power everything back on in this order: TV first, then AV receiver (if applicable), then PS5 last.
If it still isn't working
Try connecting the PS5 directly to your TV, bypassing any AV receiver or soundbar. Some older receivers don't support full 4K HDR passthrough bandwidth.
Move to HDMI Port 2 or 3 on your TV if the issue persists. Port 1 sometimes has compatibility issues with gaming consoles.
Check for firmware updates on both your PS5 (Settings → System → System Software Update) and your TV through its settings menu.
FAQ
Why does unplugging fix HDMI handshake issues? The HDCP handshake creates cached authentication data that can become corrupted. A full power cycle clears this cache and forces a fresh handshake.
Do all HDMI cables support 4K HDR? No. You need Certified High Speed HDMI cables rated for at least 18 Gbps bandwidth. Standard HDMI cables max out at 10.2 Gbps.
Which TV HDMI ports support full 4K HDR? Most TVs designate HDMI 1 and sometimes HDMI 2 as their full-bandwidth ports. Check your TV manual for "Enhanced" or "Ultra HD" port specifications.
Can a bad HDMI port cause these issues? Yes. HDMI ports can degrade over time or have manufacturing defects that prevent proper 4K HDR signal transmission.
