PS5 4K 120 Hz Not Working? Fixes to Try in Order

Check the TV and Cable First

1. Connect the PS5 straight to the TV. Don’t run it through a receiver.
2. Plug the cable into an HDMI 2.1 port on the TV.
3. Use the HDMI cable that came with the PS5, or an Ultra High-Speed cable rated for 4K 120 Hz.
4. Update the TV firmware.
5. Check your TV’s settings for 4K 120 Hz.

Sony’s PS5 resolution guide lists these checks. It also says some TVs can have 4K 120 Hz problems while HDMI 2.1 support spreads.

Set the PS5 to Pick the Best Picture Automatically

1. Go to Settings > Screen and Video > Video Output.
2. Select Resolution.
3. Choose Automatic or 2160p.
4. Go back and select Video Transfer Rate.
5. Choose Automatic.

The Automatic resolution setting picks the highest resolution your TV supports. The 2160p setting is 4K.

Stop Screen Flickering

1. Go to Settings > Screen and Video > Video Output.
2. Select Video Transfer Rate.
3. Choose -1.
4. Choose -2 if the screen still flickers.

• ⚠️Trade-off: both -1 and -2 limit 4K 120 Hz.
• 📺Also limited: 4K 50 Hz and 60 Hz with RGB or YUV444 DeepColor.
• 💡PS5 Pro (CFI-7000 only): 8K 60 Hz is limited too.

Fix a Black Border or Cut-Off Edges

1. Go to Settings > Screen and Video > Screen.
2. Select Adjust Display Area.

See What the PS5 Detects

1. Go to Settings > Screen and Video > Video Output.
2. Find Information for the Connected HDMI Device.

That section shows the resolution, VRR, and HDR the TV reports. If it doesn’t list 4K 120 Hz, recheck the port and cable.
