I have a Playstation 4 Pro and encountered a super annoying problem when connecting it to my Samsung QLED TV: It when I would switch it on, the screen would constantly flicker – it gained and lost signal very rapidly.
After searching around a while on the net I discovered the issue was related to the video setting of the Playstation 4 Pro when it’s connected to some 4K monitors.
To resolve this issue:
- Go to your main PS4 desktop
- Go to Settings > Sound and Screen > Video Output Settings
- Set Resolution to “2160p – YUV420”
The screen should now be fine.
