If Control Center is unable to control your PS4, use the PS4 controller to confirm that the HDMI Device Link is activated on PS4 (Settings> System> Check HDMI Device Link).
If this is the first time you are setting up your PS4, you will need to manually press the power button on the PS4 device.
If you have previously setup up PS4 to work with Control Center but are now unable to control it, try using your PS4 controller to make sure the PS4 is not locked up.
- Use the Control Center remote to go to Settings> Devices> Sony PS4> Control Settings> Change Control type.
- Restart the PS4
If none of these options allow Control Center to control the PS4, try using a different HDMI 2.0 cable between PS4 & Control Center.
