At this time, some owners of PlayStation 4 Pro are reporting some problems with the console, which does not recycle to properly process the video signal, especially on 4K TVs of LG, although the problems could also occur with other brands of panels.
Due to an error of the HDCP protection, after the console connects to the screen it remains completely black, while the audio works correctly. A Reddit user claims to have solved the problem by following the below procedure:
1. Turn off the PS4 Pro using the appropriate button completely.
2. Press and hold the power button for seven seconds until you hear a double beep and at this point you will see the Safe Mode menu.
3. From this concerned menu change your HDCP setting to 1.4, the console will reboot showing images on screen.
4. Now go to the PS4 Pro System menu and turn off the HDCP.
If the screen supports HDR, you must enable it manually, for details refer to the manual of your TV.
