Q: How to fix it out when the screen flickers or become black?
A: HDMI SPLITTER may be not compatible with PS4 because some famous brand like Sony, Panasonic, Nintendos have their own Protection protocol. So you need to try to plug in and plug out the HDMI cable or change the other port to ensure the stability.

Q: If the PS4 Pro connect to the HDMI SPLITTER, no screen shows, how to fix it?
A: Firstly: Keep the TV'S resolution rate same with PS4 Pro's resolution rate.
Secondly: Ensure you have used the HDMI 2.0 Cable.
Thirdly: If the PS4 Pro has set up the HDR function, you have to check whether the monitor or TV supports HDR function. Otherwise, please shut up the monitor or TV'S HDR.
