A loose cable can cause “no signal” errors more often than any other problem. If they do seem well secured, unplug, and plug them in again just to be sure. Monitors with multiple input options need you to manually select which cable or HDMI port you’re using, like HDMI 1, HDMI 2, DisplayPort, and so on. Use the buttons on your monitor to cycle through the channels and select the correct input from your PC. If you are using an adapter to switch from one type of input to another, this may be causing issues with the other monitor. Try to remove the adapter if possible, or replace it with another adapter to see if this fixes the issue.

Make sure the PS4 is connected to the correct HDMI port. Try unplugging and re-plugging the HDMI cable in again to make sure you have a secure connection. If it's connected to the correct port, you could switch it to another available port and try again. Also make sure your PS4 is up to date in updates and make sure you vents are cleared of dust and it's not in an enclosed cabinet for it to overheat. Simple solutions but that's all I can offer besides suggesting it being serviced again. https://www.partitionwizard.com/partitio...-black-screen.html
