Itsellä oli sama ongelma Samsung UE55MU6195U + PS4 pro kanssa ja tämä ohje auttoi ainakin itselläni - oletko tätä kokeillut?
PS4 pro&Samsung TV - Black screen problem
Just follow these steps and you’ll be good
Step 1
Turn ON your TV, go to Settings > General > External Device Manager > HDMI UHD Color > Deactivate it for every HDMI port.
Step 2
Turn ON your PS4 Pro, go to Settings > Sound and screen > Video Output Settings > Leave everything on Automatic except for HDR and Deep Color, turn those OFF because you won't be able to turn them on as your HDMI UHD Color is off rendering the TV incapable of using HDR/Deep Color, so OFF. You will notice the PS4 Pro will go into YUV420 Automatically with no support for HDR.
Step 3
Follow step 1 (this time the TV will be ON, obviously), then activate HDMI UHD Color for the port you are using with the PS4 Pro. The TV will go black for few seconds, then will display an image again, same as the Black screen dropout we get. Then notice the PS4 Pro will change from YUV420 to RGB because it was in Automatic, then you will leave everything Automatic this time, including HDR and Deep Color.
Once you have done the steps above try to switch resolution from Automatic to YUV420 and back again to Automatic in your PS4. This helps to make it stable with no blackouts whatsoever.
