Thanks for trying to help. The PS4 is fine, tried different cables. Checked everything seems to be up to date. Maybe its a problem with the port or something I'm gonna have to keep looking.
I use my Alienware laptop as a screen for my PS4 using the HDMI port. Lately it no longer shows picture just black with sound still working. Could a driver update fix this or could it be a problem with the input itself? Cable is working fine.
