When I turn on my ps4, it works. However, the tv shows a black screen. I know that my HDMI cable works because I use it to connect my pc to my monitor. I also know that the monitor is working since I am using it to use my pc. In summary, I use the same monitor and the same HDMI cable for my ps4 and my pc, but my pc is working and my ps4 can turn on but it shows a black screen.
could be a bad hdmi port, bad hdmi encoder chip or bad filter theres a few things that can cause black screen
