On your TV, in Settings>TV inputs>HDMI # (that the PS4 is connected to)>HDMI mode, have you tried changing this to HDMI 1.4 on both the TV, and then also in the settings of the Playstation 4? (You might also try manually selecting HDMI 2.0 on both devices and seeing if this option works.)
- Does this resolve the issue?
If not, please feel free to PM me with your Roku account email address and the serial number of your TV from Settings>System>About. We can continue looking into the issue from there!
