I have just purchased the AVR-X2400 and have it hooked up to my Hisense 65u7a TV Watching content on my Firestick 4K through the AVR went smoothly but tonight I tried to connect my PS4 (not the pro, so just regular 1080p content) I get... Nothing. I tried changing HDMI port on the AVR, no dice. I swapped the Firestick and PS4 around. The Firestick works five in the 'game' port but the PS4 shows nothing still in the other HDMI ports. The TV screen flicks between static and black screen when on the PS4 source through AVR. Not clear if this is the TV or the AVR causing it. The screen on the AVR says ''Multi in" but I don't know what this means and Google didn't help me. I tried the PS4 plugged direct into the TV and it worked fine. The TV HDMI port is HDMI 2.2 though since this is not 4k current and the 4k Firestick worked, I don't think that would be the issue. I ran setup on the AVR for the PS4 but it didn't make a difference. The only time I have seen anything is when the PS4 was updating, I saw the progress bar. does anyone have any idea what is occurring?
