Hdmi hook up between denon reciver and a playstaion3?

-I have a Denon AVR-2808CI and I have the hdmi cables pluged in and some settings set but for some reason ihave sound but no video. I tried every setting I could think of but still nothing if anyone can help that would be super helpful.

Thankwould have to know a lot more of how you hooked it up, as in do you have the correct hook up from the denon to the monitor or from the playstation to the monitor or from the playstation to the deneon, etc.
let's worry about the cable - hook it from the game box to the TV to see if that works

if the cable is OK, you must have set the Denon so that it thinks the HDMI input from the game is only for sound
