For a few months now my Dell 2407 is unable to receive a signal from my PS3 through HDMI with the help of an HDMI-to-DVI cable. I was able to receive a signal before but now all I get is either a blank screen that gives the "entering power save" message or flickering white noise. I'm still able to get a signal from my PC and the PS3 can still detect HDMI device so I'm wondering if it's my PS3's HDMI that's busted or the 2407's HDCP chip that's busted?
