I've been having some intermittent issues with my xbox 360 over HDMI in 1080p, and hoping that someone else has had the same issue and can help me pinpoint the cause.


Problem: When I try to run 1080p from my xbox, I get random red 'noise' pixels on the screen. As soon as I switch to 1080i, the issue goes away.

Now I have successfully run 1080p from the setup, this just started happening in the past week or so and I haven't changed anything.

Setup in a nutshell -> 360 to receiver via 6 ft HDMI...receiver through 25 ft HDMI to projector wall plate...wall plate to projector via 6 ft HDMI.


The HDMI in the wall is 24g, the rest are 28g.


I'm certain it is not a faulty cable, as I've run the same exact setup, substituting the xbox for a ps3 and running it at 1080p...and perfect picture.


The only thing I can even guess it might be is that the 360 is not outputting the 1080p signal strong enough (compared to the ps3).


I'm hoping that it's not a bum HDMI port on the console...


any help is appreciated on this...

The cables may be marginal for 1080p which gives you occasional dropouts (the red pixels). One thing to try would be a repeater/equalizier, such as Monoprice and others sell, at the projector end (not the transmit end) of the cable. It equalizes the distortion that long cables generate which can cause errors in decoding the digital signal.

Cut out the middlemen, plug the 360 into the wallplate (bypassing the receiver and 25ft HDMI cable), then work backwards from there to determine if its a cable issue or the receiver or the 360.
