I have an optoma hd20 connected to hdmi directly to my Sony avr. To the ave I have a x360, pc, ps3, cable box and boxee all into hdmi.
I get video noise on the 360 only. Any solutions? Power to the projector an the hdmi cable all run through the attic. Any way to shield them from each other? Could this be the culprit and if so why not on te other sources?
Shooting in the dark here but did you check you're 360 video output settings? I assume you did but i know that my xbox needs to be adjusted all the time since i switch it to different screens regularly.
Other thing you could try is using different input on the receiver to see if its the receiver. Or try a different cable from xbox to the receiver. since it doesn't seem to be the cable that goes from receiver to projector.
That or its about to red ring. I know when my xbox died 4 times jsut before it died i would have video issues or textures not loading properly in games.
