Here's the setup. HD70 Projector (1 HDMI input), Onkyo 7.1 Receiver (passthrough HDMI only), Comcast Digital box, PC (DVI Video Card, standard pc audio inputs), Xbox 360.

I would love to only run one cable to the projector and that's the HDMI cable. Unfortunately its going to require a 50' cable from the equipment rack to the projector.

So my questions:
1) Which HDMI cable from monoprice should I go with, and not have to worry about signal loss or "sparkles"?

2) How should I go about setting this system up?

Thanks!

I don't remember which monoprice cables have passed the 1080p test at 50', but I know that the Bluejeans cables have passed it.
