Put the kids to bed and finally had a chance to fire it up. Let me say this is my first projector and I have no idea what I'm doing and I'm jst learning from the community at this point.

My theater is not done yet (carpet goes in Wed), so I was just projecting onto a taupe colored textured wall upstairs. I ran through some of the test patterns on the AVS 709 mp4 directly connected to my laptop outputting 1920x1080 via hdmi.
Focus using the green grid that is built in seemed to sharpen up pretty well from corner to corner, but definitely best right in the middle of the picture.
Used both the standard crosshatch and the small crosshatch to do the pixel adjust. At first I adjusted red up one and blue right one which made the upper center of the picture look near perfect. I moved on to the horizontal converg pics and realized that the bottom right was way out, like showing double lines out. Ended up moving all the pixel adjust back to the middle setting (3) as that was the best overall. Upper left and bottom right are at odds with each other. I guess I have to pick which one I want to be better converged. The way I left it, red is a half pixel down in the upper left and upper mid of the picture. Blue is a quarter pixel off in those same areas. The zoned adjustment of the 48+ would have come in handy here for sure I am guessing.
I want to test focus some more. What is the best test pattern to use to test focus/sharpness? I see people use that NEC one with a bunch of text written in different styles. Where can I find that one?
I watched a few BD video clips from the demo disc. Everything looks pretty great to me. Picture is a bit dull maybe but I think that's mainly the wall. I used Kraine's recommended settings from his review.
Lastly, I notice a faint ringing/beeping sound coming from the rear left exhaust (while facing) of the projector. I can only hear it up close. 5-6 ft away and it is inaudible. Is that normal?
