Just purchased a Sony HW50 projector, installed it tonight. I'm curious about a couple things... 1. When I'm using 3D mode on the projector, there is an extra little whine from the projector, it doesn't sound like a fan, more like a quiet, but noticeable squeal. After watching a movie for a few minutes, you don't really notice it anymore, but it's still there. Is this a normal function of 3D on a projector or is my unit possibly defective? 2. I've gone through all the screen adjustments I can find via manual control and menu options and I can't get my screen square. The left vertical side is wider at the bottom then the top, the right vertical side is perfect, and the top and bottom of the screen gets smaller as you go right. The keystone seems to be for a trapezoidal effect, which I have on the left side of the screen but not the right? And there doesn't seem to be any adjustment for the left-right horizontal issue. I thought the screen might be crooked as its mounted to a bulkhead, but it measures perfectly from the wall. I attached a picture of the effect I'm seeing. The green would be my screen, the blue is the picture on it. Maybe my screen just hangs a bit crooked? Any ideas? Thanks!
