I began setting up my projector today and have a few questions, as well as an observation.
1) I currently have a projector stand, because my ceiling is too high and the back wall has a swamp cooler in it, which I've always worried would shake the projector too much. The current screen is 110", which required me to move the stand about 4' closer, just behind my couch.
However, the display was trapezoidal, which led me to believe I was tilting the projector too far downward, so it I lowered the arm on the stand and tilted the projector upward. That lessened the trapezoidal effect, but it's not totally gone and it's not possible to lower the arm further. So I am now wondering whether it would be to my advantage to flip the arm of the stand upside down, and then reverse the image. Assuming that works, one benefit is I could raise the stand's arm, which would decrease the likelihood of hitting people's heads at the edge of the couch.
2) What's the benefit of using the zoom? It seemed like I could make it fit either way, but I'm assuming one method is optimal.
3) I live at 7800 feet, so it's pretty obvious I should use the high altitude setting. However, the sound of the fan went from, "Man, I can hardly hear it!" to "Whoa, what just happened???" Since the ceiling is very high (18') and the house is incredibly poorly insulated, leading to a cool room, would I be dramatically shortening the life of the this machine if I didn't use the high altitude setting.
4) Very obscure, but has anyone installed a projector in a wall with a swamp cooler? We never use the swamp cooler while watching TV, due to noise levels as well as temperature complaints from my lovely bride, but it will run for 4 to 8 hours a day during the summer. Would this shimmy a wall mount too much if I use it rather than the stand? I'm starting to like the concept of putting the projector in a place that can't be accidentally knocked.
5) My previous projector was the H31. When I would turn it off, I'd press Power and see a message of "Power off lamp?," then press again. The lamp would immediately shut off, while the fan would run another few minutes. However, when I turned off the unit today, there was no message and the lamp wouldn't turn off immediately. After 20 seconds of not turning off, I turned off the power.
What was I doing wrong?
6) An observation: This unit may be bright, but it's not bright enough to overcome the light I have in my room with my room darkening shades up. (I didn't test with the shades down). Not a big deal, but if you have lots of windows, you'll probably have to wait for darkness to enjoy the picture.
