I recently purchased the HC3000U and will begin the mounting process in the next month, (Still finishing Man cave )I want a 16:9 format with a 96x54 view, My question is if I mount on the ceiling will I be able to place my screen close to the ceiling? I will need it high in order to be above the center spkr and component recessed shelves. I too am new to this home theatre business and I was reading the other day about someone claiming I would be limited on how high, or low I could project due to the limitations of the HC3000U limited lens movement.

I have a 9' ceiling and will have a 6" drop ceiling, taking it down to 8.5', I was hoping I could project roughly 1' - 1.5 ' below the ceiling. Will this distort the projected image if I mount on the ceiling at about 8' above the floor? I don't have the measurment of the top of the center spkr recess hole with me but it's roughly 36" to 42". I can bring the screen down to that point without tearing my will apart and rebuilding the shelves so hoping you projector experts come back with the desired news .

BTW great place and lots-O-good info for new guys, Thanks!

That isnt going to work unless you tilt the projector upwards and use keystone to correct the shape of the image.

Here is a Mitsubishi calculator. Make sure to select the HC3000

Ok, finally got the calculator to work for me, I believe I would have to use the keystone adjustment so am now asking if I will loose quality in doing so, I have to tilt enough to raise the screen by about 6"?

Next question, would I loose sound quality by moving the center spkr (POLK CSI5) to above the screen? It would be about 90" above the floor and about 40" above our heads when setting.

I could pull the rock off the wall and move the shelves and would rather do that then sacrifice audio and video.

Any input is welcome!

Thanks!

Well there are a lot of opinions on this, but most people who have actually seen a keystoned image don't seem much of a difference especially with the image moving only 6 inches.

Another option would be to tilt the top of the screen forward a few inches instead of using keystone.

Did the measurments this AM and reminded myself I was 36" to the top of the spkr pocket, this prohibits the straight forward projector mounting without using lens adjustment (which I'll inquire more about) The top of the component pocket is 25" from the floor and the bottom is 12" from the floor. I'm now wondering if putting the center spkr in that pocket might be an option. I built it 68"Wx13"H, at this time I have a DVD player, VCR player-(This will change to a combo) a TV/Satellite box, Reciever, and x-box, I need to do more measuring!

Thanks for your help GW, feel free to throw whatever you know out, it truely helps me decide what to do, thanks!
