Hi all,

I am posting this outside my build thread so it gets a few more eyes on it, I need help from the resident experts here on projector placement.

I had a plan in mind, but after seeing the manufacturers posting I am a little confused.

My plan was to put the projector about 1 - 1'6" from the ceiling to enable the projected image not to hit the front row in the back of the head smile.gif

Here is what I see for the Panasonic PT-AE8000:

219412
Uploaded with ImageShack.us

I am going for 159", so if I am reading this correctly (and I think I am not), but the projector has to be at least 3'1 down from the top edge of the screen? Is this correct?

If so that means the projector would have top be mounted about 4 feet down from the ceiling, that seems a little odd.

Help?!?!?!?

Thanks

159 what?

Are you planning on using the memory zoom function and a 2.35:1 format screen?

My experience with Pannys is that the lens for a ceiling mount needs to be at or below the top edge of the image on a 2.35 set up and can be higher Up to "H" in the table for 16:9.

Oops, sorry Big.

159 inch 16:9 screen. No plans for a 2:35:1 screen.

And that seems to make sense then, so I can mount upside down as high as the top frame edge, or lower (towards the center of screen)

Nope, you can do better. You can hang it uside down up to "H" above the top edge of the screen but I can't tell what H is from that table.

I took a quick look at the Product spec sheet and it appears that H equals 1/2 screen height but I wouldn't go that high.
