Hi all,

Thought I'd post this image I made up (my setup/basement) which has some numbers on it that others here might find interesting / helpful in determining their setup.

I calculated the dimesions for an 8' wide screen in 4:3, 16:9, 2.35:1
And for a 5' high (6.66' wide) (size of standard blackout cloth) in 4:3, 16:9, 2.35:1
And a comparison to a 60" diagonal 16:9 regular t.v. for a comparison on square feet of screen.

Click the image.... looks like crap if not at full size.

Why not put the projector in the closet and the screen on the right side. Then face the couch to the right. That way the projector is completely hidden (other than the lens) and your screen will look like a flat panel display. Also, it will put the bathroom beside you instead of practically in the line of sight of the screen.

This is why... pool table... video games... already wired... etc.

Fully finished by the previous owner with in-wall wiring for surround in that configuration.... he had a little 60"er in there

Mine will be ceiling mount (9.5' ceilings)... not sure how big I'll go with the screen ... either 100" or 120" ... might even mount to the industrial strength slider (local surplus place has them) so I can move the project back and forth within about a 4 foot range to vary the screen size.

Here is another diagram I made up.

I based the calculation on that a standard triplet gives a 10' wide 4:3 image from 10' .....which gives a 41.1 degree height arc for the projection at 4:3 and a 53.1 degree width arc.

The height arc is angled down at 8 degrees from horizontal ... triplet is 6.5' from the floor.

I'm building my projector on a sliding ceiling mount that will have about a 30" range of travel...

I'll be able have the triplet in the range of 83" -> 113"

I tried this out last night, measuring the projector on the wall... angling the projector/keyston correction may throw things off a bit, but this diagram gives a good idea what you'll get with the standard triplet/lenses.

My ceiling mount is using two industrial strength drawer sliders and four - 3/8" threaded rods that the projector hangs from on small L brackets attached with wing-nuts.... should make it easy to adjust the angle of the projection.... and at a max of 10 degrees keystone, the image should be nice and square for either setup.

Pics to follow in about a week
