Ok Ok, I have read and read but just decided to ask the experts out here a couple of questions.


1. I have a 64x80 in screen that is exactly 16'4" (196 inches) from where the lens on the projector will be located. Will this work with the standard lens?


2. I have a Sony HD100 HDTV receiver / set top. What kind of quality can I expect with this setup.


3. Is the HTPC "ABSOLUTELY" the way to go or will I be ok with just a normal DVD player?


Any input is always appreciated.

Thanks!

From that distance, your width range would be 66.9" to 103.7", so an 80" wide screen would be no problem.

Projector Central's Projection Calculator is your friend.

3: YES HTPC all the way or you could use an external scalier like the Rock. The DILA's have horrible internal scaliers. If not I would be watching mine right now. My DVD drive died Saturday. So I'm hoping Digital Connections has mine on the plane.

Sean,


The throw ratio for an 80" wide screen at 196" is 196"/80" = 2.45 which is within the 2.1 to 3.1 throw ratio

range of the G15.


The permissible screen widths are 196/3.1 = 63" to 196/2.1 = 93"


Your 80" will fit in the permissible range.


Now let's check the luminosity. The area of the screen is 80" X 64" = 5120 sq in = 35.555 sq ft.


The luminosity is 1500 / 35.55 = 42.2 ft-lamberts


That's a bit on the high side - but you should be OK.

I don't think youll get 1500 ANSI lumens out of a G15, even uncalibrated. Calibrated you'll get around 850. He also didn't give his screen gain.


I'm getting around 30 ft lamberts on an 80" wide 1.3 gain Stewart microperf, and it's definitely not too bright. It looks great!
