Another newbie needing PJ selection help

Hey Cam,

Is your 120" a diagonal or width? Most of those projectors would have enough brightness for the screen though it depends on just how bright you want it.

THe RS1 is one of the brightest. The new VW60 from Sony would be okay. THe HD81LV would also be bright enough. You could also throw in the IN82.

I think what we could do is once we know the measurement (width or diagonal) we can do some calculations for you and you can see how many foot lamberts you'd have and make a decision based off that.

120', WOW! Sounds like IMAX

I can't imagine the size of his house!!!

my room is 14'x25' with a 8' screen. the screen size enabled me to sit closer to the screen and have two rows of seats and a two seat bar table in the back of the room. I get a good image and I can move my projector closer to the screen in front of my ceiling lights. Size is not always better.

Okay there are many things that go into screen size. How far do you like to sit away from, or in proximity to, a theater screen when you go to the local Octoplex? Do you think that screen is dim or bright?

If you're planning sports you may have the lights on at times. To combat ambient light, if any, usually a higher gain screen with a gray base material helps improve black level and foot lamberts.

If you, like you said, you want to focus on this as a movie theater mostly screen, then I'd recommend a white material with a slightly higher gain. Much like Stewarts Studio Tek 130 which is 1.3 gain.

We can get into all the back and forth details of course but here is what some of these projectors will give you in terms of light output measured as foot lamberts. Please note that these measurements are taken from Jason's reviews and what we've measured here at the AV Science lab (makes maniacal cackling sound as lighting bolts bounce back and forth between two radio towers).

Here are some fl measurements.

Screen = 58.75" H x 104.5" W x 120" D

Sony VW-60: 500-600 lumens regular use = 17 ft lamberts (1.3 gain screen)
RS1: 500-600 lumens regular use = 17 ft lamberts (1.3 gain screen)
In-82: 500-1000 lumens regular use = 20 ft lamberts (1.3 gain screen)

These are averages but bear in mine, a movie theater is about 13 fl with film in the gate, 24fps.

Not bad.

Cam,

You take the height of the screen and multiply by 36% and that's how high above or below the screen the projector can be mounted.

The RS2 is rumored to have even less lumens thatn the RS1. It will have some other improvements though. We'll wait and see then for you.

What is important to you in terms of ANSI contrast, black level, pop of color? Where would you rate these?

Richard

Cool, when these projectors come out we'll list the strengths and advantages. But normally color edge goes to the DLP side. Brightness usually to the LCD or DLP if it's a 3chip. Depends though if you're using a xenon bulb which is brighter like in the new Sony VW200 vs straight LCOS or SXRD. Though SXRD and LCOS is known for it's black levels a la the Ruby and upcoming RS2.

Oh the humanity! So many choices...
