So...who makes a 1080p PJ worthy of a 150 inch screen?

projectiondesign Action! Model Three 1080 is the projector you might like to consider for that sort of screen size.

Dual lamps, dual color wheels, virtually no rainbows and sharp images. It comes with the Crystalio II [VPS3300]. You can also request the VPS 3800 at an additional price.

The downside is that it is pretty expensive.

Projectors in the Pearl price range may not have the lumens to brighten up a 150" screen properly. Either you might have to go 720p or you might have to consider a smaller screen size with a 1080p pj for an optimum picture at your price range.

It will be a good idea to contact Jason Turk, Tryg Hoff or one of the other AVS reps who can help you formalize an ideal combination of products that give the best result within your budget.

Genereally any 3 chip 1080p DLP would work. Possibly the new JVC but not sure on that yet.

I know it was pretty bright at the show in September, so I have high hopes.

hi
different solutions:
- perhaps the JVC RS1 but change lamps after 500hrs
-use a high gain screen
-black room of course
-forget marantz and sharp and benq 10000
-PEARL limit.... (gain definitely)
-new Projection Design 1DLP 1080 in january < $10K, they are bright generally
- of course the PD Model 3 1080p 1chip is very bright (2000ansi)

there really is a problem in the <$10K range with those 1080p projetors: no real brightness for 3meters- 4meters 2.35:1 screen unless you use a high gain screen.

The Sharp is actually quite bright, if you leave the Iris open, and could certainly handle that size from an image quality standpoint, but I still think you would probably need in excess of 1000 lumens for a screen that size, with no gain.

The Optoma HD81 had no problem lighting up a 150" 2:35 screen, but I don't think it was a
unity gain screen. I know it was a DaLite, and it probably had some gain. I also know that
the bulb was not on high and the iris was not fully open. It is a bright projector--at least
before calibration, having a 300W bulb.

The only projectors that would be bright enough for a 150" 2.40:1 unity gain screen would be very expensive 3-chip DLPs: projectiondesign, SIM2, Digital Projection, etc. These come in at around 30-40k.

Yes, but they offer crappy home theater performance. These projectors are designed for business applications, Powerpoint slides, etc, where the needs for processing, color fidelity, and contrast are MUCH more modest.

You are really limiting yourself with this choice of screen. Is there some reason you are wedded to unity gain? A Stewart Ultramatte 150 would open up A LOT more projectors for your installation.

Gee, I would have thought that someone with a 150" 2.35:1 screen would have been "an elitist viewer" pretty much by definition.

I won't make any judgments about the quality of this PJ as I haven't seen it other than to point out that the reviewer compares it to the Panny 1000, which a lot of folks here have pretty much dismissed as a high-quality HT unit. But if this is what you want, it seems to have the lumens.

I don't understand your comments about DIY-ing screens and about results speaking for themselves. I was referring to the amount of light you would need at a given screen size and gain to achieve acceptable levels of brightness. This has nothing to do with your skills or with getting a "better" screen to offset a PJ's shortcomings. It has to do with matching the PJ and screen together. If you want high quality, and by that I mean a quality comparable to the crop of recent 1080p units now on the market, with sufficient lumens output for that screen, you are looking at a very expensive projector.

Even 800 calibrated is low for that screen size considering 100hrs into it you lose up to half that. A gain of about 1.5 would set you up just right however - and that sounds like it's not an option after perfecting your screen mix...

Perhaps a 333 720p three chipper is in your future?

"Perhaps the newly touted JVC will change all that. Jason claims 800 calibrated lumens."

Not so; all he has done is pass on JVC's specs.

Not sure Noah, but I think "the word" based upon discussions with JVC, as reported by other here, is that the 800 lumen figure is calibrated. Normally I would not put much stock in that but the HD2K was rated at 500 lumens and it indeed met spec when calibrated. So hopefully this one will. Of course playing devils advocate, JVC could always have decided to not follow their previous steps and that's why it's now 800, and it will measure 500.

Personally, I'll take a guess and say it will be close to 800. Fingers crossed.

I'm not questioning the claim, just that it's Jason's.

Optoma HD81.

We did a 170" 2.35 demo at CEDIA
Discuss link here

The screen was Stewart HD130, gain 1.3. The 170" screen area is about 1.28x of 150" screen, so that would make the image intensity on a 150" unity gain similar to the CEDIA demo.

At CEDIA, I set lamp at full mode, and IRIS at step 5, not fully open, meaning it has potential for larger screen.

FYI.

Hello TzungILin,

I have not read the 1000 page HD81 thread . So would you mind telling me what a user can expect from the HD81 when calibrated to D6500? I see on your website it is rated at 1400 ANSI lumens but I assume it is less after calibration?

BTW, just an FYI. It would be really nice (for you too if you want web traffic) if typing in optoma.com actually took a user to Optoma's website. Instead you require the www. Not good .

QQQ - If you have a windows pc you can just type optoma and hit control enter and it will add in the www. & .com and take you there. I haven't actually typed www. and .com in a very long time.

Very cool tip MrLittleJeans. Much appreciated - I love time savers.

That is the best tip I have gotten from this site in quite some time!

Not necessarily. It depends on some settings...

See the Infocus 1080p thread. Reported to be 1200+ lumens. Available in August.

If you clarify if diag or width and zoom to fill or anamorphic lens - then the required calibrated lumens calculation can be done. Amazing that everyone threw out their preferred solution without even asking the most basic install questions.
