Knoll Systems HDO2200 - 4500 lumens!

I don't know about this model, but a few years back my store was a Knoll retailer. At that time, they were very, very similar to Infocus projectors, even down to the case.

Now I don't want to throw around the term "rebadge"', but again, at that time the Knolls seemed to share a lot of not all technology with Infocus.

4500 Lumens, 3000:1 contrast, looks like a typical, nothing-special business class machine.

Here's a Vivitek with similar specs:

And a BenQ

Knoll sells a number of PJ's that are rebadged other brands, but because they do something to them they can be called manufactoried by Knoll. There are lots of Business class high power PJs out there.

The hard thing is to find a true HT PJ with that kind of output at a decent price.

I personally wouldn't put any stock in PJC's calculator for lumens or screen brightness, given that there's no information on where from or how they get the numbers they use for it.

If you want a really bright projector with good contrast for home theater, unfortunately you've basically got to look at Projection Design, Digital Projection Inc, Sim2 and the like.

Like I said, I am not going to call the knoll a rebadge since I dont have the expertise to do so.

BUT, if you look at the other projectors in the Knoll lineup, they are identical in appearance to Infocus products.

But you are right, it is possible in this case they did exactly as you say, and it is indeed a unique product.

If you have a large screen, this might be the ticket!

Knolls Systems is local where I live, few years back I was going to buy a projector directly from Kevin Knolls. He was telling me that they were buying the projectors from Infocus but all the software in the projector was from Knolls and thats why they weren't just "rebranded".

I didnt end up buying one from Kevin but my boss did and has had a lot of enjoyment from it over the last 4 years.

That's really not that hard, assuming you're talking home theater 3 DLP machines, there's lots of business class DLPs that are in the 4000-5000 Lumen range.

What is hard is doing that with contrast that would be considered acceptable in a Home Theater environment. That's really what you're paying for with a 3 DLP machine, high brightness and high contrast. This thing is only claiming 3000:1 contrast, which really is nothing to write home about.

The contrast ratio of 3,000:1 is a very low number unless it is ANSI and it is not in this case. Most Prjectors are below 400 ANSI contrast but list absolute contrast. 3000:1 is not bad, but not great for a home theater. Without seeing the PJ, it woul dbe hard to make a determination.

A DPI is going to have way better contrast and an overall much better image. There's really no reason to think anything special is going on here, it's spec'd and priced like a bright business machine.

If you believe their number that they have a 4500 lumen calibrated at D65 machine and seem to be the only one who can provide this at under $30,000 go for it. Otherwise no it will not produce 4500 lumens calibrated and if it does it will not have what many consider good contrast.

You have to remember good, low noise, bright, etc etc are not defined and what you think is bright is not to someone else. What you think is a good contrast is not to another. You have to decide if this is good enough for you.

Look at the CRE thread they claim 3000 lumens from a LED chipset that nobody else has been able to get even 1000 calibrated lumens, yet the company stands by their 3000 lumen claim and say color are very good. If you consider everything being redish or yellow very good then yes... for most of us we would not consider that to be good.

new here.... thanks for the warm-welcome !!

have one running right now in my "Lab"
has decent light-output.... grey screen / high-ambient
will know more by next week when we install
I suspect they have to remove at least one segment of color wheel ( as do other manufacturers) when attempting
to achieve these output specs.

just hung it from ceiling mount, in light controlled room.
Not calibrated yet. fairly bright.... terrible artifacts of some sort. not sure if it is mirror "dither" or other blotchy artifacts that
are potentially related to the cable signal .... although I have never seen these same artifacts on this same system / cable box
( with other projectors)

I am withholding further contributions / opinion until I get to run BRD on it this week. Sorry I just do not want to rely entirely on the local cable providers signal

I don't have a comment on the thread, but I do find the OP's screen name to be hilarious.

probably should have gone with Shreadedpork ....
the things we'll do for anonymity

watched BluRay yesterday on 49 x 87 ( 100 diag) white 1.3 (probably Draper .... relatively inexpensive) screen
this projector is impressive from a light-output standpoint. My guess is that they've done something along the lines of
a clear color-wheel segment or multiple clear segments to achieve the brightness level
There is a bothersome artifact on both BluRay and the HD cable sources. My friend, the homeowner , and "Borrower" of
this projector (whilest his gets fixed) used the word "Sparkles" .... and really looks forward to getting his back
I am not ISF-type-expert enough to know what term to use. Possibly mirror-dither ??
it is annoying .... that's for sure

But hey, let's be realistic .... would we be talking about a 4,500 lumen 1080p DLP , under $3K just 5 years ago
or even 2 years ago ??

we're getting spoiled

I would put it this way ... if you find video-artifacts , "Sparkly" and otherwise , to be as distracting as I do , you will probably never
be satisfied with this projo. spend the extra Grand and get in to something like the new Runco LS-1
The KNOLL is bright and would fill a large screen , therefore it might be a perfect fit for someone with a multi-purpose room who would prefer
sports / entertainment, over film-viewing.
Tomorrow it will be permanently installed into the home theater of the one who is actually purchasing it , and if my opinion changes
I will post my reasons. there may be some delay due to the simple fact that the permanent screen is on back-order
