Thanx,this is the answer I'm looking for.

Native contrast calibration mode after saving lamp: 7400:1
Native contrast after calibration lamp mode normal: 1244:1


The only difference between these numbers is low and high lamp?

I don't understand that. I've never seen contrast improvements like that from only the lamp setting, unless this LED projector is doing some sort of dynamic brightness control on the lamp/LED in the low lamp mode?

Thank you so much for the link. My PJ died last year. Waiting for a decent LED based replacement.
Merci grandement pour le lien. je l'ai gardé dans mes signets.

so which one would you take,the winner in a simple plain English,the acer k750,viewsonic pro9000,if you are looking for overall PQ?

I will try to translate what is written in the "Conclusion" section:

Cons: Brighter than the K750 but has less contrast.
Color is" off" out of the box (it has no gamma editor).
CMS needs improvement
No lens shift


Pro: Once calibrated, picture is better than most pjs
Sharp picture.
More than 20000 hrs lamp life
No heat, no warmup or cool down needed. Instant On/Off
3 years warranty.

kraine thanks a lot for what you give people the review and imprison

so you choosing K750 over PRO9000
i was not expecting that .. the PRO9000 got a sharper image ( as i predict ) !!

anyway one of those tow may come up with new firmware and fix the bugs out of it tongue.gif

again thanks a lot Mr kraine for all efforts smile.gif
post #126 of 202
thanks Kraine.
you have said that you will move to LED projectors and forget about lamp projectors, why did you change your mind? are LED projectors not good enough?

Yes shame on me tongue.gif But after a couple of hours watching the new SONY VPL-HW50ES, I have changed my mind biggrin.gif
post #128 of 202
Any info on power consumption for this, or any of the new laser/led projectors?
post #129 of 202
Kraine,

Can you comment on how the K750 or PRO9000 compares to more common lamp based DLP home theater projectors, like the Mitsubishi HC3800/4000, etc.??
post #130 of 202
I've been going back and forth regarding what to upgrade next. So far these new led/laser hybrid projectors interest me most because no need to worry about lamp replacements and because of that no need to calibrate every now and then. They use less power and are really quiet. 3D doesn't interest me so no need to involve that into this discussion. Now I'm trying to choose between acer and viewsonic. Kraine said that he prefers acer, but when I collected his test data to excel table to compare different projectors, I don't really see why he prefers the acer over viewsonic? Is it the better base black and contrast? From the data I'm looking at, yes the blacks are better, but only marginally(if taking into account that the viewsonic is way brighter at low lamp mode and still has really good blacks), and the contrast is also a bit better, but then again viewsonic wins at operation noise, has sharper picture and is a lot brighter at both operation mode(normal and eco). To what I'm looking at the viewsonic is better overall projector in my eyes.... am I missing something here?

I took acer results from movie mode because I guessed that those are D65 calibrated? Acer seems to be way brighter in other modes than movie mode.


In this table I made, all the data is from calibrated results and DLP projectors are without brilliant color. Base black dynamic results are with iris enabled.

Btw Kraine, thanks for the tests. Those are really informative to read, but using google translate it's sometimes really hard to read the test results when they are not in simple table where all the info would be easy to read. Also, in your web page acer base black reads in 0015 and 0045, so I'm guessing that it's actually 0.015 and 0.045 like I put it on my excel? If so, you may want to correct it not to make too many confused.

One other thing Kraine. Can you tell me in case of those projectors where I have putted the info in one box instead of two, are the results taken in low lamp mode or high lamp mode? For example HC4000, TW9000W, PT-AT5000E native contrast and H9500BD, W1200, HC4000 base black?
post #131 of 202
Now that's a scientific approach in choosing a projector smile.gif I like it. Thanks for the table.
post #132 of 202
can you please do a brief review someday about small LED projectors like LG PA70G or Qumi Q5. this will provide an impression for those small projectors

It's because the reading for both is the same, i.e., the Mits HC4000 native contrast is the same measurement in low and high lamp. This is what is normally expected with native contrast readings, there shouldn't really be a difference in contrast from Just changing lamp modes (unless there is a manual iris adjustment also). There of course will be a black level and bright level change, but there should not be much of a native contrast level change.

This is why I'm so perplexed over the Massive contrast changes from just the lamp level change in some of his tests. Especially the Acer K750 tests. It just seems unbelievable on a non-dynamic iris DLP chip PJ to have native contrast readings of what was measured.

I really wonder if his light sensor has gone out of spec, which would make the low level black levels much less accurate, and would also account for the huge differences in his on/off calculations between low and high lamps.

Coderguy,

What is your take on the huge native contrast differences between high/low lamps that Kraine has measured? The HC4000 and W1200 measures appear to be in range, but the measures of later PJ's appear to be way off, especially with the measurement differences just between low/high lamp. Perhaps when he measured the HC4000 his sensor/meter was in spec, but now it's not?

And the impossibly impressive native contrast measures from the DLP/LED Pro9000 and K750?
post #136 of 202
I don't know enough about LED based lamp technology to say, but on some of his other readings I think the divergence is because they were taken with IRIS OPEN / CLOSED (x30 and Epson).
There have been some measurement differences between Lamp High and Lamp Low (but who can say if its meter error or not), but in general it is very very hard to take an accurate Native On/Off reading above a certain point anyways.

Some of the more expensive light meters should give a good reading, but I do not know what he used to get those.
post #137 of 202
Yeah, that is the point I've been bringing up. Unless there's a manual iris involved (change), there shouldn't be much of a difference in the native on/off readings between low/high lamp.

As for the LED DLP's (the low end ones, not the $10k + ones), everyone has been measuring native contrast on the low side, like 1,000:1, etc....except for Kraine's measures. Hence my suspicion his meter might of swayed out of spec....

Available in the UK, Europe ,excluding vat for people outside European union.
nevertheless ,they are in limited numbers,and prices are fluctuating.
be altawfeeq ,is this what you say for good luck?

The luxmeter that I used for my reviews is mentionned on every first page like here :

Maybe borrow or rent a 2nd light meter just to make sure yours is still reading correctly (not saying it is not, just an idea though).

I have a second meter less accurate than the first one, but as I do and write all my reviews for free I will accept every kind of donations to help me to be more precise in my test tongue.gif
post #143 of 202
I hear you, I'm not trying to give you a hard time, but it's just we have some odd numbers coming from your new JVC measurements vs. Sony brightness as well, and then we have some semi-odd numbers in the LED measurements (maybe they are right). Now even you gotta admit it was odd that the newest JVC came out that DIM. Maybe since it was a pre-engineering sample something was wrong with the PJ, so just seeing all these strange numbers coming from the same light meter has made many of us in the forums suspicious of the numbers (not your fault), but you know us here in the forums are the suspicious types.

Viewsonic always releases horrible firmware at first, I don't know why they always do that. Although it is a pre-production unit Art had, still it sounds like the same issues the Pro8200 had (but at least with the Pro8200 the color was pretty good OOTB). It didn't bother me on the Pro8200 considering what I paid for it, but this is a MUCH more expensive unit and I'd not expect to get some half-designed CMS or user save bug with a PJ at this price.

Looking forward to the serious players, JVC and Mitsubishi implementing the technology, like pure laser PJs.

I'm sorry, but this review is full of bullsh@t:

I don't consider this Pro 9000 to quite make it to being "ultra-high-contrast," but all considered the blacks are respectable, but definitely not up to the Panasonic PT-AE8000, Epson 5010, Sony HW50ES Consider them better than the DLP Mitsubishi HC4000, and close to the Optoma HD33, or the LCD Epson HC 3020 and HC3020e.
He doesn't consider Pro 9000 to be ultra-high-contrast and considers Optoma HD33 and BenQ W7000 to be the ones?
And what's with these photos? http://www.projectorreviews.com/images-projectors-q4-12/pro9000_5thelement_starship_over_large.jpg

Uhm, he doesn't class the HD33 as "ultra-high-contrast", he said of it: Black level performance of a typical entry level DLP projector, not bad, but not "enthusiast" calibre

He does class the W7000 as ultra-high-contrast, though due to it's aggressive iris. It's inline with most other reviewers.

This is what he said about comparing the Pro9000 to the Mits HC4000>> Mitsubishi HC4000 - one of our favorite lower cost projectors (under $1500): This is probably the closest overall, in terms of the combination of shadow detail and blacks.

So basically the Pro9000's blacks/shadows is on par with the HC4000, but the Pro9000 needs a DI to do it while the HC4000 gets it natively. Sits about right where I think the Pro9000 is----perhaps around 1000:1 ---1500:1 native contrast performance, which is brought to around 3000:1 with the DI on.

Sounds about right that he didn't class the Pro9000 as a 'ultra-high-contrast' PJ.

I dunno why you're calling BS on this? confused.gif
