Acer K750 LED/Laser Hybrid - Page 4

post #91 of 244
Now available in US apparently - $1799 at Newegg. Link below:

Acer K750 1080 LED/Laser

Did Kraine keep his?
post #92 of 244
He sold it for Sony HW50ES
post #93 of 244
Does this PJ have a Darkchip3? Guessing unlikely given the price.
Still...tempting for everyday 1080 viewing in place of a flat screen.
Then compliment it with a higher end, traditional bulb, PJ for bluRay.

Here Link it says it does use a darkchip 3. But this is the only place I could find it, so don't know if it's accurate.

I like the under 2k price smile.gif better than the Panasonic, Viewsonic and BenQ, led and laser. Wonder if the build is better or if heat will kill it off after a couple thousand hours of use.

Edit: fingers crossed, low lag and fast response for gaming smile.gifsmile.gifsmile.gif

Edit2: Can anyone find the k750 on the Acer site? http://us.acer.com/ac/en/US/content/models/projectors

I found a review of this PJ, just came out.
http://www.avforums.com/reviews/Acer-K750-LED-Laser-Hybrid-DLP-Projector-Review_369/Review.html

Although this doesn't sound good!

The big selling point of the K750 is the LED/Laser hybrid light source which Acer claim can deliver 1,500 lumens. This number must have been the result of the same creative mathematics used to produce the claimed contrast ratio. Once you had turned off all the features that maxed out the light output, which created errors and clipped the whites, and used a screen larger than a postage stamp, the actual brightness was a more sobering 800 lumens.

The French and Chinese reviews noted earlier in this thread (see links) gave a positive opinion. I wonder if avforums got a bad unit?? Hopefully Art or another US site will do a review soon.

Funny, you're right, nothing on the Acer website yet. Slackers...

Here is from the French Review site, translated into english on brightness (lumens).
http://www.audiovideohd.fr/tests/334-Acer-K750-4.html

Standard Mode Brightness: 334 lux (876 lumens) Eco mode to normal mode. 230 lux (603 lumens)
Movie mode brightness 176 lux eco mode (461 lumens) and 238 lux in normal mode (624 lumens)
Presentation mode brightness: 378 lux (991 lumens) standard mode and 266 lux in economy mode (697 lumens)
Best value of the black light mode after calibration: 0046
Eco Mode: 0015
Native contrast calibration mode after saving lamp: 11733:1
Native contrast after calibration lamp mode normal: 5173:1

Wonderful - how can they list it at 1500 lumens? Maybe it depends on the distance and that number is based on small presentation rooms?

Any idea on actual lumens for the LG PA70G (listed @ 700 lumens)?
I know the LG is less expensive, but I think its not 1080p.
post #99 of 244
Comparison from a German magazine:
http://www.heise.de/video/artikel/Projektoren-Laser-statt-Lampe-1733201.html
At 00:50 cinema mode with 464 lumen, at 01:00 high brightness mode with 1195 lumen and terrible colors.

From reading the LG PA70G, it sounds like alot of them have focus issues, and yes 720p.

Comparison of Acer K750, Sony HW50es, and HD trailer on YouTube using Snagit:
Not scientific of course, but just so happens to be recorded by the same person, the same trailer, and recorded roughly at same angle for the Acer & Sony. The Sony looks bright!

Yeah, especially when the LG PA70G first came out many early production units had focus problem ( some members were able to do simple fix by adjusting a couple of screws to fix it). But is seems that more people NOW are getting focused units.
It is 720p. But for tv and movies and games I don't find it a problem, it produces a smooth picture.
Now when on sale the LG PA70G (700 lumens) for 399 dollars compared to sale of 1799 for this acer k750. 4x as much. Especially if the Acer is not in user experience 1,500 lumens but closer to 800 lumens.

A couple more grabs for loose comparison: K750, HW50es, HD Trailer

To me that looks like someone is trying to make the Sony look worse than the Acer on purpose, proper calibration would go a long way to showing the Sony likely throws a superior image (just a hunch wink.gif).

Yikes, fair point - That never crossed my mind as I know the Sony should be a much better unit, particularly in person. The reviews appear to be in German - so no idea what is said by the reviewer.

I chalked up the difference due to the stronger brightness/contrast of the Sony throwing off the colors on the reviewer's camera.

Regardless, I'm hoping someone in the US does a review with a comparison of the Acer to the Viewsonic Pro9000 and some LEDs like the LG PA70g or Qumi5.

Price down to $1699 at the moment on the Egg.

Some follow-up info for future viewers interested in the K750:

Lumen output on the 720p (1280x800, 16:10) LG PA70g measured at 300-330 lumens, or ~45% of list of 700 lumens. (link to LG PA70g thread). A forum user was kind enough to take the measurement with a new light meter, but cautioned that a more formal test should be performed to help confirm the numbers.

Some other 720p LED PJ output for comparison: Testing on projectorreviews.com for the Optima ML500 and Acer K330, showed lumens to be roughly 60% of list of 500 lumens (~300 lumens) in Movie/Cinema modes on those LED models.

The 1080p LED/Laser K750, listed at 1500 lumens, registered from 600 to 990 lumens in a French review (or 40-65% of list).

Also here is a link to a PDF article by Runco concerning LED brightness, contrast, & perception.

Please keep in mind that my measurements are for a 100" matte white screen (nearly 30 sq.ft @ roughly 11' throw and 1.0 gain), the PA70G would be capable of hitting the spec lumens on a smaller screen.

The problem with making these general comparisons is that we do not have a standard method of measure for leveling the playing field. wink.gif

post #109 of 244
is there a color wheel for K750? and is there any similar models to been released this year?
It seems currently only K750 and VIEWSONICE PRO9000 available in the market.
What about Optoma and Benq, is there any rumors?
post #110 of 244
Optoma HD91 due this autumn (September, I think).

Looks like being an LED version of the HD82/87-ish sort of range.

Very, very few details at the moment.

Down to $1499 at Newegg - I'm surprised no one has jumped on one of these. Aside from the AVForums review, which left some questions unanswered, I haven't seen much out there on this. I'm considering replacing my K330 with one, but I'd like to know that this doesn't have the same focus issues (changes as projector warms up, and focus not uniform across screen) before purchasing one.

it could be .. but other factors not jumping into it is that
1- no 3D
2- sharpness is not where it suppose to be
3- no frame interpolation
4- pricey at that time in which didnt catch customers attention that much ( nothing so spacial about it except being an hybrid tech )
and there was a long arguments about the price will turn to be this year from last year to $1,5k Here
5- it just a pricey mid range projector to look for !!

now BenQ W1070 roll over and its a winner ( IMO )
post #113 of 244
I get the feeling that the PJ is not selling well. I was tempted at $1499 but I don't like the Egg's return policy on the unit (replacement only).

Would love to see one for myself but very little info is out there (as you mentioned,) and only the Egg is selling it from what I can see.

Even stranger is that the K750 is still not listed on the US Acer site.

I really don't care about 3D or FI, but could you expand on the sharpness comment? I may have missed it in my reading, but I haven't seen anything that indicated that the projector had issues in this area. Granted, we're talking about a $1500 projector with a new type of illumination, so I wouldn't expect it to be as sharp as say a $5K DLP. I'd be using this as a travel unit, so the size is appealing, and the ability to turn it on and off frequently or leave it running for long periods of time without worrying about aging the bulb is quite appealing to me. I wouldn't use it on larger than an 80" screen, so it has more than enough lumens for my needs.

I definitely find that strange - I'm not sure how they can sell a projector in the US and not have it listed on their website. It's one of the reasons I've held of on buying it. I am however thinking of eating the restock fee just to get my hands on it for a bit.

you can google Acer K750 reviews .. you can find out how good it is

all in all PQ is about mid range projector ( Acer K750 vs H6500 )
its not better then benq W1070 ( IMO ) which is less then $1k when it comes to sharpness and 3D
the only thing makes it better is the advantage of lamp-life worries and on and off

last year it was like $2500
and now its down to $1500 is just about right ( IMO )
can you imagine whats the real price of Acer K750 - jumping from $2.5k to $1.5k in just 8 months time
are they ripping off ( I cant call it that ) or it just happen to be the roll of marketing to x3 the real price until it just like 2 years and still making some money out of it !!
is this the tax of tech !!

anyways ....
Panasonic PT-RZ470 is out for about $3.5k here ( or google it )
and Optima HD91 out in Sept

if you are not in a harry wait the end of this year for a better one in the range of $1.5k
or you can go for it now - your call ....

good luck

Yeah, I've already searched for reviews on the projector, and there are none aside from the AVForums review. All the other articles titled "review" - including your link to the K750 vs H6500 "review" - is, at best, a cursory summation of basic features and performance. Unless you're assessing image quality based on screen shots - which is about as useful as reviewing speaker performance by replaying recordings of various speakers through your laptop - then I can't find anywhere that addresses any specific measurements of various PQ aspects. I certainly can't find anywhere that offers a comparison between the W1070 and the K750. If you can point me in the direction of something definitive that I'm missing, I'd love to see it. Otherwise it seems like a lot of conjecture based on minimal, incomplete information about the K750.

am not saying its a bad PJ at all .. i haven't sow it in person ( Kraine and some other reviewers does )
and you can go for it with price $1.5k wink.gif

and no comparison k750 vs w1070 .. it just the features you going to miss from one to another
and look to w1070 thread how far it takes !!

all i can say what Kraine said before about it
its a good PJ but lack of some sharpness - 3D - FI - lens shift and ...etc
all i mean you cant compare it with an old school bulb with the same price

I my self bought LG pa70 6 month back for the same reason you have
and my mind playing tricks of buying k750 ( for the same reason you said ) $1.5k is attractive wink.gif
but am like waiting for couple of months to but things right with high end one ( LED or Laser or Hybrid or what so ever comes up better )
until then saving some cash and bare with 720p biggrin.gif

post #119 of 244
In his review of the Viewsonic Pro9000 (laser hybrid), Art from projectorreviews.com mentioned that the hybrid technology is roughly worth $1000:

"How long you plan to keep the Pro9000 is going to be a key decision for you, because, in reality you are paying roughly $1000 for the light source."

So I'm guessing that the K750, which sports a Darkchip3, is the new H6510bd married to the laser component??

Tempting... really just want a similar priced Flat screen replacement with 1080p + on/off willy-nilly use and flexibility.


***Edit - whoops just noticed that the Acer H6510 is 3D capable... so nullify that marriage.

thanks SiggUA
PT-RZ470 Kraine said somewhere it wast well presented
anyway someone got his hand on it and will try it out .. and primary its not a HT design
and Kraine said something about HT one will come out at the end of this year or the start of next Year
lets hope next year no more ordinary bulb to be seen and 2013 is like the way its start lampless tech biggrin.gif
