Acer is expected to launch the first 500 lumen LED projector this year before the likes of Optoma and Viewsonic.

The projector features:
1280x800 native resolution
5000:1 contrast ratio
500 ANSI lumens
3D projection support
Direct projection of files from USB flash drives

If the Acer K330 delivers on it's promise it could be a game changer!

If these streeted the exact same time it would make the decision harder but if the Acer does come out a month ahead of the others then it does gain a big advantage. Heck, if may even come out before the qumi if those don't get here this week. The only way I can see myself going with a qumi over one of the 500 lumen led's is if the people that get the first batch of qumi's report back that they are plenty bright for a 90" and under high power screen.

Question about this. Do you have to have an external box to make this do 3d? Or will it work straight through with a 3d source like a ps3 or blu ray player? Whats the biggest size this project like 100" or more

It states 3D support, but it lacks the lumens to do it properly (but it is still a nice little extra). Interesting.

Well, the Optoma ML500 specs states it will project up to a 120" image so the Acer should be the exact same.

On this forum it has been reported $699 for Optoma and $650 for the Acer and Viewsonic. I think Acer might have fudged the 5000:1 contrast number as Optoma and Viewsonic are reporting 2000:1 contrast for the same projector. Maybe Acer has a extra special contrast enhancer in their software for projector that produces the 5000:1 number.

What kind of LED engine does this have? Is a hybrid like the Casio?

I'm hoping the 5000:1 contrast ratio is not a mistake, and that Acer are looking to take the edge on the competition.
I haven't found numbers for the noise level on the K330. With any luck the Acer will come in below the rather high db rating of the optoma ml500.
Fingers crossed

The 500 lumen projectors being released by Optoma, Acer and Viewsonic are not identical. Although the projectors seem to share a 'base', they do have distinctive differences. As anyone else in marketing would know, it is not a good idea to push out a product with the same specification as your competitors, to be released at the same time, at the same price. The only differentiating marketing tool would be your company name. It would not make for a smart business decision.
There are differences in connections, 3d functionality, and contrast ratio to name the few that we are aware of so far. I highly doubt the differences will end there!

I do have to admit that it would be pretty funny if we suddenly had three LED projectors on the market that could produce 500 lumens, but they all had an identical noise level of 38db

2 of these stacked and cropped to 720p on RP screen is easily brighter 3d than 99% of H5360's on huge white screens.

for all sceptics who believe that 500lm is not enough for decent 3D - http://www.youtube.com/watch?v=YvGa93gMhSU
there is also second part of this vid that shows comparation 170 LED's lumens to 1000 UHP lumens.

He was comparing the 170 lumen LED to the Sony HS51a which is rated at 1,200 lumens but if you look at www.projectorreviews.com this projector puts out about 221 lumens. I have the Sony HS51a and it is WAY overrated in the lumens department and 221 sounds correct as it is very dim so the youtube review means nothing.

I don't understand, why not market one of these to the home theater market. It's a very simple design change. Add a bigger case and a bigger fan and the noise level drops.

Who cares how small these projectors are? It's like how thin manufactures can make a flat screen TV. I doubt many people are going to be taking these things from one location to another.

@mbw23air - yea, but still, it's pretty much enough bright light for 170lm. so, what do you think, can we get around the same amount of brightness using 3d shutter glasses on ~120" screen, projected by acer k330?

The qumi is getting good reports on brightness in the other thread but 500 lumens on a 120" screen with 3d glasses on might be pushing it. I guess it will just matter to you how acceptably bright it can be. It better be a high power screen at the very least and I would go smaller than 120". You might be better off with an Acer H5360 for added brightness. I can't wait for these 500 lumen LED's to show up as they might wind up being bright enough for all of us.

Assuming this measures anywhere close to 500 lumens, in a dark room it will fill a 120 inch screen no problem.


3d would be to dim for me, but some people might watch it. I would think it might cause a fair bit of eye strain.

Even worse, the Sony in the youtube has 1000+ hours on it, which means its lumens will be far less than the original calibrated lumens. My guess is that his Sony is actually putting out less than a 100 lumens.

No. If you look at the LCOS 3D projectors they are putting out far more than 500 lumens, and if you look at the > $3K Forum, the threads clearly suggest 1000 lumens is still too dark for a decent size image in 3D (and that was smaller than ~120"). But I guess I should state a proviso: YMMV.

The Acer K330 uses the new "Pico" chip from TI which is native 1280x800 pixels; I don't think TI even makes "wobulated" chips any longer, but i could be wrong on this point...
