Acer K330 1280x800 WXGA 500 Lumens LED Light Sourced DLP Home Theater Projector w/SD Card Reader & Mini USB Port

Pros: Large picture for relatively short throw.. 100+ inches from about 13 feet.
Super long bulb life (advertised as such, at least)
Small.. lightweight
Quick on/off as compared to my old optoma.
Pretty good picture.
1080p capable.
I don't see full on double rainbows.

Cons: Slightly louder fan than previous projector.
Very few size adjustment options.. no zoom.. horizontal/vertical shifting... So there's no margin of error in placement.
More picture adjustment needed than I was used to.
slightly dimmer than the old "lamp" projector, but not as noticeable as I thought it'd be.
I'm finding it difficult to get a happy medium between movies/media and regular computer output - the focus is pretty sensitive.

Other Thoughts: Overall I'm happy with the purchase. And I believe it will work well for my home theater video device.
It's Nice to have the peace of mind to not have to worry about the bulb. Not blown away as compared to the projector I've been rockin' since 2009, but it does seem to be an improvement.
Was looking forward to playing with 3d on this guy, but realized my receiver isn't HDMI 1.4a compatible.. and I don't really feel like forking out 200 bucks to switch to Nvidia.. Plus the cost of the "vision kit" (I realize there are AMD options available.. but.....)
I'm sure this resolve won't last too long..

Pros: -portable - not as small as a pa60g at nearly same specs
-bright under low ambient light
-great 3d using cheap dlp glasses - acer5360 inf allows 720p 120Mhz over hdmi and vga
-has an audio out port. this was why i left out the ml500 as a choice
-includes a lens cover
-uses standard power supply cable (easily find a new one if you need)
-20,000 hour bulb life... i'll never need to change it!
-94" (16:9) display with low ambient and 3d was still very usable
-got it on sale for $100 less than the pa60g (though i still wish i had one, they're so tiny to be so bright!)

Cons: -fan noise - even on eco it's louder than the qumi on full blast. it's about as loud as an old school hsf using a 30mm delta fan. the drone fades out while you watch movies as your focus shifts. it's not as high pitched as the old 46db fans but still pretty loud. eco mode makes it a bit quiter with no noticeable quality loss. no eco mode in 3d however. on 3d it's louder than normal mode.
-focusing is a bit of a chore. small movements are needed to focus and it takes a few back and forth turns to get it right - plus (on mine) the top and bottom are slightly off when focusing

Other Thoughts: great mobile theater. got a dock form my galaxy note 10.1 and hook it up to the PJ with ease. since the gn10.1 can handle just about all formats it's a great little companion for the PJ. getting an mhl adapter for my gnII would be great too. i'm surprized how well 3d works. using stereoscopic player and the acer inf file i can do 3d at 720p over hdmi and vga. without the inf 3d works only over vga at 1024x768 - which wasn't too bad either.

all in all i do not regret my purchase. still having some nagging thoughts to still get the pa60g for extra portability. i just can't find enough reviews about it yet though.

Pros: Low power consumption; bulb longevity

Cons: low lumens; small size makes it difficult to mount to a traditional ceiling mount and discredits it as a home theater projector

Other Thoughts: The fantastic contrast makes the low lumens a non-issue in dimly lit rooms or rooms without windows (any home theater room); excellent 720p display at a low cost up front and long term with its bulb longevity and low power consumption; I have it paired with 60"x40" art foam board screen ($15 hobby lobby) painted with ProClassic Smooth Enamel Satin Finish Extra White (Sherrill Williams) in a room with a little sunlight bleed-in and it works great.

Pros: Compact size, Easy to set up, Great picture, Extemely cost effective.

Cons: No lens shift, remote is just too small, being so light you will have to make sure that your power cord and any other cords that you connect are fixed to something because they will pull it off of whatever you sit it on.

Other Thoughts: When I went searching for an affordable home theater projector I was knd of skeptical about the 500 ansi lumens. But, I took the plunge anyway and all that remains is the oooohs and aaaaahs! My wife said that I wouldn't like it, that it was a waste of money. After i set it up and was watching a HD movie, she came in the room and her eyes opened wide and she said a bad word and then said how wrong she was. The picture is awesome! I have it at approximately 100" diagonal and I am sitting about 12' away and the room is dark and the picture is soooo awesome. And this is right out of the box, on a painted wall, which is kinda grungy since it hasn't been painted in over 20 years. Maybe that's why the picture is so good.LOL I can't wait to see what it will look like when I acrually put a fresh coat of paint. I am so glad I decided to go with this particular model.

Pros: Color reproduction is very well balanced. Great for daily HDTV usage and excellent bluray performance. Works well with 120" Elite screen Amazingly!

Cons: Terrible support for 3d out of box, but this is just politics however. Projector produces a good 3d experience with 3d bluray and 3dvision with a nvidia gpu equipped pc, and if you hack your system to override the edid with the h5360's. Acer and Nvidia need to release a firmware update to correct the flaws in the current edid. Stock EDID disables this units real potential. Another flaw with the K330 is the usage of plastic optics that suffer from heat expansion, this presents itself as a focus shift that occurs after the unit has reached normal operating temperature, adjust focus after approximately 15 minutes of operation to correct for this.

Other Thoughts: Good projector really. I like it better than my 2500 lumen casio xjm-240. Much better color, Reds are equal to blue and green unlike the xj's preference to greens and blues.
Success with getting 3D bluray and 3d vision to work after h5360 edid override.

Pros: Great Projector. I used and painted my wall with Behr silver screen paint and the picture measured 100" across, not diagonal. Used my receiver as the HDMI switch as the projector only has one and my receiver has 4. Cable box, Xbox360, Sony 3D Bluray player and HTPC all look fantastic.

Cons: Wish the lumens has more than what it have. Remote is like one of those from knock off brands, c'mon Acer don't pull your level down just to squeeze a few more cents from your customers, we will know. It's embarrassing. Fan noise but with my home theater crank up, it not noticeable. Built in speaker makes you wish Acer didn't put it there in the first place

Other Thoughts: My first LED projector. Painted my wall with Behr Silverscreen paint from HomeDep for about $12.75 a quart which is more than enough for the 100 inches screen wall and the result was outstanding. Its not as sharp as my 60" LCD TV but this projector has no pixel, color saturation is great and it project an image just like in the theater. Football is like I'm just besides the players and coupled with my Home theater, everything is insane. I'm never going back to traditional TV. Can't wait for the 2nd gen LED projectors to have their lumens doubled.

Pros: The picture is clear enough for me. I'm running at 67" on my wall writing this review. Response is great, tv & movies & youtube look great. Even with the sun bleeding in I can see it during the day, not as well as at night obviously but it's perfectly fine.

Cons: I wish the resolution was a tad higher, but it's plenty for me.

Other Thoughts: I wish this was the first display device I ever had.

Pros: great Lighting: even with the lights on in the room I can still watch a movie.
Plays Blue Ray movies with the PS3 attached no problem.
Good lighting output even in Econo mode if your in a dark room.

Cons: SD card slot works with Videos, even works with the Blue ray format, barely, but probably because I had the highest setting on my camera. Larger videos on an SD card are bad but it will read them

Laptop HDMI has size issues, cuts off the outside 4 edges of the desktop. it might be a setting I havent found yet.

Other Thoughts: I have owned a Projector in the past that had 3,000 Lumens, and was worried about the 300 on this one... after playing with it in different lighting settings I am happy with this one and will probably pick up another one.

Suggest running most items through the HDMI slot.

Pros: The brightness is decent, although not quite as good as I expected.
The size is relatively small.

Cons: Fan noise starts out okay, then shifts significantly louder when the unit heats up a bit -- enough that if I could return it I would. I don't really understand why it has much need for a fan at all. I have other LED projectors, one of them has no fan, on the other the noise is not noticeable.

Also, the menu navigation using the buttons on the projector itself are poorly designed. I prefer a projector that I can control from the unit itself just in case I misplace the remote. I plugged in a USB memory stick with a properly formatted video on it, and after some trial and error was able to see that the video was available, but I couldn't get it to play using any of the buttons on the unit -- only with the remote.

The contrast is not good at all. If you take the brightness over 50 you lose black right away, which is not corrected at all by having the contrast higher.

Other Thoughts: This is a big disappointment. I have two other LED projectors, and this one just doesn't measure up. I am stuck with a projector that I'm not happy with.

Pros: I was looking for a HD projector that would not use alot of power yet have most of the features. I have been researching them for over a year and the K330 fits the bill. Low power consumption for hours of game play on a console. HD picture is great overall. did not notice the rainbow affect. it has a small foot print yet at roughly 8-10ft i have over 100" pic. it has different pic modes for bright and econo. overall im am very please with it and the fact its portable and quiet are a huge plus. Overall a great buy.

Cons: the speakers are kinda cheezy. the acer screen gets annoying when going through ps3 screens-till i find a way to disable it.
