I'm an Audio/Visuals tech and I deal with meeting room projectors all the time.

This projector isn't suitable for much and I'll go as far and say it's a waste if money.

2000 lumens is the absolute minimum a projector should be since at that lumen output, the room has to be pretty dim to be able to see what's on the screen.

And believe it or not, A/V projectors are barely transitioning screen resolutions from 1024x768 to what they are now. Usually 1280x800. Any other resolution besides that gets scaled to fit.

Pico projectors were all the rage a couple of years ago but they haven't took off at all. In all my years of doing Meeting A/V, I've only seen someone use a Pico projector once. This Acer projector is just a slightly larger Pico projector. The idea is great but the pitiful 500 lumens output is a big strain on the eyes.

1280*800?! That's a failure right there.

What does it mean when it says that it supports 3d images? If it can project them by itself then I protest its pathetically low resolution.

500 lumens is pathetic. I have 2400 lumens of LED lighting going on in the room I'm in right now and it isn't enough to truly illuminate the room without the aid of natural lighting (and it's a rather small room).

Damn dude. Relax.

I don't know that I'd call it a failure or pathetic. It's a 4x5 HD projector (720p is HD, whether you agree or not) with a 30,000 hour lamp at under $500. This is pretty respectable.

This will serve a great many applications, and it's an encouraging step forward.

Clearly you're not the target customer, nor am I. My applications require something substantially brighter too.

Who has a need for this? What "great many applications" will it serve?

How is this a step _forward_? It's a projector with a resolution from yester-year stuffed in a tiny box and given the light output of a dollar store flashlight.

With its lack of lumens I have to wonder why it has 3d support as the 3d glasses will make the image even dimmer. When a projector has less light output than a common, everyday incandescent bulb something is wrong.

I don't work for Acer and I'm not trying to sell one of these to you. If it doesn't meet your needs, move on.

People that design, market, and sell projectors for a living evaluated this as a worthwile and marketable design. Apparently without consulting with you. They'll likely not make this mistake again.

Yea, but considering the size those specs are pretty good. It gives me much hope for the eventual useful integration of projectors with smart phones.

Native resolution is 1280x800. 1080i source will be downscaled to 720p. Technically HD, but not what many would think.

500 Lumens is not very bright. This is not a Home Theater or Home Entertainment projector by any stretch. Max image size is 80 inches, and would likely require a very dark room.

Dongles required for any input other than HDMI is somewhat limiting.

Yes, it's small. May fit some needs. But I'd not be expecting to host an effective Outdoor Movie night with this.

Yeah, but they're also cramming HD displays onto 5" phone screens. You don't see anyone trying to make a presentation on those. It's not enough to just give the resolution of the projector, because it's useless if it can't make anything bigger than a 5" image. So, how big of an image does it support? I realize that projected images become larger the further the projector is from the surface. But there is a point at which the image washes out or becomes distorted. So, what is the practical image size this projector supports?

Projection Screen Size - 17 (43cm) to 100 (254cm)
Projection Distance - 1.8' (0.6m) 10.6' (3.2m) Throw Ratio - 62 @ 2m (1.50 - 1)

So, it's the real deal. Shame that the WiDi is only provided through a dongle, but otherwise pretty sweet looking.
