Projectors Reviews, price and comparision

While the most micro projector try makers these days, so many ports for different connections sources as possible in their products small frames fit, Acer has the opposite tack with his C120 projectors ($ 299.99 list). This Pico Projector via USB connected - and USB alone - emulate what's on your computer screen on a computer. In this respect is similar to it have some budget projectors, the we, like the 15 lumens Ray Lite ($159 direct, 3 stars seen), but the Acer is much brighter and easier to set up (but not necessarily to run).

The C120 is a LED-based DLP projector with a native resolution of WVGA (854 by 480). Its rated brightness is 100 lumens, the it brings in your Pocket projector elite. The only other 100 lumens have Pico Projector that we reviewed is the Optoma Pico PK320 Pocket projector ($ 450 Street, 3 stars).

The C120 is a nice tiny projector, black (shiny at the top) and rectangular with round corners. It fits in my pocket, but just barely. I weighed it on our postage scale at 6 ounces; Add the power supply brought the total weight up to only 13 ounces. The wheel is the focus on the page next to the lens, I find it front of the lens, at least for the prevention of disability with a stray finger preferred optical path. The wheel is very small, and I found it hard, bring precise focus of the image.

Optoma PK320 offers a much wider range of connectivity options, including HDMI, VGA and composite video. It can run also presentations from internal memory, a micro SD card or USB stick.

Installation and operation
The projector can be operated via an AC adapter or USB port of a computer. It comes with a USB cable, which to the projector with a USB 3.0 port connected. It is a Y-cable with 2 x USB type-B connector for the computer, so that you can run power and data over the wire. You take a hit in brightness when it makes the projector over the USB cable.

When you close the C120 USB port on the computer, the projector installs a driver on your system. You have to agree to the installation by clicking on the appropriate button in a popup window each time, when you use the projector. I have the projector with 3 laptops, and was able, run it on all three. But for one of them, I could just run some time, and not in a position to determine why it does not work consistently. Also, regardless of what laptop I used seemed fussy the USB connection and was sometimes lost. Stripping and that re plugged the cables in this largely resolved.

If I were to install the driver, it would the laptop screen to 800 x 600 pixels, size closer to the resolution of the projector. You can then size; the screen through the Windows Control Panel the projector supports resolutions of up to 1,280 by 800 and okay at this resolution, but the image looked better in the lower resolution.

Test
The projector threw a picture about 6 feet diagonal to our test screen of about 8 metres. Although it saw in order, in the darkness, it was adversely affected with modest ambient light, so I have most of the tests with the image size approx. 4 M diagonal.

I found the C120 image quality good for internal presentations (e.g. small working groups). You could it presentations in an emergency for street if you can verify that it easily connects to your laptop via USB - in this projector USB is the only game in town. Colors seemed pretty true; There were references to the rainbow effect for DLP projectors where bright areas against dark backgrounds in small blue-green rainbow can break. Focus seemed somewhat soft, and text was not very sharp. Video quality was okay for short clips as part of a presentation.

An only-USB Pico Projector - and as such, the C120 is unusually bright - offers the advantage of the low price and - at least in theory - easy installation and operation. Disadvantages are that it is not as versatile as a fully functional model such as the Optoma PK320, and it is a one-trick pony - if you have problems connecting via USB, you have no other options. (If the C120 driver is not loaded, restart of the laptop will sometimes solve it - although you would not want to do, if you are time pressed and have presented on the road to a small group.) You want not the USB Y-cable, set are not as simple as cable USB 3.0 plug, as to find the previous cables.

If USB connectivity is everything what you are looking for in a pico projector, the Acer C120 can your model of choice. It is significantly brighter than the ray Lite and other USB only viewers, those which we have looked at and less expensive than fuller recommended models.
