InFocus IN3916 Interactive
Widescreen Short Throw Projector

Good data image quality. The image quality for data screens is easily good enough for almost any business or educational application. Green and yellow were a little dull in our tests, but yellow was truly yellow rather than mustard colored, and colors in general were suitably eye catching, even though they were a little short of vibrant.
Similarly, text was easily readable at sizes smaller than you're ever likely to use, with black text on white crisp and easily readable even at the smallest sizes we test with. White text on black was slightly less readable at small sizes, but it's also less common. The projector settings needed manual adjustment to eliminate pixel jitter from images that tend to bring out the problem, but even without the adjustment, jitter wasn't a serious issue.
The IN3916 even did reasonably well on brightness uniformity, which is often a problem for short throw projectors. We measured the uniformity at 67%, and could see brighter areas on solid white and solid black screens. However, adding almost any text or graphics to the screen broke up the image enough to make the lack of uniformity impossible to see.
Appropriately bright for a small- to mid-size room. Our test sample almost matched its 2700 lumen rating, but only with interactive mode turned off. We measured it in its brightest mode at 2539 lumens, or about 94% of its rating. With the interactive mode on, the brightest mode dropped to 2029 lumens. That's roughly 75% of the rating, but still bright enough for a small to mid-size conference room or classroom with typical ambient light.
With the interactive feature on, the presets ranged as low as 1072 lumens, which is still bright enough for a reasonably large image with low ambient light. Switching to eco mode drops the brightness by roughly 20 percent.
Better than par connectivity. The back panel of the IN3916 offers more than enough connectors for most purposes, including one HDMI 1.3 port for a computer or video source, two VGA inputs that can each connect to either a computer or a component video source, a composite video input, and one pass-through VGA port for a monitor. Audio connectors include a set of stereo RCA phono plugs and a stereo miniplug input, a miniplug for a microphone, and a miniplug stereo output. Menu settings let you pair any of the audio inputs to one or more image sources of your choice, so the audio source will automatically change when you change the image source.
You can also send data to the projector over a wired network, using the projector's LAN connector, or over a WiFi connection with an external $29 WiFi option, and can plug a memory key into the USB port to read JPG files. Finally, there's a second USB port to let you connect to your computer to use the interactive feature and an RS232 port for controlling the projector from a PC.
Better than par audio. The IN3916 audio suffers from a slight bottom-of-the-barrel echo effect, but no serious problems. Even better, the two 10-watt stereo Speakers are loud enough for a small to mid size conference room or classroom. For large classrooms, however, you'll want to use an external sound system.
Comes with annotation program.< The IN3916 should work with any annotation software, but InFocus ships it with Qwisdom WizTeach. The installation program lets you choose between having just those features meant for business use (primarily annotation and drawing tools), or educational tools as well including, for example, interactive maps that give the names for various countries and regions when you point to them.
