Small classroom projectors that can be easily carried from room to room as needed no longer have to sacrifice brightness for portability. Regardless of whether it creates its image with tiny LCD screens or a DLP engine, the latest crop of projectors pump out the photons, have sharp focus and are surprisingly affordable. Here’re three of my favorites.
BenQ’s MP624 squeezes a digital light processing (DLP) chip that puts out 3,000 lumens of brightness on a screen into a 5 pound package. With pinpoint sharp XGA resolution, the projector’s inputs include a computer connection, plus S-Video, composite, component and HDMI jacks. Look for it in the coming weeks at $600.
Easily the brightness king, InFocus’s IN13104EP can put an astounding 3,500 lumens on a screen or blackboard so that the lights never need to be turned off for a lesson. The projector creates XGA images and has a mini-USB plug so that it connects quickly and accurately with a notebook. The projector weighs 7 pounds and sells for $1,700.
At 6.4 pounds, Sanyo’s PLC-XW57 is right in the middle but can still pump out 2,000 lumens in XGA resolution, making it good enough for lights-on lessons. A big step forward for classroom projectors, the PLC-XW57 has Sanyo’s 3D Automatic Uniformity Correction Control, which makes sure that the image doesn’t have the hot spots that we’ve all seen. The projector sells for $895.
