Best pico projector
The Optoma PK301 pico projector offers a bright, clear, beautifully color-balanced picture in a teeny-tiny package, reviewers write, though it is pricier than competing pico projectors. Focusing images is easy, and the PK301 offers many types of inputs, unusual among pico projectors. Like most, it lacks zoom control, so to make your picture larger or smaller, you'll end up moving the projector. For best results, especially when it comes to brightness, you'll want to use it plugged into both the wall and a laptop, though it technically requires neither. Sound is both tiny and tinny, a common problem for projectors this size, but the picture more than makes up for its drawbacks, reviewers say.
