Most of the projectors in this test are 720p HD models, so while most are capable of providing a satisfying picture, they lack the finer detail you get with true 1080p projectors. While some features varied, there were a number of similarities among the models. That would be a reasonable image size for a full-sized home-theater projector, but it pushed almost all of the compact projectors beyond their practical limit.

We also evaluated image quality on a 133-inch projector screen. We took color-temperature readings using the 65-inch screen. To test the projectors, we measured brightness capability at both 65- and 100-inch screens sizes, as well as at a 6-foot distance from a screen, which simulates a picture projected from the top of your bed to an 8-foot ceiling (just in case you want to emulate my wife and me). Like home theater models, these mini projectors need a darker environment you can't really see TV shows or movies in a brighter room, especially with larger screen sizes. That reduces brightness, thus limiting the size of an acceptable image. Because all of these projectors lack a zoom feature, to increase the size of the picture you have to move them farther from the screen. In our tests, which involved test patterns as well as TV shows and movies, the biggest differentiator was image brightness, which affects not only image quality but also the size of the image you want to present. In general, we found you get what you pay for, both in terms of image quality and features, though we did find a bargain in the bunch. Some have a built-in rechargeable battery for go-anywhere portability, while others require AC power. The Vankyo uses LCD technology, where light is sent through a prism and filters before hitting the lens.Īll the models except one come with a remote control, and a few have a carrying case that made toting them a bit easier. All of the models except one were DLP projectors-where the light is reflected off a chip with a vast array of tiny mirrors-so some people may notice 'rainbows,' or momentary flashes of colored light on certain dark scenes. Most were tabletop models, but there was also a micro-sized cube that fits in a pocket.Ĭompared with the full-sized models people install in home theaters, these smaller versions typically have fewer user controls and picture adjustments. The ones in our test ranged from about $120 to $450. Prices for these projectors can start below $100.

'But many offer decent brightness and picture quality, plus a level of portability that will let you take them almost anywhere.' 'These mini projectors are not necessarily intended to compete with full-sized home theater projectors,' says Claudio Ciacci, the TV-testing program leader at CR who oversaw the projector project.
