The next step up from these, thin-and-light projectors, are as wide, deep, and bright as standard models but barely an inch thick, and they weigh in at about 4 pounds. They are highly portable, but you pay a premium for their svelteness, and they usually have a limited set of connection choices. The LG Minibeam LED projector is lightweight, but it doesn't sacrifice image quality.įinally, some standard projectors are still small and light enough to be easily portable, whether you're moving them between classrooms or taking them on a cross-country flight. Many come with soft carrying cases, but they could just as easily be slipped into a travel bag or backpack. Understanding Key Projector Specs: Brightness, Resolution, and Technology Although a few have internal batteries, the majority of standard projectors-as well as most thin and light ones-are limited to AC power. Pico projectors have low brightness (from less than 50 to up to several hundred ANSI lumens). They generally have low resolution, often 854 by 480 pixels (aka FWVGA or 480p), with a 16:9 widescreen aspect ratio. This combination limits their effective use to projecting onto a small screen in a darkened room, with optimal image sizes ranging from 24 to 48 inches, measured diagonally. If too much ambient light is introduced, or the image is enlarged too much, it will look washed out and detail will be lost.Īlthough a few palmtop projectors have a brightness of less than a hundred lumens, most fall in the range of 200 to 600 lumens. Some palmtops have 480p or lower resolution, and a few have resolutions up to 1080p (1,920 by 1,080), but most are 720p (1,280 by 720 pixels). #FASTFOX FULL HD MULTIMEDIA PROJECTOR REVIEW 480P# Their optimal image size tends to be between 36 and 60 inches, depending on their brightness and resolution. Slightly larger mini-projectors can have brightnesses of 1,000 lumens or more. ![]() Thin-and-lights and standard-sized portable models are often in the 3,000-lumen range, use standard projector screens, and can tolerate ambient light. #FASTFOX FULL HD MULTIMEDIA PROJECTOR REVIEW PORTABLE# We have seen a few small laser-based projectors and a smattering of liquid crystal on silicon (LCoS) models. However, the vast majority of pico, palmtop, and other small projectors are LED-based, and most use TI's Digital Light Processing (DLP) technology in their light engines.
