This opens up a range of options for renters and homeowners who are able to make modifications, with plenty of options available for just about any room. You can store some of these in a drawer then pop them on a table for occasional movie nights, while others are suitable for ceiling mounting. The reason for the wide variety in price is the technology used and the brightness of the projected image. This is a very broad category that covers temporary general use setups to basic home theatre installations. Wireless connectivity is standard for this sort of device because you're just as likely to be casting the video from your phone as playing it from a Blu-ray player. Prices start at a few hundred dollars and can deliver a surprisingly bright picture, if you're watching the video in a very dark room. They're good for playing family videos or watching a movie with friends, as long as you don't have cinematic expectations. They're often no bigger than a smartphone, with most including a built-in battery and basic A/V inputs and outputs so you can connect a laptop and Bluetooth speaker, for example. Mini ($100–900)Īlso known as 'pocket,' 'portable' and 'pico' projectors, these focus on convenience. There are three main types of projectors. whether the projector is going to be a permanent fixture or only rolled out for movie nights.the amount of natural and ambient light in the room.These points can help you figure out which projector will suit your needs. The best way to find out if this will be a problem for you is to look at a DLP projector in action, pick a high-contrast scene, and quickly look from one end of the screen to the other. However, not everyone will notice this effect. Light is filtered onto the mirrors through a colour wheel to produce alternating red, green and blue screens thousands of times a second, producing the final projected colour image.ĭLP projectors using a single chip have been known to produce a 'rainbow effect', a potentially distracting trail of red, green and blue after-images that is particularly visible on high-contrast scenes. Generally, the more mirrors used, the greater the resolution of the projected image. This can make the picture appear as if you're looking at it though a very fine mesh screen and can be particularly noticeable in large flat areas of light colour.ĭ igital light processing (DLP) technology uses minuscule mirrors set out in a matrix on a semiconductor chip, known as a digital micromirror device (DMD). Some LCD projectors have been known to produce a 'screen door effect', with fine lines in the projected image that are visible to some people. Liquid crystal display (LCD) projectors generally use three transparent LCD panels – one each for red, green, and blue – which let individual pixels be turned on or off as the light passes through to make up the projected picture.
