Two separate brightness measurements can help you choose a projector that will display bright, colourful images in any lighting. Projector brightness is measured by lumens the higher the lumens, the brighter the projector will be at a given distance. LED:īulb can last up to 20,000 hours, better colour control than standard lamps, quiet operation and smaller footprint than projectors with standard lamps, since energy-efficient LEDs generally don't require a fan for cooling, widely used in pico projectors. No bulb replacement needed, considerably brighter than other light sources, better contrast than standard lamps, wider colour range than standard lamps, energy efficient. Standard lamp:īulb can last 3,000 to 4,000 hours (up to 5,000 hours in eco mode), Bright light output, Most affordable option Laser: Projectors are powered by one of three light sources: standard lamp, laser or LED (light-emitting diode). These types of projectors provide a combination of the benefits of DLP and LCD projectors, including a bright display, smooth video, and impressive colour saturation.

LCoS (liquid crystal on silicone) is a third type of projector technology, generally available only on high-end models. LCD advantages:īrighter output for use in well-lit rooms, Impressive colour brightness, Sharper images for detailed graphs and data presentations, Vibrant 3D images with no image ghosting, More energy efficient than DLP projectors, Slightly quieter than DLP projectors, Most LCD projectors include 3-chip LCD technology (3LCD) for even higher image quality. DLP advantages:Īllows for a lightweight and compact projector (especially for pico models), Portrays a film-like picture from DVD, Blu-ray and HDTV sources, Smooth motion for videos and fast-action scenes, Deeper, truer blacks than LCD projectors, High colour contrast, 3-chip DLP on premium models provides even higher image quality. While both types of projectors feature sharp image quality and accurate colour representation, each has its own advantages. Most projectors display images based on either DLP (digital light processing) or LCD (liquid crystal display) technology. Ultra compact and lightweight, easy to set up and use anywhere you go, smallest size available in a projector, extremely portable, ultra long lamp life Types of Projectors Small rooms, Small group presentations, Personal use at home or on the road Reasons to choose a Pico projector: However, you can compensate for ambient light by choosing a home theatre projector with high brightness and investing in a high-quality reflective screen to improve how the image is displayed even in partially or fully lit rooms.
COMPUTER PROJECTORS FOR POWERPOINT MOVIE
Because home theatre projectors simulate a dark movie theatre environment, they work best in a dedicated room where you can control the amount of light that enters from outside or from other areas in the house.

Home theatre projectors emphasize image quality and high contrast, with deep blacks and rich colour saturation. With images up to 36 times larger than a 50" class HDTV, a home theatre projector lets you scrutinize every play on the football field and jump right into the action in your favourite video games.
COMPUTER PROJECTORS FOR POWERPOINT TV
Although most projectors can handle any type of media, they generally do one thing best - whether that's entertainment-based content such as movies and TV shows, or data-based content such as spreadsheets and slideshows. To get the best picture possible - whether you're watching an HD movie at home or giving a PowerPoint presentation at work - you'll need the right type of projector for how you plan to use it. This indicates that there are 1920 dots horizontally across the display by 1200 lines of dots vertically, equaling 2,304,000 total dots that make up the image seen on the screen.

The resolution is indicated by a number combination such as 1920 x 1200. High resolution is important for projecting detailed charts and graphs, text, and high-definition video. Higher resolutions mean that more pixels are used to create the image, resulting in a crisper, cleaner image. Resolution is the number of dots or pixels used to display an image. For example, a 1000:1 contrast ratio means that the brightest white is 1000x brighter than the darkest black. If you take the brightest white on a screen and the darkest black and compare the luminosity, you get the contrast ratio. Contrast RatioĬontrast ratio is the difference between light and dark on a screen, expressed by a number. The brighter the projector the higher the lumen rating, and, all else being equal, the more it will likely cost. Projectors come in a wide range of brightness which are measured in lumens. Color Brightness and White Brightness (Lumens)
