Ideal for screening sport matches for large audiences
Used to project a set of images onto a large screen, television projectors are useful for screening sport matches for large audiences, home cinemas and business presentations. Projectors offer the luxury of creating seamless sequences of images with enormous clarity while expressing intense color and visual detail.
There is a huge list of brand names from which to choose before purchasing a TV projector. Panasonic projectors, Epson projectors, Sony projectors, Toshiba projectors and InFocus projectors are the most popular.
A major criterion for choosing projectors should be the quality of the resolution you wish for which is dependant on your budget and whether you are a buying for commercial or home cinema use. Higher resolution and greater contrast of color would be more important for a presentation rather than for pleasure use at home. Resolution is simply the number of elements or pixels which form the picture. The higher the resolution, the more elements there are and the closer they stick together creating a greater clarity of picture. Resolution is measured in ANSI Lumens.
The type of resolution is indicated by two groups of numbers usually in the hundreds. These numbers represent the number of particles measured vertically and horizontally across the screen. Lower resolutions are satisfactorily bright and unless you need intricate details in your images, this would lower the cost of the projector. The grades of resolution are defined by SVGA XGA SXGA and UKGA, the latter being the highest resolution and the former being the most popular and cost effective choice.
Different brands specialize in different projects: to buy an LCD projector, the best are Epson, projectors, Sanyo projectors, Hitachi projectors and , Sony projectors and Sharp projectors and now the latter make is expanding into DLP projectors. There are various types of projectors which are suitable for different applications. LCD projectors are designed for demonstrating "PowerPoint" material such as graphical material such as pie charts and spread sheets. For showing DVDs and videos, DLP projectors are more suitable however this is not to say they can not perform for presentations.
LCD's are more efficient as they transform more energy in to light but if you are in a dark room, any level of ANSI Lumen rate will be satisfactory. DLP's use spinning color wheels which boost the deepness of color giving dramatic images. The draw back to this is some viewers are able to see the rainbow effect which are excess colors from the spinning wheel of blue, green and red which interferes with the picture.
The flaws in LCD cinematic projecting are a slightly fuzzier picture caused by larger spaces between the pixels. Color saturation in LCDs is not as extreme as in DLP's resulting in a less dramatic picture.
