Home Cinema What Is Home Cinema? If you've heard the phrase 'home cinema' mentioned on TV or in the press and are wondering what it means, then this guide will answer all your questions.
Both Plasma screens and projectors are suitable for home cinema use, but are both very different. Plasma screens offer a clearer image but can be more expensive that your home cinema projector. It's also worth noting that with a Plasma screen your restricted by size and location as they are usually a permanent fixture. Projectors on the other hand are very popular because they do create a "cinema" experience. If you would like
more information on Plasma screens make sure you visit our 'Plasma
Screen' section. There are a number
of factors to take into consideration when choosing a Projector for
home use, these are:- A projector's light
output is measured in units called ANSI lumens. The more lumens, the
brighter the image. Most projectors for home cinema need to be more than 700 lumens
for the curtains
closed or
1200 lumens
for daylight conditions. 'Keystoning'
is the name given to the effect on the projected
image when the projector
sits
below
or above the
centre of the
screen. Keystone correction counteracts this effect
by stretching the image at the bottom or top, resulting
in
a squarer, more
professional image. Until a few years ago projectors were mostly based on LCD technology, where the light from the lamp was filtered through red, blue and yellow LCD panels to produce a full colour image. Having three panels means that the projector casing needs to accommodate more room for the electronics, making the projector larger. Then Texas Instruments developed DLP technology. DLP converts light straight into a full colour image, allowing manufacturers to make much smaller projectors.
