Trade in digital projectors has become increasingly popular as their
affordability has meant that they are more widely used by schools,
universities, companies and even home owners. Their popularity is also down
to their varied range of applications which may range from training new
employees to presenting classes to children and of course entertainment
uses such as home theatres. The chances arfe that you are looking to
purchase a digital projector so that it can play a useful part in your
office or perhaps to replace your current television. Either way it is
important to know what factors to take into consideration before you go out
shopping as you will want to make sure that you are spending your money
If you are more of a technical novice then it is likely that you will only
have a superficial knowledge about digital projectors so here are a few of
the most important aspects to look out for. The first thing you need to
consider is the brightness of projector which you require. This will be
determined by the size of room in which it will be used as well as the
ambient light in the surroundings. The rule of thumb is that the larger the
room the more lumens (measure of brightness) you will need. A digital
projector with at least 1000 ANSI lumens should be a suitable start.
The next thing to look at is the digital projector’s colour contrast. This
will be especially important if you will be using your projector to watch
movies with in which case you will want there to be as high a colour
contrast as possible. However, if you are looking to use your projectors
for more mundane tasks such as business presentations then this wont be as
much of an issue so you will be able to save yourself some money and invest
in a projector with a lower contrast level.
Another consideration should be that of pixel density. The higher the
density the clearer your picture will be.
You may not be aware of the various types of projectors that are on the
market. DLP and LCD projectors are the most commonly found with each having its own advantages. DLP
projectors will be best used with video presentations on small portable
projectors as they are able to boost the overall brightness of the image.
This means that you will be able to buy a projector that is smaller in
size, however the picture quality will be compromised somewhat.
It is for this reason that LCD projectors tend to be the more popular
choice in terms of performance to cost ratio. The picture quality will be
much better as the resolution will be higher giving a much sharper image.
If you are looking to make sporadic use of a digital projector then you may
be a little put off by some of the prices. In the case where you are
intending to use a digital projector as a one off then you may wish to
approach an audio visual hire company which will help you to save a lot of money.
