There are essentially two main categories of projectors available in the
market; the DLP’s needed for business and teaching presentations and
projectors for LCD screens. The following buying guide will help you chose
the right projector in both categories.
If you are planning to buy a DLP projector, a resolution of 1024×768 XGA or
more would be ideal. You should make sure that projector is compact and
easy to carry around. Do take the projection area into account as well
before deciding on a projector. If the area is large you’ll need a
projector with more lumens (2000 and above). Finally, you must ensure that
the projector is user friendly. VGA inputs, a remote control, built in
mouse capabilities and laser pointers are some of the essential features.
For DLP projectors you will also need screens (though you can project on a
white wall, the screen would offer a better output). The size of the screen
should depend on the viewing area available with you.
Before buying an LCD projector you must check for the following essential
The contrast ratio- A good contrast ratio is a must for sharp and clear
video images. Ideally a projector should have a contrast ratio of at least
Color- For real life video images your projector must support a huge number
of colors, 16 million or more would be ideal.
Brightness- You will need to adjust the brightness according to the light
available in your viewing area, however, do make sure that your projector
offers at least 1000 lumes.
Resolution- A good resolution means sharp images. A resolution or 1024×768
or more would be ideal for an LCD projector.
Compatibility- Your projector must be compatible with the video standard
(such as NTSE, PAL, and SECAM) you require.
User friendliness- A remote control, built in speakers along with option of
attaching external speakers, light weight and well labeled input panel, are
some of the essential features of a user friendly projector.
Apart from the projector you will also need certain essential accessories
like mounting kits, projector lamps, document camera and writing rolls (for
presentations) etc. You can purchase these accessories based on your needs
