Some Important Points to Consider When You Buy a Projector
When setting out to buy a projector today, it is highly unlikely that the buyer is planning to project holiday slides or to show 16-mm home movies. Equipment of this nature is almost obsolete in most countries and is most likely to be found in the windows of second-hand shops or in museums. Now more than half a century into the digital age, there is virtually no aspect of communications and audio-visual technology that has not been replaced, or in some way enhanced, by the many benefits inherent in these strings of zeroes and ones.
Even at the local movie house, the latest Hollywood releases are now stored as compact, digitised files on hard drives and other mobile storage devices, rather than on vast lengths of celluloid film. Today, when you decide to buy a projector, it will not be equipped with motorised reels and sprockets. Instead it will access the audio-visual material stored on another digital device, such as a laptop, tablet PC, USB storage device, or a smartphone, and may even stream it directly from the Internet. While this may make the modern devices appear infinitely versatile, they do have their limitations. It is therefore important to check for these when it’s time to make your selection.
One particularly important preliminary is to consider how your device is going to be used. Whereas business use tends to be limited to more static displays, such as PowerPoint presentations and pie-charts, in the home it is more likely to be used to show movies or to play games, and will need higher performance characteristics than when delivering business presentations is the main reason one may wish to buy a projector.
Perhaps the next question to ask yourself is whether or not you are likely to want to use it outdoors. If this is a possibility, then your machine must be able to generate a sufficiently bright beam to cancel interference that may be caused by ambient light and so as to ensure it will render a clear, high-contrast image on the screen.
As far as technical specifications go, zoom range, aspect ratio, and resolution are perhaps the most crucial to get right, but the underlying projection technology, currently digital light processing (DLP), liquid crystal display (LCD), or liquid crystal on silicon (LCoS), should also be considered. DLP is cheap, but moving parts make it a little more fragile and prone to the “rainbow effect”. LCD models are more reliable but heavy. While superior, LCoS machines are a bit pricey.
Zoom range can be critical when you buy a projector, as this determines the length over which a clear image can be projected and must suit the length of the room in which it is to be used. Most of today’s models comply with the 16:9 aspect ratio shared by HDTV, widescreen DVDs, and Blu-ray discs, while resolution is only critical for HD movies and gaming.
Last but not least of the considerations is connectivity. While VGA ports are standard, HDMI, USB, and Wi-Fi support may vary, so be sure to cater for all devices you may want to connect with.
