The past year has brought many changes in the world of video
projection. From lower-priced projectors to longer-lasting lamps, the latest
technologies should put more of these machines into the hands of those spreading
the Good Word.
1. High-Resolution Projectors for Less Than $1,000
Two years ago, we saw the first video projector (InFocus’
X1) drop below the $1,000 mark. These low-priced projectors were
typically SVGA (800 x 600) resolution, and ranged in brightness from 1,000 to
1,500 lumens. The price reduction helped keep SVGA projectors among the most
But time marches on, and now you’ll find SVGA projectors for
less than $700, and XGA 2,000- lumen projectors selling for less than
$1,000.These price drops are great news for growing churches on tight budgets.
High-resolution home-theater projectors are also getting less
expensive. Native high-definition signals are now commonplace and can be bought
for as little as $999. (Check out the Sanyo Z2 LCD projector from
www.projectorpeople.com.) Portable projectors are a great option for youth
groups and family movie nights. The high-definition, native-widescreen resolution
will also make your purchase more future-proof, which might spare additional
expense to your church in the next few years.
2. More Brightness for Your Buck
As high-resolution becomes more affordable, so do
higher-brightness projectors. In the past, church leaders aimed to fit an XGA,
2000-lumen projector into their budgets.
Today, with established budgets, churches can afford to
purchase 3,000- to 4,500-lumen projectors for the same price. This allows
medium-size churches to buy brighter systems, which might also allow for larger
screen sizes. Churches that might have been priced out of a projection system
(limited by large amounts of ambient light) will now find it much more
affordable to go that direction.
3. Longer-Lasting Lamps
Projector lamps have nearly doubled in lamp life on average
over the past two years. This is partly thanks to improvements in cooling
systems. Manufacturers are specifying longer-lasting lamps (as much as 5,000
hours) and are even increasing the lengths of their lamp warranties. Expect to
see more manufacturers offering at least six-month/ 1,000-hour warranties in the
coming year. Mitsubishi offers a one-year/1,000-hour lamp warranty on new
projectors — significantly better than the manufacturer’s own previous
4. Economy Modes Have Become Standard
An economy mode is now available on most current projector
models. This handy feature allows you to extend lamp life and lower fan-noise
levels, with slightly lower brightness. In some cases, the lower lumen output is
a useful feature as well.
As projectors get brighter, there are some applications in
which the brightest setting might actually detract from the picture, washing out
black and other dark colors. This occasionally happens in home-theater
environments, where lighting is completely controlled.
5. Filterless Projectors
A great benefit to projector owners who use ceiling-mounted
models, new filterless projectors make scheduled filter cleaning unnecessary.
Sealed optical systems allow manufacturers (like Mitsubishi) to eliminate
filters from their designs altogether.
Previously, filter cleaning was the one regularly scheduled
maintenance required for a projector. It was often overlooked because projectors
were hard to reach, or it was simply forgotten. Filterless projectors are a
great option for churches who intend to ceiling-mount their projectors in
difficult-to-reach locations such as sanctuary ceilings.
6. DVI Cables Run Longer
Special boosters and improved internal parts have allowed DVI
cables to run longer than they used to — now up to 100 feet. This is good news
for those who have installed new projectors but have been unable to take
advantage of digital video quality because cable runs were too long. DVI cable runs more than 25 feet will need a distribution
7. 802.11G Wireless Support
The new, faster wireless standard — 802.11g — is now
available on select wireless video projectors. The higher bandwidth makes for speedier transitions, fewer
artifacts, and more power to run applications such as PC video.
Some manufacturers have also designed external wireless
products with an 802.11a standard. There are external wireless solutions that
allow you to project wireless mpeg video and standard NTSC television
broadcasts. However, wireless high-definition video still isn’t a viable
8. Higher-Resolution Projectors on the Way?
It seems a logical next step to increase projector resolutions
to match the outputs of today’s higher-resolution laptop computers.
Manufacturers and resellers often instruct buyers to match their projectors to
that of their computers; however, projector technology hasn’t kept pace with
the changes in laptop resolution.
Currently, the highest-resolution LCD projectors are SXGA
(1280 x 1024) and QXGA (2048 x 1536). Widescreen formats include WXGA-H (1280 x 720) and WUXGA (1920
x 1200). These ultra-high-resolution projectors cost significantly more ($4,000
or more) and aren’t expected to fall into a lower price category for some
Higher-resolution projection systems beyond XGA (1024×768)
aren’t crucial for applications such as PowerPoint, or entertainment
applications such as playing DVDs — churches’ primary uses for projection
9. Do-It-Yourself Installation Assistance
has become much more
common in the past year, with many more manufacturers including it on their
home-theater and installation products. Lens shift is a function that allows for
easier positioning of your projector in installed environments. Some projectors
provide room to move the lens left, right, up and down within the housing.
Using lens shift will produce better results than using
digital keystone correction because it maintains the integrity of the original
image rather than compressing the pixels to square the image.
allows you to make a
larger image from a given distance, without physically moving the projector or
sacrificing image quality. As easy to use as a zoom lens on a camera, the
optical zoom usually is just a turn of the lens or a press of a button.
Projectors have varying degrees of zoom capabilities. Some can
nearly double the size of your image. Optical zoom is listed in the projector
specs as a number such as 2x, or “two times,” for double the image size from
the same distance.
This feature might also allow you to use shorter cables,
meaning less signal degradation and a lower cable cost.
Most projectors have an offset lens rather than a centered
That means when planning where to hang your
projector mount, you must account for the degree of offset rather than just
centering the mount based on room specifications. A projector with a centered
lens takes this extra equation out of the picture for easier installation.
A Distributor’s Wish List
Based on our interactions with customers, here are a few hopes
for future projection technologies:
- Seamless wireless video (built-in or external solution)
- Battery-powered portable projectors
- Self-masking chips, or lenses which
adjust to eliminate black bars in non-native format
- Greater zoom capability
on more models for greater flexibility in installation or portable use
bayonet-style lenses for more pre- and post-installation flexibility
- Competitive pricing on RF remotes for electric screens
