INTRO
Has the home video projector finally
arrived? We take an in-depth look at a new £800 LCD projector from Citizen, and
assess it's chances as an alternative to the traditional telly...
COPY
A couple of
years ago LCD video projectors were big news, there was even talk of them
taking a slice of the home cinema and big-screen TV markets; needless to say it
never happened. 'Domestic' LCD projectors are still far too expensive for
general home use, and the picture quality, though improving all the time, is
simply not that good, especially when compared with conventional large-screen
TV screen, or even CRT-based back-projection TVs. They're back in the news
again, though this time no-one is suggesting they're going to replace the big
box in the corner...
Two new
video projectors have recently appeared on the market, one from Marantz, the
other one from Citizen, which is the subject of this review. The most obvious
difference between the Citizen PC30 and those first generation LCD video projectors from Sharp and Sanyo is
size; this one is no larger than a couple of VHS cassettes stacked on top of
each other, yet it can throw up an image up to 50-inches across. The price has
come down in size as well, to just under £800, or almost half the price of some
earlier models.
LAYOUT
The only
thing that hasn't undergone any major change is the technology, the PC30 uses a
single LCD element, sandwiched between a projection lamp and a lens. The box
also contains a couple of circuit boards, a tiny fan and two miniature
speakers. Controls are confined to an on/off switch, and three buttons to
control brightness and volume; relative levels are shown on a simple on-screen
graphical display. Power comes from a plug-in mains adaptor, which is included
with the outfit, along with a soft carry case. There's a row of three phono
sockets on the back, one for composite video, the other two are line inputs for
stereo audio. On the underside there's a tiny switch, to select between PAL or
SECAM operation.
The PC30's
LCD element is only one inch across, it uses a 170k pixel (picture element)
display, which in definition terms -- i.e. its ability to resolve fine
detail -- puts it somewhere between the
better camcorder colour viewfinders and 2-3-inch pocket TVs, though the number
of pixels is only one of a number of factors that influence image quality.
Picture size and brightness are equally important and they're largely governed
by the strength of the projector lamp. The PC30 uses a 35 watt halogen bulb and
reflector, and it looks suspiciously like one used in a number of video lights.
The bulbs have a life expectancy of between 300 and 400 hours and can be
replaced by the user. The cost of replacement bulbs have still to be fixed but
Citizen expect them to sell for around £6.50.
PERFORMANCE
As
projector lamps go 35 watts isn't especially powerful, and when Citizen talk
about the PC30 producing an image 50-inches across they're being a little
optimistic and should also say that the picture will only be visible at that size
if it's shown on a high-efficiency projection screen, in total darkness.
Reducing the picture size helps a lot and a 20-inch image is viewable in a
dimly-lit room. At that size the picture looks quite reasonable, colours are
bright and fairly well-defined; our sample was able to resolve 230-lines from a
static test pattern. Granularity or pixellation was evident, though, and this
increases with image size; it's not unfair to say that pictures over 30-inches
or so across look as though they're being seen through a tea-strainer, though
this wouldn't necessarily be a problem if, for example, it was displaying
simple graphics.
Sound
quality is quite tinny, but that's to be expected with such small speakers,
quite frankly we're impressed that it has on-board sound at all.
VERDICT
The big
question has to be who would want a pocket-size LCD projector costing £800,
that produces inferior picture and sound to TVs costing a quarter as much, and
can only be used in near-dark conditions? Picture size is the obvious advantage
this device has over conventional video displays. We can see the PC30 being
quite successful as a low-cost AV presentation tool, for commercial,
industrial, educational and club users, showing video material to small
audiences on a 30 to 40-inch screen. Portability is another key feature, and it
could prove popular with camcorder-owning campers, caravanners and boat owners,
though Citizen should seriously consider including a 12 volt power cord and TV
tuner in their accessory list. We're still some way away from a viable domestic
video projector, but the PC30 brings it one a little closer and in another two
years, who knows?.
