A full HD, 3D capable projector that
ticks all the right boxes
Projectors seem to fall into two distinct
categories: one for the business user, the other for the home cinema user. What
usually works well with one tends to fail with the other, with it being, most
of the time, down to a simple lack of connector, high noise levels or
resolution. However, the ViewSonic PJD7820HD projector ticks the boxes for both
business and home and laughs heartily at the competition.
The PJD7820HD is an impressive full HD
1080p DLP projector, which offers a list of outstanding features enough to make
other models pale into insignificance. The images projected are crisp, crystal
clear and can produce a maximum of definition. In addition, at 3000 lumens and
with a 15,000:1 contrast ratio, you'll find the image projected remains
high-quality even when the room is well lit, making it ideal for the modern
meeting room, or a living room for that matter.
Putting the image quality to one side for
the moment, the PJD7820HD is a surprisingly compact unit and one that's also
remarkably light. To the rear of the unit you'll find a decent mix of ports
ranging from the standard VGA to S-Video, HDMI, RS-232, mini-USB, audio-in and
-out and composite input. On top there are button controls for the on-screen
menu, selecting the source and the power, with the focus and zoom wheel toward
PJD7820HD surprised us in a number of ways.
Firstly, it was very quiet - one of the quietest projectors we've ever tested
if the truth be told. Secondly, it fired up almost instantly and auto-selected
the correct source, so we were watching the projected screen within a minute of
powering up both the source and projector. Another factor that put a smile on
our faces was the power-off time; it was, like the start-up, almost instantaneous.
No more hanging around for five minutes waiting for the lamp to cool down
before the fans shut down.

These points alone were enough to convince
us of ViewSonic's entry into the home cinema league, although these are also
factors that would greatly improve the business user's presentation. It's also
worth noting that the included remote control was of a decent build quality,
with solid buttons and a good range of use.
Moving back to the image quality, the
PJD7820HD integrates DLP Brilliant Color technology, bringing a vibrant, rich
picture performance with a much improved color depth and very good darker
shades. Moreover, the PJD7820HD also brings 3D to the table something we've
only seen so far in projectors of the $1,600-plus club. For those who have the
correct hardware, the 3D image projected is of a very good standard, although
it did tend to lessen in quality the maximum.
The lamp life is measured at around 5,000
hours for normal use, but ViewSonic has incorporated a DynamicEco technology
that will automatically adjust the lamp brightness to help prolong its life up
to an estimated 8,000 hours, and conserve up to 70% less power than normal.
In conclusion, the ViewSonic PJD7820HD is
an astonishingly good projector. The picture is as near as perfect as you could
wish for, and it's viewable even in well-lit environments. It's small, light
and can easily fill the post of home cinema projector or company presentation
projector. The only downside is the 2W internal speaker, which lacks any
You're in the market for a professional
projector, with an impressive list of features, then the PJD7820HD will,
without a doubt, fit the bill.
