ViewSonic PJD7820HD review - HD projector good for business

£720 inc VAT

Manufacturer: ViewSonic

Our Rating: We rate this 4.5 out of 5

The ViewSonic PJD7820HD is a high-definition projector that will do a great job in any office's meeting room. Here's our ViewSonic PJD7820HD review.

ViewSonic projector

Aimed at businesses that need to be able to project vibrant images in meeting- or conference rooms, the ViewSonic PJD7820HD projector looks like a business bargain at just £720, thanks to its full-HD resolution and outstanding specfications list. See also Group test: what's the best projector? 

Keen not to restrict its target audience, ViewSonic also believes the ViewSonic PJD7820HD projector will work effectively in home cinema. However, we'd suggest that the brightness rating of 3000 ANSI lumens is a little too much for the home.

That figure does make it rather good in a light-filled conference room, though, and the ViewSonic PJD7820HD will project a clear image in almost any conditions.

Another asset is the short-throw lens, which lets the ViewSonic PJD7820HD beam a 72in picture from a distance of just 2m. This makes it handy for compact meeting rooms, where space is sometimes an issue.

The ViewSonic PJD7820HD projector itself is rather smaller than the typical full-size model, and fits easily onto most desks. The glossy black casing gives it a more polished look than the average business model, although the host of ports at the back of the projector don't blend in particularly smoothly.

The latter include HDMI, VGA and Mini-USB. The usual composite and S-video connectors are included too. The speakers pack plenty of volume and will do a very adequate job where space is restricted.

ViewSonic PJD7820HD vs Epson EB-1945W

The ViewSonic lacks the advanced setup features of the Epson EB-1945W, and the vertical keystone correction didn’t match the Epson's rather more comprehensive keystone options.

However, the ViewSonic isn't without its aids. The Pattern feature, for instance, gives you some very useful test-patterns to test the image quality during installation. At this price, though, you are sacrificing the ease of setup of some other business models in favour of the PJD7820HD's video capabilities.

And does the ViewSonic make up for this handsomely. The six segment 7200rpm DLP colour wheel is highly capable, and it's backed up by a nominal 15,000:1 contrast ratio. That manufacturer’s figure may be overstated, but the PJD7820HD's colour depth is very good in HD, bringing out the darker shades in a manner that you wouldn't expect of a business model - certainly not one that can also boast strong brightness levels. Even in daylight, the picture is remarkably clear and sharp.

HDMI mode gives you only limited control over the colour settings, but good setup options on your Blu-ray player should fix this problem. The range of colour modes is nice, and these are easily cycled through using the dedicated button on the well-designed remote control.

The ViewSonic also offers 3D for those with suitable glasses and equipment, and while this isn't the most convincing or brightest 3D we've seen, it's nice as an extra.

Under normal circumstances, lamp life is said to extend to 5000 to 6000 hours, although this can be pushed up to an advertised 8000 hours by using the DynamicEco technology that automatically adjusts the brightness levels to save money.

It's not the quietest of models though, and even in eco mode, its 29dB noise output is a little loud. In normal use, the 35dB of fan noise will makes this projector’s presence known.
