ViewSonic PJD7820HD review - HD projector good for business


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.

business who need to be able to project large, sharp and extremely accurate video and HD images in a variety of conditions, the PJD7820HD has great specifications and strong performance that belies its £720 price tag.

ViewSonic PJD7820HD Projector Review


Steve Withers takes a look at a budget projector from ViewSonic. Is the price too good to be true?

Good 3D ; Price

Poor blacks ; Scaling on all content ; Inaccurate Colours ; Limited controls

Whilst it might be tempting to buy a very cheap projector, there are always going to be trade-offs in order to reach a certain price point. Generally the quality of the lens is compromised to reduce costs, as is build quality and features. The...

ViewSonic PJD7820HD


The ViewSonic PJD7820HD is a lightweight 1080p data projector that does well in showing sharp text.

1080p resolution. Sharp text. Can project 3D content from Blu-ray players. Lightweight. Three-year warranty.

Subpar video with significant rainbow effect. Image quality suffers over a VGA connection. Weak audio.

If you don't show images with the small text or intricate detail that requires 1080p resolution, you might be better off with a WXGA data projector such as the Editors' Choice Epson PowerLite 955W WXGA 3LCD Projector. This 3,000-lumen projector showed...

Viewsonic PJD7820HD


The PJD7820HD is a $699 projector suitable for business, and home use.

Excellent brightness - measured a maximum of over 3500 lumens ; More than enough brightness at max to handle very large rooms, and handle even 10 foot screens with pretty good color for commercial applications ; Two computer inputs, and a monitor out...

Tabletop setup would be easier if both rear feet were adjustable ; Remote control is not backlit ; Black levels are pretty entry level as a home projector ; On the home side: Lacks CFI for smooth motion (rare on entry level projectors) ; Very...

Impressive. Almost sensational. The Viewsonic PJD7820HD is all about price performance. We consider it to be a typically equipped low cost portable business projector, of the DLP variety, except that we're used to merely WXGA resolution, half the...
