12 Reasons For

Excellent Brand

We checked the reviews from users and experts of hundreds of projectors to determine an average rating for each data projector brand. On average data projectors manufactured by Panasonic have excellent ratings from experts and owners.

Very Bright Projector Brightness

With a projector brightness of 20,000 ANSI lumens, the PT-DZ21's projector brightness is one of the brightest amongst 10000:1 contrast ratio multimedia projectors that are a similar age to the PT-DZ21. The projector brightness of 10000:1 contrast ratio multimedia projectors that were released more than two years ago range from 300 ANSI lumens to 20,000 ANSI lumens, and the average projector brightness is 3,400 ANSI lumens.

Chart Edit

Supports Full HD Projection

The Panasonic PT-DZ21 supports Full HD projection. Most of the other 10000:1 contrast ratio multimedia projectors that were launched around the same time as the PT-DZ21 do not support Full HD projection.

We compared this data projector to all the other projectors which support Full HD projection and we think because of it's better review score, the NEC NP-M322 ($679.00) is also worth considering.

Supports 3D Image Projection

Unlike most of the other 10000:1 contrast ratio multimedia projectors that have been around for around the same time as the PT-DZ21 which do not support 3D image projection, the PT-DZ21 supports 3D image projection.

There are a number of alternative multimedia projectors which support 3D image projection currently available that you might also want to consider including because of it's better review score, the Epson EX6220.

WUXGA (1920x1200) Native Projector Resolution

The PT-DZ21 has a maximum resolution of WUXGA (1920x1200). That's over two times the resolution of a WXGA (1280x800) projector, which is the most frequently found resolution.

This projector's resolution (WUXGA (1920x1200)) is actually the best resolution across all projectors that have been on the market for around the same time as the PT-DZ21.

Across comparable types of projector the worst resolution is SVGA (800x600).

1920 X 1200 (WUXGA) Graphics Resolution

The highest resolution supported by the PT-DZ21 is 1920 x 1200 (WUXGA). That's over seven times the resolution of the most frequently found graphics resolution of 640 x 480 (VGA) (which is also supported by this multimedia projector).

A 1920 x 1200 (WUXGA) graphics resolution is in fact the best supported resolution amongst all projectors of this age and spec.

The worst supported resolution amongst similar types of projector is 640 x 480 (VGA).
