Released Over Three Years Ago

Panasonic released the PT-DZ21 in August 2013.


Projector

Quite Dim Projector Brightness

The projector brightnesses of 10000:1 contrast ratio projectors that are a similar age to this data projector range from 300 ANSI lumens to 20,000 ANSI lumens, and the average projector brightness is 3,400 ANSI lumens. The Panasonic PT-DZ21 has one of the dimmer projector brightnesses (only 2,000 ANSI lumens) amongst comparable spec multimedia projectors of this age.

If this projector projector brightness is too dim for you then you might want to look at the Benq W1070+W (2,200 ANSI lumens), or the Infocus IN8606HD (£549.99) (2,500 ANSI lumens).

WUXGA (1920x1200) Resolution

The PT-DZ21 has a maximum resolution of WUXGA (1920x1200). That's over two times the resolution of the most common projector native resolution of WXGA (1280x800).

This projector's resolution (WUXGA (1920x1200)) is actually the best resolution across all data projectors of this age and type.

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

Video

Supports Full HD

The PT-DZ21 supports full HD, which is unusual. Most of the other data projectors of this spec and age do not support full HD.

It may also be worth considering one of the other data projectors which support full HD currently available including the NEC NP-M322X, or the Epson Home Cinema 600 which both of have better reviews.

HD-Ready

The PT-DZ21 is HD-Ready. Most of the other projectors that were released more than two years ago also are HD-Ready.

The bulb powers of comparable spec multimedia projectors that have been on the market for a similar time to this projector range from 15W to 840W.

Quite Short Service Life of Lamp

The PT-DZ21 has one of the shortest service life of lamps (only 2,000 hours) amongst multimedia projectors of this age.

Energy

Running Costs Are High

The PT-DZ21 is one of the less economic to run data projectors of a similar spec and age that we have assessed for running costs. Based on average energy prices, we estimate the PT-DZ21 will cost £804 over 1 year to run.


Performance

Very Loud Noise Level

Across all the multimedia projectors that came out more than two years ago the noise levels range from 28dB to 49dB, and the average noise level is 36dB. With a noise level of 49 decibels, the PT-DZ21 has one of the loudest noise levels amongst 10000:1 contrast ratio projectors of this age.

Multimedia projectors with a louder noise level that might be worth considering include the PT-DZ870 (£11,840.40) (40dB), or the PT-DW11 (£16,251.60) (45dB) both from Panasonic.
