13 Reasons For

Panasonic Data Projectors Have Excellent Reviews

Projectors produced by Panasonic have an average rating of 91%, which is in the top 1% of all projector brands that we have looked at.

Supports Full HD

The PT-DZ21 supports full HD, which is unusual. Most of the other data projectors of a similar age and type to the PT-DZ21 do not support full HD.

There are a number of alternative projectors which support full HD currently available that you might also want to consider including the Epson 1975W[plb_3009713_price] which has better reviews.

Supports 3D

The Panasonic PT-DZ21 supports 3D, unlike most of the other projectors that have been on the market for around the same time as the PT-DZ21 which do not support 3D.

We compared this projector to all the other projectors which support 3D and we think the Optoma ML550[plb_1947306_price] which has better reviews is also worth considering.

WUXGA (1920x1200) Projector Native 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).

A WUXGA (1920x1200) projector native resolution is in fact the best resolution across all 10000:1 contrast ratio projectors that were launched around the same time as the PT-DZ21.

The worst resolution amongst comparable types of projector is SVGA (800x600).

1920 X 1200 (WUXGA) Supported Graphics Resolutions

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

A 1920 x 1200 (WUXGA) supported graphics resolutions is actually the best supported resolution across all comparable spec projectors that are a similar age to the PT-DZ21.

Across comparable types of projector the worst supported resolution is 640 x 480 (VGA).

Very Big Matrix Size

The matrix sizes of data projectors that are a comparable age to the PT-DZ21 range from 0.45" to 0.96". When compared to other multimedia projectors that were launched around the same time as the PT-DZ21 that we have assessed, the Panasonic PT-DZ21's matrix size of 0.96 inches is one of the biggest.

Chart Edit

Four Lamps Quantitys

The PT-DZ21 is a four lamps quantity projector. Most of the other multimedia projectors of a comparable spec and age to the PT-DZ21 only have between one and three lamps quantitys.

Chart Edit

Fairly Big Bulb Power

The PT-DZ21 has a very big bulb power (465 Watts) compared to most of the other projectors that are a similar age to the PT-DZ21. The smallest bulb power of projectors of this age and spec is 15W, the biggest is 840W, and the average bulb power is 240W.

Chart Edit

Two RS-232 Portss

Most similar spec projectors that were released more than two years ago have between one and two RS-232 portss, including the PT-DZ21 which has two RS-232 portss.

Chart Edit

Ten BNC Input Portss

Most of the other projectors that are a similar age to the PT-DZ21 only have between one and nine BNC input portss, however the PT-DZ21 has ten BNC input portss.

Chart Edit

Five Component Video (YPbPr/YCbCr) Ins

The PT-DZ21 is a five component video (YPbPr/YCbCr) in multimedia projector. Most of the other multimedia projectors of a similar age and type to the PT-DZ21 only have between one and four component video (YPbPr/YCbCr) ins.

Chart Edit

Four VGA (D-Sub) Ports Quantitys

Most of the other similar spec projectors that have been available for a comparable time to the PT-DZ21 only have between one and three VGA (D-Sub) ports quantitys, however the PT-DZ21 has four VGA (D-Sub) ports quantitys.

Chart Edit

10 Mbit/s Ethernet LAN Data Rates

This data projector has a 10|100 Mbit/s ethernet LAN data rates, which is typical of many multimedia projectors of a comparable spec and age to it.

Chart Edit

9 Reasons Against

Only 100V AC Input Voltage

This multimedia projector has a 100 - 240V AC input voltage, which is the most commonly found AC input voltage on data projectors that were launched around the same time as it.

Chart Edit

Does Not Have a Built-In Speaker(s)

The PT-DZ21 does not have a built-in speaker(s), unlike most of the other 10000:1 contrast ratio projectors that have been around for around the same time as the PT-DZ21.

Alternative multimedia projectors which also have a built-in speaker(s) that you might want to look at include the NEC NP-M282[plb_2338575_price] which is also higher rated.

Read more Less Chart Edit

Does Not Support Wi-Fi

The Panasonic PT-DZ21 does not support wi-Fi. Most of the other data projectors of this age and type also do not support wi-Fi.

We compared all the other multimedia projectors which also support wi-Fi to this projector and we think the Benq W1500[plb_1561671_price], or the Epson PowerLite 1222[plb_2225031_price] which is also higher rated is also worth considering.

Quite Dim Projector Brightness

With a projector brightness of only 2,000 ANSI lumens, the PT-DZ21 has a fairly dim projector brightness compared to most of the other 10000:1 contrast ratio projectors that are a similar age to the PT-DZ21. 10000:1 contrast ratio projectors that came out around the same time as the PT-DZ21 have projector brightnesss of between 300 ANSI lumens and 12,000 ANSI lumens, and the average projector brightness is 3,300 ANSI lumens.

We compared all the other 2,000 ANSI lumens brightness data projectors to this projector and we think because of it's better review score, the W1300[pl_1998671_price], the W1080[pl_1495063_price], and the W1070[pl_1522360_price] all from Benq is also worth considering.

If this Panasonic data projector projector brightness is too dim for you then you might also want to consider the Benq W1350[plb_2750779_price] (2,500 ANSI lumens) which also has a higher rating.

Very Slow Dot Clock Scanning Frequency

At only 20 megahertz, the PT-DZ21 has a quite slow dot clock scanning frequency compared to most of the other comparable spec data projectors that have been around for a similar time to the PT-DZ21. The slowest dot clock scanning frequency of 10000:1 contrast ratio projectors that have been around for a comparable time to the PT-DZ21 is 20MHz and the fastest is 170MHz.

Chart Edit

Quite Short Service Life of Lamp

10000:1 contrast ratio projectors that have been around for around the same time as the PT-DZ21 have service life of lamps of between 500h and 30,000h, and the average service life of lamp is 6,000h. At only 2,000 hours, the PT-DZ21 has a very short service life of lamp compared to most of the other data projectors of this type and age.

Chart Edit

Running Costs Are High

Based on average usage levels and energy prices we estimate that the 1 year running cost of the PT-DZ21 is £804, which makes it one of the less economic to run projectors of this age and spec.

Chart

Very Loud Noise Level

With a noise level of 49 decibels, the PT-DZ21's noise level is one of the loudest amongst projectors of a comparable spec and age to the PT-DZ21. The average noise level of comparable spec multimedia projectors that were released more than two years ago is 35dB, and the noise levels range from 27dB to 49dB.

Alternative multimedia projectors with a louder noise level that you might want to look at include the Benq GP10[plb_1451163_price] (36dB) which also has a higher rating.

Very Heavy

The weights of projectors that have been around for around the same time as the PT-DZ21 range from 360g to 54kg. With a weight of 54 kilograms, the Panasonic PT-DZ21's weight is one of the heaviest amongst 10000:1 contrast ratio projectors that were released around the same time as the PT-DZ21.
