13 Reasons For

Panasonic Has Excellent Multimedia Projector Reviews

Panasonic is one of the best data projector brands according to average expert and user review score data that we have collected for all multimedia projectors.

Supports Full HD

The Panasonic PT-DZ21 supports full HD, which is unusual. Most of the other 10000:1 contrast ratio data projectors that have been on the market for a comparable time to the PT-DZ21 do not support full HD.

Chart Edit

Supports 3D

Unlike most of the other projectors of a comparable age and spec to the PT-DZ21 which do not support 3D, the PT-DZ21 supports 3D.

Chart Edit

WUXGA (1920x1200) Projector Native Resolution

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

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

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

1920 X 1200 (WUXGA) Supported Graphics Resolutions

The highest resolution supported by the PT-DZ21 is 1920 x 1200 (WUXGA). That's over seven times the resolution of a 640 x 480 (VGA) projector, which is the most common resolution supported by comparable spec projectors that were launched more than two years ago. 640 x 480 (VGA) is also supported by this multimedia projector.

This projector's resolution (1920 x 1200 (WUXGA)) is in fact the best supported resolution across all multimedia projectors that have been available for around the same time as the PT-DZ21.

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

Very Big Matrix Size

The PT-DZ21 has one of the biggest matrix sizes (0.96 inches) amongst 10000:1 contrast ratio data projectors of this age. The average matrix size of similar spec multimedia projectors that have been on the market for around the same time as the PT-DZ21 is 0.62".

Chart Edit

Four Lamps Quantitys

The PT-DZ21 has more lamps quantitys than most of the multimedia projectors of a comparable age and spec to the PT-DZ21. Most of the multimedia projectors of this age and type only have between one and three lamps quantitys, however this data projector has four lamps quantitys.

Chart Edit

Quite Big Bulb Power

At 465 Watts, the Panasonic PT-DZ21 has a very big bulb power compared to most of the other projectors of a similar spec and age to the PT-DZ21. The average bulb power of projectors of a comparable age and type to the PT-DZ21 is 240W, and the bulb powers range from 15W to 840W.

Chart Edit

Two RS-232 Portss

The PT-DZ21 is a two RS-232 ports multimedia projector. Most of the other multimedia projectors that were launched more than two years ago have between one and two RS-232 portss.

Chart Edit

Ten BNC Input Portss

The Panasonic PT-DZ21 is a ten BNC input ports data projector.

Chart Edit

Five Component Video (YPbPr/YCbCr) Ins

The PT-DZ21 has more component video (YPbPr/YCbCr) ins than most of the 10000:1 contrast ratio data projectors that were launched around the same time as the PT-DZ21. Most of the similar spec data projectors that were released more than two years ago only have between one and four component video (YPbPr/YCbCr) ins, however this Panasonic projector has five component video (YPbPr/YCbCr) ins.

Chart Edit

Four VGA (D-Sub) Ports Quantitys

The PT-DZ21 is a four VGA (D-Sub) ports quantity projector.

Chart Edit

10 Mbit/s Ethernet LAN Data Rates

This multimedia projector has a 10|100 Mbit/s ethernet LAN data rates, which is typical of many 10000:1 contrast ratio data projectors that are a comparable age to it.

Chart Edit

8 Reasons Against

Only 100V AC Input Voltage

This projector has a 100 - 240V AC input voltage, which is typical of many projectors that have been available for 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 data projectors that have been on the market for a comparable time to the PT-DZ21.

Chart Edit

Does Not Support Wi-Fi

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

We think you might also be interested in alternative projectors which also support wi-Fi including the Benq W1500 ($1,976.29), or the Epson PowerLite 1222 ($695.00) which also has a higher rating.

Quite Dim Projector Brightness

Across all the data projectors that were launched more than two years ago the projector brightnesss range from 300 ANSI lumens to 12,000 ANSI lumens. At only 2,000 ANSI lumens, the PT-DZ21 has a fairly dim projector brightness compared to most of the other 10000:1 contrast ratio data projectors that have been on the market for a comparable time to the PT-DZ21.

It may also be worth considering one of the alternative 2,000 ANSI lumens brightness projectors currently available including the W1300, the W1080 ($949.00), or the W1070 ($599.00) all from Benq which has better reviews.

If this multimedia projector projector brightness is not bright enough for you then you might also want to look at the Benq W1070+W (2,200 ANSI lumens), the Infocus IN8606HD (2,500 ANSI lumens), or the Epson EB-X03 (2,700 ANSI lumens).

Very Slow Dot Clock Scanning Frequency

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

Chart Edit

Quite Short Service Life of Lamp

10000:1 contrast ratio data projectors that are a comparable age to the PT-DZ21 have service life of lamps of between 500h and 30,000h, and the average service life of lamp is 6,200h. At only 2,000 hours, the Panasonic PT-DZ21 has a very short service life of lamp compared to most of the other 10000:1 contrast ratio data projectors that have been available for a comparable time to the PT-DZ21.

Chart Edit

Very Loud Noise Level

The noise level of the PT-DZ21 of 49 decibels is one of the loudest amongst data projectors that have been available for more than two years. 10000:1 contrast ratio data projectors that were released more than two years ago have noise levels of between 28dB and 49dB, and the average noise level is 35dB.

If you would consider a projector with a louder noise level then you might want to look at the Benq GP10 (36dB) which also has a higher rating.
