Panasonic Projectors Have Excellent Reviews

Data projectors produced by Panasonic generally have excellent reviews.

Across all the 2000:1 contrast ratio data projectors that have been around for more than two years the projector brightnesss range from 110 ANSI lumens to 10,000 ANSI lumens, and the average projector brightness is 4,100 ANSI lumens. At 6,000 ANSI lumens, the PT-DW640 has a fairly bright projector brightness compared to most of the other projectors of this spec and age.

Quite Quiet Noise Level

Across all the 2000:1 contrast ratio data projectors that have been around for a comparable time to the PT-DW640 the noise levels range from 28dB to 42dB, and the average noise level is 36dB. With a noise level of only 35 decibels, the PT-DW640 has a quite quiet noise level compared to most of the other multimedia projectors that are a comparable age to the PT-DW640.

Chart Edit

WXGA (1280x800) Projector Native Resolution

The highest resolution of the PT-DW640 is WXGA (1280x800). That's 30% more resolution than the most frequently found projector native resolution of XGA (1024x768). Across all multimedia projectors of this age and spec the best resolution is WUXGA (1920x1200) and the worst is XGA (1024x768).

7 Reasons Against

Does Not Have a Built-In Speaker(s)

The PT-DW640 does not have a built-in speaker(s). Most of the other 2000:1 contrast ratio data projectors that have been available for a similar time to the PT-DW640 do have a built-in speaker(s).

Chart Edit

Does Not Support Full HD

The Panasonic PT-DW640 does not support full HD. Most of the other similar spec multimedia projectors that came out around the same time as the PT-DW640 also do not support full HD.

It is worth also looking at alternative multimedia projectors which also support full HD including the AAXA Technologies LED Android Pico Projector[plb_3156294_price].

Does Not Support 3D

Most 2000:1 contrast ratio data projectors that have been available for more than two years do not support 3D. The Panasonic PT-DW640 is no exception to this as it too does not support 3D.

We compared all the other projectors which also support 3D to this projector and we think the NEC U310W[plb_1531485_price] is also worth considering.

Does Not Support Wi-Fi

Most multimedia projectors that were launched around the same time as the PT-DW640 do not support wi-Fi. The PT-DW640 is no exception to this as it too does not support wi-Fi.

Other data projectors which also support wi-Fi that you might want to consider include the Epson PowerLite 1761W[plb_1735741_price], or the AAXA Technologies M2 Micro[plb_1759924_price] which also has a higher rating.

High Running Costs

The PT-DW640 has an average 1 year running cost of £281 based on typical usage levels and energy prices, which is in the most expensive 8% of all 85 2000:1 contrast ratio data projectors that were launched more than two years ago.

Chart

Only One VGA (D-Sub) Ports Quantity

Most multimedia projectors that have been available for around the same time as the PT-DW640 have between one and three VGA (D-Sub) ports quantitys, including the Panasonic PT-DW640 which has one VGA (D-Sub) ports quantity.

Chart Edit

Very Heavy

Across all the similar spec data projectors that came out around the same time as the PT-DW640 the weights range from 370g to 23kg. The PT-DW640 is quite heavy (16 kilograms) compared to most of the other projectors of a similar age and type to the PT-DW640.
