Other

Released Over Four Years Ago

It was December 2012 when this projector was released.


Projector

Fairly Bright Projector Brightness

2000:1 contrast ratio multimedia projectors that have been available for more than two years have projector brightnesses of between 110 ANSI lumens and 12,000 ANSI lumens. The PT-DW640 has a quite bright projector brightness (6,000 ANSI lumens) compared to most of the other 2000:1 contrast ratio multimedia projectors that have been around for around the same time as this projector.

If you want a brighter projector brightness then you might want to consider the Panasonic PT-EX610 (£1,966.54) (6,200 ANSI lumens).

WXGA (1280x800) Resolution

The PT-DW640 has a maximum resolution of WXGA (1280x800). That's 30% more resolution than the most frequently found projector native resolution of XGA (1024x768). The resolution of all 2000:1 contrast ratio multimedia projectors that were released more than two years ago ranges from XGA (1024x768) to WUXGA (1920x1200).

Video

Does Not Support Full HD

The PT-DW640 does not support full HD, although it is worth keeping in mind that most of the other data projectors of this spec and age also do not support full HD.

We compared all the other multimedia projectors which also support full HD to this multimedia projector and we think the AAXA Technologies LED Android Pico Projector which also has a higher rating is also worth considering.

What is full HD? Less Chart Hide Chart Edit

HD-Ready

The PT-DW640 is HD-Ready, as are most of the other data projectors of a similar age and type to this projector.

Performance

Quite Quiet Noise Level

The PT-DW640 has a quite quiet noise level (only 35 decibels) compared to most of the other 2000:1 contrast ratio multimedia projectors that came out more than two years ago. 2000:1 contrast ratio multimedia projectors that were released more than two years ago have noise levels of between 28dB and 73dB.

Energy

Running Costs Are High

The PT-DW640 is in the most expensive 10% of all 91 multimedia projectors of a similar age and spec that we have assessed for running costs. Based on average energy prices and usage levels, we estimate the PT-DW640 will cost £281 over 1 year to run.


Ports & Interfaces

Has a DVI Port

The Panasonic PT-DW640 has a DVI port, which is unusual. Most of the other data projectors that have been on the market for around the same time as this multimedia projector do not have a DVI port.

Networking

Has an Ethernet LAN

The PT-DW640 has an Ethernet LAN. Most of the other projectors that were released more than two years ago also have an Ethernet LAN.
