9 Reasons For

Panasonic Multimedia Projectors Have Excellent Reviews

We checked the reviews from experts and users of hundreds of multimedia projectors to determine an average rating for each multimedia projector manufacturer. On average multimedia projectors from Panasonic have excellent ratings from experts and users.

Quite Bright Projector Brightness

With a projector brightness of 6,000 ANSI lumens, the PT-DW640 has a fairly bright projector brightness compared to most of the other similar spec multimedia projectors that have been on the market for a comparable time to the PT-DW640. The average projector brightness of 2000:1 contrast ratio data projectors that are a comparable age to the PT-DW640 is 4,100 ANSI lumens, and the projector brightness range from 110 ANSI lumens to 10,000 ANSI lumens.

Chart Edit

1920 X 1200 (WUXGA) Graphics Resolution

The highest resolution supported by the PT-DW640 is 1920 x 1200 (WUXGA). That's over seven times the resolution of the most frequently found graphics resolution of 640 x 480 (VGA) (which is also supported by this Panasonic projector). In addition, this multimedia projector supports a graphics resolution of 1280 x 800 (WXGA).

A 1920 x 1200 (WUXGA) graphics resolution is in fact the best supported resolution amongst all 2000:1 contrast ratio data projectors that have been available for around the same time as the PT-DW640.

The worst supported resolution amongst similar types of projector is 640 x 480 (VGA).

Quite Quiet Noise Level

The PT-DW640 has a fairly quiet noise level (only 35 decibels) compared to most of the other 2000:1 contrast ratio data projectors that have been around for around the same time as the PT-DW640. The quietest noise level of 2000:1 contrast ratio data projectors that were released more than two years ago is 28dB and the loudest is 42dB.

Chart Edit

WXGA (1280x800) Native Projector Resolution

The highest resolution of the PT-DW640 is WXGA (1280x800). That's 30% more resolution than a XGA (1024x768) data projector, which is the most frequently found resolution. Projectors of this age and type native projector resolutions range from XGA (1024x768) (worst) to WUXGA (1920x1200) (best).

Chart Edit

Two Lamps

Most data projectors of this spec and age have between one and two lamps, including the PT-DW640 which has two lamps.

Chart Edit

Two RS-232 Ports

The PT-DW640 is a two RS-232 port projector. Most of the other projectors that came out more than two years ago only have one RS-232 port.

Chart Edit

Fairly Big Uniformity

The average uniformity of comparable spec data projectors that are a similar age to the PT-DW640 is 86%, and the uniformities range from 78% to 95%. The PT-DW640 has one of the bigger uniformities (90 percent) amongst multimedia projectors of this age.

Chart Edit

Quite Quiet Noise Level in Economy Mode

The average noise level in economy mode of similar spec projectors that were launched around the same time as the PT-DW640 is 30dB. With a noise level in economy mode of only 29 decibels, the Panasonic PT-DW640 has a fairly quiet noise level in economy mode compared to most of the other 2000:1 contrast ratio data projectors that are a comparable age to the PT-DW640.

Chart Edit

9 Reasons Against

Does Not Have a Built-In Speaker

The Panasonic PT-DW640 does not have a built-in speaker. Most of the other similar spec projectors that were launched more than two years ago do have a built-in speaker.

Chart Edit

Does Not Support Full HD Projection

Most comparable spec multimedia projectors that came out around the same time as the PT-DW640 do not support Full HD projection. The PT-DW640 is no exception to this as it too does not support Full HD projection.

There are a number of alternative projectors which also support Full HD projection that you might want to consider including the AAXA Technologies LED Android Pico Projector[plb_3156294_price] which also has a higher rating.

Read more Less Chart Edit

Does Not Support 3D Image Projection

The PT-DW640 does not support 3D image projection. Most of the other projectors of a comparable age and spec to the PT-DW640 also do not support 3D image projection.

We think you might also be interested in other data projectors which also support 3D image projection including the NEC U310W[plb_1531485_price] which also has a higher rating.

Read more Less Chart Edit

Does Not Support WiFi Connectivity

The PT-DW640 does not support WiFi connectivity, although it is worth noting that most of the other 2000:1 contrast ratio data projectors that are a similar age to the PT-DW640 also do not support WiFi connectivity.

We think you might also be interested in other multimedia projectors which also support WiFi connectivity including the Epson PowerLite 1761W[plb_1735741_price], or the AAXA Technologies M2 Micro[plb_1759924_price] which is also higher rated.

Read more Less Chart Edit

High Running Costs

Based on average energy prices and usage levels we estimate that the PT-DW640 will cost £281 over 1 year to run, which makes it one of the less economic to run 2000:1 contrast ratio data projectors that came out more than two years ago.

Chart

Very Low Maximum Horizontal Synchronization

At only 91 kilohertz, the Panasonic PT-DW640 has a quite low maximum horizontal synchronization compared to most of the other similar spec data projectors that have been around for more than two years. The maximum horizontal synchronization of 2000:1 contrast ratio data projectors that have been available for a similar time to the PT-DW640 range from 91kHz to 110kHz.

Chart Edit

Very Low Maximum Vertical Synchronization

At only 0.085 kilohertz, the Panasonic PT-DW640 has a fairly low maximum vertical synchronization compared to most of the other data projectors of a similar age and spec to the PT-DW640. The maximum vertical synchronization of 2000:1 contrast ratio data projectors that were released around the same time as the PT-DW640 range from 0.085kHz to 120kHz.

Chart Edit

Only One VGA (D-Sub) Port

The PT-DW640 is a one VGA (D-Sub) port multimedia projector.

Chart Edit

Very Heavy

With a weight of 16 kilograms, the PT-DW640 is quite heavy compared to most of the other projectors of a comparable spec and age to the PT-DW640. The weights of 2000:1 contrast ratio data projectors that have been around for a similar time to the PT-DW640 range from 370g to 23kg, and the average weight is 6.5kg.
