7 Reasons For

Excellent Brand

Data projectors built by Panasonic are some of the best data projectors according to average reviews from experts and owners.

Has a Built-In Speaker

Like most of the other data projectors that were released more than two years ago, the Panasonic PT-EW640 has a built-in speaker.

We compared this multimedia projector to all the other projectors with a built-in speaker and we think the Epson EB-4950WU[plb_1949830_price] which is cheaper is also worth considering.

We think you might also be interested in other projectors which also have a built-in speaker including the NEC PA572[plb_2406093_price], or the Panasonic PT-EX800[plb_2130355_price].

Quite Quiet Noise Level

With a noise level of only 35 decibels, the Panasonic PT-EW640 has one of the quieter noise levels amongst comparable spec projectors of this age. 5000:1 contrast ratio data projectors that have been on the market for around the same time as the PT-EW640 have noise levels of between 29dB and 48dB.

If you don't mind having a louder noise level then you might want to look at the Epson EB-4950WU[plb_1949830_price] (38dB) which is also cheaper.

Chart Edit

Quite Big Uniformity

With a uniformity of 90 percent, the PT-EW640 has a quite big uniformity compared to most of the other projectors of a similar age and spec to the PT-EW640. Across all the 5000:1 contrast ratio data projectors that were released more than two years ago the uniformities range from 80% to 95%.

Chart Edit

100V AC Input Voltage

This multimedia projector has a 100 - 240V AC input voltage, which is typical of many 5000:1 contrast ratio data projectors that were released more than two years ago.

Chart Edit

Very Quiet Noise Level in Economy Mode

The Panasonic PT-EW640 has a quite quiet noise level in economy mode (only 29 decibels) compared to most of the other 5000:1 contrast ratio data projectors that have been on the market for more than two years. The average noise level in economy mode of projectors that are a similar age to the PT-EW640 is 31dB.

7 Reasons Against

Does Not Support Full HD Projection

Most 5000:1 contrast ratio data projectors that have been on the market for around the same time as the PT-EW640 do not support Full HD projection. The PT-EW640 is no exception to this as it too does not support Full HD projection.

We compared this projector to all the other data projectors with a Full HD projection and we think the Epson EB-4950WU[plb_1949830_price] is also worth considering.

Does Not Support 3D Image Projection

The PT-EW640 does not support 3D image projection. Most of the other similar spec multimedia projectors that came out more than two years ago also do not support 3D image projection.

It is worth considering other multimedia projectors which also support 3D image projection including the Epson EB-4950WU[plb_1949830_price].

Does Not Support WiFi Connectivity

The Panasonic PT-EW640 does not support WiFi connectivity, although keep in mind that most of the other similar spec data projectors that have been available for a comparable time to the PT-EW640 also do not support WiFi connectivity.

It is worth also looking at alternative projectors which also support WiFi connectivity including the Epson EB-4950WU[plb_1949830_price].
