7 Reasons For

Panasonic Multimedia Projectors Have Excellent Reviews

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

Has a Built-In Speaker(s)

The PT-EW640E has a built-in speaker(s), as do most of the other 5000:1 contrast ratio multimedia projectors that have been available for a similar time to the PT-EW640E.

Other projectors with a built-in speaker(s) currently available that you might want to look at include cheaper projectors such as the Epson EB-4950WU[plb_1949830_price].

We compared all the other projectors which also have a built-in speaker(s) to this multimedia projector and we think the NEC PA572[plb_2406093_price], or the Panasonic PT-EW730[plb_2130354_price] is also worth considering.

Quite Quiet Noise Level

The noise levels of 5000:1 contrast ratio multimedia projectors that have been available for a similar time to the PT-EW640E range from 29dB to 48dB, and the average noise level is 37dB. At only 35 decibels, the PT-EW640E has a quite quiet noise level compared to most of the other 5000:1 contrast ratio multimedia projectors that were released more than two years ago.

Other projectors with a louder noise level that you might want to look at include the Epson EB-4950WU[plb_1949830_price] (38dB and cheaper).

Chart Edit

Three VGA (D-Sub) Ports Quantitys

The Panasonic PT-EW640E has more VGA (D-Sub) ports quantitys than most of the multimedia projectors of this type and age.

6 Reasons Against

Does Not Support Full HD

The PT-EW640E does not support full HD, although it is worth keeping in mind that most of the other comparable spec multimedia projectors that have been around for around the same time as the PT-EW640E also do not support full HD.

We compared all the other projectors which also support full HD to this projector and we think the Epson EB-4950WU[plb_1949830_price] which is also cheaper is also worth considering.

We compared this multimedia projector to all the other multimedia projectors with a 3D and we think the Epson EB-4950WU[plb_1949830_price] is also worth considering.
