6 Reasons For

Panasonic Has Excellent Reviews for Its Projectors

Projectors built by Panasonic generally have excellent ratings compared to other brands.

Supports 3D Image Projection

Like most of the other projectors that have been on the market for a similar time to the PT-CW331, the Panasonic PT-CW331 supports 3D image projection.

We think you might also be interested in some of the alternative projectors which support 3D image projection currently available including the Panasonic PTCW330U which has better reviews.

Has a Built-In Speaker

The Panasonic PT-CW331 has a built-in speaker. Most of the other projectors of this age and spec also have a built-in speaker.

There are a number of other multimedia projectors with a built-in speaker currently available that you might also want to consider including the Panasonic PTCW330U which has better reviews.

1920 X 1080 (HD 1080) Graphics Resolution

The PT-CW331 supports a maximum resolution of 1920 x 1080 (HD 1080). That's over two times the resolution of a 1280 x 800 data projector, which is the most common resolution supported by 8000:1 contrast ratio projectors that have been available for a similar time to the PT-CW331. In addition, this data projector support graphics resolutions of 720 x 480, 720 x 576, 832 x 624, 1280 x 720 (HD 720), 1280 x 800 (WXGA), 1366 х 768, 1400 x 1050 (SXGA+), 1440 x 900 (WXGA+), 1600 x 1200 (UXGA) and 1680 x 1050 (WSXGA+) and 640 x 480 (VGA).

A 1920 x 1080 (HD 1080) graphics resolution is in fact the best supported resolution across all similar spec projectors that were released more than two years ago.

A 640 x 480 (VGA) graphics resolution is the worst supported resolution across similar types of projector.

WXGA (1280x800) Native Projector Resolution

This multimedia projector has a native projector resolution of WXGA (1280x800), which is typical of many similar spec projectors that have been around for a comparable time to it.

Chart Edit

10 Mbit/s Ethernet LAN Data Transfer Rate

This data projector has a 10|100 Mbit/s ethernet LAN data transfer rate, which is the most commonly found ethernet LAN data transfer rate on projectors that have been around for around the same time as it.

3 Reasons Against

Does Not Support Full HD Projection

The Panasonic PT-CW331 does not support Full HD projection. Most of the other similar spec data projectors that came out more than two years ago also do not support Full HD projection.

We think you might also be interested in alternative projectors which also support Full HD projection including the Viewsonic PRO8520HD, or the Sony VPL-FHZ55 ($5,079.95) which also has a higher rating.

Does Not Support WiFi Connectivity

Most comparable spec multimedia projectors that were released more than two years ago do not support WiFi connectivity. The PT-CW331 is no exception to this as it too does not support WiFi connectivity.

Chart Edit

Quite Short Service Life of Lamp in Economic Mode

The average service life of lamp in economic mode of 8000:1 contrast ratio projectors that have been around for a comparable time to the PT-CW331 is 4,400h, and the service life of lamp in economic mode range from 3,000h to 6,000h. With a service life of lamp in economic mode of only 4,000 hours, the PT-CW331 has one of the shorter service life of lamp in economic mode amongst projectors of this age.

3 Other reasons to consider the Panasonic PT-CW331

Released Over Three Years Ago

It was over three years ago when this multimedia projector was released.

Average Noise Level

With a noise level of 37 decibels, the Panasonic PT-CW331 has a pretty standard noise level compared to most of the other 8000:1 contrast ratio projectors that were released more than two years ago.

We compared this multimedia projector to all the other 37dB noise level data projectors and we think because of it's better review score, the Panasonic PTCW330U is also worth considering.

Average Projector Brightness

With a projector brightness of 3,100 ANSI lumens, the PT-CW331 has a relatively standard projector brightness compared to most of the other multimedia projectors of this spec and age.

We compared this projector to all the other 3,100 ANSI lumens brightness data projectors and we think because of it's better review score, the Panasonic PTCW330U is also worth considering.

Data projectors with a brighter projector brightness that might also be worth considering include the IN3134a ($543.52) (4,200 ANSI lumens), or the IN3136a ($760.00) (4,500 ANSI lumens) both from Infocus which also has a higher rating.
