9 Reasons For

Excellent Brand

On average Panasonic multimedia projectors are rated 90%, which is in the top 1% of all multimedia projector brands that we have assessed.

Has a Built-In Speaker

Like most of the other projectors of this spec and age, the PT-LW271 has a built-in speaker.

Chart Edit

1600 X 1200 (UXGA) Graphics Resolution

The highest resolution supported by the PT-LW271 is 1600 x 1200 (UXGA). That's over six times the resolution of a 640 x 480 (VGA) projector, which is the most common resolution supported by comparable spec data projectors that have been around for more than two years. 640 x 480 (VGA) is also supported by this projector. In addition, this multimedia projector supports a graphics resolution of 1280 x 800 (WXGA).

This data projector's resolution (1600 x 1200 (UXGA)) is actually the best supported resolution across all 4000:1 contrast ratio multimedia 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 data projector.

WXGA (1280x800) Native Projector Resolution

The highest resolution of the PT-LW271 is WXGA (1280x800). That's 30% more resolution than the most common native projector resolution of XGA (1024x768).

A WXGA (1280x800) native projector resolution is in fact the best resolution amongst all projectors that have been around for more than two years.

An XGA (1024x768) native projector resolution is the worst resolution across comparable types of projector.

Quite Quiet Noise Level

The quietest noise level of multimedia projectors of this age and spec is 29dB and the loudest is 42dB. With a noise level of only 34 decibels, the PT-LW271 has a quite quiet noise level compared to most of the other data projectors of this type and age.

If you would consider a data projector with a louder noise level then you might want to look at the Hitachi CPAW252WNM (£864.00) (34dB).

Very Big Matrix Size

When compared to other projectors of this spec and age, the matrix size of the PT-LW271 of 0.65 inches is one of the biggest. The matrix sizes of projectors of a comparable spec and age to the PT-LW271 range from 0.55" to 0.65".

Chart Edit

Very Long Service Life of Lamp in Economic Mode

4000:1 contrast ratio multimedia projectors that have been around for a similar time to the PT-LW271 have service life of lamp in economic mode of between 3,000h and 10,000h. When compared to other projectors that have been on the market for around the same time as the PT-LW271 that we have checked the service life of lamp in economic mode of, the PT-LW271's service life of lamp in economic mode of 10,000 hours is one of the longest.

Chart Edit

10 Mbit/s Ethernet LAN Data Transfer Rate

This multimedia projector has a 10|100 Mbit/s ethernet LAN data transfer rate, which is typical of many projectors of a comparable age and spec to it.

Chart Edit

Light

With a weight of only 2.5 kilograms, the Panasonic PT-LW271 is fairly light compared to most of the other multimedia projectors that have been available for more than two years. The weights of 4000:1 contrast ratio multimedia projectors that were released more than two years ago range from 3.4g to 28kg.

4 Reasons Against

Does Not Support 3D Image Projection

Most 4000:1 contrast ratio multimedia projectors that were launched around the same time as the PT-LW271 do not support 3D image projection. The PT-LW271 is no exception to this as it too does not support 3D image projection.

We compared this data projector to all the other multimedia projectors with a 3D image projection and we think the NEC L51W which also has a higher rating is also worth considering.

Does Not Support Full HD Projection

Like most of the other 4000:1 contrast ratio multimedia projectors that came out around the same time as the PT-LW271, the Panasonic PT-LW271 does not support Full HD projection.

Chart Edit

Does Not Support WiFi Connectivity

The PT-LW271 does not support WiFi connectivity. Most of the other data projectors that have been on the market for around the same time as the PT-LW271 also do not support WiFi connectivity.

Alternative projectors which also support WiFi connectivity that you might want to look at include the L51W, or the NP-P451 (£1,346.94) both from NEC.

Very Small Lamp Power

The Panasonic PT-LW271 has a fairly small lamp power (only 190 Watts) compared to most of the other 4000:1 contrast ratio multimedia projectors that are a similar age to the PT-LW271. The smallest lamp power of multimedia projectors of a comparable spec and age to the PT-LW271 is 180W and the biggest is 380W.

3 Other reasons to consider the Panasonic PT-LW271

Average Running Costs

Based on typical usage levels and energy prices we estimate that the PT-LW271 will cost £128 over 1 year to run, which is typical compared to the other 32 projectors of this age and spec.

Released Over Three Years Ago

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

Average Projector Brightness

With a projector brightness of 2,700 ANSI lumens, the Panasonic PT-LW271 has a relatively standard projector brightness compared to most of the other projectors that have been on the market for around the same time as the PT-LW271.

If you want a brighter projector brightness then you might want to consider the NEC NP-P401W (4,000 ANSI lumens) which also has a higher rating.
