8 Reasons For

Excellent Brand

Multimedia projectors manufactured by Panasonic have an average rating of 91 out of 100, which is in the top 1% of all projector manufacturers that we have looked at.

Has a Built-In Speaker(s)

Like most of the other projectors that have been on the market for around the same time as the PT-LW271, the PT-LW271 has a built-in speaker(s).

Chart Edit

1600 X 1200 (UXGA) Supported Graphics Resolutions

The Panasonic PT-LW271 supports a maximum resolution of 1600 x 1200 (UXGA). That's over six times the resolution of a 640 x 480 (VGA) projector, which is the most frequently found resolution supported by multimedia projectors of this age and type. 640 x 480 (VGA) is also supported by this multimedia projector. In addition, this data projector supports a supported graphics resolutions of 1280 x 800 (WXGA).

A 1600 x 1200 (UXGA) supported graphics resolutions is in fact the best supported resolution amongst all projectors of a comparable spec and age to the PT-LW271.

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

WXGA (1280x800) Projector Native Resolution

The highest resolution of the PT-LW271 is WXGA (1280x800). That's 30% more resolution than a XGA (1024x768) projector, which is the most frequently found resolution.

This multimedia projector's resolution (WXGA (1280x800)) is in fact the best resolution amongst all projectors of a comparable age and spec to the PT-LW271.

Amongst comparable types of multimedia projector the worst resolution is XGA (1024x768).

Very Big Matrix Size

At 0.65 inches, the PT-LW271 has a very big matrix size compared to most of the other projectors of this age and spec. Across all the similar spec data projectors that were released more than two years ago the matrix sizes range from 0.55" to 0.65".

Chart Edit

Three VGA (D-Sub) Ports Quantitys

The PT-LW271 has more VGA (D-Sub) ports quantitys than most of the projectors of a similar age and type to the PT-LW271. Most of the data projectors of a comparable spec and age to the PT-LW271 only have between one and two VGA (D-Sub) ports quantitys, however this multimedia projector has three VGA (D-Sub) ports quantitys.

Chart Edit

10 Mbit/s Ethernet LAN Data Rates

This projector has a 10|100 Mbit/s ethernet LAN data rates, which is the most commonly found ethernet LAN data rates on projectors of a comparable age and spec to it.

Chart Edit

Light

With a weight of only 2.5 kilograms, the PT-LW271 is one of the lighter data projectors of this age and spec amongst 4000:1 contrast ratio projectors of this age. The average weight of multimedia projectors of a comparable age and spec to the PT-LW271 is 4kg.

Chart Edit

7 Reasons Against

Does Not Support 3D

Most data projectors of a similar spec and age to the PT-LW271 do not support 3D. The Panasonic PT-LW271 is no exception to this as it too does not support 3D.

We compared this data projector to all the other multimedia projectors with a 3D and we think the NEC L51W (£377.69) which also has a higher rating is also worth considering.

Does Not Support Full HD

The PT-LW271 does not support full HD, although it is worth keeping in mind that most of the other projectors that were launched more than two years ago also do not support full HD.

Chart Edit

Does Not Support Wi-Fi

The PT-LW271 does not support wi-Fi. Most of the other 4000:1 contrast ratio projectors that came out around the same time as the PT-LW271 also do not support wi-Fi.

Chart Edit

Quite Dim Projector Brightness

At only 2,700 ANSI lumens, the Panasonic PT-LW271 has a quite dim projector brightness compared to most of the other 4000:1 contrast ratio projectors that came out more than two years ago. The average projector brightness of multimedia projectors that have been on the market for a similar time to the PT-LW271 is 3,700 ANSI lumens, and the projector brightnesss range from 500 ANSI lumens to 13,000 ANSI lumens.

If you want a brighter projector brightness then you might also want to consider the NEC P401 (3,300 ANSI lumens) which also has a higher rating.

Very Small Bulb Power

The bulb powers of 4000:1 contrast ratio projectors that have been on the market for a comparable time to the PT-LW271 range from 180W to 380W. At only 190 Watts, the PT-LW271 has a fairly small bulb power compared to most of the other 4000:1 contrast ratio projectors that have been available for around the same time as the PT-LW271.

Chart Edit

Quite Low RMS Rated Power

With an RMS rated power of only 8 Watts, the PT-LW271 has a fairly low RMS rated power compared to most of the other 4000:1 contrast ratio projectors that are a similar age to the PT-LW271. Similar spec data projectors that were released more than two years ago have RMS rated powers of between 2W and 20W.

Chart Edit

Only One HDMI Ports Quantity

Most 4000:1 contrast ratio projectors that have been around for a similar time to the PT-LW271 have one HDMI ports quantity, including the Panasonic PT-LW271 which has one HDMI ports quantity.

Average Noise Level

At 34 decibels, the Panasonic PT-LW271 has a relatively typical noise level compared to most of the other 4000:1 contrast ratio projectors that came out more than two years ago.

Other data projectors with a louder noise level that you might want to look at include the CP-AW252 (£864.00) (34dB), or the CPAW252WNM (34dB) both from Hitachi.
