8 Reasons For

Epson Has Good Reviews for Its Multimedia Projectors

Epson has good average ratings for its 3000:1 contrast ratio projectors as well as across its entire projector range compared to other brands.

Supports WiFi Connectivity

The EB-421i supports WiFi connectivity, unlike most of the other multimedia projectors that have been around for around the same time as the EB-421i which do not support WiFi connectivity.

Chart Edit

Has a Built-In Speaker

Like most of the other projectors of a comparable type and age to the EB-421i, the EB-421i has a built-in speaker.

It is worth also looking at other multimedia projectors which also have a built-in speaker including the Sony VPL-SX226.

Three Headphone Outputs

The EB-421i has more headphone outputs than most of the projectors that were launched around the same time as the EB-421i. This Epson projector is a three headphone output multimedia projector compared to most of the multimedia projectors that are a comparable age to the EB-421i which only have between one and two headphone outputs.

Chart Edit

Very Light

Across all the projectors of this type and age the weights range from 3.4kg to 6.7kg, and the average weight is 5kg. With a weight of only 3.9 kilograms, the EB-421i is one of the lighter 3000:1 contrast ratio projectors that have been around for around the same time as the EB-421i amongst similar spec data projectors of this age.

Chart Edit

Very Narrow

Across all the multimedia projectors of a similar type and age to the EB-421i the widths range from 320mm to 450mm, and the average width is 380mm. At only 345 millimeters, the Epson EB-421i is quite narrow compared to most of the other 3000:1 contrast ratio projectors that are a comparable age to the EB-421i.

Chart Edit

10 Mbit/s Ethernet LAN Data Transfer Rate

This projector has a 10|100 Mbit/s ethernet LAN data transfer rate, which is the most commonly found ethernet LAN data transfer rate on 3000:1 contrast ratio projectors that are a comparable age to it.

Chart Edit

Quite Quiet Noise Level in Economy Mode

Across all the comparable spec multimedia projectors that were launched around the same time as the EB-421i the noise levels in economy mode range from 24dB to 40dB, and the average noise level in economy mode is 32dB. With a noise level in economy mode of only 28 decibels, the EB-421i has a fairly quiet noise level in economy mode compared to most of the other comparable spec data projectors that were released one year ago.

Chart Edit

6 Reasons Against

Does Not Support 3D Image Projection

The EB-421i does not support 3D image projection. Most of the other 3000:1 contrast ratio projectors that were launched more than a year ago also do not support 3D image projection.

Chart Edit

Does Not Support Full HD Projection

Most projectors of this age and type do not support Full HD projection. The EB-421i is no exception to this as it too does not support Full HD projection.

Chart Edit

Very Dim Projector Brightness

Across all the 3000:1 contrast ratio projectors that came out more than a year ago the projector brightness range from 2,500 ANSI lumens to 6,000 ANSI lumens, and the average projector brightness is 3,900 ANSI lumens. At only 2,500 ANSI lumens, the Epson EB-421i has a quite dim projector brightness compared to most of the other comparable spec multimedia projectors that have been on the market for a similar time to the EB-421i.

Data projectors with a brighter projector brightness that might also be worth looking at include the Sony VPL-SX226 (2,800 ANSI lumens).

Very Small Lamp Power

At only 200 Watts, the EB-421i has a quite small lamp power compared to most of the other projectors of this age and spec. Across all the 3000:1 contrast ratio projectors that were launched around the same time as the EB-421i the lamp power range from 200W to 470W.

Chart Edit

Very Dim Brightness in Economy Mode

The average brightness in economy mode of projectors that have been available for around the same time as the EB-421i is 4,200 ANSI lumens, and the brightness in economy mode range from 1,900 ANSI lumens to 15,000 ANSI lumens. At only 2,000 ANSI lumens, the EB-421i has a fairly dim brightness in economy mode compared to most of the other comparable spec data projectors that are a similar age to the EB-421i.

Chart Edit

Very Small Matrix Size

The EB-421i has one of the smaller matrix sizes (only 0.55 inches) amongst 3000:1 contrast ratio projectors of this age. Comparable spec projectors that have been around for a similar time to the EB-421i have matrix sizes of between 0.55" and 0.75".
