7 Reasons For

Good Brand

We checked 736 expert and user reviews for Epson multimedia projectors and found that on average Epson has good reviews compared to other brands. We also found that Epson has good reviews specifically within its 2000:1 contrast ratio data projectors range.

Has a Built-In Speaker

The Epson EX51 has a built-in speaker. Most of the other multimedia projectors that have been on the market for around the same time as the EX51 also have a built-in speaker.

Fairly Long Service Life of Lamp in Economic Mode

2000:1 contrast ratio data projectors that were released around the same time as the EX51 have service life of lamp in economic mode of between 2,500h and 10,000h, and the average service life of lamp in economic mode is 4,100h. The Epson EX51 has one of the longer service life of lamp in economic mode (5,000 hours) amongst similar spec multimedia projectors of this age.

Narrow

The Epson EX51 is quite narrow (only 294.64 millimeters) compared to most of the other 2000:1 contrast ratio data projectors that have been on the market for a comparable time to the EX51. Data projectors that were released more than two years ago have widths of between 120mm and 540mm.

9 Reasons Against

Does Not Support Full HD Projection

The Epson EX51 does not support Full HD projection. Most of the other comparable spec projectors that are a similar age to the EX51 also do not support Full HD projection.

There are a number of alternative multimedia projectors which also support Full HD projection which you might want to consider including the AAXA Technologies LED Android Pico Projector ($499.00).

Does Not Support 3D Image Projection

The Epson EX51 does not support 3D image projection, although it is worth noting that most of the other 2000:1 contrast ratio data projectors that came out more than two years ago also do not support 3D image projection.

There are a number of other data projectors which also support 3D image projection that you might want to look at including the NEC U310W which also has a higher rating.

Does Not Support WiFi Connectivity

Like most of the other 2000:1 contrast ratio data projectors that were launched around the same time as the EX51, the Epson EX51 does not support WiFi connectivity.

We compared all the other multimedia projectors which also support WiFi connectivity to this data projector and we think the Epson PowerLite 1761W ($649.99), or the AAXA Technologies M2 Micro is also worth considering.
