12 Reasons For

Optoma Has Good Reviews for Its Multimedia Projectors

Optoma is one of the better rated projector brands according to average user and expert review score data that we have collected for all projectors.

Supports 3D

Unlike most of the other comparable spec data projectors that came out more than two years ago which do not support 3D, the Optoma EX855 supports 3D.

Alternative projectors which support 3D currently available that you might want to look at include because of it's better review score, the NEC U310W[plb_1531485_price].

Supports Full HD

The Optoma EX855 supports full HD, which is unusual. Most of the other projectors of a similar type and age to the EX855 do not support full HD.

It may also be worth also looking at one of the other multimedia projectors which support full HD currently available including the AAXA Technologies LED Android Pico Projector[plb_3156294_price] which has better reviews.

Chart Edit

Fairly Bright Projector Brightness

At 5,500 ANSI lumens, the Optoma EX855 has a quite bright projector brightness compared to most of the other 2000:1 contrast ratio data projectors that have been on the market for more than two years. Across all the projectors of a comparable age and spec to the EX855 the projector brightnesss range from 110 ANSI lumens to 10,000 ANSI lumens, and the average projector brightness is 4,100 ANSI lumens.

1920 X 1200 (WUXGA) Supported Graphics Resolutions

The highest resolution supported by the Optoma EX855 is 1920 x 1200 (WUXGA). That's over seven times the resolution of the most common supported graphics resolutions of 640 x 480 (VGA). In addition, this multimedia projector support supported graphics resolutionss of 1024 x 768 (XGA), 1280 x 1024 (SXGA), 1280 x 720 (HD 720), 1280 x 768 (WXGA), 1400 x 1050 (SXGA+) and 1600 x 1200 (UXGA) and 800 x 600 (SVGA).

A 1920 x 1200 (WUXGA) supported graphics resolutions is in fact the best supported resolution across all multimedia projectors of a comparable spec and age to the EX855.

A 640 x 480 (VGA) supported graphics resolutions is the worst supported resolution amongst comparable types of projector.

Very Big Bulb Power

Across all the projectors of this spec and age the bulb powers range from 170W to 4,000W. At 4,000 Watts, the Optoma EX855 has a very big bulb power compared to most of the other data projectors that have been on the market for a similar time to the EX855.

Three Component Video (YPbPr/YCbCr) Ins

The Optoma EX855 is a three component video (YPbPr/YCbCr) in projector. Most of the other 2000:1 contrast ratio data projectors that have been around for a similar time to the EX855 only have between one and two component video (YPbPr/YCbCr) ins.

Chart Edit

Very Big Uniformity

The uniformity of the Optoma EX855 of 95 percent is one of the biggest amongst projectors of this type and age. The smallest uniformity of similar spec data projectors that were released more than two years ago is 78% and the biggest is 95%.

Chart Edit

Three Audio (L,R) Ins

The Optoma EX855 has more audio (L,R) ins than most of the 2000:1 contrast ratio data projectors that have been around for a comparable time to the EX855.

7 Reasons Against

Does Not Support Wi-Fi

The Optoma EX855 does not support wi-Fi. Most of the other comparable spec projectors that have been around for around the same time as the EX855 also do not support wi-Fi.

We compared all the other multimedia projectors which also support wi-Fi to this projector and we think the Epson PowerLite 1761W[plb_1735741_price], or the AAXA Technologies M2 Micro[plb_1759924_price] which also has a higher rating is also worth considering.
