12 Reasons For

Good Brand

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

Supports 3D Image Projection

The Optoma EX855 supports 3D image projection. Most of the other similar spec projectors that have been on the market for a comparable time to the EX855 do not support 3D image projection.

There are a number of other data projectors which support 3D image projection currently available that you might want to consider including the NEC U310W[plb_1531485_price] which has better reviews.

Supports Full HD Projection

The Optoma EX855 supports Full HD projection, unlike most of the other multimedia projectors of this type and age which do not support Full HD projection.

We compared this multimedia projector to all the other data projectors which support Full HD projection and we think because of it's better review score, the AAXA Technologies LED Android Pico Projector[plb_3156294_price] is also worth considering.

The Optoma EX855 has a built-in speaker, as do most of the other similar spec projectors that came out around the same time as the EX855.

Chart Edit

Fairly Bright Projector Brightness

The Optoma EX855 has one of the brighter projector brightness (5,500 ANSI lumens) amongst comparable spec multimedia projectors of this age. The average projector brightness of projectors of this type and age is 4,100 ANSI lumens.

Chart Edit

1920 X 1200 (WUXGA) Graphics Resolution

The highest resolution supported by the Optoma EX855 is 1920 x 1200 (WUXGA). That's over seven times the resolution of a 640 x 480 (VGA) projector, which is the most frequently found resolution supported by projectors that have been available for more than two years. In addition, this data projector support graphics resolutions 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).

This projector's resolution (1920 x 1200 (WUXGA)) is in fact the best supported resolution amongst all projectors of a similar age and spec to the EX855.

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