9 Reasons For

Optoma Has Good Multimedia Projector Reviews

We calculated the average reviews for all Optoma projectors and also specifically for Optoma data projectors and found that in both cases Optoma had good reviews compared to other manufacturers.

Supports Full HD

Unlike most of the other data projectors that came out more than two years ago which do not support full HD, the Optoma HD421X supports full HD.

Other multimedia projectors which support full HD currently available that you might want to look at include the W7000+[pl_1403580_price], or the W7500[pl_1995206_price] both from Benq or the Optoma HD30[plb_1915718_price] which has better reviews.

Has a Built-In Speaker(s)

Like most of the other projectors that have been around for more than two years, the Optoma HD421X has a built-in speaker(s).

Other projectors with a built-in speaker(s) currently available which you might want to consider include because of it's better review score, the Acer H7531D[plb_1418806_price].

1080p (1920x1080) Projector Native Resolution

This data projector has a projector native resolution of 1080p (1920x1080), which is the most frequently found projector native resolution on projectors of a similar age and spec to it.

Chart Edit

1600 X 1200 (UXGA) Supported Graphics Resolutions

The Optoma HD421X supports a maximum resolution of 1600 x 1200 (UXGA). That's over six times the resolution of a 640 x 480 (VGA) multimedia projector, which is the most frequently found resolution supported by multimedia projectors of a comparable spec and age to the HD421X. 640 x 480 (VGA) is also supported by this Optoma projector. In addition, this data projector support supported graphics resolutionss of 1024 x 768 (XGA), 1280 x 1024 (SXGA) and 1280 x 720 (HD 720) and 1280 x 768 (WXGA). Across all data projectors that are a similar age to the HD421X the worst resolution is 640 x 480 (VGA) and the best is 1920 x 1200 (WUXGA).

Chart Edit

Very High Number of Colours

When compared to other data projectors that have been on the market for more than two years that we have assessed, the number of colours of the Optoma HD421X of 1,073.4 million is one of the highest. The numbers of colours of data projectors that came out around the same time as the HD421X range from 1M to 1,100M.

Fairly Long Service Life of Lamp

Across all the data projectors of a similar spec and age to the HD421X the service life of lamps range from 1,500h to 30,000h. The Optoma HD421X has one of the longer service life of lamps (6,500 hours) amongst similar spec multimedia projectors of this age.

Chart Edit

Quite Big Offset

With an offset of 116 percent, the Optoma HD421X has one of the bigger offsets amongst data projectors of this age. The offsets of data projectors of this spec and age range from 0.03% to 140%.

2 Reasons Against

Does Not Support Wi-Fi

The Optoma HD421X does not support wi-Fi, although it is worth keeping in mind that most of the other data projectors that have been available for a comparable time to the HD421X also do not support wi-Fi.

We compared all the other data projectors which also support wi-Fi to this projector and we think the Benq GP20[plb_2231335_price] which is also higher rated is also worth considering.

Very Small Bulb Power

Across all the projectors that came out more than two years ago the bulb powers range from 140W to 580W. The Optoma HD421X has a quite small bulb power (only 190 Watts) compared to most of the other multimedia projectors of this age and spec.

2 Other reasons to consider the Optoma HD421X

Released Over Two Years Ago

Optoma released the HD421X over two years ago.

Average Projector Brightness

At 3,200 ANSI lumens, the Optoma HD421X has a pretty average projector brightness compared to most of the other similar spec projectors that have been available for a comparable time to the HD421X.

We compared this projector to all the other 3,200 ANSI lumens brightness data projectors and we think the Optoma S311[plb_2591380_price] which has better reviews is also worth considering.
