9 Reasons For

Low Running Costs

The HD91 is one of the cheaper to run multimedia projectors that have been around for more than two years that we have looked at for running costs. Based on typical energy prices, we estimate the HD91 will cost only £52 over 1 year to run.

Optoma Has Good Reviews for Its Projectors

We calculated the average ratings for all Optoma projectors and also specifically for Optoma multimedia projectors and found that in both cases Optoma had good ratings.

Supports Full HD

The Optoma HD91 supports full HD, which is unusual. Most of the other projectors of this type and age do not support full HD.

Other multimedia projectors which support full HD currently available that you might want to consider include the Benq W7000+, the Epson 5020UB, or the Panasonic PTAE7000U which has better reviews.

Supports 3D

Like most of the other projectors of this age and type, the Optoma HD91 supports 3D.

We compared all the other projectors which support 3D to this multimedia projector and we think because of it's better review score, the Benq W7000+ is also worth considering.

1080p (1920x1080) Projector Native Resolution

This multimedia projector has a projector native resolution of 1080p (1920x1080), which is typical of many comparable spec projectors that have been around for more than two years.

Chart Edit

1920 X 1080 (HD 1080) Supported Graphics Resolutions

The Optoma HD91 supports a maximum resolution of 1920 x 1080 (HD 1080). That's over six times the resolution of the most common supported graphics resolutions of 640 x 480 (VGA) (which is also supported by this projector). In addition, this multimedia projector support supported graphics resolutionss of 1024 x 768 (XGA), 1280 x 1024 (SXGA), 1280 x 768 (WXGA), 1366 х 768 and 1600 x 1200 (UXGA) and 800 x 600 (SVGA). Projectors of this age and spec supported graphics resolutionss range from 640 x 480 (VGA) (worst) to 1920 x 1200 (WUXGA) (best).

Chart Edit

Quite Long Service Life of Lamp

At 20,000 hours, the Optoma HD91 has a quite long service life of lamp compared to most of the other data projectors that were launched around the same time as the HD91. The shortest service life of lamp of data projectors that are a similar age to the HD91 is 1,500h and the longest is 30,000h.

Chart Edit

Very Big Optical Zoom

Across all the multimedia projectors that have been on the market for a comparable time to the HD91 the optical zooms range from 1.1x to 1.9x. When compared to other projectors of a comparable spec and age to the HD91 that we have assessed, the optical zoom of the Optoma HD91 of 1.9 times zoom factor is one of the biggest.

Chart Edit

Very Quiet Noise Level (economic Mode)

Across all the multimedia projectors that have been available for more than two years the noise level (economic mode)s range from 20dB to 40dB. At only 23 decibels, the Optoma HD91 has a quite quiet noise level (economic mode) compared to most of the other projectors that were released more than two years ago.

4 Reasons Against

Does Not Have a Built-In Speaker(s)

Most of the other multimedia projectors that came out more than two years ago have a built-in speaker(s), however the Optoma HD91 does not have a built-in speaker(s).

It is worth considering other data projectors which also have a built-in speaker(s) including the Acer H7531D which also has a higher rating.

Very Dim Projector Brightness

The projector brightnesss of multimedia projectors that were launched more than two years ago range from 300 ANSI lumens to 9,200 ANSI lumens, and the average projector brightness is 2,900 ANSI lumens. The Optoma HD91 has a quite dim projector brightness (only 1,000 ANSI lumen) compared to most of the other projectors that were launched around the same time as the HD91.

Alternative 1,000 ANSI lumens brightness data projectors currently available which you might also want to look at include the Vivitek Q7 Plus, or the LG PA1000 which has better reviews.

If you are looking for a projector with a brighter projector brightness then you might want to consider the Optoma HD161X (£964.89) (2,000 ANSI lumens) which also has a higher rating.

Chart Edit
