10 Reasons For

Low Running Costs

The HD91 has an average 1 year running cost of only £52 based on typical energy prices, which makes it one of the more economic to run projectors that were released more than two years ago.

Optoma Has Good Reviews for Its Projectors

Optoma is one of the better rated data projector brands according to average expert and user reviews, and Optoma also has good ratings for its projectors.

Supports Full HD Projection

The Optoma HD91 supports Full HD projection, which is unusual. Most of the other similar spec projectors that have been available for a comparable time to the HD91 do not support Full HD projection.

We compared this projector to all the other projectors which support Full HD projection and we think because of it's better review score, the Benq W7000+[plb_1403580_price], and the Optoma HD25[plb_1883129_price] is also worth considering.

Supports 3D Image Projection

Like most of the other projectors that have been around for more than two years, the Optoma HD91 supports 3D image projection.

There are a number of other data projectors which support 3D image projection currently available which you might also want to look at including the Benq W7000+[plb_1403580_price] which has better reviews.

1080p (1920x1080) Native Projector Resolution

This data projector has a native projector resolution of 1080p (1920x1080), which is typical of many projectors that are a similar age to it.

Chart Edit

1920 X 1080 (HD 1080) Graphics Resolution

The highest resolution supported by the Optoma HD91 is 1920 x 1080 (HD 1080). That's over six times the resolution of a 640 x 480 (VGA) projector, which is the most frequently found resolution supported by projectors of a similar type and age to the HD91. 640 x 480 (VGA) is also supported by this data projector. In addition, this multimedia projector support graphics resolutions 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). The worst resolution of all similar spec projectors that are a comparable age to the HD91 is 640 x 480 (VGA) and the best is 1920 x 1200 (WUXGA).

Chart Edit

Quite High Number of Colours

At 1,073.4 million, the Optoma HD91 has a quite high number of colours compared to most of the other data projectors of this spec and age. The lowest number of colours of projectors that are a comparable age to the HD91 is 1M and the highest is 1,100M.

Chart Edit

Fairly Long Lamp Service Life

Across all the similar spec multimedia projectors that have been around for around the same time as the HD91 the lamp service lives range from 1,500h to 30,000h. At 20,000 hours, the Optoma HD91 has a fairly long lamp service life compared to most of the other projectors that were released more than two years ago.

Chart Edit

Very Big Optical Zoom

The optical zooms of multimedia projectors of this age and spec range from 1.1x to 1.9x. When compared to other projectors that were released around the same time as the HD91, the Optoma HD91's optical zoom of 1.9 times zoom factor is one of the biggest.

Chart Edit

Very Quiet Noise Level in Economy Mode

With a noise level in economy mode of only 23 decibels, the Optoma HD91 has a quite quiet noise level in economy mode compared to most of the other projectors that came out around the same time as the HD91. Across all the projectors that have been on the market for around the same time as the HD91 the noise levels in economy mode range from 20dB to 40dB.

Chart Edit

5 Reasons Against

Does Not Have a Built-In Speaker

The Optoma HD91 does not have a built-in speaker. Most of the other projectors that were released more than two years ago also do not have a built-in speaker.

We compared this multimedia projector to all the other projectors with a built-in speaker and we think the Acer H7531D[plb_1418806_price] which also has a higher rating is also worth considering.

Does Not Support WiFi Connectivity

The Optoma HD91 does not support WiFi connectivity. Most of the other data projectors of this type and age also do not support WiFi connectivity.

It is worth also looking at other data projectors which also support WiFi connectivity including the LG PW700[plb_2778836_price], or the Optoma W305ST[plb_1726307_price].

Very Dim Projector Brightness

At only 1,000 ANSI lumen, the Optoma HD91 has a quite dim projector brightness compared to most of the other projectors of a similar age and type to the HD91. Across all the data projectors that are a comparable age to the HD91 the projector brightness range from 300 ANSI lumens to 9,200 ANSI lumens, and the average projector brightness is 2,900 ANSI lumens.

There are a number of other 1,000 ANSI lumens brightness multimedia projectors currently available that you might want to consider including because of it's better review score, the PF80[pl_2006601_price], or the PA1000[pl_2417081_price] both from LG.

Projectors with a brighter projector brightness that might also be worth looking at include the Sony VPL-HW40ES[plb_3286333_price] (1,700 ANSI lumens), or the Epson EH-TW7200[plb_3059146_price] (2,000 ANSI lumens) which also has a higher rating.
