13 Reasons For
Optoma Has Good Reviews for Its Data Projectors
Optoma multimedia projectors have good reviews on average and across all multimedia projectors Optoma is one of the superior brands.
Only Released Two Months Ago
This projector was only released two months ago. Newer data projectors like this one are likely to have more advanced features.
50Hz AC Input Frequency
This projector has a 50/60Hz AC input frequency, which is typical of many data projectors that have been available for the last year.
Supports Full HD Projection
Unlike most of the other similar spec multimedia projectors that came out in the last year which do not support Full HD projection, the Optoma EH331 supports Full HD projection.
We think you might also be interested in some of the other projectors which support Full HD projection currently available including the Viewsonic Pro7827HD (£623.78) which is cheaper; or the HD27 (£549.00), or the HD28DSE (£638.03) both from Optoma which has a better Rating.
Has a Built-In Speaker
The Optoma EH331 has a built-in speaker, as do most of the other projectors that were released in the last 12 months.
Alternative data projectors with a built-in speaker currently available that you might want to consider include cheaper multimedia projectors such as the Viewsonic PJD7326 (£592.00), or the Benq 9H.JED77.23E.
Alternative multimedia projectors which also have a built-in speaker that you might want to consider include the Viewsonic PJD7525W (£740.98).
Supports 3D Image Projection
The Optoma EH331 supports 3D image projection, as do most of the other multimedia projectors that are a comparable age to the EH331.
It may also be worth considering one of the other data projectors which support 3D image projection currently available including the Viewsonic PJD7326 (£592.00), or the Benq 9H.JED77.23E which is cheaper.
It is worth also looking at alternative projectors which also support 3D image projection including the Viewsonic PJD7525W (£740.98).
+8 More reasons for
1080p (1920x1080) Native Projector Resolution
This multimedia projector has a native projector resolution of 1080p (1920x1080), which is the most frequently found native projector resolution on similar spec projectors that have been around for a comparable time to it.
We think you might also be interested in some of the other data projectors that have a resolution of 1080p (1920x1080) currently available including the Optoma HD28DSE (£638.03) which has a better Rating; or the Benq 9H.JED77.23E which is cheaper.
Two Built-In Speakers
Most of the other latest multimedia projectors only have one built-in speaker, however the Optoma EH331 has two built-in speakers.
Fairly Long Lamp Service Life
Multimedia projectors that have been around for a comparable time to the EH331 have lamp service lives of between 1,500h and 30,000h, and the average lamp service life is 7,600h. The Optoma EH331 has one of the longer lamp service lives (10,000 hours) amongst multimedia projectors of this age.
Quite Quiet Noise Level
The quietest noise level of multimedia projectors that were released around the same time as the EH331 is 22dB, the loudest is 40dB, and the average noise level is 33dB. With a noise level of only 29 decibels, the Optoma EH331 has a fairly quiet noise level compared to most of the other multimedia projectors that are a similar age to the EH331.
If you are not worried about having a louder noise level then you might also want to look at the Viewsonic PJD6552LW (£555.05) (32dB) which is also cheaper.
The average width of multimedia projectors that are a similar age to the EH331 is 380mm, and the widths range from 140mm to 590mm. The Optoma EH331 is one of the narrower similar spec multimedia projectors that are a comparable age to the EH331 (only 298 millimeters) amongst multimedia projectors of this age.
The weights of multimedia projectors that have been available for around the same time as the EH331 range from 2.7g to 28kg, and the average weight is 7.2kg. At only 2.2 kilograms, the Optoma EH331 is fairly light compared to most of the other new similar spec projectors.
Quite Low Power Consumption in Economy Mode
With a power consumption in economy mode of only 187 Watts, the Optoma EH331 has a quite low power consumption in economy mode compared to most of the other multimedia projectors that have been available for around the same time as the EH331. Across all the latest multimedia projectors the power consumption in economy mode range from 0.5W to 850W.
3 Reasons Against
Does Not Support WiFi Connectivity
Like most of the other recently released multimedia projectors, the Optoma EH331 does not support WiFi connectivity.
Quite Small Uniformity
Comparable spec multimedia projectors that have been around for the last year have uniformities of between 70% and 90%, and the average uniformity is 82%. When compared to other multimedia projectors that have been available for around the same time as the EH331 that we have checked, the uniformity of the Optoma EH331 of only 70 percent is one of the smallest.
Only One HDMI Port
Most projectors that came out in the last year have between one and three HDMI ports, including the Optoma EH331 which has one HDMI port.
2 Other reasons to consider the Optoma EH331
OK Running Costs
The average 1 year running cost of the EH331 is £76 based on typical usage levels and energy prices, which is typical compared to the other 51 new multimedia projectors.
Average Projector Brightness
With a projector brightness of 3,300 ANSI lumens, the Optoma EH331 has a pretty standard projector brightness compared to most of the other comparable spec projectors that have been available for a similar time to the EH331.
If you would prefer a brighter projector brightness then you might also want to look at the Viewsonic PJD7525W (£740.98) (4,000 ANSI lumens).

Total running cost over 5 years
Running costs for this projector have been estimated based on other similar projectors. If you know how much electricity and water the Optoma EH331uses then please let us know by entering those figures in the boxes above.
Running this projector over 5 years will generate 0.38 tonnes of carbon dioxide (CO2).
To offset that much CO2 you would need to plant 10 tree seedlings and grow them for 10 years.
