Optoma has good average reviews for its 13000:1 contrast ratio projectors as well as across its entire multimedia projector range compared to other manufacturers.
Supports 3D Image Projection
Like most of the other data projectors of a comparable age and spec to the DS311, the Optoma DS311 supports 3D image projection.
Has a Built-In Speaker
The Optoma DS311 has a built-in speaker, as do most of the other data projectors that are a comparable age to the DS311.
It may also be worth considering one of the alternative projectors with a built-in speaker currently available including because of it's better review score, the MS619, or the MS504 ($308.99) both from Benq.
1600 X 1200 (UXGA) Graphics Resolution
This projector supports a graphics resolution of 1024 x 768 (XGA)|1280 x 1024 (SXGA)|1600 x 1200 (UXGA)|640 x 480 (VGA)|800 x 600 (SVGA), which is typical of many data projectors of this age and type.
Very High Number of Colours
The numbers of colours of 13000:1 contrast ratio projectors that have been on the market for a similar time to the DS311 range from 1M to 1,100M. The number of colours of the Optoma DS311 of 1,073.4 million is one of the highest amongst comparable spec projectors that have been on the market for a similar time to the DS311.
Quite Bright Lamp Power in Economic Mode
The dimmest lamp power in economic mode of data projectors of a similar age and type to the DS311 is 3,000W, the brightest is 10,000W, and the average lamp power in economic mode is 6,000W. The Optoma DS311 has one of the brighter lamp powers in economic mode (6,500 Watts) amongst comparable spec data projectors of this age.
+6 More reasons for
Quite Big Uniformity
With a uniformity of 85 percent, the Optoma DS311 has one of the bigger uniformities amongst similar spec data projectors of this age. 13000:1 contrast ratio projectors that were released more than two years ago have uniformities of between 80% and 130%.
100V AC Input Voltage
This projector has a 100 - 240V AC input voltage, which is the most commonly found AC input voltage on similar spec projectors that were released more than two years ago.
Fairly Long Lamp Service Life
The Optoma DS311 has a fairly long lamp service life (4,500 hours) compared to most of the other 13000:1 contrast ratio projectors that are a comparable age to the DS311. Across all the comparable spec projectors that are a similar age to the DS311 the lamp service lives range from 2,500h to 20,000h.
At only 2.2 kilograms, the Optoma DS311 is quite light compared to most of the other projectors of a comparable age and spec to the DS311. Data projectors that are a comparable age to the DS311 have weights of between 1.3kg and 5.4kg.
Quite Quiet Noise Level in Economy Mode
The quietest noise level in economy mode of 13000:1 contrast ratio projectors that have been around for more than two years is 26dB and the loudest is 38dB. When compared to other multimedia projectors that were released around the same time as the DS311 that we have assessed, the noise level in economy mode of the Optoma DS311 of only 26 decibels is one of the quietest.
2 Reasons Against
Does Not Support Full HD Projection
Like most of the other data projectors of this spec and age, the Optoma DS311 does not support Full HD projection.
There are a number of alternative projectors which also support Full HD projection which you might want to consider including the MS504 ($308.99), or the MX505 both from Benq which also has a higher rating.
Does Not Support WiFi Connectivity
The Optoma DS311 does not support WiFi connectivity, although it is worth noting that most of the other 13000:1 contrast ratio projectors that have been on the market for around the same time as the DS311 also do not support WiFi connectivity.
3 Other reasons to consider the Optoma DS311
Released Over Two Years Ago
It was over two years ago when Optoma released the DS311.
Average Projector Brightness
With a projector brightness of 2,800 ANSI lumens, the Optoma DS311 has a relatively standard projector brightness compared to most of the other comparable spec data projectors that have been around for more than two years.
SVGA (800x600) Native Projector Resolution
The Optoma DS311 has a maximum resolution of SVGA (800x600). That's 39% less resolution than the most common native projector resolution of XGA (1024x768).

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 DS311uses 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.
