The DS311 is in the cheapest 13% of all 72 projectors of a comparable age and type that we have looked at for 1 year running costs. Based on average energy prices and usage levels, we estimate the 1 year running cost of the DS311 is only £77.
Optoma Multimedia Projectors Have Good Reviews
On average Optoma 13000:1 contrast ratio projectors have good ratings compared to other brands as do all multimedia projectors built by Optoma.
Supports 3D Image Projection
The Optoma DS311 supports 3D image projection, as do most of the other projectors of a similar age and type to the DS311.
There are a number of other projectors which support 3D image projection currently available which you might also want to consider including the Benq MX522 which has better reviews.
Has a Built-In Speaker
The Optoma DS311 has a built-in speaker, as do most of the other multimedia projectors that have been available for a comparable time to the DS311.
We compared all the other projectors with a built-in speaker to this projector and we think the MX661, and the MS619 both from Benq which has better reviews is also worth considering.
1600 X 1200 (UXGA) Graphics Resolution
This data 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 multimedia projectors of this age and type.
Very High Number of Colours
When compared to other 13000:1 contrast ratio projectors that have been around for more than two years, the number of colours of the Optoma DS311 of 1,073.4 million is one of the highest. The average number of colours of projectors that have been on the market for a similar time to the DS311 is 720M, and the numbers of colours range from 1M to 1,100M.
+5 More reasons for
Fairly Bright Lamp Power in Economic Mode
At 6,500 Watts, the Optoma DS311 has a fairly bright lamp power in economic mode compared to most of the other projectors of a similar spec and age to the DS311. The lamp powers in economic mode of 13000:1 contrast ratio projectors that were released more than two years ago range from 3,000W to 10,000W, and the average lamp power in economic mode is 6,000W.
100V AC Input Voltage
This data projector has a 100 - 240V AC input voltage, which is the most frequently found AC input voltage on projectors of a comparable age and type to it.
The weights of 13000:1 contrast ratio projectors that have been on the market for around the same time as the DS311 range from 1.3kg to 5.4kg, and the average weight is 2.8kg. With a weight of only 2.2 kilograms, the Optoma DS311 is one of the lighter multimedia projectors of a comparable age and spec to the DS311 amongst 13000:1 contrast ratio projectors of this age.
Very Quiet Noise Level in Economy Mode
With a noise level in economy mode of only 26 decibels, the Optoma DS311 has a fairly quiet noise level in economy mode compared to most of the other similar spec projectors that have been available for more than two years. The quietest noise level in economy mode of data projectors of a comparable type and age to the DS311 is 26dB and the loudest is 38dB.
3 Reasons Against
Does Not Support Full HD Projection
Most projectors of a comparable age and type to the DS311 do not support Full HD projection. The Optoma DS311 is no exception to this as it too does not support Full HD projection.
There are a number of alternative data projectors which also support Full HD projection that you might want to look at including the Benq MS504 which is also higher rated.
Does Not Support WiFi Connectivity
Most similar spec projectors that are a comparable age to the DS311 do not support WiFi connectivity. The Optoma DS311 is no exception to this as it too does not support WiFi connectivity.
Quite Small Offset
The Optoma DS311 has one of the smaller offsets (only 115 percent) amongst 13000:1 contrast ratio projectors of this age. 13000:1 contrast ratio projectors that have been available for more than two years have offsets of between 100% and 160%, and the average offset is 120%.

Released Over Two Years Ago
This Optoma data projector has been on the market for over two years.
Average Projector Brightness
The Optoma DS311 has a pretty average projector brightness (2,800 ANSI lumens) compared to most of the other similar spec multimedia projectors that have been available for around the same time as the DS311.
Data projectors with a brighter projector brightness that might also be worth looking at include the Acer X123 (3,000 ANSI lumens).
SVGA (800x600) Native Projector Resolution
The highest resolution of the Optoma DS311 is SVGA (800x600). That's 39% less resolution than the most frequently found 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.
