Has a Built-In Speaker(s)
Like most of the other projectors of this age and type, the Optoma S311 has a built-in speaker(s).
We think you might also be interested in some of the alternative projectors with a built-in speaker(s) currently available including the Optoma H100[plb_2040880_price] which has better reviews; or the Optoma H181X[plb_2591464_price] which is cheaper.
Other multimedia projectors which also have a built-in speaker(s) that you might also want to look at include the Optoma X316[plb_2280095_price].
The Optoma S311 supports 3D, as do most of the other similar spec data projectors that have been available for a comparable time to the S311.
Other projectors which support 3D currently available that you might want to look at include the Optoma H100[plb_2040880_price] which has better reviews; or the Optoma H181X[plb_2591464_price] which is cheaper.
We compared all the other projectors which also support 3D to this projector and we think the Optoma X316[plb_2280095_price] is also worth considering.
1600 X 1200 (UXGA) Supported Graphics Resolutions
The Optoma S311 supports a maximum resolution of 1600 x 1200 (UXGA). That's over six times the resolution of a 640 x 480 (VGA) multimedia projector, which is the most common resolution supported by data projectors of this spec and age. 640 x 480 (VGA) is also supported by this projector. In addition, this Optoma projector support supported graphics resolutionss of 1024 x 768 (XGA) and 1280 x 1024 (SXGA) and 800 x 600 (SVGA). Across all projectors that are a comparable age to the S311 the best resolution is 1920 x 1200 (WUXGA) and the worst is 640 x 480 (VGA).
100V AC Input Voltage
This data projector has a 100 - 240V AC input voltage, which is the most commonly found AC input voltage on multimedia projectors of this age and spec.
Data projectors that are a similar age to the S311 have weights of between 2.2g and 26kg. The Optoma S311 is fairly light (only 2 kilograms) compared to most of the other projectors that were released more than two years ago.
8 Reasons Against
Price Increase of £60.00
The S311 has increased in price by £60.00 in the last 45 days.
Does Not Support Full HD
The Optoma S311 does not support full HD, although keep in mind that most of the other projectors of this age and type also do not support full HD.
We think you might also be interested in alternative data projectors which also support full HD including the Optoma H181X[plb_2591464_price].
Does Not Support Wi-Fi
Like most of the other data projectors of a similar age and spec to the S311, the Optoma S311 does not support wi-Fi.
Only SVGA (800x600) Projector Native Resolution
The Optoma S311 has a maximum resolution of SVGA (800x600). That's 77% less resolution than a 1080p (1920x1080) projector, which is the most frequently found resolution.
A SVGA (800x600) projector native resolution is actually the worst resolution across all similar spec projectors that have been on the market for a comparable time to the S311.
The best resolution amongst similar types of projector is 1080p (1920x1080).
