Has a Built-In Speaker
The Optoma S311 has a built-in speaker, unlike most of the other comparable spec projectors that were launched around the same time as the S311 which do not have a built-in speaker.
We compared all the other projectors which also have a built-in speaker to this projector and we think the Optoma S313[plb_2502195_price], or the Infocus IN1142[plb_2279221_price] is also worth considering.

The Optoma S311 supports 3D image projection. Most of the other projectors that were launched more than two years ago also support 3D image projection.
We compared this projector to all the other multimedia projectors with a 3D image projection and we think the Optoma S313[plb_2502195_price] is also worth considering.
1600 X 1200 (UXGA) Graphics Resolution
The highest resolution supported by the Optoma S311 is 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 projectors that are a similar age to the S311. 640 x 480 (VGA) is also supported by this data projector. This multimedia projector also support graphics resolutions of 1024 x 768 (XGA) and 1280 x 1024 (SXGA) and 800 x 600 (SVGA). Across all multimedia projectors that were launched around the same time as the S311 the worst resolution is 640 x 480 (VGA) and the best is 1920 x 1200 (WUXGA).
The average width of projectors that have been around for a similar time to the S311 is 380mm. The Optoma S311 is quite narrow (only 287 millimeters) compared to most of the other projectors of a comparable spec and age to the S311.
The Optoma S311 is fairly light (only 2 kilograms) compared to most of the other similar spec projectors that came out more than two years ago. The weights of projectors of this type and age range from 2.7g to 26kg.

Most comparable spec multimedia projectors that were launched around the same time as the S311 do not support WiFi connectivity. The Optoma S311 is no exception to this as it too does not support WiFi connectivity.
Only SVGA (800x600) Native Projector Resolution
The highest resolution of the Optoma S311 is SVGA (800x600). That's 77% less resolution than the most common native projector resolution of 1080p (1920x1080).
A SVGA (800x600) native projector resolution is in fact the worst resolution across all projectors that are a comparable age to the S311.
Across comparable types of projector the best resolution is 1080p (1920x1080).

Quite Small Matrix Size
The average matrix size of projectors of this spec and age is 0.64". With a matrix size of only 0.55 inches, the Optoma S311 has one of the smaller matrix sizes amongst similar spec data projectors of this age.
