The highest resolution of the Optoma S313 is SVGA (800x600). That's 53% less resolution than a WXGA (1280x800) multimedia projector, which is the most frequently found resolution.
This projector's resolution (SVGA (800x600)) is in fact the worst resolution across all data projectors that were released more than a year ago.
Across similar types of projector the best resolution is 1080p (1920x1080).
We compared this data projector to all the other multimedia projectors that have a resolution of SVGA (800x600) and we think the Optoma S311 which has a better Rating is also worth considering.
Projectors with a higher resolution that might also be worth looking at include the Optoma W310 (WXGA (1280x800)).
