The highest resolution of the Epson EB-S31 is SVGA (800x600). That's 77% less resolution than the most frequently found native projector resolution of 1080p (1920x1080).
This multimedia projector's resolution (SVGA (800x600)) is in fact the worst resolution amongst all similar spec projectors that are a comparable age to the EB-S31.
A DCI 4K (4096 x 2160) native projector resolution is the best resolution amongst similar types of multimedia projector.
We compared all the other projectors that have a resolution of SVGA (800x600) to this data projector and we think cheaper data projectors such as the Optoma DS346I is also worth considering.
Projectors with a higher resolution that might be worth considering include the Epson EB-U04 (UXGA (1600 x 1200 and cheaper) and cheaper).
