The highest resolution of the Canon S-300 is SVGA (800x600). That's 53% less resolution than the most common native projector resolution of WXGA (1280x800). Across all multimedia projectors that have been around for more than two years the best resolution is DCI 4K (4096 x 2160) and the worst is nHD (640x360).
We compared this data projector to all the other data projectors that have a resolution of SVGA (800x600) and we think because of it's better review score, the Optoma S316 (£199.00), and the Acer P1173 (£229.99) is also worth considering.
If the resolution of this Canon multimedia projector is not high enough for you then you might want to look at the Acer H5380 (£349.99) (WXGA (1280x720)) which also has a higher Rating.
