The highest resolution of the EMP-1717 is XGA (1024x768). That's 23% less resolution than the most common native projector resolution of WXGA (1280x800).
We compared this multimedia projector to all the other projectors that have a resolution of XGA (1024x768) and we think a higher rated product such as the P1283 (£369.99), and the S1212 both from Acer or the NEC NP610 are also worth considering.
If the resolution of this projector is too low for you then you might want to consider the W770ST (£460.02) (WXGA (1280x720 and higher rated) and higher rated), or the W750 (£427.98) (WXGA (1280x720 and higher rated) and higher rated) both from Benq or the Casio XJ-A246 (WXGA (1280x720 and higher rated) and higher rated).
