The highest resolution of the EB-G6550WU is WUXGA (1920x1200). That's over two times the resolution of the most frequently found native projector resolution of WXGA (1280x800).
A WUXGA (1920x1200) native projector resolution is in fact the best resolution across all projectors of this age and spec.
Across comparable types of multimedia projector the worst resolution is XGA (1024x768).
We compared all the other projectors that have a resolution of WUXGA (1920x1200) to this projector and we think the Panasonic PT-VZ575 (£1,999.20) which is cheaper is also worth considering.
