The highest resolution of the Viewsonic PJD5226 is XGA (1024x768). That's 62% less resolution than a 1080p (1920x1080) multimedia projector, which is the most common resolution.
This data projector's resolution (XGA (1024x768)) is actually the worst resolution across all projectors that have been available for around the same time as the PJD5226.
A 1080p (1920x1080) native projector resolution is the best resolution across comparable types of data projector.
We compared all the other multimedia projectors that have a resolution of XGA (1024x768) to this data projector and we think a higher scoring projector such as the ZX212ST, and the ZX210ST ($1,619.99) both from Optoma or the Vivitek D517 are also worth considering.
If the resolution of this projector is not high enough for you then you might want to also look at the SA560 (WXGA (1280x800 and higher rated) and higher rated), or the SA565 (WXGA (1280x800 and higher rated) and higher rated) both from LG or the Optoma ZW212ST (WXGA (1280x800 and higher rated) and higher rated).
