The Vivitek D5185HD has a maximum resolution of 1080p (1920x1080). That's over two times the resolution of a WXGA (1280x800) projector, which is the most common resolution. Across all one year old 12000:1 contrast ratio data projectors the worst resolution is XGA (1024x768) and the best is WUXGA (1920x1200).
We compared this projector to all the other multimedia projectors that have a resolution of 1080p (1920x1080) and we think a better rated product such as the NEC NP-PE401H, the Hitachi CP-DH300 (£534.71), and the Optoma EH503 are also worth considering.
Projectors with a higher resolution that might be worth considering include the WUX-400 (WUXGA (1920x1200 and higher rated) and higher rated), or the WUX-450 (£5,042.06) (WUXGA (1920x1200 and higher rated) and higher rated) both from Canon or the Sony VPL-FH500L (£6,737.89) (WUXGA (1920x1200 and higher rated) and higher rated).
What does "projector native resolution" mean?
