HP xb31


Hewlett-Packard's xb31 is a DLP projector that packs a lot of power for its size and weight.

Very good brightness and contrast ; Small and light ; full-featured remote ; Fast start-up

Uneven brightness across screen ; Images are slightly green ; Light leakage ; Slow shutdown

PROS: This machine real has a fast start up, unlike other projectors I've seen. A full featured remote control is ideal for navigation and ease of use. It is really small and light and has a very nice brightness and contrast with vibrant color on it!...
