The HP mp3320 digital projector is hard to categorize: it's small and light enough for everyday travel, provides the brightness and sharp focus needed to give a lights-on presentation, and is priced like an entry-level projector. Its 2,400-lumen output is roughly twice that of other projectors, such as the HP mp3135 and the BenQ PB6110. On the downside, the HP mp3320 lacks wireless hardware (which is included on other budget projectors such as the Epson PowerLite 765c), it produces a lot of heat, and its color leans toward yellow.
