Beamers
Beamers are the underdog in video. But they don't deserve that position. Latest models support HD video in wide screen, and project a screen from 1 to 4 meters wide.
Quality differences
The quality of a beamer is measured with a few important factors (tabel 'Beamer Terms Explained'). Lumen is the strenght of the lamp. Contrast measured in ratio. Noise a beamer produces (to cool down) should be under 29dB.
