Sanyo PLV Z4 projector review at I4U


Mark Peters : 2006-04-12 23:00:00
Sanyo PLV Z4 projector review at I4U : I4U, the Future Technology News website, has reviewed the Sanyo PLV-Z4 projector. The Sanyo Z4 was launched in 2005 and is the latest multimedia projector for the enthusiastic home cinema r business user. The contrast ratio of the Sanyo PLV-Z4 projector is 7000:1 which gives a very bright white, and at the same time deep black image. To achieve this high contrast ratio Sanyo incorporated a new enhanced technology; twin iris. With the lens the projector is using, a first iris is incorporated which aperture can be set. The smaller the aperture, the higher is the contrast of the image. A second iris is incorporated near by the lamp of the Sanyo PLV Z4 projector.
