ViewSonic Pro8450 with VP3D1 adaptor review


The Viewsonic Pro8450 is a 720p single-chip DLP projector with a variety of applications.

Astonishingly bright picture; good detail for a 720p projector

Blacks and contrast fall short of competition; sample problems

ViewSonic PRO8450W 3D Projector review


Can the ViewSonic PRO8450W projector transcend some of 3D's biggest pitfalls?

Good image quality ; Connections ; 3D compatible

No 3D processor included ; A bit noisy ; 4500 Lumens might be too bright for normal home cinema use
