Introduction

Up until now I have found that most “dual use” projectors are more designed for the office or school and not so much for the home theater. In the case of the Optoma EP1690, we may have found the first unit capable of actually performing well in both situations. We can place the thanks for this partly on Optoma and partly on the advancement of DLP front projection technology which allows for greater contrast, better output levels and performance options not found a couple years ago. I’ll outline the strengths and weaknesses of the EP1690 below, but I have to say that I am impressed overall and I could see a lot of office managers and teachers wanting to take this unit home from the classroom each night “for safe keeping”.
