I just tried this EP728 in the multipurpose room, which has about 120 people and has a lot of Windows. I closed the blinds, but just left a large part of the Optoma EP728 surrounding Prices - DLP projector light in the room to see how the film brilliant. The painting was large by default, as in the sharpness and brightness. I was very satisfied with the simple connection of the camera to the DVD home theater system with S-video connections. I always thought DVI - HDMI, but he decided after the film, which was not necessary. Great car at a reasonable price. I could not get it when you buy Optoma EP728 - DLP projector at the best price is above $ 800.00.

I teach photography workshop, so I need a high resolution projector, and I see I buy LCD projectors or DLP projector. Optoma EP728 I - DLP projector for the price of Best Buy's love of bright color LCD, but I am impressed SharpNES resolution DLP. So, it is difficult to decide.
I already try another brand Benq come to my first choice. Then, Epson, Toshiba. Infocus, Acer, but none of them did not satisfy my need, but when I try nearly 727 EP satisfies me, but if I compare with the EP 728, there is a big difference, details and color almost perfectly.
So, on reflection, it is difficult, I decided to go to EP 728, although I must pay Optoma EP728 - DLP projector with a value of more than about $ 200. And now I regret it so.
