| Model Overview |
Based on DLP technology, the Optoma H57 device delivers 1100 ANSI lumens, a resolution of WPAL 1024 x 576 and a contrast of 3000:1 as a projector. The manufacturer specifies a runtime of 2000 hours for this projector's lamp. The image geometry can be adjusted via the built-in keystone correction so that a clean, rectangular display is achieved even with non-ideal placement. A look at the light output reveals: The 1100 ANSI lumens are sufficient to illuminate an image width of up to 337 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 225 cm. With a value of only 28 decibels, the noise level during operation remains pleasantly in the background. Since entering the market in 2004, production has been discontinued; the manufacturer no longer actively offers the model. |
