A projector from Optoma is the HD28HDR, whose 3D-BrilliantColor-DLP model delivers 3600 ANSI lumens, a resolution of HDTV 1920 x 1080 and a contrast of 50000:1. The manufacturer rates the durability of the included lamp at 4000 hours. With two hours of daily operation, this corresponds to a period of 5.5 years. Regarding projection size, the value of 3600 ANSI lumens allows for an image width of up to 610 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 407 cm. In terms of video signals, the device processes resolutions up to Full HD 1080P and 4K as well as 3D, meaning standard Blu-ray formats are processed effortlessly. Regarding noise emissions, the model proves to be exceptionally quiet during operation, producing just 26 decibels. This model dates back to 2020 and is no longer part of Optoma's current product range.
