The projector SRX R815P by Sony utilizes SXRD technology and, according to the spec sheet, achieves 15000 ANSI lumens, a contrast of 10000:1 at a resolution of UHD (4K+2K) 4096 x 2160. The manufacturer lists the lifespan for this model at 35000 hours – calculating to 24 years at four hours of use per day. A major advantage for professional installations is the ability to use interchangeable lenses, allowing the projector to adapt to highly varied projection distances. Which optic is required for a specific case can easily be calculated via the Distance Calculator. Regarding projection size, the value of 15000 ANSI lumens allows for an image width of up to 813 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 542 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. This model dates back to 2017 and is no longer part of Sony's current product range. In our projector directory, the device still generates high interest.
