This projector is named EW775UTI, originates from Optoma, and its data sheet shows 3500 ANSI lumens, a contrast of 15000:1 and a resolution of XGA 1024 x 768. A special feature is the short-throw lens, which allows the device to be positioned at a very short distance from the screen. According to the data sheet, an image width of 2 meters is achieved from a distance of just 70 cm. Looking at practical performance, up to 515 cm can be illuminated with 3500 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 343 cm. For integration into professional environments, an RJ45 connection is available for network control and remote maintenance. A look at the data sheet confirms a very subtle fan noise for the projector at just 30 decibels. This model dates back to 2013 and is no longer part of Optoma's current product range.
