The basic data of the Optoma EX542 includes 2700 ANSI lumens, a resolution of XGA 1024 x 768 as well as a contrast of 3000:1. The manufacturer rates the durability of the included lamp at 4000 hours, achieving a lifespan of 5.5 years when used for 2 hours a day. Regarding projection size, the value of 2700 ANSI lumens allows for an image width of up to 453 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 302 cm. Regarding signal processing, the model is compatible with incoming 1080P content. For convenient remote monitoring and administration, the projector is equipped with a classic RJ45 network socket. In the specifications, the operating noise is listed at a mere 29 decibels, indicating very quiet cooling. The projector was released in 2009 and is officially no longer distributed by Optoma.
