The new PT-TW231RU short throw LCD projector with WXGA resolution (1,280 x 800) and 2,500 lumens of brightness is ideal for classrooms or offices. It has been designed with a short focal lens that allows the device to project a 1.3 m wide image from a mere 65 cm (2.13ft) away from the display surface. This installation flexibility prevents the projector's light from shining into a presenter's face, causing potential unwanted disruption. Minimal maintenance is necessary thanks to a long lamp life and a durable multi-layered filter, both with a replacement cycle of up to 4.000 hours. Built-in interactive feature enables users to project onto surfaces and interact without a specialized board.
