The projector PT-TX440 by Panasonic utilizes LCD technology and, according to the spec sheet, achieves 3800 ANSI lumens, a contrast of 20000:1 at a resolution of XGA 1024 x 768. The manufacturer specifies a runtime of 10000 hours for this projector's lamp, achieving a lifespan of 13.7 years when used for 2 hours a day. Should a perpendicular setup to the screen not be possible, the integrated keystone correction (horizontal and vertical) helps to realign the image into a perfect rectangle. With its built-in wide-angle optics, the device belongs to the category of short-throw projectors. An image width of 2 meters is realized from a short distance of 92 cm. Regarding projection size, the value of 3800 ANSI lumens allows for an image width of up to 537 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 358 cm. For media input, video signals up to 1080P are supported. For convenient remote monitoring and administration, the projector is equipped with a classic RJ45 network socket. Since entering the market in 2020, production has been discontinued; the manufacturer no longer actively offers the model.
