Behind the name LP-TW4001 is a LCD projector by Hitachi, whose main features include 4200 ANSI lumens, a contrast of 500000:1 and a WXGA 1280 x 800 resolution. The laser technology ensures a specified light source lifespan of up to 20000 hours. Daily use of 4 hours makes an operational lifespan of over 13.7 years possible. 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 60 cm. Looking at practical performance, up to 658 cm can be illuminated with 4200 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 439 cm. For media input, video signals up to 1080P are supported. The built-in HDMI-MHL (Mobile High-Definition Link) port enables screen mirroring from a smartphone while simultaneously charging it. For convenient remote monitoring and administration, the projector is equipped with a classic RJ45 network socket. This model dates back to 2018 and is no longer part of Hitachi's current product range.
