Érdeklődöm, hogy az Epson EB-990U projektor alkalmas-e arra, hogy esetenként függőleges optikai tengellyel működtessük. Nevezetesen térkép vetítésére is szükségünk van vízszintes felületre, pl. aszatalra vagy padlóra helyezett vetítővászonra.

The Epson EB-990U projector delivers clear, extra-sharp images at WUXGA resolution. It is powerful and offers a rich selection of analogue and digital options to connect to a range of input sources, allowing use in multiple rooms of different configurations. Features such as 1.6x optical zoom and automatic vertical keystone correction simplify and accelerate the installation of the projector. With its affordable price, the Epson EB-990 is the perfect imaging tool for companies, schools and other institutions with a lot of viewers.
The practical direct on/off feature delivers an instant image experience without waiting and a longer lamp life. The 3800 ANSI lumens light output guarantees vibrant colours and great-looking images in any environment. The Epson EB-990U projector's lamp boasts a lifespan of up to 6000 hrs despite its high luminosity in normal mode. In ECO mode, the lamp can last up to 12,000 hrs.
A video signal connection is possible across the range of connectors used, including standard D-Sub, composite cable and a pair of digital HDMI including one with MHL support for mobile devices. With the 3-in-1 USB display function, you only need one cable for picture, sound, and page up/page down control. The projector also features an RS-232 or network card for remote management and 16W speakers that deliver loud sound.
Epson is a technology company based in Japan. It is a subsidiary of the Seiko Group, and on of the most important manufacturers of printers, scanners and multimedia projectors. The company's offerings are much broader though, encompassing industrial robots, cash registers, and more.
