ED-X42 specifications

The Hitachi ED-X42 is a highly regarded projector designed to meet the diverse needs of both educational and corporate environments. Combining advanced technology with user-friendly features, the ED-X42 stands out for its versatility and performance.

One of the main features of the Hitachi ED-X42 is its impressive brightness, rated at 4200 ANSI lumens. This high brightness level ensures that images and presentations remain clear and visible even in well-lit rooms. Additionally, the projector boasts a native XGA resolution of 1024 x 768, delivering detailed and sharp visuals that enhance the viewing experience.

The ED-X42 employs a 3LCD technology, which allows it to produce vibrant and accurate colors. This technology ensures that color reproduction is consistent and enhances the overall quality of the projected images. Coupled with a contrast ratio of 2000:1, the projector provides deep blacks and bright whites, ensuring that both text and images stand out.

Another noteworthy characteristic of the Hitachi ED-X42 is its comprehensive connectivity options. The projector features multiple input sources, including HDMI, VGA, and composite video, making it compatible with various devices such as laptops, Blu-ray players, and document cameras. This versatility is particularly beneficial in a classroom or meeting room setting, where different users may need to connect their devices.

The ED-X42 is also equipped with integrated audio capabilities, featuring built-in speakers that deliver clear sound without the need for external speakers. This makes it suitable for small to medium-sized venues where additional audio equipment might not be feasible.

Furthermore, the projector includes a relatively short throw ratio, allowing it to project large images from a short distance. This feature is particularly useful in smaller rooms where space is limited, enabling users to maximize the available area while still achieving a large image size.

In terms of maintenance, the Hitachi ED-X42 utilizes a long-lasting lamp that can operate for approximately 5,000 hours in normal mode and up to 10,000 hours in eco mode. This extended lamp life reduces the frequency and cost of replacements, adding to the projector's overall value.

Finally, the ED-X42 is designed with user-friendly features such as an intuitive remote control and an easy-to-navigate menu, making setup and operation straightforward for users of all skill levels. With its combination of advanced technologies, practical features, and robust performance, the Hitachi ED-X42 remains a popular choice for a wide range of applications.
