CP-X380W specifications

The Hitachi CP-X380W is a versatile and high-performance projector designed to meet the needs of educational and business environments. This model stands out for its impressive features, advanced technologies, and user-friendly characteristics, making it an ideal choice for classrooms, conference rooms, and collaborative spaces.

One of the main features of the CP-X380W is its brightness, boasting an impressive 3,800 ANSI lumens. This level of brightness ensures clear and vibrant images, even in well-lit rooms. The high contrast ratio of 20,000:1 enhances image quality by providing deeper blacks and brighter whites, making presentations visually appealing and easy to read.

The projector utilizes Hitachi’s proprietary BrilliantColor technology, which enhances color reproduction by improving the vividness of colors while maintaining image clarity. This is crucial for presentations that rely heavily on visuals, such as graphs, charts, and images, where accurate color representation plays a significant role.

With a native resolution of WXGA (1280 x 800 pixels), the CP-X380W delivers sharp images and text, making it suitable for detailed content. Its 16:10 aspect ratio is particularly beneficial for displaying widescreen content, providing a cinematic experience during video playback.

In terms of connectivity, the Hitachi CP-X380W offers a range of options, including HDMI, VGA, and USB ports. This allows users to connect various devices such as laptops, tablets, and smartphones easily. The inclusion of wireless networking capabilities further enhances flexibility, enabling presentations from mobile devices without the need for physical connections.

The projector is designed with user-friendliness in mind. Its simplified menu navigation and remote control make operation straightforward, even for those who may not be tech-savvy. The built-in 10-watt speaker enhances audio output, reducing the need for external sound systems in smaller settings.

For maintenance, the CP-X380W features a long lamp life of up to 5,000 hours in standard mode, which can be extended to 6,000 hours in eco mode. This longevity significantly reduces the total cost of ownership by minimizing the frequency of lamp replacements.

In summary, the Hitachi CP-X380W is a robust projector that balances brightness, image quality, connectivity, and ease of use. Its advanced technologies and thoughtful design make it an excellent addition to any educational or professional setting, ensuring impactful presentations that leave a lasting impression on audiences.
