One of the key features of the Compaq MP4800 is its impressive brightness, rated at around 2000 ANSI lumens.

Additionally, the projector boasts a native resolution of 1024 x 768 (XGA), enabling sharp and clear image quality for both text and graphics.

Ease of use is prioritized in the design of the MP4800. It features a user-friendly interface, with intuitive controls that allow users to quickly adjust settings and troubleshoot issues. The projector is designed for portability, weighing around 5.5 pounds, which allows for easy transport between meeting rooms or to off-site locations.

In terms of durability and maintenance, the Compaq MP4800 features a long-lasting lamp life of approximately 2000 to 3000 hours, depending on usage mode. This results in reduced maintenance costs and less frequent lamp replacements, providing users with more extended periods of uninterrupted use.

With its solid brightness, excellent image quality, versatile connectivity options, and ease of use, it remains a respected choice in environments where quality presentations are essential.
