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.
