Moreover, the MP2800 is equipped with built-in speakers, providing a convenient audio solution for presentations and video playback without the need for external speakers. The lamp life of the projector is also commendable, with an estimated lifespan of up to 3000 hours in standard mode, reducing maintenance costs and the frequency of lamp replacements.
