The integrated speaker, while small, adds convenience for presentations that do not require elaborate sound setups.

Furthermore, the Sharp PG-A20X boasts a long lamp life, often exceeding 3000 hours in standard mode. This longevity not only reduces the total cost of ownership but also minimizes maintenance frequency, allowing users to focus more on their presentations rather than on equipment upkeep.
