Info

When more than one code is being sent, send each command only after the response code for the previous command from the projector is verified.

Note

When the projector is put into the standby mode, a message “Shutting Down. Please Wait.” is displayed for about 20 seconds. At that time, if the “POWR_ _ _1” command is being sent, “ERR” will be returned and this command is not received.

The projector also supports various formats, ensuring compatibility with different media. 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.

In summary, the Sharp PG-A20X projector is characterized by its high brightness, DLP technology, portability, versatile connectivity, and long lamp life. These features make it a reliable choice for anyone looking to deliver impactful presentations in a variety of settings. Whether in the boardroom or the classroom, the PG-A20X stands out as a trusted companion for effective communication.
