Both projectors come equipped with a comprehensive connectivity suite, including HDMI, VGA, S-Video, and composite video inputs, ensuring compatibility with a wide range of devices such as laptops, DVD players, and gaming consoles. They also feature built-in speakers that deliver clear audio without the need for external sound systems, making them convenient for quick setups.
