The MH733 has one VGA and two HDMI inputs to support both analog and digital video sources. One HDMI input is MHL-compatible for wired mirroring of your favorite smart device. Its VGA output allows you to daisy-chain multiple projectors or displays to show the same video source. A built-in 10W speaker eliminates the need for a separate speaker system, but the projector also features an 1/8" audio output to connect external speakers. It is controllable via Ethernet or RS-232 and includes a VGA cable and IR remote control.
