The ViewSonic PX706HD offers a simple panel of inputs and connections on the rear of the unit, but everything you need for your home entertainment/gaming purposes. The A/C Power Cord connects in the bottom left corner of the panel. On the left side, there is a blue Audio In 3.5mm mini-jack port, and below that a green Audio-Out mini jack port, to connect external audio equipment and speakers to the projector.
To the immediate right of the audio ports are the dual HDMI ports for connecting high definition video gaming systems and BluRay players, as well as laptops and other similar media sources. Next is a USB-C port, which provides for fast data, audio, video and charging over a single cable, supporting smart mobile devices. Then we have a VGA port labeled “Computer In” which is useful in connecting PCs for computer gaming on the big screen, an RS-232 port for legacy command and control.
There is also a Mini-USB port for connecting card readers and other media for PC-Free Presentations, and a yellow Component Video (RCA) port for legacy video game systems and other old-school video devices. That’s not a huge amount of connections, but it’s still plenty for the primary use and its price point.
