2. Connect power and cables. Connect the power cord. Then connect the cables your setup needs (Inputs: 3x HDMI, DisplayPort, 1x USB-A, RJ45, RS-232C). Long runs may need the manufacturer's extender.

3. Update the firmware. Update to the latest firmware before you go live. See Updating the firmware below.

4. Check the picture. Connect the source, check the input switches automatically, and look at the picture from the farthest seat for glare and readable text.
