Admonition

Do not attempt to change any settings on the display, cabling configurations, or placement of hardware. Each of them has a single, specific set of working parameters, and changing one could prevent all the others from working properly.

Step-By-Step Setup Instructions

Note: It is very important to complete these steps in order. Failure to do so will prevent the video system from correctly detecting the video signal, and all you will get is a blank screen.

Open your laptop and plug in your preferred interface cable from one of the three available (HDMI, mini-DP, and DVI).
Make sure the power indicator light on the video switch is lit. If not, turn on the power.
Select the input you are working with (Input 1: HDMI, Input 2: mini-DP, input 3: DVI)
Turn on the video screen, and make sure the green light on the back of the screen is lit.
Send video from your laptop.
Make sure that the video switch correctly identifies the resolution you are sending from your laptop. (Stop here unless you need audio with your video)
If audio is needed, plug the 1/8" audio interface cable into the headphone jack on your laptop, and set the volume on your laptop to 50% of it's maximum setting.
Dial in your predetermined mixer settings. (Start with both the laptop input channel and headphone output channel at 5, and tweak from there.)
When finished, please be sure to turn off the screen power from step #2 above.
