Here are a few things to check why your second monitor may not be turning on or may not be displaying the Nerdio desktop:
- Check the video cables in the back of the main monitor or thin client and make sure they are secure.
- Check the video cables on the second monitor to make sure they are secure.
- Make sure “source” is set correctly on the second monitor. It should be set to the type of cable you currently have plugged in: Blue cable end – VGA, White cable end – DVI, trapezoidal shaped cable – HDMI.
