These are the names for the two types of connections we support. Here's what they look like:
Is the cable plugged into your device all the way?
Is the cable plugged into the port in the wall plate all the way?
Is your device video output actually enabled? (On Windows computers, try pressing the Windows key on the keyboard and the letter "P" at the same time, and choose "Duplicate")
Turn off your device's power save and monitor sleep functions (look in your device's settings or control panel)
