Question: My converter is not functioning, what troubleshooting steps should I try?
Answer:

1) Verify power is connected and is providing voltage (check with multimeter if possible)
2) Verify that mini-displayport cable is securely inserted into both the computer and the converter. If possible, also try a different cable.
3) Verify that both monitors are capable of the same resolutions and refresh rates. Or at least support a common resolution & refresh rate.
4) Go to System Preferences Displays. On the display tab, click Gather Windows and verify that all screens are detected. Either the monitor should be listed in one of the windows, or the MDP adapter will be listed.
