    You have to connect your computer to the port on the back closest to the center of the monitor - it has an oval printed around the port. Also, be sure that you are using the black cable that came with the monitor.

  • It turns on with your MacBook Pro. There are no controls on the display itself.

  • It took several rounds of plugging in the supplied cable before the monitor finally turned on. But it eventually did.

  • I also could not find an on/off switch but my macbook screen was immediately transferred to the LG when the USB cable was attached. It would be nice if there was an on/off switch, unless the power draw is so minimal? Great monitor otherwise!
