Not only does the flickering occur, but also causes massive audio interference. Plug in any studio monitor to the headphone jack on the new matchbook, and enjoy the noise. Unplug the monitor and all is fine. I question if this monitor will not damage the MacBook. Further to this. If you plug in the Mac power supply the audio interference stops reduces. There is still a slight audible hum. If you work in a studio do not use this monitor. 1k down the drain.
