I bought this adapter specifically because it has an HDMI port and 2 Lightning Bolt (USB-C) ports so I can connect external hard drives and an extra monitor . This works well enough BUT my external monitor keeps turning off for a second or two before the image reappears. It probably happens every 5-10 minutes. I've tried this with a few different external monitors and the same thing happens on all of them. Otherwise it's great.
