I have the 2017 12" Macbook and love it. I am going to get a monitor so I can use it as a desktop at my desk. Will also get the Apple keyboard and mouse. Is High Sierra pretty good now with an external monitor? I want to get this monitor as I like the look of it and it supports charging the Macbook plus providing the video feed over the single USB-C cable. http://www.lg.com/us/monitors/lg-27UD88-W-4k-uhd-led-monitor Anyone know if it will be 60Hz at 4k?
