I'm thinking of getting a monitor for my MacBook (early 2015, 1.3GHZ, M), and I'm looking at the LG 27UD68; it's on sale right now at Amazon/B&H for $349, (http://amzn.to/2gsSe2z), which is a great deal. I don't think the price will go down any lower in the near future. I'd prefer to get the 27UD88 version, but it's too pricey. Does anyone have their MacBook attached to this monitor? What do you think of it? Would I need to buy a dongle in order for the MacBook to connect to the monitor?
