Hi all. I have a 27" 2016 iMac (late 2015) 5K display and wanting a second monitor... is this possible with my current setup? how does this setup work? Looking for a nice LG monitor, the Apples ones are far too expensive for me right now.. Because my iMac has a 5k display, would it be an issue that the screen I'll be purchasing will not be 5k? I'm looking for a inexpensive LG screen. Thanks all.
