My LG 4K just arrived. I will be posting my impressions here. For various reasons, I am most likely not going to keep it, but I will give it a good test in the coming days. My rMBP is coming tomorrow, and I'll have more to say then. --It's not as ugly as the pictures. The bezel is nicer than my dell--all black, much more minimal logo. The stand is uglier than the Dell's, but it's not as bulky as I thought it would be. The power cable flushes nicely into the case, like the iMac. --The stand can go up and down, but you cannot put the monitor into portrait mode. It supports VESA mounts, though. --It's glossy. Yuck. I much prefer the finish on my P2415Q. But if you are used to an iMac, it will probably not bother you. --I think they really mean it with the USB-C Mac system requirements. There's a huge Mac icon on the box, and hooking up the display to a hackintosh (displayport to USB C) with a GTX 970 does not work. I'm still on 10.12.0, though. I'll try updating to .1 later tonight to see if it makes a difference, and see if Windows 10 can pick it up. --The all-USB C ports (there are four) is a very puzzling decision, especially since Apple billed it as the ultimate dock. If I were to keep it, I'd have USB C to A adapters permanently attacked to the back. --There's a hole in the top of the bezel that looks like a microphone. Unfortunately, the manual is just a useless kickstart guide, so I don't know what it is. Any questions, let me know!
