When I boot Windows 10 via bootcamp, I have experienced very erratic behaviour when I connect the 27'' 5k LG monitor to my 15'' MBP 2016, as follows: Windows will crash outright: and reboot No picture at all will show up on the LG display: and an error message, "USB device not recognized" will appear on the MBP display I will get a picture on the LG display, but with max resolution 1280p Sometimes the problem will only affect one of the thunderbolt 3 ports on the mac, sometimes all of them: i.e. I will get a picture if I connect the LG monitor to one of the ports, but not if I connect it to any of the others The display works flawlesssly during a windows session: with 4k resolution, as it should. I know this is not a hardware or cable issue: since the monitor is working perfectly in MacOS. Windows is updated. Have tried a number of reboots. Reinstalling the AMD drivers in Windows has had no effect on the problem. That could indicate that Windows in itself is the root of the problem. It seems to handle this (new) type of connection poorly? Has anyone else experienced anything similar, and is there a solution to this problem?
