    I use my 2016 MBP 15" (high end with the Radeon 460) without a monitor at the office, when I get home and connect it to the 5K LG monitor in clamshell mode I will get a blank screen and I will not be able to do anything, it will kind of hang up, and sometimes it will crash. I had similar issues last year with the earlier versions of Sierra, but lately I did not have any problem, Apple fixed it. This week I installed High Sierra Beta 4 and all the same problems started again, any suggestion on how to fix them? I do not want to have to go back to Sierra because I am also already using iOS 11 on my other devices and they sync well with High Sierra, thanks

    It's a RX460 GPU issue—please file a bug report with Apple using Feedback Assistant.
