Feb 18, 2014 Apparently, the easiest way to fix the flickering on a 15-inch Retina MacBook Pro is to simply switch your Wi-Fi connection to a non-crowded channel – ideally, one that only you are using. Apr 16, 2017  Running macOS Sierra V10.12 on mid 2014 MacBook pro, when I connect my HP 27xw monitor MacBook screen keeps on flickering and external display says 'check cable' I tried connecting other laptop to my external display and it works fine.

When I play many games in full screen mode, the top 2/5 of the screen starts flickering (does not appear to be screen tearing). If I play in windowed mode or borderless window, the problem is gone, but not all games support borderless and windowed mode is hard to play with for some games. There is also no problem when playing a video in fullscreen

This problem has been happening since installation, so I know nothing I've done to windows has caused this
