Fixed broken macOS Sierra

After installing the beta and eventually GM version of Sierra, the resolution for my external Dell P2715Q monitor wouldn’t consistenly display properly. Before the upgrade, I was able to use 2550x1440. However, after the upgrade I was only able to get 4K or 1080p resolutions to work consistently. There are some workarounds but they seemed temporary at best. I installed Display Menu and easily can select many different resolutions supported by my monitor. Thanks team, great work!
