I'm using Fedora 27 and have a 4K display hooked up via display port. Whenever the laptop boots up the resolution (3440x1440) and display detection overall is just fine. However, when the the laptop is suspended and resumes from suspension the max resolution of the display is now only 2560x1080. The resolution 3440x1440 is no longer an option. How can I fix this or quickly re-detect the resolution modes for the display?

The laptop I'm using is a Dell Precision 5520 with both Intel and Nvidia graphics chips.

Thanks for your help!
