So, I'm running a Dell S2417DG display with my XPS 15 9560 on Windows 10 (latest build, non-insider).
My display works perfectly when it's at 120hz or below, but running at 144 or above causes extreme flickering. I've tested the monitor and displayport cable with other PCs and have no issues whatsoever above 120hz.
I'm thinking it might be a driver issue with the Intel GPU? But I'm not sure what's happening. When I first got the display, it was perfect and started doing this randomly one day. It was set to 144hz with no issues, then it started the next day until I go down to 120hz.
