My macOS High Sierra install keeps switching to 720p HiDPI in stead of running at the native 1440p.
When I click on the 1440p setting it shows me the correct res but it switches back after about 1 second. When I reboot my Mac I also log in with the correct res but it changes to HiDPI after ~5 seconds.
The monitor is from Asus, 27" 2560x1440.
I tried changing the res with SwitchResX and jhford's screenresolution utility.
