Just a warning - running this for a few seconds has left my secondary display with an ongoing flicker which seems to be improving after 10 minutes and a reboot.

yeah that happened here too. Was it an LG?

  Yes! It's an LG Ultra HD running at 2560x1440 @ 60Hz

    Same with an LG running at 2560x1080 Now what is causing it?

    Same monitor here. Damn strange. I'd experiment more if I didn't need to work with it. Keeping the monitor off for awhile seemed to help , but a quick off/on didn't.

      Yup, I turned it off, disconnected it from my Mac and left it for a minute, then rebooted. All seems fine now.

Same here, on a Dell P2421DC (2560 x 1440 @60 Hz). It is especially noticeable on darker colors (grey or black backgrounds).

Same on my Dell. What seems to stop it is turning off HDR and back on again (using the monitor's OSD menu)
