    With the recent update comes an 'HDR' setting, in displays settings. The new HDR setting is on, by default.
    My external monitor (LG 27UK850-W 27" 4K Ultra HD IPS, HDR) looks like its on acid. Colours have turned fluorescent and there's a cast across everything. Apple have had a couple of reports of this bug and are looking into it...If an external display is essential, don't update just yet!

    Thanks for the tip. By the way, I assume the display issue only lasts while connected to your Mac running the latest macOS version?

    yes, and it was perfect on that till the update. Apple have acknowledged it's the new HDR setting. It seems that really, it shouldn't be on as default because (I assume) all but the most recent most expensive monitors will not support it, and cause problems.

    Agreed, but it’s not uncommon for Apple to enable the latest features by default. Still, I hope they resolve the issue fairly quickly for you, sir.
