My year-old 27" iMac running Catalina with an external monitor always comes out of sleep a couple of clicks brighter. This is really frustrating because I calibrate my monitor for photo work so it's very time-consuming. My external monitor stays calibrated but the 5k iMac screen is always brighter after sleep. Any ideas on how to fix it? Thanks!
iMac 27″, macOS 10.14
First, please restart in Safe Mode and then restart normally and retest.
