When my thumbnails are on the second monitor they are not looking like they are color managed. When I move it to the main screen (iMac) they are and look great. If I enlarge them from the second monitor (Dell) to the iMac the enlarged version is color managed. Occasionally if I click on a thumbnail it will pop over to color managed. All the issues are showing on the dell 27" monitor and only with PM, if I open up an image with preview it displays as color managed on both screens.
System info: 2017 iMac 4.2, 40 gigs of ram, Radeon 580 w/8 gigs of memory. Both monitors are calibrated with i1 Pro.
Ideas?
