I have two 4k monitors but on my secondary(riglt) moitor my color picker isn't working. It works fine on my primary monitor(left), but as soon as I move it over to my second monitor it starts picking random colors. I usually have my color libaries on my second screen so it's really anoying. Any help would be usefull.
colors are not random it's picking color from your desktop image. You say you usually keep your color libraries on 2nd monitor so that means the problem started suddenly, right? It worked before and now it's stopped? Did it stop working after an update? What settings are you using for multi monitor setup?...try to update video drivers. clear cache reboot. Works on my multi monitor setup
