Eye Dropper/Color Picker hasn't worked on 4K display for years!
Eye dropper color picker in any of the tools or effects has not worked on my 4K monitor for the last 2 years. When I try to pick a color its like it picks a color from somewhere else on the monitor or often picks black. I have to export a still import into photosshop and pick the color there. I have a Sharp PNK321 LCD display with a Apple Cinema Display also connected and mirrored.

Yes I have this problem now with Premiere Pro CC v.14.7.0 but I never had it before with the same system for 2 years. I've found two work-arounds: place all the PP window panes / panels onto the main monitor (Window -> Workspaces -> Editing) or you can right-click on your desktop, select Display Settings, and set scaling (text, icons, and apps) to 100%.
It's because of UI scaling. If you set it to 100%, the issue is resolved.
But then you have a much bigger problem.
Or should I say, SMALLER, har har.
