LR - view dust removal on 2. monitor

[Andreas]

Hi,

I use LR  CC, try to utilize the monitor of my win 10 laptop 14", plus a 22" Eizo. While I have no problem to change settings on the laptop and see changes on the Eizo (magnifier mode), I dont manage it to see the dust removal view on the larger monitor (the view where you mask the pic in black & white, dust spots get highlighted). I just see the normal/colored pic, if I change e.g. exposure I see the change.

 

Hope I could describe my issue ... does anybody know how to achieve this ?

 

regards, Andreas
