Slideshow on second monitor - not working
I have my MacBook Pro connected to a BenQ SW271 monitor, used as a second monitor. In dual monitor mode the LR slideshow does not progress on the second monitor, but runs normally on my MacBook. After a frustrating 2 hours with an advisor I have been told there is an incompatability between DPI of BenQ Monitor and MacBook Pro (an assumption I believe). Has anybody esle had this problem and does anyone have any idea how to resolve it?
