I have 3 displays which are connected to the same video card (2 DVI and 1 HDMI connection). Named display #1, #2 and #3 from left to right. When I set the Lightroom as second monitor mode, it displays to #1 and #3. I can't select the target display intentionally. I want to use #1 and #2 !!! Are there any way to configure to do so ? Thanks.
Have you tried need to dragging the window you want to the monitor you want? I've used this method to switch LR between the primary and secondary before using this method. It should remember it after that.
