I have a strange problem in Lightroom 5.7.1. I have a new pc and only one monitor. I am not able to see effect of any adjustment that I do on the main window in developer module, however it is visible on the film strip and if I click the 2nd screen option at top left of filmstrip a new window opens and changes are visible there. How to correct it? I have reinstalled LR thrice. Downloaded the full software again from site. Twice deleted the preference file but nothing helped. In addition to this any before/after is also not visible in screen 1. Pictures do not load properly in developer module in the screen 1 (they are faded, like half loaded type)
I would be really grateful for this help.
Thanks a ton in advance.
