Out of the blue this morning DF started behaving strangely. When I move from monitor A to monitor B the brightness of monitor A is reduced about 20-30% and monitor B is changed to full brightness. The reverse happens when moving from B to A. There is some DF setting that causes this brightness toggle because the behavior goes away when I stop DF. A reboot did not help. I did use TeamViewer to access my PC from my laptop just prior to starting working on the actual PC. I have been running 9.7.1 Beta4 since 8/19/20.

Hi Owen,

Yes, that did the trick. I just don't understand how that flag was turned on the first place. I had been running v9.7.1 Beta4 for a month now. I did not realize that there was a separate TAB for Monitor Fading. What I did notice is that when I clicked the Monitor Configuration button in the upper right corner of the Settings window, the resulting screen did have a Monitor Fading option, which I toggled without any change. I am all set. Thank you for your help.
