I just installed dual monitors for the first time. I have my Windows 10 Home build 19041.928 computer set to "computer sleep never" (file server), and the display[s] to turn off after 8 minutes. The issue that I have is the secondary display goes to sleep as expected, but the primary display goes "black" but the backlight remains lit and the monitor itself remains active. These are two identical monitors, purchased the same day, and hooked up the same way (display ports on the 2060 video card).

Is there something I need to "redo" for the updated configuration?
