DataDrake I have 3 Monitors, connected to a MSI Radeon RX 580 card, from left to right they are: A Samsung 1920 x 1080 DVI, 2 Scepter Brand 24" 1920 x 1080 both HDMI, the middle is identified by the OS as HDMI-0 and the right one as HDMI-A-1. Prior to the latest update, after being configured, they stayed that way. Currently, at login to the desktop, the 2 scepter monitors are a mirror of each other. Going to system settings/display & monitors, you see only two, but when you click and grab one of the scepters, you see the other one underneath it, so i have to click and drag it off to the right and click apply, which....is not keep them in that order. So, I click on say, anything else on the settings menu, and it puts up a window "you have unsaved settings, would you like to apply them" and i click yes. so...until i have to reboot, they stay ok. Does this help?
