Dell Optiplex 7050 Connects with three monitors. Those monitors are the same model (Dell 19 inches).
Dell Optiplex 7050 has three ports (VGA, Displayport, HDMI) for connecting monitors.
Monitor 1 : VGA - VGA
Monitor 2 : Displayport - Displayport
Monitor 3 : VGA - VGA - VGA to HDMI
Three monitors are working fine with extended mode.
But when I tried to duplicate two of monitors, it will pop up unable save display settings message.
Does anyone know why and how to fix this issue? Thank you!
