Lenovo Windows 8.1
Plugable 3.0 Dual Monitor Dock
Single HDMI monitor attached to dock
When I close the lid of the laptop the laptop’s screen remains active. The backlight turn off, but display is still active. With other laptops, usually running Windows 7, when the laptop screen is closed the screen is no longer active and any content is pushed to one of the connected monitors.
When the single monitor is connected to laptop’s own HDMI connection and the lid is closed the laptop’s monitor is no longer active, it is only when the monitor is connected through the dock that is does not work correctly.
