Display Setting for Multiple Monitors

Intel Multi-Display option enabled: The HDMI port on iGfx card is set as Primary Display. 

NOTE: Under Multiple Displays the only option available is "Extend desktop to this display". Windows Display properties (Screen Resolution) needs to be used for extend mode.  

 
Extend These Displays: This option is recommended when an external monitor is connected to a laptop, and each monitor can display different screen independently to improve user convenience. The relative position of the screens can be set up here. For example Monitor 1 may be set up to be to the left of Monitor 2 or vice versa. This depends on the physical position of the LCD monitor in relation to the laptop.

The horizontal line displayed on both monitors can be based on the laptop or external monitor. These are all adjustable options, and all you need to do is drag the monitor of the main screen to the extended monitor.
