3rd Display is Connected but is Not Active (Second external display)

[fucata]

My laptop is trying to extend the display to 2 monitors but only got 1 work at a time. Monitors are HP LE1901w (VGA) and Asus VP239 (HDMI).

I tried to replug monitor after shutting down  laptop and monitor but it doesn't do any good. 

When both of them plugged in, the HP external monitor will show "VGA Input: No Input Signal".

In Advanced display setting, the Display #3 "isn't active"

How to extend the display to both external monitors?

Thank you for answering this.

When I'm using a docker, can the original HDMI/VGA input from the laptop work at the same time?

So, docker handles 2 external monitors, and the laptop handles 1 external monitor.

Hi,

No, you can only use 2 external monitors from the docking station and your laptop screen (total 3).
