Hi Christopher, I updated the BIOS as you mentioned and it still does
not improve the situation.

There is a lag both in the mouse movement and the appearance of typed
text that occurs only on my external monitor. On the built-in display
there is no lag at all.

This is a video of what goes on the external monitor:

When I tried to use the nvidia proprietary driver, I am not able to
detect the built-in monitor for some odd reason.

Thank you very much for your help.

Kind Regards
Maka

Title:
  Using displayport with external monitor flickers laptop screen

Status in xorg package in Ubuntu:
  Confirmed

Bug description:
  Using a displayport link to connect with my external monitor causes
  heavy flickering on my laptop screen. Especially when the external
  monitor is being used. There is also a delay of refresh on the
  external monitor... I can see my mouse appear multiple times when I
  move the cursor.
