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: https://vine.co/v/ehwhK5nJ6q3 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.
