Problem 1, my computer is unable to recognize a second monitor. I believe this is from incorrect drivers.
Problem 2, I am not certain what drivers am I to use but have managed to switch to "video-hybrid-intel-nvidia-430xx-bumblebee" for both GP107M[GeForce GTX 1050 Mobile] and UDH Graphics 620 (Intel Corporation).
Been trying to figure this out for a few days now. Any help is appreciated.
