Acer Aspire VN7-792G with Nvida GeForce 960M and Ubuntu 18.04.2 LTS.
Try to connect to monitor Asus vx239h.
Sometimes it turns out to connect a second screen as an extension of the screen, for example, if you go into console mode and return. It works for a while, when you try to enter Settings, the screen turns off.
I have similar problem.
