I am trying to use an ASUS MB168+(1080p) on ASUS X550LA. I have tried to reinstall the driver a few times, but I get the same problem each time.

When the device is plugged in it shows up with the primary screen content, then after a few seconds it goes black, then maybe starting up again with a weird pattern, blackening and starting one or more times before crashing entirely, while in this process the computer runs exceptionally slowly. I remember the screen worked briefly the first time(through not very responsively or reliably) but then after messing about trying to run an HDMI monitor at the same time it is reliably having the described problem, even with reinstalls.
