Hi,
I am using an ACER ED270UP external monitor. The monitor works unreliably, sometimes it works on the first try, but generally I have to unplug and plug until it works. It is always detected, but it doesn’t show any signal. When it works, it never stops working until I set my computer to sleep or turn it off.
Here is my xrandr output:
