Are you using some kind of adaptor between HDMI and DisplayPort? I
wonder if this monitor needs proper DisplayPort for multi-stream.

Bug description:
I have an LG ultra-wide (2560x1080) monitor.
Sometimes when I plug it into my laptop, whose screen was working fine
before I plugged it in, both screens go black but nothing else
happens. I can still see the mouse cursor and move it between the two
monitors (sometimes in the correct location configuration I've
configured, sometimes not), but nothing is rendered on the screens.
Sometimes when I plug the monitor in, it comes on, but the resolution
is wrong.
Sometimes it is actually recognized and configured correctly.
Frequently I have to unplug the monitor and plug it back in three
times or more before it is recognized correctly.
I wish it just worked right the first time. :-/
