--- Comment #5 from Andreas Galauner <andreas at galauner.de> ---
I'm experiencing the same issue on a PA328Q connected via DisplayPort.
It must be doing something weird with the HPD line.

When the monitor comes out of standby it is not detected by my stock GNOME 3
environemnt. I have to manually turn if off and on again to use it properly.

Seems like all newer ASUS monitor seem to be affected by this behaviour.

I'm on drm-intel-nightly which is currently based on 4.11-rc5.
