Hello,

I recently got a U2718Q and aside from the glitches, it's a great monitor. There was an issue with the colour green which I fixed through a firmware update (currently M2B102).

The problem that started yesterday is that the monitor won't wake up from sleep unless I unplug it for a minute and then try again. It's connected to a MacBook Pro (mid-2014) via the supplied DisplayPort cable. This started happening randomly a few days after the firmware update and no update has been made to the MacBook. 

Is there any thing I can try here or is it better just to return this model? 

Thanks,

Harv
