I have 2 EIZO screens via Thunderbolt/Display port connected to my MacPro (2013 cylinder).
One day I press a key and the screen comes on straight away after sleep, the other day it can easily take 20-30 seconds. I can not find any pattern.
I'm pretty sure the mac self wakes-up, its just the signal to the screens that is in some cases delayed.
Anybody an idea what might to cause that?
Thanks!

Note: When you log back in you may need to readjust some of your system preferences (e.g. speaker volume, screen resolution, startup disk selection, time zone information, etc).

Now use your Mac Pro as usual to determine if the problem still occurs. If so, try using your Mac in Safe Mode for a while to see if the problem occurs.
