Ask Different (Apple): Dual-Monitor: Second monitor black after sleep mode

I'm using two Elgato Thunderbolt Docks on my MacBook Pro Mid-2012. I connected two displays to them: One HDMI display on each of them. Both are LG-Displays, one a 16:9 and one a 21:9 display.

This configuration works fine - at least sometimes. If it works it works the whole day. If I then put my MacBook into sleep mode and wake it up again some time later, I have two possible results:

Both monitors are picked up just fine and everything works (60% of the time)

Both monitors are recognized, only one (the first connected) actually shows a picture, the second one then has no picture and goes to sleep

I have no consistent behaviour here because I can try whatever I want, PRAM-resets, reboots, deleting display settings etc., I cannot force the second monitor to work, too. It randomly works at some point.

What can I do to fix this or at least force the second monitor to work, too?

Remember: OS X recognizes both monitors with their correct color profile and resolution and often, it DOES work (I use the MacBook in clamshell).

Console output opon connecting the second monitor alone:
