I have two monitors connected to my PC. When I restart it from Standby my secondary monitor doesnt work anymore. This also happens when I switch to the console and then back to Gnome. How could I fix that?

pm-powersave runs a bunch of scripts when you got into or out of standby. That's probably what's doing it to you. See my answer to Why is wireless down/strange after switching to battery? which MAY help

Still has the same issue even on new Ubuntu. After standby on of monitors not starting up and monitor showing no signal message.

My work around for it (turn off monitors and turn them on after again):

xset dpms force off && sleep 2 && xset dpms force on

But will be good to permanently fix it.

PS: btw - it's happening not each time, just once in a while (probably 1 of 5-6).
