Well I've discovered something, started testing the monitor into standby settings and at 240 Hz it has issues coming out of standby, if I set the refresh rate to 120 Hz it has no problem coming out of standby.
Also when its in standby after several minutes or so the monitor wakes up and goes back to sleep again, just like when the Mac Mini is in sleep mode. I guess all of this probably because the monitor doesn't officially support Mac OS only Windows.
A 120 Hz refresh rate is good enough anyway as I don't play games on the Mac and it's not often that I leave the machine long enough for it to go into standby.
