Today it happened to me again and after unplugging and replugging the monitor 10 times it worked!!!
It almost makes me feel it must be a HW issue but:
- I'm using two different displayport adapters (DP to VGA at home DP to HDMI at work)
- it never ever happened during a powering on (have powered up my laptop at least 20 times after this issue begun)
- a reboot *always* fixes the problem (have tried it at least 10 times)
