Q: How do I back-out of 10.10.2 update, HDMI no longer display, screens blink?

How do I back-out of 10.10.2 update?

 

Since the update I can no longer display when I plug in the HDMI port, causes al the screens to blink, appearing as if its swapping from one display to the others.

 

Please help
