This video demonstrates an odd display flickering problem that happens randomly with some MacBook Air and MacBook Pro (Retina) models after updating OS X. Typically the problem demonstrates as a constantly flickering external display that no longer works, or an external display that only shows a noisy picture with randomized on/off flickering between a black screen and a noisy display. This is easy to resolve with an SMC reset, as described in this article on OSXDaily.com :
