I had this error earlier last week. I swapped out the hdmi cable + micro hdmi adapter I was using for an HDMI cable with an actual micro-hdmi end and the problem went away. I'm not sure if the error was caused by the adapter I was using or the hdmi cable, but regardless, the purchase of a new cable for $12 solved my problem.
