Resolution not supported. - DirecTV

I have three tvs connected to my service one directly and two with wireless genies. Only on one of the genie tvs when I change channels, about 50% of the time I get a black screen with a resolution not supported message. The only way I have found to get out of this screen is to power down this tv and genie a few times. What should I do?

This question, "Resolution not supported.," is about DirecTV channels, programming, equipment, and sports.
