TV's not in sync - DirecTV

I have 3 TV's in a pool house, all with their own Genie. Only 1 line is coming into the pool house and then it is split and goes to the receivers. All 3 are out of sync. Unacceptable when watching a single sporting event, playoff game, or the Super Bowl. How can this be remedied. Thanks.
