From: Jaehyun Chung <jaehyum.chung@xxxxxxx> [Why] We do not currently support ODM plus MPO on only one side of the screen. This unsupported case causes validation calculations to divide by zero due to invalid viewport values. [How] Add stopgap for the validation of ODM plus MPO on one side of screen case.
