A:Answer Hi Kit.
I understand that you left us this question because you were having doubts about this. This is a Polarized Power Cord, we also have a NON-Polarized version of this product. As far as I could research, it should work. However, to be absolutely sure, please contact Vizio and check if a Polarized cord is the correct option for you.
