I am a little confused by what you are trying to do (normal for me).I can only speak with certainty for my 29M. I have an hdmi swichbox in my upper cabinet, hopefully you do as well. The switchbox is connected to all 3tvs and has hdmi inputs and three outputs. If you plug the output from your Wally into that switchbox it will feed all of your tvs at the same time. Just make sure you set your tvs to the appropriate hdmi input. Good luck.
