Hello, I have a gaming setup with over 35 different consoles hooked up at once. Running to switch boxes and going to my Onkyo 9.2 receiver and 4K Samsung TV. Some of the games like Duck Hunt and other light gun games require a tube TV to work. I have a tube TV next to the setup and would like to mirror the image of what ever game system I am playing without having to hook it directly up to the tube TV. There used to be a rca port on older receivers labeled Monitor Out, but I have not seen it in a long time. I know you can split the HDMI to 2 HD TVs, can it be done to a Tube TV as well? Thanks for the help.
