Congrats and Welcome! If your Axis TV's are similar to my Windsport, there is an HDMI switch located in one of the cabinets. If so, you can plug any HDMI component (such as a DVD player or satellite tuner) into one of the HDMI inputs on the back of that switch. Then, use the remote of each TV to select "HDMI 1" as the INPUT.
I'm sure other Axis owners will know.
