For those who have legacy equipment that outputs 480i through the composite video port, the P55-F1, P65-F1, and P75-F1 shared composite input is NOT supported…even though Vizio lists it in the User’s Manual specifications as “1 Composite (Shared)” and shows it on the TV. The manual also talks about using the “Wide” remote button for 480i material.
I confirmed this situation in several emails with Vizio tech support and talking with a manager in the “Executive Resolutions Team”. The statement I got from the tech persons and verified by the manager is “The ports we put on this model, is similar to what we would put on other VIZIO models. However, 480i resolution is not supported on ANY of our 4K displays”. I said “but it worked on my Vizio P702ui-B3 4K TV.” And, he said, “But that is a much older model.”
Based on the user’s manual I bought the P75-F1 with expectations of using the composite input to show the setup menu and system status of my Anthem AVM-30 home theater audio processor/pre-amp for changing surround modes and adjust settings on the fly while watching various types of 2K and 4K videos and listening to music with background pictures on the TV. If the TV and manual show the input and talks about 480i it should be supported. Big disappointment.
