This splitter/extender replaces an older 4K Monoprice splitter and two 2K Monoprice extenders over CAT 6A. It works great. I love have everything in one unit and moving to 4K compatibility. I use the loop function to move 4K signals to a second room and the rest go to four additional rooms that have HD TVs. Also am also using the ability to extract audio signals although I would have used an optical rather than coaxial output if I were designing the unit.
