I'd like to use an ethernet HDMI extender to allow me to feed content and control of a back stage projector for rear projection on stage from a control booth at rear of house. Cable run will be about 300 feet. Projector is not permanently installed; i would terminate the cable run at/ near the ceiling or up stage lighting batten then plug in and drop down from there. Rear of house is not a permanent booth either; likely terminate in a wall jack for easy plugining in during showtime. Recommended products? Brands? I see a lot on the market with a wide range of prces. Want to avoid one designed for the home market and stay professional. Thanks in advance.
