I don't have a separate screening room. Every time we watch film I have to put a cable across the room.
But not anymore! I have now installed a cable across the room hidden behind curtains, the TV and a sofa. I have one end under the screen and the other, which is 1.5m long at the end, on a hook under the table where the projectors are placed. Fasterer to hook up, and no more tripping on wires. Very happy :-) High WAF too (wife acceptancy factor).
