I have a bit of a problem and was wondering if someone here could propose a solution. After rebuilding my basement post-flood, I decided to run a length of HDMI cable through my wall and around the room so that I could hide my cable box and XBOX One behind my bar, while connecting it to a TV hanging on the wall opposite the bar. The cable inside the wall is about 50 feet long. Here's my general setup: XBOX, connected via HDMI cable to a signal booster, booster plugged into an HDMI port on the wall, 50 foot cable in wall to HDMI going around the room to a port on other side, TV connected to said port. Without the signal booster, I had no sound or video, which is why I bought the booster in the first place. With it, the sound and video (most commonly sound) cut off at random intervals. Perhaps I need a different booster? Or maybe there's another solution. Thanks in advance for your help.
