Moving my TV from a wall to an area above a mantel over a gas fireplace. The mounting area will be brick faced so I am installing a power conduit and a signal conduit to appear behind the TV mount. All of my electronics (HDMI devices, Directv box, etc) will be located in a credenza which is about 20 ft or so across the room from my TV. Is there an extension cable or a longer one connect cable I can buy to complete this project? The One Connect box is labeled BN96-44183A and had four HDMI ports and one coaxial connector for antenna. There is no power connector on this box, just signal. The TV is a 2017/2018 model UN65MU8000F. I searched this community but could not find a definitive answer for my model. Thanks,
