To find the proper length HDMI cable to fit your needs, make sure to consider the distance between your TV and your HD components. You should choose in-wall rated cable if you plan to run your connections through walls (for example, when the TV is mounted and you want a clean look). Look for cables that come with extra-tight connectors, which are important for keeping things secure when using products like a full-motion TV mount. More expensive cables are made of higher-quality materials and come with a higher data transfer speed rating measured in gigabits per second (Gbps). This allows more bandwidth for streaming 4K Ultra HD and HDR content and helps to ensure signal purity, which is especially important when running cable over longer distances.
