Standard HDMI Cables

Passive copper HDMI for the majority of connections: a console to a television, a laptop to a monitor, a receiver to a projector across a room. No power, no electronics, no direction to observe. Plug either end into either device and it works.

Where passive copper stops working

Reliability at 4K 60Hz holds to roughly 25 feet, and past that it depends heavily on conductor gauge and on how tolerant the equipment at each end is. The failure mode is rarely a blank screen. It is intermittent sparkle, occasional dropouts when the content switches resolution, or HDR that refuses to engage, and it is easy to misattribute to the television. If your run is longer than 25 feet at 4K, or longer than about 15 feet at 8K, look at active optical instead.

Cables intended to pass through a wall cavity need a CL2 or CL3 jacket rating to satisfy the National Electrical Code, regardless of length.
