What is cea 861?

CEA-861 is a standard developed by the Consumer Electronics Association (CEA) for video timings and formats used in digital displays. It specifies the resolutions, refresh rates, pixel formats, and other parameters for digital video signals. CEA-861 is used in HDMI and DisplayPort interfaces for connecting digital devices such as computers, Blu-ray players, and game consoles to digital displays such as televisions and computer monitors. The standard has evolved over time to support new video formats and technologies, including 3D, 4K, and HDR (High Dynamic Range) video. Compliance with CEA-861 ensures interoperability between digital devices and displays and enables the delivery of high-quality video content.
