Does HDMI video high-definition cable support EDID and DDC2B? Does this mean it has "plug and play" properties?
Publish Time: 2024-04-10
HDMI video high-definition cables usually support EDID (Extended Display Identification Data) and DDC2B (Display Data Channel version 2B) protocols. These two protocols are standards for transmitting display and display capability information between HDMI devices. EDID is used to transmit the basic information of the display, such as resolution, refresh rate, color space, etc., while DDC2B is used for communication and data exchange between HDMI devices.
Support for EDID and DDC2B means that when you connect HDMI devices, they can automatically exchange display and display capability information, allowing for "plug and play" functionality. This means you don't need to manually configure the devices, they automatically recognize and adapt to the connected monitor to provide the best possible display.
Therefore, the support of EDID and DDC2B by HDMI video high-definition cable can make the device more intelligent and convenient to connect and use, improving the user experience.
When the device supports EDID and DDC2B protocols, connecting HDMI video high-definition cable can bring more convenience and advantages:
Automatic resolution matching: After connecting an HDMI device, the device will automatically read the resolution information of the monitor, and then adjust the output resolution to match the best display effect of the monitor. This can avoid blurry or deformed images caused by resolution mismatch.
Automatic color space adjustment: EDID and DDC2B protocols can also transmit color space information supported by the monitor, such as RGB, YUV, etc. The device can automatically adjust the output color space based on this information to ensure the accuracy and vividness of the screen color.
Quickly identify external devices: When you connect a new external device, an HDMI cable that supports EDID and DDC2B can quickly identify the model and display capabilities of the external device, thereby automatically making adaptation settings without manual adjustments.
Provide a better user experience: The "plug and play" feature makes device connection easier and faster. Users do not need to worry about device compatibility or configuration issues and can focus more on the user experience.
Generally speaking, HDMI video high-definition cables that support EDID and DDC2B protocols can provide a smarter, more convenient, and better connection and display experience, allowing users to enjoy better audio-visual effects.
