What is hdmi 2.0?

HDMI (High Definition Multimedia Interface) is a digital interface for transmitting audio and video signals between devices. It is commonly used in home theaters, computers, and gaming systems to connect devices such as TVs, monitors, and speakers to a source, such as a cable box, DVD player, or game console. HDMI 2.0 is the latest version of the HDMI standard and was released in 2013.

HDMI 2.0 is an improvement over the previous HDMI 1.4 standard and offers a number of new features and capabilities. One of the main differences between HDMI 2.0 and HDMI 1.4 is the increase in bandwidth. HDMI 2.0 supports a bandwidth of up to 18 Gbps, which is significantly higher than the 10.2 Gbps of HDMI 1.4. This increase in bandwidth allows HDMI 2.0 to support higher resolution video and more audio channels, as well as additional features such as 3D video and 4K resolution.

4K resolution, also known as Ultra High Definition (UHD), is a resolution of 3,840 x 2,160 pixels. This is four times the resolution of Full HD (1920 x 1080) and provides a much clearer and more detailed image. HDMI 2.0 is capable of transmitting 4K resolution at 60 frames per second, which is important for smooth and seamless video playback.

In addition to supporting higher resolutions, HDMI 2.0 also supports an increased number of audio channels. While HDMI 1.4 only supported up to 8 audio channels, HDMI 2.0 supports up to 32 audio channels. This allows for a much more immersive audio experience, particularly when using a surround sound system.

One of the other key features of HDMI 2.0 is its support for dynamic auto lip-sync. This feature helps to synchronize the audio and video so that they are in sync and there is no delay between the two. This is particularly useful when watching movies or playing games with fast action, as it helps to eliminate any audio lag.

HDMI 2.0 also introduces the ability to transmit data over the HDMI cable, known as HDMI Ethernet Channel (HEC). This allows devices connected through HDMI to share an internet connection, eliminating the need for an additional Ethernet cable.

In addition to these features, HDMI 2.0 is backwards compatible with previous versions of HDMI. This means that devices with HDMI 2.0 ports can be used with devices that have older HDMI ports, although they may not be able to take advantage of all of the features of HDMI 2.0.

Overall, HDMI 2.0 is a significant improvement over the previous HDMI 1.4 standard and offers a number of new features and capabilities. Its increased bandwidth allows for higher resolution video and more audio channels, as well as support for 3D video and dynamic auto lip-sync. Its ability to transmit data over the HDMI cable, known as HDMI Ethernet Channel, allows for devices to share an internet connection. While it is backwards compatible with older HDMI devices, it is important to ensure that all devices in a setup are compatible with HDMI 2.0 in order to take full advantage of its capabilities.
