Some experts suggest that the HDMI 2.1 cable can not work with HDMI 2.0 ports, but they are wrong.
Almost all standard ports in digital networking are backwards compatible, like a USB 3.0 drive will work on a USB 2.0 port (the problem would be some incompatibility between the devices).
In the same way, 2.1 will also work with the 2.0 port.
Will HDMI 2.1 Work W0ith 2.0 Port
The new HDMI 2.1 bring many new features, including the following:
- Ability to transmit higher resolution video at 120Hz or 240Hz.
- Up to 32 audio channels for immersive surround sound.
- Dynamic synchronization of video and audio streams.
HDMI 2.1 of the HDMI Specification is backwards compatible with earlier versions and is available to all HDMI 2.0.
HDMI, or High Definition Multimedia Interface, is a digital interface that transmits uncompressed video data and compressed/uncompressed digital audio data from one device to another.
HDMI cables are most often used in home theatre setups, but they are also found in TVs, Blu-ray players, computers, A/V receivers, video game consoles, cable boxes and so on.
This interface has three versions:
- HDMI 1.4
- HDMI 2.0
- HDMI 2.1
HDMI 1.4 Port
The HD-1.4 HDMI version was launched in May of 2009 and enabled several additional features that made the connector far more versatile.
For example, it provided the HDMI Ethernet Channel for sharing an internet connection.
Perhaps even better was the additional support for 4K resolutions at 30Hz. HD-1.4 also added an audio return channel.
HDMI 2.0 Port
An HDMI 2.0 port is the standard in ports for monitors, televisions, and other devices that connect to a TV or computer monitor.
It provides an uncompressed video signal that supports High Dynamic Range (HDR) content for TVs and Monitors With HDR capability.
There are two types of HDMI cables:
- HDMI 1.4a
- HDMI 2
The HDMI 2.0 Port also provides less data loss and better interactivity with other devices linked to the TV or monitor through this port.
HDMI 2.1 Port
HDMI 2.1 is the new version of HDMI that supports higher resolutions, better bandwidth, and enhanced audio support.
It can support up to 10K resolution, which is four times the resolution of 4K.
HDMI 2.1 also has better bandwidth so that users can enjoy more immersive sound on their monitors.
For example, it can support up to 32 PCM sampled stereo audio channels while previous versions only supported 7.2 channels max.
Are HDMI 2.0 And 2.1 The Same Size?
HDMI 2.0 and HDMI 2.1 both use the same cable, but they have different video resolutions and frame rates supported by each standard version.
HDMI 2.0 can carry resolutions up to 10K and frame rates up to 120 frames per second with 18 gigabits per second bandwidth, whereas HDMI 2.1 has 48 Gbps.
Do you need HDMI 2.1 for 4K?
The newest release in the high-definition multimedia interface (HDMI) standard, HDMI 2.1, is designed to drive the next generation of television and entertainment displays with resolutions up to 8K.
For most people, it is noticeable compared to the HDMI 1.4 and 2.0; however, you do not need this cable to support 4K.
Can you use HDMI 2.1 in a 1.4 port?
Some people wonder if they can use HDMI 2.1 in a 1.4 port. Yes, they do. The HDMI connector has not changed in any way – except for size (they’re different dimensions).
They both fit into each compatible cable size, but it would be better to use the latest version of HDMI if possible.
HDMI 2.1 is backwards compatible with HDMI 2.0, which doesn’t mean that your old cable won’t work, but it does mean that you likely won’t see the benefits of this new technology unless you upgrade to one of the latest ports on your TV or another device.
HDMI 2.1 cables are backwards compatible with HDMI 2.0, but older versions of HDMI will not provide access to all the improvements and upgrades of HDMI 2.
