Before we dive into the compatibility of HDMI 1.4 cables with HDMI 2.0 ports, let’s take a step back and look at the different versions of HDMI. The HDMI specification has undergone several revisions since its introduction in 2002. Each revision has introduced new features, increased bandwidth, and improved performance.
The key differences between HDMI versions are:
- HDMI 1.0: Released in 2002, this was the first version of HDMI and supported up to 1080i resolution.
- HDMI 1.3: Released in 2006, this version increased the bandwidth to 340 MHz and added support for 1080p resolution.
- HDMI 1.4: Released in 2009, this version increased the bandwidth to 640 MHz and added support for 3D resolution and Ethernet connectivity.
- HDMI 2.0: Released in 2013, this version increased the bandwidth to 1.8 GHz and added support for 4K resolution at 60 Hz.
Cable Categories
HDMI cables are also categorized based on their performance. There are two main categories:
- Standard HDMI cables: These cables are designed to support up to 1080i resolution and are suitable for older devices.
- High-Speed HDMI cables: These cables are designed to support up to 1080p resolution and are suitable for devices that require higher bandwidth.
In 2009, the HDMI Licensing Administrator introduced a new category called HDMI with Ethernet. These cables not only support higher bandwidth but also have an Ethernet channel that allows devices to connect to the internet.
Cable Bandwidth vs. Port Bandwidth
When it comes to HDMI cables, the bandwidth of the cable is not the same as the bandwidth of the port. The bandwidth of the cable refers to the maximum amount of data that the cable can transmit per second, while the bandwidth of the port refers to the maximum amount of data that the port can receive and process per second.
In general, the bandwidth of the cable should match or exceed the bandwidth of the port. For example, if a device has an HDMI 2.0 port with a bandwidth of 1.8 GHz, it’s recommended to use a high-speed HDMI cable with a bandwidth of at least 1.8 GHz.
Compatibility of HDMI 1.4 Cables with HDMI 2.0 Ports
