HDMI cables are known as a technological marvel because of their myriad benefits. These cables help to transfer data from a playback source to a display device. These cables enhance the overall quality of the data being transferred and hence it is possible to view your favourite movie in high-definition.
When purchasing HDMI cables, you will come across four basic types. These include HDMI 1.1, HDMI 1.2, HDMI 1.2a and HDMI 1.3. You might not notice major differences in the functionality or even the style of the cables. However, these upgrades were carried out for testing purposes. Mentioned below are some of the basic differences.
The earliest and the most basic form of HDMI cables, the 1.1 supported DVD only. Transmitting high definition images was not possible with HDMI cable 1.1.
The first upgrade for HDMI 1.1 included support for One Bit Audio Format. Super Audios and DSD (Direct Stream Digital) were also supported in HDMI 1.2. Apart from these features, HDMI 1.2 also included availability of the widely used HDMI Type ‘A’ connector for PC sources and displays with full support for PC video formats. The option to support the YCbCr colour space was also added in 1.2. The enhancements in these cables made it possible for later displays to support future low voltage sources, such as the PCI Express I/O technology.
Version 1.2a did not see many upgrades or enhancements as previously thought. It offered support for HDMI CTS 1.2a technical consistency. 1.2a also consists of an additional cable and connector that aids in connector testing and Authorised Testing Centre (ATC).
HDMI 1.3 increases the single link bandwidth to 340 MHz (10.2 GBPS) with added support for high end display devices. HDMI 1.3 also boasts of support for 10-bit, 12-bit and 16-bit. “x.v.Color™” and IEC 61966-2-4 xvYCC colour standards are also supported.
These are just few of the features that separate the four versions of HDMI cables. Refer to these features before you opt for a type of HDMI cable.
