HDMI cables are the way we connect our multimedia systems with the television and it’s important to understand how to choose them. HDMI cables support 4k picture definition (for more information about the different video resolutions, please go to our article)
Sound-wise the capability of an HDMI cable is also quite impressive. It can support up to 8 channels of good quality audio (24-bit/192kHz). Additionally HDMI cables can transmit 3D signals.
HDMI cables came in different versions that were going to make each one deprecated. Following it’s the chronological list of versions:
- HDMI 1.0: they were transmitting both and audio (2 channels only) signals with 165 MHz bands and bitrate of 4.9 GBs (released year: 2002)
- HDMI 1.2: more audio channels were added (5.1) (released year: 2004)
- HDMI 1.2a: this version introduces the CEC (Consumer Electronics Control) (the released year was 2005)
- HDMI 1.3: Increased bandwidth to 340MHz and the maximum bitrate to 10.2 Gbps (plenty for 3D video). This new version also introduces the “Deep Color” standard that granted over one billion possible colors, much more than the previous versions (released 2006)
- HDMI 1.4: big news here was the addition of the Ethernet capability, even if there are no many components on the market that can use this capability. (released year: 2013)
- HDMI 2.0a: it’s time for the HDR era. This new standard of cable supports it (the release year was 2015).
- HDMI 2.1: last but not the least. With this version the bandwidth reaches 48Gb/s to support a range of higher video resolutions and refresh rates, including 4K/120 and 8K/60.
4k resolution: which cable to choose?
Starting version 2.0 on, all the HDMI cables can transmit 4k video signals. To be sure always purchase cables with the “high speed” denomination. If the distance is up to 3 meters there won’t be an issue in the transmission.
