Generally, a high-speed HDMI 2.0 cable will work for a version 1.4 port. HDMI cables only transmit the data and high-speed cables can transmit the required data with higher bandwidth than regular HDMI cables. But any HDMI cable will work with any port and all HDMI cables support 4k with 60Hz. The type of HDMI cable will only really matter if
HDMI 2.0 supports a maximum bandwidth of 18 Gbps, which is enough to handle 4K resolution at up to 60Hz, or 1080p at up to 240Hz. In comparison, DisplayPort 1.4 has a maximum bandwidth of 32.4Gbps, which opens up a much greater resolution and frame rate potential. It supports 4K resolution at up to 120Hz without compression, and 8K resolution
Mini HDMI, or Type C, is also more compact than the standard connector but larger than Micro – 10,42 x 2,42 mm. Basically, it’s only about HDMI sizes. Like the previous type, it supports all common video and audio resolutions in addition to HD and Ultra HD (4K) formats. Mini is in greater demand but not as much as type A.
At the numbers level, HDMI 2.1 supports 48 Gbps bandwidth. To put this into perspective, HDMI 2.0’s support only extended to 18Gbps bandwidth. That’s a major difference and one that’s significantly greater than any difference that came before. For example, before HDMI 2.0 came through there was HDMI 1.4, and its bandwidth was limited to
Although a distinctly different technology, HDCP is sometimes confused with HDMI, since HDCP generations include HDCP 1.4 and 2.2, while recent HDMI generations include 1.4, 2.0, and 2.1. They are also often labeled alongside each other on source and display devices. As close as they are, though, these are two very different technologies.
HDMI 2.0 vs HDMI 2.1 Compared. HDMI 2.1 effectively handles 4K resolutions much better than the 2.0 standard as the bandwidth availability has been nearly tripled from 18 Gbps to 48 Gbps.. As both HDMI 2.0 and 2.1a handle 4K, now the 2.1a will be 4K @ 120 Hz smoother and more efficiently than ever before.
