HDMI 2.1 vs HDMI 2.0 cables on max effective data rate is a similar wash, with HDMI 2.1 supporting up to 42.6 Gbps, whereas HDMI 2.0 manages just 14.4 Gbps. All that additional bandwidth opens up the HDMI standard to higher resolutions and refresh rates than it ever had before, making it much more competitive with DisplayPort 1.4 and 2.0/2.1. In fact, they are totally different stories. HDCP 1.4 and HDCP 2.2 are two generations of content protection management. In most cases, HDCP 1.4 is adopted to protect full HD content and HDCP 2.2 is an upgraded version to protect 4K UHD. If you wanna enjoy 4K content that is managed by HDCP 2.2, an HDCP 1.4 device may fail your attempt. HDMI and Ethernet are two data transmission cables that cannot be more different. HDMI transmits audio and video signals, while ethernet cables transmit regular data. However, there is HDMI with Ethernet, a cable combining both features for multimedia purposes. Read this blog to learn the difference between those cables. What is an HDMI Cable? HDMI, or High-Definition Multimedia Interface, is Introduced in December of 2002, HDMI 1.0 started off by supporting the ability to transfer a digital video signal (standard or high-definition) with a two-channel audio signal over a single cable, such as between an HDMI-equipped DVD player and TV or video projector. Since the 10.2Gbps bandwidth of Category 2 cables was good for 4K until 30Hz, the HDMI 2.0 specification introduced Premium High Speed (or Category 3) HDMI cables capable of pushing data transfer rates of 18Gbps. These Category 3 HDMI cables can achieve 4K at 60Hz, while allowing 1080p displays to run at 120Hz. DisplayPort 2.1 cables operating at the spec's max capability of 80Gbps, meanwhile, are specified to operate at full performance at distances "beyond" 3.3 feet (1 m), VESA announced today. Fusion 8K 6ft HDMI Cable. Another perfectly viable HDMI 2.1 option, the Fusion 8K cable is the one to buy if you want extra protection: this six-foot beast features heavy braiding and highly reinforced plugs, which is one reason it tends to fetch a higher price than a lot of the 2.1-compatible cables we tested. Just remember that if the HDMI cable you've connected is a lower version than what you need, the audio and video being transferred will have a lower maximum resolution and refresh rate. 2. What is the Difference Between HDMI 2.0 vs HDMI 2.1? HDMI 2.0 and 2.1 are both revisions of the HDMI cables. While HDMI 2.0 upped the bar to 4K at 60 Hz or 8K at 30 Hz, HDMI 1.4 only offered 4K resolution at 30 FPS. It goes even further with the newest HDMI 2.1 standard, which supports 4K resolution at 120 Hz and 8K resolution at 60 Hz. It’s impressive that HDMI 2.1 can support resolutions up to 10K. DisplayPort 1.4 and above uses the DSC technology to compress the information by a 4:2:2 YCgCo ratio, providing it with the capability to feature an 8K display at a 120 Hz refresh rate. But HDMI has included DSC only from version 2.1 at 4:2:0. This provides less color detail than the 4:2:2 compression. 2KlRU8O.
