With full HDR & HDCP compatibility this product is fully future-proof and ready for the new and demanding HDMI 2.0 audio and video signals on the market. HDMI 2.1 also added several new features to further improve the revision update, including built-in variable refresh rate (VRR), Auto Low Latency Mode, Display Stream Compression 1.2a, and more. The HDMI 2.0 Matrix Switch is perfectly suited to handle enormous bandwidth requirements and create spectacular information & presentation applications. But, TMDS is still supported on HDMI 2.1 as a backward compatibility feature. This technology is different from the older TMDS (Transition Minimised Differential Signalling) used on older HDMI interfaces, which cannot support anything close to the HDMI 2.1 requirements. The HDMI Forum has announced the release of HDMI 2.0 at IFA 2013, which ups the specifications bandwidth to 18 Gbps (from 10.2 Gbps in HDMI 1.4) and adds a range of new features designed for. According to, that was a necessity achieve higher uncompressed resolutions beyond 4k 60Hz, and it allowed HDMI 2.1 to reach the required 48Gbps of bandwidth to deliver those higher resolutions.

The higher resolution support was achievable thanks to HDMI 2.1's use of Fixed Rate Link signaling. This allows HDMI 2.1 to push resolutions of up to 10k and support high refresh rate 120Hz displays at 4k resolutions without the need for display stream compression (DSC), a lossy algorithm to reduce bandwidth requirements. But HDMI 2.0 cables only can handle 18 Gbps, so if you want content in 4K 120 (or, eventually, 8K), you’ll not only need components with sufficient bandwidth but cables with that same capacity too.

The biggest selling point to HDMI 2.1 was its bandwidth upgrade from 18Gbps on HDMI 2.0b to a whopping 48Gbps with HDMI 2.1. When HDMI 2.1 was released a few years ago, it included a new cable standard supporting 48 Gbps bandwidth. HDMI discussion just became a lot more difficult.īefore this news dropped, HDMI 2.1 was originally a full-on upgrade over HDMI 2.0b in terms of resolution and raw bandwidth, with some extra features tacked on.

As we’ve discussed before, it’s all a matter of bandwidth and the right settings. However, HDMI 2.0 also does have the ability to execute 4K 120Hz. We don't know the official reasoning behind this major name change, but it seems like it will foster confusion and create problems for consumers going forward. The biggest thing with HDMI 2.1 is the exponential growth in bandwidth compared to HDMI 2.0, which has been most associated with 4K 60Hz. According to a report from TFT Central, HDMI 2.0 is being dropped as an official name altogether and will be replaced by HDMI 2.1. If you thought the naming scheme for USB ports was confusing, get ready to see the same thing happen to HDMI.
