HDMI 2.1 will be the newest version of HDMI and is expected to release later in 2018. This upgrade includes, among other features, the ability to output 4K 60Hz video at a resolution up to 8K x 3K (7680×4320) with HDR10 color space support on TVs that include an HDMI input port or built-in UHD/HDR processor capability for displays without such capabilities.
The “hdmi 2.1 bandwidth chart” is a new specification that has been released by the HDMI Licensing Administrator. The specification allows for higher resolutions and refresh rates, which means you can now label your HDMI displays as “HDMI 2.1”.

Users looking for a new monitor should double-check the data sheet to ensure that it supports 4K/120 Hz (RGB, 10-bit color), Variable Refresh Rate (VRR), and other critical capabilities offered by the newest and greatest version of the HDMI protocol, which offers a 48-gigabit-per-second bandwidth.
That’s because, after contacting HDMI.org, TFT Central learned that the standards for HDMI 2.1 certification are really a lot more lenient than one would think. A representative expressly informed the magazine that HDMI 2.0 devices may now be labeled as HDMI 2.1 since the earlier version “never longer existed.” The consequence is that a producer may get away with promoting a monitor as HDMI 2.1 certified even if it only has HDMI 2.0 capabilities.
HDMI.org told TFT Central the following:
HDMI 2.0 is no longer in use, and devices should not claim conformance with it since it is no longer referenced.
HDMI 2.0 functionalities are now a subset of 2.1 features.
All of HDMI 2.1’s additional capabilities and features are available as options (this includes FRL, the higher bandwidths, VRR, ALLM and everything else)
If a device claims to be compliant with 2.1, it must also declare the features it supports so that there is “no mistake” (hmmmm)
“The answer from HDMI.org was that although everything may – or rather should be branded as HDMI 2.1,” the author stated, “manufacturers must additionally specify the features supported to comply with their certification standards.” “As far as I can tell, this indicates that the HDMI 2.1 designation is basically worthless (for the record, HDMI.org protested to my stating that).”
One of Xiaomi’s new monitors, which mentioned 2x HDMI 2.1 connections among its connectivity choices, triggered TFT Central’s article. However, according to the tiny print, it only supports a maximum resolution of 1920 x 1080 at a maximum refresh rate of 240 Hz.

Frequently Asked Questions
Can you use a HDMI 2.1 cable on 2.0 port?
A: Technically, yes. This is a question most people are asking because they want to know if the HDMI 2.1 cable will work on their older 1.4 port in order for them to be able to watch 4K video and such but technically it should still work with that old HDMI 1.4 port as well provided it’s not being used by anything else at the moment
Is HDMI licensed?
A: No, HDMI is not licensed.
Does HDMI 2.1 work on any TV?
A: HDMI 2.1 is the latest version of the HDMI spec, which supports a number of features such as 4K content at 60 Hz and HDR 10+. However, not every TV brand that has announced support for this spec actually does.
