    The HDMI 2.1 standard is faster than HDMI 2.0, the current connection used by modern home entertainment devices. It nearly triples the bandwidth of HDMI 2.0, defining a maximum speed of 48Gbps, compared with 18GBps. For 4K TVs, that means an HDMI 2.1 connection can handle 4K video at up to 120 frames per second.

    HDMI Version 2.1:   This was launched on 28 November 2017 and added support for higher resolutions and refresh rates. It was a relatively major update as indicated by the move from 2.0 to 2.1 in terms of the revision number.

    The main features added within HDMI version 2.1 included:

    • Support added for resolution of 10k at 120 Hz.
    • Capability added for specifying HDR metadata on a scene-by-scene or even a frame-by-frame basis.
    • Display Stream Compression (DSC) 1.2 is used for video formats higher than 8K with 4:2:0 chroma subsampling.
    • Introduction of a new HDMI cable category called 48G to enable cables to be certified to carry the new higher data rates.


    Asus are to launch world’s first HDMI 2.1 4K/144Hz gaming monitor next month. (May 2021)

    Back at CES 2021, ASUS unveiled a bunch of new gaming monitors for 2021. One of the more impressive showings was the Strix XG43UQ, the world’s first HDMI 2.1 gaming monitor. Availability information wasn’t available at the time of announcement, but now, ASUS has confirmed that this monitor will begin shipping in May.

    As of May 2021, the ASUS ROG Strix XG43UQ will be available, packing a 43-inch 4K panel with a 144Hz refresh rate and 1ms response time (MPRT). It also boasts DisplayHDR 1000 certification, making it one of the highest-tier HDR gaming monitors available at the moment with peak brightness of 1000 nits.

    Aside from HDR and high refresh rate 4K gaming, this display also offers Display Stream Compression (DSC) technology, which enables all of these features to work at once by removing bandwidth limitations. It is also set to be the world’s first HDMI 2.1 monitor, which means next-gen consoles like the Xbox Series X/S and the PlayStation 5 can utilise this display for 4K/120Hz gaming with AMD FreeSync enabled for variable refresh rate.

    Other features include Low Motion Blur Sync, FreeSync Premium Pro, and Asus Aura Sync for RGB lighting effects. Unfortunately, we do not have pricing information yet, but we’ve asked Asus and will update this post when we hear back.
