The HDMI 2.1 standard is only compatible with the new cable called Ultra High Speed HDMI. It is the one that allows supporting the new bandwidth. While HDMI 2.0 is limited to one resolution 4K y 60 frames per second u 8K a 30 fps, HDMI 2.1 supports without disheveled a resolution of 10K is 120 fps. Come on, we have cable for a while.
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.
From 1080p 60Hz support with the first generation, HDMI cables evolved to support 1440p, and 4K, and refresh rates like 144Hz, and 240Hz. The latest generation, HDMI 2.1, introduced the landmark 4K 120Hz support, which unlocked next-generation gaming from the latest Xbox and PlayStation consoles. For the purpose of our question today, though
DisplayPort 1.4A is an iteration of DisplayPort 1.4 released in April 2018. The main upgrade provided by 1.4A compared to 1.4 is improved support for DSC (Display Stream Compression).

It can’t offer the same bandwidth as more modern HDMI 2.1 and DisplayPort 2.0/2.1 cables, so it can’t handle the same kinds of high resolutions and refresh rates. It’s still capable, but not as capable, which makes it less desirable for connecting cutting-edge displays..
