The HDMI 2.1 specification has been officially released
The HDMI 2.1 specification has been officially released
For gamers, the key upgrades here is support for 4K 120Hz with 4:4:4 sampling and up to 12-bit colour, which is an amazing feat when compared to HDMI 2.0. HDMI 2.0 offered 18Gbps of bandwidth while HDMI 2.1 offers 48Gbps of bandwidth, offering an over 2x improvement to deliver increased image quality and even lower latency operation.Â
 Â
HDMI 2.1 will be backwards compatible with all existing HDMI standards, though it utilises the full bandwidth and features offered by HDMI 2.1, users will need to use a new HDMI 2.1 ultra high speed HDMI cable.Â
One of the biggest changes to HDMI 2.1 is the ability to utilise higher resolutions without compressions, with the standard supporting 8K 60Hz with ease with full 4:4:4 sampling. HDMI 2.1 has also been designed to offer an Auto Low Latency Mode (ALLM) to provide users with the smoothest, lag-free experience.Â
  
 Â
Â
For gamers, one of the biggest upgrades here will be the addition of Variable refresh rates (VRR), which is designed to reduce or eliminate lag while also preventing stutter or tearing while playing games, offering the same features as AMD FreeSync. At this time it is unknown how similar this technology is to AMD FreeSync over HDMI.Â
Â
The HDMI 2.1 compliance test specification is set to be published in stages during Q1-Q3 2018, which means that we are unlikely to see any devices with support for HDMI 2.1 in the near future.Â
This new standard is also likely to make waves within the PC industry, as HDMI’s new standard will likely be adopted by both Nvidia and AMD, forcing Nvidia to support a variable refresh technology outside of their proprietary G-Sync solution. This change should also help to make variable refresh rate displays more widely available in the future.Â
More information on HDMI 2.1 is available to read on HDMI Forum’s press release here. HDMI official presentation slide deck is also available to view here.Â
