HDMI has always been one of the most popular connectors for transmitting audio and video between devices. It seems like it would be a long time until something else completely replaces it. The HDMI Forum has announced a new specification for HDMI connectors. This new specification called HDMI 2.1 sounds extremely promising and will be available to all vendors who have already adopted HDMI 2.0. The great thing about it is that it’s also backwards compatible. So, what’s so good about HDMI 2.1?
The main highlight of HDMI 2.1 is going to be its support for higher video bandwidth, supporting speeds up to 48Gbps with a new backwards-compatible ultra-high speed HDMI cable. In addition to this, it supports higher refresh rates than HDMI 2.0. The refresh rates include 60Hz for 8K and 120Hz for 4K. This is amazing refresh rates considering how high the resolutions really are. That’s not all, it even supports Dynamic HDR and resolutions all the way up to 10K. However, this is all likelihood may be limited to commercial use.
This is going to be perfect for gamers as the gaming experience with higher refresh rates is always a treat to the eyes. This new HDMI specification will bring with it a new way of eliminating lag, enabling smoother transition of frames, leading to a smoother gaming experience. It does this by making use of Variable Refresh Rate (VRR). If this hasn’t impressed you yet, HDMI 2.1 allows for something known as Auto Latency Mode (ALLM). This will automatically set the ideal latency which would yield the best results.
If you’re a little confused on how much of an improvement HDM 2.1 is over the previous standard, then have a look at this chart.
