With the introduction of HDMI 2.1 gaming consoles like PS5 and Xbox Series X, as well as a growing number of HDMI 2.1 AVRs, TVs and monitors, you can now upgrade your current setup to have the ultimate entertainment experience. While there’s little 8K content available at this time, you can still future-proof your home entertainment setup — and 8K HDMI 2.1 is the gateway to get there. Ultra-high-speed data transfer for lag-free gameplay, extreme audio, vibrant colors and crisp details are some of the more popular 8K HDMI 2.1 features that will let you fully engage in a stellar gaming experience.
Resolution & Data Transfer Speed
While the difference between 8K and 4K resolution is great when comparing the number of pixels in each, it's nearly invisible to the naked eye. What really makes all the difference is the speed provided by the major increase in the 8K cable’s bandwidth. 8K’s higher resolution and frame rate require more data than 4K, and since a cable’s bandwidth regulates how much data the cable can transfer, HDMI 2.1 opens the throttle.
Boasting speeds of up to 48Gbps, 8K cables deliver data at more than twice the speed of 4K cables, which transfer data up to 18.2Gbps. Think of the 8K cable as a six-lane highway and the 4K cable as a two-lane highway. The six-lane highway can not only accommodate more traffic, but, when the same amount of traffic is traveling down each of those two highways, the traffic can flow much faster using six lanes instead of two.
4K HDMI 2.0 cables deliver 4K at 60 frames per second (fps), while 8K HDMI 2.1 cables deliver 8K content at 60fps or 4K content at 120fps, since less data is required to transmit 4K content. The bottom line is that if you have 4K content, you’ll get twice the frames per second using an 8K cable. We’re talking real-time gameplay, low latency and lag-free gaming. This makes 8K the clear choice for setups compatible with HDMI 2.1.
Additional Benefits of
8K HDMI 2.1
As mentioned earlier, 8K HDMI 2.1 has many benefits over 4K HDMI 2.0. While I won’t highlight every feature HDMI 2.1 brings to the table, I will address several features that, in addition to its incredible bandwidth, make it well worth the investment over HDMI 2.0 cables.
- Enhanced Audio Return Channel (eARC)
HDMI 2.1’s eARC capability not only permits a direct connection to an ARC/eARC-compatible soundbar or audio system, but when connecting eARC-compatible equipment, it can unleash a superior audio performance, accommodating spatial capability supporting up to 100 audio channels. Talk about amazing home theater surround sound! Featuring more bandwidth than conventional ARC, eARC is designed to accommodate complex multichannel formats, like Dolby TrueHD, DTS:X, Dolby Atmos, Sonos Beam and more. - Dynamic HDR
While HDR (High Dynamic Range) provides better brightness, contrast, details and colors than SDR (Standard Dynamic Range), HDR is static, keeping the same HDR settings for each frame. The Dynamic HDR in HDMI 2.1 enhances that visual experience further by allowing better flow between frames and making automatic adjustments, so each frame looks its best. According to HDMI.org, HDMI 2.1 “ensures every moment of a video is displayed at its ideal values for depth, detail, brightness contrast and wider color gamuts — on a scene-by-scene or even a frame-by-frame basis.” - Variable Refresh Rate (VRR)
For gamers, detailed, fluid gameplay with reduced or zero lag, stutter and frame tearing creates the ultimate, immersive environment — and HDMI 2.1 definitely delivers with a Variable Refresh Rate (VRR) up to 120Hz. According to TechRadar.com, VRR “helps to keep games looking smooth by switching up the refresh rate on the fly to best suit how much is happening on screen.” We’re talking super-smooth visuals for real-time gameplay, making it perfect for competitive multiplayer action.

Before You Buy, Check the Specs
While we could assume that all HDMI 2.1 cables include all of the features mentioned here and more, that’s not the case. To ensure you’re getting the best of the best with all that HDMI 2.1 has to offer, check the cable’s specifications and look for the Ultra Certified Cable label on the packaging. This label includes a QR code to help you identify HDMI cables that have met rigorous testing standards established by the HDMI Forum. Simply scan the HDMI label’s QR code using the HDMI Cable Certification app, available for both iOS and Android devices.
