Today marks a significant milestone in display interface technology as two major advances were announced at the conference Consumer Electronics Show (CES) in Las Vegas. the HDMI Forum It introduced HDMI 2.2, providing improved performance and greater bandwidth for high-resolution, data-intensive applications. At the same time, Video Electronics Standards Association (VESA) Announced updates to the DisplayPort 2.1 specification, upgrading to DisplayPort 2.1b, with notable improvements to cable length and flexibility.
HDMI 2.2 is a major upgrade over its predecessor, HDMI 2.1. Although it retains the same connector design, the standout feature is the increased bandwidth to 96 Gbps, thanks to the new “Ultra96” HDMI cables. This expanded bandwidth supports higher resolutions and refresh rates, including 4K at up to 480Hz, 8K at up to 240Hz, and even 10K at up to 120Hz.
Although no current monitors or displays meet these maximum specifications, the additional bandwidth of HDMI 2.2 will primarily benefit demanding, data-intensive applications. These technologies include AR/VR/MR, spatial reality, light field displays, and commercial uses such as large-scale digital signage, medical imaging, and machine vision.
In addition to supporting higher resolutions, HDMI 2.2 handles for a long time My voice-Optical synchronization issues through Introducing Latency Signal Protocol (LIP). This protocol improves the alignment of audio and video signals, especially in complex setups that involve multiple devices such as AV receivers or amplifiers. The result is the elimination of frustrating audio and video lag, ensuring a smoother entertainment experience – a particularly attractive feature for home theater enthusiasts.
To ensure the authenticity and quality of Ultra96 cables, the HDMI Forum has implemented an extensive certification program, including anti-counterfeiting measures. This initiative addresses potential issues related to tariffs and counterfeit products, ensuring that consumers receive authentic, high-performance cables.
HDMI 2.2 is supposed to be released in the first half of the year, although devices supporting the new standard are unlikely to hit the market in significant numbers until next year. It is worth noting that the standard is backward compatible, which means it will work seamlessly with devices that have HDMI 2.1 or older ports.
The updates to the DisplayPort 2.1 specification are still noteworthy, although they’re not as groundbreaking as HDMI 2.2. VESA has announced new DP80LL (“low loss”) active cables that support up to four-lane UHBR20 link rates, achieving a maximum throughput of 80 Gbps over lengths up to three metres. This improvement triples the cable length for UHBR20 connections compared to existing DP80 passive cables, providing greater flexibility in device placement and setup configurations.
These updates are made possible through VESA’s collaboration with industry leaders like Nvidia, ensuring optimal performance and compatibility between GPUs and upcoming DisplayPort 2.1b technologies. Certified DP80LL cables should hit the market in the coming months.
While advances in HDMI 2.2 and DisplayPort 2.1b highlight the industry’s dedication to delivering high-quality visual experiences, most consumers won’t feel an immediate impact. The current HDMI 2.1 and DisplayPort 2.0 standards are more than adequate to power everyday devices, and it may be years before these new standards become mainstream.
However, these innovations paved the way for the next generation of display technology, paving the way for immersive visuals, seamless synchronization of audio and video, and enhanced flexibility in professional and consumer applications. As these technologies mature, they promise to redefine how we experience and interact with visual media.
