In this article, we will be talking about VESA Certified DP 2.1 80Gb Cables. In the realm of cutting-edge display technologies and gaming setups, the demand for high-bandwidth, reliable connectivity has never been greater.
With the advent of DisplayPort (DP) 2.1, expectations were set high for unparalleled display resolutions, refresh rates, and color depths. However, amidst the excitement, a notable discrepancy has emerged, particularly concerning the advertised capabilities of 2-meter VESA Certified DP 2.1 cables capable of 80Gbps.
This article delves into the heart of the matter, shedding light on the reality behind these claims and offering guidance for consumers navigating this confusing landscape.

The DisplayPort 2.1 standard, heralded by the Video Electronics Standards Association (VESA), promised significant advancements over its predecessors. With a theoretical maximum bandwidth of 80 Gbps, DP 2.1 set the stage for next-generation displays to flourish, supporting resolutions far beyond 4K, refresh rates up to 240Hz, and more vibrant colors through deep color formats.

This technological leap was a boon for professional users requiring meticulous detail and color accuracy and gamers seeking the ultimate immersive experience.
The controversy lies in the advertised performance of 2-meter cables. Vendors on platforms and marketplaces have been quick to tout their cables as VESA Certified DP 2.1, capable of achieving the maximum 80Gbps bandwidth.
However, examining VESA’s certification page closer reveals a starkly different reality. According to VESA’s official certifications, only cables up to 1 meter, and sometimes 0.8 meters, have been certified to handle the total 80Gbps bandwidth. The best certification for a 2-meter cable falls significantly short, capping at 40Gbps.
This discrepancy is not just a matter of numbers but has tangible effects on user experience. For setups requiring the total bandwidth of DP 2.1—such as running a Samsung 57″ double UHD monitor at 240Hz—the limitations of these 2-meter cables become painfully evident. Users have reported flickering images, indicating that the cable is not transmitting data at the required rate.
The marketing of these cables has led to considerable confusion among consumers. Many, relying on the claims made by sellers, have found themselves with products that fall short of their needs and expectations.
This situation is exacerbated by the fact that specific high-end monitors, which could greatly benefit from the enhanced capabilities of DP 2.1, are often bundled with cables inadequate for exploiting the monitor’s full potential.
The root of the problem lies in the physical limitations of copper cables over longer distances. Achieving 80Gbps over copper is a formidable challenge, significantly as cable lengths increase.
Signal degradation, electromagnetic interference, and other factors contribute to the diminishing performance of these cables. As noted by industry experts, achieving such high bandwidths over lengths greater than 1 meter without resorting to active technologies like fiber optics is currently beyond the reach of available technology.
Though not yet widespread, the solution may come in the form of active fiber optic cables. These cables, designed to carry signals over longer distances without significant loss, represent the next step in the evolution of connectivity. However, their adoption has been slow due to higher costs and less availability than their copper counterparts.
Awareness and due diligence are critical for consumers navigating this landscape. It’s essential to critically evaluate vendor claims, seek out VESA’s official certification for cable performance, and consider the actual needs of your setup. For those requiring a total 80Gbps bandwidth over distances greater than 1 meter, exploring active cable solutions, despite their higher cost, might be the only viable option at this juncture.
The actual VESA Certified DP 2.1 80Gb cables are designed to meet the highest standards set by the Video Electronics Standards Association (VESA) for DisplayPort technology, promising unparalleled bandwidth capabilities up to 80Gbps. Here are our recommendations below:

The issue of 2-meter VESA Certified DP 2.1 cables not living up to the 80Gbps claim is a poignant reminder of the gap that can exist between marketing claims and technical reality.
As the industry continues to evolve and technology advances, it is incumbent upon manufacturers, standards bodies, and consumers alike to foster an environment of transparency and education.
Only through this collective effort can we ensure that the promise of next-generation display technologies is fully realized without leaving consumers in the lurch.
