The Video Electronics Standards Association (VESA) has announced that DP8K Certified DisplayPort cables—native DisplayPort cables that are guaranteed to support DisplayPort High Bit Rate 3 (HBR3)—are now available in the marketplace.
HBR3 is the highest bit rate (8.1Gbps per lane) supported by DisplayPort standard version 1.4 and provides the speed required to drive 8K video resolution at 60 FPS using a single cable, as well as multiple UHD displays. Key applications supported by HBR3 include high-performance gaming, AR/VR and television broadcasting.
VESA is also currently engaged with its members in the development of the next DisplayPort standard generation, with plans to at least double the data rate enabled by DisplayPort. VESA plans to publish this update within the next 18 months. Further developments in display interfaces are needed to address future performance requirements of traditional displays, such as resolutions beyond 8K, as well as greater enhancement of the user experience with AR/VR displays, including VR in UHD. Syed Athar Hussain, VESA vice chairman and AMD Senior Display Domain Fellow, said:
“As display resolution, refresh rate and color space continue to grow, we see strong adoption of HBR3 on displays, discrete graphics card and mobile PC platforms. HBR3 certified cables facilitate a seamless connectivity experience to end users. DisplayPort HBR3 has enabled support for 8K and novel wide-aspect resolutions, such as 3840×1080, at refresh rates of 144Hz and beyond for HDR gaming”.
James Choate, compliance program manager for VESA, also commented:
“Since we first launched our HBR3 Certification Program nearly a year ago, more than 20 DisplayPort devices have undergone HBR3 certification, including sources, sinks, docks, and now, cables. With DP8K Certified DisplayPort cables, a single-port solution for 8K displays is finally attainable. DP8K Certified cables provide added assurance of smooth operation and full compliance at the higher HBR3 link rate”.
With DP8K Certified cables, devices with native DisplayPort connectors can reliably support 5K or 8K monitors, as well as high-performance UHD monitors. For USB-C to USB-C connections, this same level of performance is available with “SuperSpeed USB 10 Gbps” cables, which support the HBR3 data rate for DisplayPort Alt Mode.
Cable vendors offering DP8K Certified DisplayPort cables include Elka International, Hotron Precision Electronic Industrial, Dezhou HongJu Communication Technology, Ji-Haw Industrial, and Ningbo Prime Electronic. HBR3 cable testing is now available at DisplayPort Authorized Test Centres (ATCs), including Allion Labs and Granite River Labs. A complete list of DisplayPort ATCs can be found here.
