Link-Training Tunable PHY Repeaters (LTTPRs) which help maintain signal integrity for high-speed DisplayPort signal transmission from source to sink. The most recent DisplayPort standard is 2.0, which was released in 2019. However, the most common standard is DisplayPort 1.4a, which can be found in many computer monitors these days. When using only two lanes on the USB-C connector via DP Alt Mode to allow for simultaneous SuperSpeed USB data and video, DP 2.1 can enable such configurations as: The scheme will certify UHBR cables under DP40 and DP80 tiers as explained below: DP40 Cables – UHBR10 link rate (10 Gbps x4 lanes = 40 Gbps) DisplayPort 2.0: Supports resolutions up to 16K, or two 4K monitors at 144Hz with no compression. It also supports 3D sync technology, G-Sync, and FreeSync.
With the updates to DP 2.1 made on 17 Oct 2022 VESA have also updated the DisplayPort cable specification to provide greater robustness and enhancements to full-size and Mini DisplayPort cable configurations that enable improved connectivity and longer cable lengths (beyond two meters for DP40 cables and beyond one meter for DP80 cables) without diminishing UHBR performance. What if your cable isn’t good enough and isn’t DP40 or DP80 certified? Improved user experience with augmented/virtual reality (AR/VR) displays, including support for 4K-and-beyond VR resolutions. While the best HDMI 2.1 cables have a higher bandwidth than DisplayPort 1.4 (the most common standard), DisplayPort is still preferred by gamers thanks to the much better support for VRR and also the capabilities for multi-display connectivity. HBR3(High Bit Rate 3): 8.10Gbit/s bandwidth per lane (810MHz link symbol rate), introduced in DP1.3, also used for DP 1.4Why it made the cut: The UGREEN 8k is multi-layered to protect the wires inside and look nice while doing it. JSAUX 1.2 DP Cable is an affordable and highly-durable DisplayPort cable that offers decent performance (it supports 60Hz 4K and 165Hz 2K video) and a solid overall value for the price, which ultimately makes it one of the better offerings on the market.

All in all, if you want the best DisplayPort cable for the money, this one is pretty much it. Pros:DisplayPort cable market is full of products that look the same and offer the same level of performance. For that reason, it is pretty hard to distinguish the good from bad products. Nevertheless, quality always finds its way to the customers, and we present to you BENFEI DisplayPort to DisplayPort cord, a cable that offers solid performance, compatibility with 4K (60Hz) and full HD video materials, as well as support for both 5.1 and 7.1 audio. VESA also tell us that “there are other, more subtle updates (e.g., data structure clarification/addition, metadata definition extension) with each new standard version that improve the interoperability as well as the visual quality even at lower than the maximum link rate. That is why there is an obvious merit for a product to be certified to the latest version of DisplayPort standard, irrespective of its maximum link rate.” VESA also announced that qualified VESA DisplayPort Authorized Test Centers (ATCs) are ready to begin testing and certification of UHBR end-products using approved test equipment and reference sink and source devices for interoperability testing. This means the test centres are good to go as manufacturers begin to product source devices, and displays with the new connection type. If you seek a high-quality DP cable that offers great durability and versatility, Snowkids DisplayPort Cable is the thing for you. To be more exact, this cable supports 32Gbps data transfer speed, as well as HDR and HBR3. This cable comes in four lengths (1m, 2m, 3m and 5m), it is available in gray, red and blue color, and more importantly, offers solid compatibility.
DisplayPort 2.1 on the other hand uses 128b/132b encoding; each group of 132 transmitted bits represents 128 bits of data. This scheme has a much higher efficiency of 96.96%. In addition, forward error correction (FEC) consumes a small amount of the link bandwidth, resulting in an overall efficiency of ~96.7%. This means that the transferrable data rate can be much closer to the bandwidth capacity of the connection. So for DP 2.1 you get up to 77.37 Gbps data rate out of 80Gbps total bandwidth (=96.7%). An updated version of our earlier table is included below to show the efficiency rate: Transmission mode One of the worst things, when you are connecting your devices, is discovering that one of your cables is too short for the configuration that you need. In that sort of situation, your only option is to improvise, and that is something that usually doesn’t end up well. While each standard has its own advantages, it all comes down to which version of each cable you are using. Newer versions of HDMI and DisplayPort support higher resolutions and more features. HDMI Versions Just to be clear, DisplayPort cables are not classified by version, they are classified by the amount of bandwidth they can handle. Our main issue with the new standard is the rather odd certification approach that means that officially a device doesn’t even need to support the new UHBR to pass as DP 2.1 and earn that badge! When the high bandwidths and new speeds are the absolute number 1 thing being promoted by VESA, and being talked about by every media outlet covering DP 2.1, this should be a baseline requirement. Everyone is going to expect a DP 2.1 device to feature new speeds beyond DP 1.4 at the absolute least. In our opinion, if a device doesn’t support UHBR it shouldn’t be calling itself DP 2.1.
Two 4Kx4K (4096×4096) displays (for AR/VR headsets) @120Hz and 30 bpp (10-bit) 4:4:4 HDR (with DSC) Why it made the cut: This cable from Capshi was made with gamers in mind, and they seem to like it! Whether you use DisplayPort or HDMI, remember that using a certain version of the cable will not automatically upgrade existing devices with older specifications. For example, even if you have an HDMI 2.1 cable, you can’t watch 8K video if your TV only supports the older HDMI 1.4 ports. So, you should make sure that all your equipment supports the cable standard you’ve chosen. Cable Matters 4K DisplayPort to DisplayPort Cable, Computer Monitor Cable 6 ft, 4K@60Hz, 2K@144Hz,...

Maybe this won’t be too much of a problem, and maybe manufacturers will kindly list the UHBR speed for any device they promote as DP 2.1. But it does add a layer of complexity and confusion to the new scheme that we think is unnecessary. In our opinion, UHBR should be a baseline requirement. We don’t really mind if that is only the lowest UHBR10, or the higher UHBR13.5 or UHBR20, but one of these new speeds should be required for it to be considered DP 2.1 in our opinion and that speed should be whatever is required to support the resolution and refresh rate promoted without needing any compression measures (excluding DSC) that would impact the visual experience. Achieving greater alignment between DisplayPort and USB on a common PHY has been a particularly important effort within VESA given the significant overlap in use case models between the DisplayPort and USB4 ecosystems,” stated Alan Kobayashi, VESA Board Chair and VESA DisplayPort Task Group Chair. “DisplayPort 2.1 brings DisplayPort into convergence with USB4 PHY specifications to ensure the highest video performance across a broad range of consumer products...”
The DisplayPort 2.1 UHBR certification programme was launched in February 2022. Through the DisplayPort UHBR Certification Program, device and cable manufacturers can send new products to DisplayPort authorized test centers (ATCs) for testing and certification
