Standard available to all VESA members [ dubious – discuss] with an extensible standard to help broad adoption [67] AMD is delighted to collaborate with Samsung and VESA to demonstrate the next generation of high-resolution, high-refresh, high-fidelity visual experiences enabled by DisplayPort 2.1 products across gaming, productivity, and professional segments,” said Syed Athar Hussain, VESA board vice-chairman and AMD CVP and display domain senior fellow. “Pairing our VESA DisplayPort 2.1-certified AMD Radeon RX 7900 Series graphics cards with Samsung’s Odyssey Neo G9 showcases a premium ultra-smooth, low-latency, high-refresh gaming experience at 8K2K DUHD 240Hz with UHBR13.5. We are excited for users to experience these upcoming products for themselves, and they can be confident that source, sink, and cable interoperability will be assured by the VESA UHBR Certification Program.” DisplayPort version 1.2a was released in January 2013 [15] and may optionally include VESA's Adaptive Sync. [16] AMD's FreeSync uses the DisplayPort Adaptive-Sync feature for operation. FreeSync was first demonstrated at CES 2014 on a Toshiba Satellite laptop by making use of the Panel-Self-Refresh (PSR) feature from the Embedded DisplayPort standard, [17] and after a proposal from AMD, VESA later adapted the Panel-Self-Refresh feature for use in standalone displays and added it as an optional feature of the main DisplayPort standard under the name "Adaptive-Sync" in version 1.2a. [18] As it is an optional feature, support for Adaptive-Sync is not required for a display to be DisplayPort 1.2a-compliant.

The total bandwidth of the main link in a standard 4-lane connection is the aggregate of all lanes: A newer 1.3 and 1.4 version, that both have a maximum data rate of 25.92 Gbits/sec, are both becoming more widely available. With the increased bandwidth capabilities, it opens up the floodgates to higher resolutions such as 7,680 x 4,320 (8K). The DisplayPort main link is used for transmission of video and audio. The main link consists of a number of unidirectional serial data channels which operate concurrently, called lanes. A standard DisplayPort connection has 4 lanes, though some applications of DisplayPort implement more, such as the Thunderbolt 3 interface which implements up to 8 lanes of DisplayPort. [39] :4 Thankfully unlike the mess that the HDMI forum created with HDMI 2.1 where everything could end up being certified as “HDMI 2.1”, VESA will still be certifying devices under the older DisplayPort 1.4, and even DP 1.2, schemes where applicable or required. Not everything is going to be certified as DP 2.1, which would have left consumers to try and figure out which features are really included. If a device only has DP 1.2 or DP 1.4 capabilities, and perhaps only needs those capabilities to support it, then those schemes will continue to be available and certified against. This is definitely good news we think, as it means that when you see DP 2.1 listed, you know it should include that specific newer connection, and will support at least some of the features and capabilities associated with this new generation. However, as you read on, you will see it’s unfortunately not as simple as it perhaps should be… High-resolution displays and multiple displays with a single connection, via a hub or daisy-chaining [68]Getting a DisplayPort cable shouldn’t be a headache. While there can be some nuance for some situations, you are unlikely to not find satisfaction with at least one cable from this list. DisplayPort cables themselves are relatively simple, with the devices they connect with usually being the source of any difficulties. Why trust us Reduced bandwidth transmission for 15-metre (49ft) cable, at least 1920 × 1080p @ 60 Hz at 24 bits per pixel HBR3 (High Bit Rate 3): 8.10 Gbit/s bandwidth per lane (810 MHz link symbol rate), introduced in DP 1.3 That sounds a bit confusing, so let’s use the Capshi cable’s stats to explain: 8K@60Hz, 4K@144Hz, 1080P@240Hz. At a refresh rate of 60Hz (60 frames per second), you can get an 8K resolution, while at a refresh rate of 240Hz you can only get 1080P.
VESA certified DP80 cables must support up to the UHBR20 link rate (20 Gbps) defined by DisplayPort 2.1, with four lanes, providing a maximum throughput of 80 Gbps. VESA certified DP80 cables will also support the UHBR13.5 link rate (13.5 Gbps), which is also defined by DisplayPort 2.1. a b c d e f g Although this format slightly exceeds the maximum data rate of this transmission mode with CVT-R2 timing, it is close enough to be achieved with non-standard timings
