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. a b c Craig Wiley (25 April 2013). "How to Choose a DisplayPort Cable, and Not Get a Bad One!". DisplayPort.org. Archived from the original on 5 July 2013. The FURUI Nylon presents us with a superb DisplayPort cable that is capable of producing an 8K resolution quality even at 120Hz. For the high-end monitors of the future, it can even go up to a whopping 16K. It can be hard to believe how high the quality of the FURUI’s resolution capacity is, far surpassing the needs of most consumers, but you can rest assured … the FURUI comes VESA certified.
Not all DisplayPort cables are capable of functioning at the highest levels of bandwidth. Cables may be submitted to VESA for an optional certification at various bandwidth levels. VESA offers four levels of cable certification: Standard, DP8K, DP40, and DP80. [41] :§4.1 These certify DisplayPort cables for proper operation at the following speeds: Sag, Anshel (12 February 2019). "Display Technologies Ruled At CES 2019". Forbes.com .

In December 2010, several computer vendors and display makers including Intel, AMD, Dell, Lenovo, Samsung and LG announced they would begin phasing out FPD-Link, VGA, and DVI-I over the next few years, replacing them with DisplayPort and HDMI. [63] [64] [65] This is a very high-speed Mini DisplayPort cable, great for connecting laptops to high-resolution high band HDMI 2.0 has an Audio Return Channel (ARC), which means you only need a single HDMI cable to send audio from a TV to your soundbar or AV receiver. HDMI 2.1 also has an Enhanced Audio Return Channel (eARC), which allows you to send uncompressed, high-quality audio from your TV to your soundbar or AV receiver. DisplayPort has historically had higher bandwidth than the HDMI standard available at the same time. The only exception is from HDMI 2.1 (2017) having higher transmission bandwidth @48 Gbit/s than DisplayPort 1.3 (2014) @32.4 Gbit/s. DisplayPort 2.0 (2019) retook transmission bandwidth superiority @80.0 Gbit/s.

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. Standards". Vesa .

Products incorporating DisplayPort 2.0 are not projected by VESA to appear on the market until later in 2021. [27] [28] The transmission mode used by the DisplayPort main link is negotiated by the source and sink device when a connection is made, through a process called Link Training. This process determines the maximum possible speed of the connection. If the quality of the DisplayPort cable is insufficient to reliably handle HBR2 speeds for example, the DisplayPort devices will detect this and switch down to a lower mode to maintain a stable connection. [8] :§2.1.1 The link can be re-negotiated at any time if a loss of synchronization is detected.

In April 2013, VESA published an article stating that the DisplayPort cable certification did not have distinct tiers for HBR and HBR2 bandwidth, and that any certified standard DisplayPort cable—including those certified under DisplayPort 1.1—would be able to handle the 21.6 Gbit/s bandwidth of HBR2 that was introduced with the DisplayPort 1.2 standard. [42] The DisplayPort 1.2 standard defines only a single specification for High Bit Rate cable assemblies, which is used for both HBR and HBR2 speeds, although the DP cable certification process is governed by the DisplayPort PHY Compliance Test Standard (CTS) and not the DisplayPort standard itself. [37] :§5.7.1, §4.1 Both HDMI and DisplayPort have published specification for transmitting their signal over the USB-C connector. For more details, see USB-C §Alternate Mode partner specifications.
Another major improvement with DisplayPort 1.4 was on the audio front, where it moved from a maximum audio sample rate of 768kHz to 1,536kHz. It also increased the maximum number of audio channels from 8 to 32. Should you buy DisplayPort 1.4? HDMI Specification 1.3a" (PDF). HDMI Licensing, LLC. 10 November 2006.
