On top of mandatory requirements, DP 2.1 has introduced optional features that manufacturers may or may not choose to take advantage of, such as VESA’s Panel Replay capability, which improves power efficiency by reducing power consumption when the display is displaying a static image most of the time. 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?

You’ve all heard of DisplayPort before, a common video interface featured on nearly all graphics cards and monitors nowadays. DisplayPort (herein shortened to “DP” in many places) is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). It is primarily used to connect a video source to a display device such as a computer monitor and as well as video, it can carry audio, USB, and other forms of data. The DisplayPort has the capability to provide a scalable digital display interface with optional audio and high-definition content protection (HDCP) capability for broad usage within business, enterprise, and consumer applications. The interface is designed to support both internal and external digital display connections. Examples of external applications for DisplayPort include display connections between PCs, monitors, and projectors. 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… So if you’re looking for a DisplayPort to HDMI converter to make use of an HDMI display, you’ll need to be aware that HDMI has these limits, even if they’re unlikely to be met in most cases. DisplayPort is certainly more future-facing. What Should You Look For In A HDMI To DisplayPort connector?VESA make the point that there is no need for manufacturers to have a higher price point because of the additional silicon needed to support UHBR, if the device simply does not need that. That’s true, but we believe that DP 2.1 is so clearly positioned as offering new UHBR speeds everywhere you look, making this optional could (and will) lead to confusion. In our opinion, UHBR should be a requirement, and manufacturers should have to list the UHBR speed alongside the DP 2.1 branding. Other DisplayPort 2.1 Features

A: Yes, the DP Hub supports the use of a Mini-DisplayPort adapter or conversion cable to transmit signal to the DP Hub. Keep in mind that the source Mini-DisplayPort must meet the DisplayPort 1.2a specification.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. If you’re looking to grab yourself a converter cable or connector, then there are a few things you will want to look out for. This article will take you through the latest generation of DP that you will soon start to hear more about, and that is now, as of 17 October 2022, DisplayPort 2.1. We will refer to this as “DP 2.1” throughout now that this updated version has been announced. The initial DP 2.0 standard for which this article was originally written was published in June 2019, although actual consumer DP 2.0 devices in the monitor and display space have yet to appear. DP 2.1 supersedes the 2.0 generation. The standard “defines the new normative requirement and informative guideline for component and system design” as VESA put it. The new DisplayPort capabilities included in DisplayPort 2.0 / 2.1 have begun the cycle of hardware development that will result in such technology becoming available to consumers in a range of products over the next few years. More discussion on timescales later on.

This is how (mainly) TVs are able to access HD sound and visuals and is done through the use of just one simple HDMI cable. What Is DisplayPort? 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. DP 2.1 still uses the same physical connection as older generations, but you will need a cable that can support the new UHBR if you have an actual UHBR device, and want to use DP 2.1 properly. VESA also have a separate certification scheme for compatible cables which has a fairly simple structure thankfully, and this time there is an associated logo scheme which should in theory make it easy to select an appropriate cable. Why is it so much simpler for cables than for devices?!

Features

This new interface is designed to work along side of the proprietary digital visual interface (DVI) used between the personal computer and an external display, as well as the legacy low-voltage differential signaling (LVDS) interface used inside laptops, monitors, and TVs to connect to LCD panels. As DisplayPort becomes more readily available, eventually it replaces VGA, DVI, and LVDS as the display interface standard. Desktops & All-in-Ones, Electronics & Accessories, Projectors & Accessories, TVs & Home Theater, Laptops Last Published Date DisplayPort offers excellent flexibility to power multiple devices via a single port. With the MST hub, you can deal with multiple displays. Due to the small form factor, you can use it at the office or home. You can connect a maximum of 4 HDMI monitors or TVs. Also, you can make a video wall that creates a hub perfect for trade shows, schools, retail outlets, conference rooms, etc.
