The bilateral symmetry of the Type C plug has already put smiles on many faces, not having to flip the USB connector three times to find the right plug orientation will be a nice treat and steal some thunder from Apple's Lightning. That is not all that USB 3.1 will be bringing however, 10Gbps of data throughput and up to 100W on a single cable have also been announced as part of the new standards capabilities. There is something new today as well, support for DisplayPort over USB 3.1 which will perhaps only be available over specialized cables but could become a standard feature.
DisplayPort Alternate Mode takes advantage of the nature of USB 3.1 which offers four lanes for traffic to pass through, with a choice of USB data at up to 10Gbps per lane, up to 100W of power, DisplayPort AV at up to 8.1Gbps or at DP 1.2a speeds of 5.4Gbps which is likely the top speed on the first cables released. For those initial cables you will need all four available lanes to be able to display at 4k resolutions but once the speed is increased to 1.3's 8.1Gbps you should be able to see VESA's promise of 4k video, Superspeed USB data and up to 100 Watts of power over a single cable. Even when all four lanes are devoted to DisplayPort to run 5k video the cable will still support USB 2.0 speeds thanks yo separate pins dedicated for that function.
"The new Type C USB connector is causing a lot of excitement, thanks in part to its reversibility (you can plug it in either way up) and high rates of data and power transfer. But there's now another reason to buy into in: DisplayPort support."

It is official, DisplayPort 1.3 has finished VESA approval and should be hitting the streets in the near future. Freesync support came with 1.2a which is why it was not mentioned, however DockPort has been enhanced with the higher 8.1 Gbps link rate for each of the four lanes present which means you can support a 4k monitor using two of those lanes, leaving the other two available for USB, audio or even power.
This also means that 4k and even 5k monitors can function over a single DisplayPort 1.3 cable without any compression and with the use of VESA's Coordinated Video Timing you can have a pair of 4k monitors function in multi-monitor mode ... assuming you have the graphical horsepower to run 7680 x 2160. It is rather impressive to see this jump to 32.4 Gbps combined link rate that can deliver 25.92 Gbps of uncompressed video data.
Newark, CA (15 September 2014) The Video Electronics Standards Association (VESA) announced the release of the DisplayPort 1.3 audio / video (A/V) standard. An update to the widely used DisplayPort 1.2a standard, this latest version increases the maximum link bandwidth to 32.4 Gbps, with each of four lanes running at a link rate of 8.1 Gbps/lane a 50% increase from the previous version of the DisplayPort standard. Allowing for transport overhead, DisplayPort's 32.4 Gbps combined link rate delivers 25.92 Gbps of uncompressed video data.
The increased bandwidth enables higher resolution monitors, including recently announced 5K monitors (with pixel resolutions of 5120 x 2880) using a single DisplayPort cable without the use of compression. It will also enable higher resolutions when driving multiple monitors through a single connection using DisplayPort's Multi-Stream feature, such as the use of two 4K UHD monitors, each with a pixel resolution of 3840 x 2160, when using VESA Coordinated Video Timing.
DisplayPort 1.3 continues to support video conversion to VGA, DVI and HDMI. DisplayPort 1.3 adds support for HDCP 2.2 and HDMI 2.0 with CEC (Consumer Electronics Control), which enhances DisplayPort's utility for television applications, including 4K video with copy protection. The new standard adds support for the 4:2:0 pixel structure, a video format commonly used on consumer digital television interfaces, which enables support for future 8K x 4K displays.
DisplayPort 1.3 also enhances DisplayPort's value for multi-function interfaces that combine data transport, A/V transport and other capabilities on a single cable. It further refines protocols that enable DisplayPort to share a single cable with other data types. With its higher 8.1 Gbps per-lane link rate, DisplayPort 1.3 can support a single UHD monitor with 60Hz refresh and 24-bit color over two lanes, while assigning the remaining two lanes to increase capacity for alternate data types, such as SuperSpeed USB data, as allowed in DockPort. DisplayPort is the A/V transport standard used by DockPort, Thunderbolt and other wired and wireless multi-function interface standards.
While becoming a mainstream video standard, DisplayPort continues to be at the cutting edge of A/V transport, said VESA Board of Directors Chair Alan Kobayashi, Fellow & Executive R&D Management for DisplayPort Group at MegaChips Technology America. These new enhancements to DisplayPort will facilitate both higher resolution displays, as well as easier integration of DisplayPort into multi-protocol data transports, which will satisfy consumer's desire for simplicity and ease-of-use.
The DisplayPort standard is offered to VESA members without any license fee. For more information about DisplayPort, please visit http://www.displayport.org or connect with us on YouTube.

Dynamic refresh rates have two main purposes: save power by only forcing the monitor to refresh when a new frame is available, and increase animation smoothness by synchronizing to draw rates (rather than "catching the next bus" at 16.67ms, on the 16.67ms, for 60 Hz monitors). Mobile devices prefer the former, while PC gamers are interested in the latter.
Obviously, the video camera nullifies the effect.
NVIDIA was first to make this public with G-Sync. AMD responded with FreeSync, starting with a proposal that was later ratified by VESA as DisplayPort Adaptive-Sync. AMD, then, took up "Project FreeSync" as an AMD "hardware/software solution" to make use of DisplayPort Adaptive-Sync in a way that benefits PC gamers.
Today's news is that AMD has just released an FAQ which explains the standard much more thoroughly than they have in the past. For instance, it clarifies the distinction between DisplayPort Adaptive-Sync and Project FreeSync. Prior to the FAQ, I thought that FreeSync became DisplayPort Adaptive-Sync, and that was that. Now, it is sounding a bit more proprietary, just built upon an open, VESA standard.
If interested, check out the FAQ at AMD's website.

Remember DockPort? The three in one connection we have discussed in the past? The Thunderbolt-ish connection for devices with DisplayPort which allows transmission of audio and video plus USB data and power all on one connector. It's here! (even if the devices aren't quite common yet)
NEWARK, CA (3 June 2014) The Video Electronics Standards Association (VESA) today announced the release of the DockPort standard. Developed by several VESA member companies, DockPort is an optional extension of the DisplayPort standard that will allow USB 3.1 data and DC power for battery charging to be carried over a single DisplayPort connector and cable that also carries high-resolution audio/video (A/V) data.
This new extension of the DisplayPort standard is fully backward compatible with all existing DisplayPort devices. When a DockPort-enabled DisplayPort source such as a computer or tablet is connected with a DockPort-enabled DisplayPort sink such as a display monitor or docking station A/V plus USB data and power will be transferred over a common cable through a single connector. If either the source or sink device is not a DockPort-enabled, then source and sink will recognize only the DisplayPort A/V data stream.
As computing platforms become increasingly mobile, it becomes necessary to reduce the number of external connectors, explained Steve Belt, Corporate Vice President - Strategic Alliances & Solutions Enablement AMD, a VESA member company. With DockPort, VESA has developed a technology standard that enhances elegant docking designs, reduces mobile form factors, and enriches the user experience with streamlined, one-cable access to a wide range of external displays, peripherals and storage.
DockPort is the first royalty-free industry standard that combines these three essential interface functions into a single connector. VESA first revealed its intention to develop this standard at the 2014 International Consumer Electrics Show. It anticipates that several vendors will demonstrate DockPort-enabled DisplayPort systems at Computex Taiwan, which begins today.
Until today, most mobile computing platforms required three separate interfaces to support power charging, data transmission and external video, said Chris Griffith, Business Development Manager for Consumer and Computing Interface at Texas Instruments, a VESA member company. With DockPort, VESA has elegantly merged this ungainly tangle of wires into a single, sleek connector, combining power charging with the industrys most popular data transportUSBand the industrys highest-speed A/V transportDisplayPort. DockPort can reduce system implementation cost as designers can reduce external connectors and simplify docking implementations.
VESA is developing a compliance test protocol to certify systems that meet the DockPort standard. Systems that satisfy this test protocol will be permitted to display VESAs new DockPort logo on their packaging as a guide for consumers seeking this capability.
The new DockPort standard demonstrates the enormous adaptability of the DisplayPort standard, according to VESA Board Chair Alan Kobayashi, Fellow & Executive R&D Management for DisplayPort Group at MegaChips Technology America. On the one hand, DisplayPort is a flexible A/V transport protocol that easily coexists with other protocols, like USBit plays nicely with others. On the other hand, DisplayPort is also a robust and proven connector design whose electro-mechanical properties can accommodate data and power over a common passive copper cable and interface.

According to French website, hardware.fr, the VESA standards body has accepted AMD's proposal for FreeSync into an extension of the DisplayPort 1.2a standard. FreeSync is the standards-based answer to NVIDIA's G-Sync, a process for allowing the monitor to time itself according to its driving GPU. At CES 2014, AMD claimed that the technology was already in development to be used for mobile devices to save power (less frequent monitor refreshes).
By presenting image to the user only when the work is complete, you can avoid "tearing" and latency. The tearing will be eliminated because the graphics card does not change the image being drawn by the monitor as it is trying to display it. The latency is eliminated because it does not need to wait until the monitor is ready (up to one-over-the maximum refresh rate of the monitor). It should also save power by reducing its refresh rate on slower scenes, such as an idle desktop, but that is less of a concern when you are plugged into a wall.
What does this mean? Nothing yet, really, except that a gigantic standards body seems to approve.

One of AMD's pet projects will be seeing the light of day in the very near future, one that could put another nail in Thunderbolt's overpriced coffin. AMD in association with several other VESA members have developed an update to DisplayPort called DockPort that will provide USB 3.0 power and data over the cable at the same time it transmits up to 21.6 Gbps of DisplayPort Video. This will be of great usage when connecting your machine to a docking station, with one cable you get a lot of connectivity options and could also mean much smaller and less expensive docking stations are possible.
INTERNATIONAL CES, LAS VEGAS (7 January 2014) – The Video Electronics Standards Association (VESA®) announced today that DockPort will be added as an official extension to the existing DisplayPort standard. DockPort is an emerging technology that enables high-speed USB 3.0 data over the existing DisplayPort connector. Originally developed by AMD, Texas Instruments, and other VESA member companies, the DockPort extension will allow notebooks, tablets and other small form factor computers to aggregate the display, data and power interfaces into a single convenient connector.
Computers and other smart devices require high-speed I/O ports to share high-resolution video with external displays, high-bandwidth data with external storage and other peripherals, and power for battery charging. As notebooks and tablets become thinner and more portable, consumers want to combine these three common interfaces into a single port on their mobile device. With a single DisplayPort connection using the new DockPort extension and enhanced power capabilities under development, consumers will be able to attach their computers or tablets to a docking station and have instant, hassle-free access to a wide array of external resources.
“Consumers are happiest when they can personalize their electronics systems and reduce the number of cables they need to deal with at the same time,” explained Steve Belt, AMD’s corporate vice president of strategic alliances. “We identified DisplayPort as an ideal starting point and began collaborating with other industry leaders to create DockPort as an extension of DisplayPort’s capabilities. With just one inexpensive connector, users can now access power, a mouse, keyboard, external optical and hard disk drives, printers, gaming controller, and up to four external monitors. That’s a lot of capability from a single, standardized connector.”
AMD’s Discovery Tablet reference design, which utilizes DisplayPort with the DockPort extension to enable video, data and power over one connector, won two 2014 CES Innovation Awards.
“VESA’s decision to augment the popular DisplayPort standard with the single-connector capabilities of TI’s innovative DockPort controller is a win for end equipment designers and consumers,” said Wes Ray, systems and applications manager for Consumer and Computing Interface at Texas Instruments. “As an open standard, DockPort will be readily available for designers to implement, and more quickly deliver, the convenience of a single connection in devices such as tablets, notebooks, docking stations and dongles.”
DisplayPort is the world’s most advanced, high data rate video interface standard. It connects computers and other video sources to televisions and displays, while maintaining backward compatibility with VGA, DVI and HDMI. The global standard is backed by more than 200 technology leaders worldwide.
Designed to be robustly ‘future proof’ as well as backward compatible, DisplayPort allows a video source to drive up to four displays, and it is the only video interface that can support 4K UHD TVs and displays with deep color at 60 frames per second. DisplayPort with the DockPort extension will continue to be a royalty-free standard. DisplayPort-certified systems are available from every leading display manufacturer, and consumers purchase millions of DisplayPort products every year.
“Being a modern, high-speed, packet-based digital interface, DisplayPort was designed to be extensible while also providing backward compatibility,” said Craig Wiley, Sr. Director of Marketing for Parade Technologies, and Chair of the VESA Board of Directors. “Similar to Thunderbolt and MyDP, the new DockPort extension will utilize the flexibility of DisplayPort technology to create a single display, data, and, in the near future, power connector, while still being backward compatible with all other DisplayPort devices. We expect the DockPort feature will appear in main-stream products since its performance is tailored for standard connectors and passive cables.”
