DisplayPort Overview12

DisplayPort Market Penetration DisplayPort adoption grew significantly in 2019DisplayPort and DisplayPort Alternate Mode over USB-C The common monitor interface for personal computers Commonly supported on the USB-C interfaces supporting USB 3 Mandated for USB4 and ThunderboltEmbedded DisplayPort (eDP) 95% penetration in notebook PCs, used in many high-end tablets and nowautomotive13

DISPLAYPORT 2.014

DisplayPort 2.0 Summary DisplayPort v2.0 was released in June 2019 Major features added: Increase in data bandwidth performance (almost 3X)DSC support mandatedMST (Multi-Stream Transport) is now standard protocolExpanded Tunneling capabilityPanel Replay, similar to PSR (Panel Self Refresh) used for eDP15

DisplayPort 2.0 enables up to 3Xincrease in video bandwidthperformance First standard to support 8K resolution(7680 x 4320) at 60 Hz refresh rate withfull-color 4:4:4 resolution, including with30 bits per pixel (bpp) for HDR-10support Beyond 8K resolutions achieved withmaximum link rate to up to20 Gbps/lane and more efficient 128b/132b channel coding16

DP 2.0 Mandates Support for Display SignalCompression (DSC) VESA released DSC 1.2a in January 2017. DSC is now the industry standard data compression across the displayinterface. DSC was purposely designed to offer low latency, low complexity codec forvisually lossless image compression to increase the amount of data carriedby a display interface data rate, saving power.Key features include Native 4:2:0 and 4:2:2 coding, Up to 16 bits per color, High Dynamic Range(HDR) DSC is mandated in DP 2.0 specification and is a powerful feature to allowdesigners to optimize BW, performance and power for Native DP, DP Alt19September27 – 28,Mode products andtunneled DPover USB4.

Optimization for Shared Interface Use Numerous specification enhancements to simplify the use ofDisplayPort as an ingredient in the following interface examples: The USB-C connector, using the DisplayPort Alt Mode (DP Alt Mode)VESA Mobility DisplayPort Standard (MyDP)VESA Embedded DisplayPort Standard (eDP)ThunderBolt 3.0Wireless interfacesSeptember 27 – 28,20

Compliance Testing21

VESA PlugTest Events Provide significant value to member companies, particularly as newcapabilities and products are deployed. Demonstrate and improve Traditional Interoperability Test Native DP and DP Alt Mode over USB Type-CTM products HBR3, DSC, FEC, DisplayHDR and other new capabilities Verify Test Equipment Correlation VESA hosted two successful PlugTests in 2019 (Taiwan and US) VESA plans to host at least two PlugTests in 2020 Taipei, Taiwan: Q1 2020 (Tentative)Burlingame, CA: Q3 2020 (Tentative)22

DP 8K Cable Specification and Certification Developed as part of DP 1.4a specification update DP8K Certified cables provide added assurance of smooth operation and fullcompliance at the higher link rates Dozens of DP 8K cables have been certified since launch of program23

DSC Compliance Testing VESA released DP 1.4a DSC CTS v1.0 in July 2019 Compliance testing of DSC began in October 2019 for sourcesand sinks that support this feature Updates and increased test coverage are included in DP 1.4aDSC CTS v1.1 that will release this month.24September 27 – 28,

USB4 DisplayPortConsiderations32

USB4 Overview USB4TM released in August 2019USB PD 3.0 and USB Type-CTM 2.0 released in August with USB4 supportadded DP Alt Mode (multi function) required for USB4 products33

USB4 Overview Runs over USB Type-C interconnectTunnels USB3, PCIe and DP protocolsSignaling rates of 10 or 20 Gbps (10 to 40Gbps aggregated b/w)Helps converge USB Type-C connector ecosystem to minimize enduser confusion34

USB4 DisplayPort Considerations The USB4 product types of interest for DisplayPort are USB4Host, USB4 Hub and USB4 Device USB4 Hosts and Hubs must support DP Protocol Tunneling, withsupport optional for USB4 Devices USB4 Host and Hubs must support DP Alt Mode on downstreamUSB Devicefacing portsUSB4USB4 Interfacewith tunneledUSB, DP and PCIe dataUSB rDisplayPortSinkPCIe DeviceUSB4RouterUSB4USB DevicePCIeControllerUSB4RouterDisplayPortSinkPCIe Device35

USB4 Host - DisplayPort Requirements USB4 Host DisplayPort requirements are fairly straight forward USB4 Host Must Support: USB4 Fabric Configuration: Minimum of 2 lanes at 10 Gbps (Gen 2 x 2) USB 3.2 Data Transport, USB 2.0 Native DisplayPort DisplayPort tunneling through USB4 DisplayPort Alt Mode on all of it’s DFPsUSB-C Connector(s)USB2USB4- with fallback to USB3- Support for DP Alt Mode36

USB4 Hub – DisplayPort Requirements A USB4 hub is required to support DisplayPort Alt Mode on all of its DFPs. To connect to DisplayPort Sink, a USB4 hub contains a DP OUT Adapter thatreceives Tunneled DisplayPort traffic from a USB4 Port and sends it to aDisplayPort Sink via DP OUT Protocol AdapterUSB-C ConnectorUSB2USB4USB-C Connector(s)USB2USB4- with fallback to USB3- Support for DP Alt Mode37

USB4 Device – w/DisplayPort Supported A USB4 peripheral device must support 20G USB4 operation (Gen2x2)and optionally 40G USB4 operation (Gen3x2) Testing the DP Sink Link Layer will offer new challenges for compliancetestingUSB-C ConnectorUSB2USB4These functions are optional and depend on device features38

Summary39

Summary Product shipments and certifications on DP 1.4 based products continue togrow DP 2.0 product development and certifications expected in 2020 DisplayPort over USB-C is a game changer for small form factor andportable products and is rapidly becoming the defacto standard for laptops,tablets and handheld devices Momentum continues to grow for DisplayHDR product certification Development and adoption of new technologies continues to drive increasesin VESA membership growth USB4 mandated DP Alt Mode support and PHY convergence will continue to40accelerate adoption of DisplayPort technology
