`over a Standard USB-C Cable
`• Uses a standard “Full Feature” USB-C to USB-C cable which is designed to
`include DisplayPort
`• The above configuration uses two high-speed lanes each for DisplayPort
`and USB 3.1
`• Ideal for docking stations, or for displays or TVs that include USB 3.0 functions
`• DisplayPort performance provided by two lanes
`• DP v1.2 (existing Source devices): Two 1080p displays, or one 4k@30Hz
`• DP v1.4 (HBR3 Source devices): 4K@60, or HDR 4K@60 using 4:2:0 and 12bpp
`• 4 Lanes of DisplayPort available if only USB 2.0 implemented in Sink
`• Support for 4K@60, or two 2560x1600, or four 1080p

`DisplayPort Alternate Mode Compliance Test Plan
`
`• VESA is developing the DP Alternate Mode compliance test in
`coordination with the USB-IF
`• Compliance test specification (CTS) is under under general membership
`review
`• Draft 1.0 expected to release next quarter
`• The objective is to enable compliance testing for USB Type-C, and the DP
`Alt Mode for USB Type-C, at the same ATCs enabling the use of a single
`test station
`• Certification of many DisplayPort Alternate Mode enabled products is in
`progress at GRL and Allion ATCs

`• USB PD Compliance Testing
`• Demonstration of proper functionality/behavior for DP Alt Modes
`• A device must pass DisplayPort Alt Mode USB-PD certification tests to receive DP
`certification
`• Electrical testing of all supported modes with PHY test fixtures
`• USB PHY electricals
`• USB 3.1 Gen1 5G
`• USB 3.1 Gen2 10G (if supported)
`• USB 2.0 480Mb/s

`
`Compliance Test Issues
`Common compliance testing problems encountered
`• DP Alt Mode PHY Compliance
`• OS specific toolset are often required to properly get into test modes
`• Some products/chipsets do not support Test Automated over Aux
`• This is being addressed in new methodology under developer, the Link
`Training Test Automation Mode.
`• USB-PD testing issues
`• Specification has been changing
`• New tests added to draft CTS have uncovered implementation issues
`• DP Alt Mode CTS USB-PD Test 10.1.2 Status update Command Test failures.
`The test fails if the Status field is invalid
`• A number of other issues have been identified at recent USB-IOP events and
`VESA PlugTest events. Tests will be added to verify product compliance.

`
`Compliance Test Issues
`• 1 or 2 lane configuration compatibility issues
`
`• Source and sink chipset issues uncovered during interoperability testing of
`DP Alt Mode products using USB-C docks.
`• Issue occurs when Dock is configured in 2 lane mode to support 2 lanes of DP and 2
`lanes for USB 3.1
`• Sources fail if they don’t implement fallback rules in DP 1.4 specification
`• Sinks fail if they don’t support reduced lane operation or if they don’t
`correctly report CR and/or Link EQ/Alignment failures on unconnected
`lanes
`• Billboard implementations: many products have not updated to Billboard
`latest requirements
`• Compliance tests are under development to address these issues
