On 22 September 2014, VESA published the DisplayPort Alternate Mode on USB Type-C Connector Standard, a specification on how to send DisplayPort signals over the newly released USB-C connector. One, two or all four of the differential pairs that USB uses for the SuperSpeed bus can be configured dynamically to be used for DisplayPort lanes.
Currently, DisplayPort is the most widely implemented alternate mode, and is used to provide video output on devices that do not have standard-size DisplayPort or HDMI ports, such as smartphones and laptops. All Chromebooks with a USB-C port are required to support DisplayPort alternate mode in Google's hardware requirements for manufacturers. [81]
In VirtualLink mode, there were six high-speed lanes active in the USB-C connector and cable: four lanes transmit four DisplayPort HBR 3 video streams from the PC to the headset while two lanes implement a bidirectional USB 3.1 Gen 2 channel between the PC and the headset. Unlike the classic DisplayPort USB-C alternate mode, VirtualLink has no ...
The USB4 specifications make no reference to a minimum feature set for its DP Alternative Mode functionality, but Thunderbolt 3 does. In practice, Intel's family of TB 3 controllers requires at least DisplayPort 1.2 at HBR2 speeds to support 4K60 output, but is also available with up to HBR3 speeds according to the DisplayPort 1.4a ...
USB4 supports DisplayPort 2.0 over its alternative mode. [105] [106] DisplayPort 2.0 can support higher than 8K resolution at 60 Hz losslessly due to new UHBR 10, 13.5, and 20 signaling standards (DSC 1.2 used in DisplayPort 1.4 for that resolution is not lossless) in 8 bit and 8K 60 Hz with 10 bit color and use up to 80 Gbit/s (effective ...
DisplayPort Alternate Mode 2.0: USB4 (requiring USB-C) requires that hubs support DisplayPort 2.0 over a USB-C Alternate Mode. DisplayPort 2.0 can support 8K resolution at 60 Hz with HDR10 color. [125] DisplayPort 2.0 can use up to 80 Gbit/s, which is double the amount available to USB data, because it sends all the data in one direction (to ...
As stated at CES in January 2023, HDMI Alternate Mode for USB Type-C is no longer being updated [200] as there are no known products using this protocol, reducing its relevance in the current market. This will reduce consumer confusion as DisplayPort Alternate Mode is the primary video protocol of choice over USB-C.
Windows Dev Kit 2023 came pre-loaded with Windows 11 Pro and features a Qualcomm Snapdragon 8cx Gen 3 system-on-a-chip (SoC), 32 GB LPDDR4X RAM, 512 GB NVMe SSD, Wi-Fi 6, Bluetooth 5.1, three USB-A, two USB-C (with DisplayPort Alternate Mode support), one Mini DisplayPort (with HBR2 support), and one physical Gigabit Ethernet port (embedded USB).
