Offered as an alternate mode of USB Type-C, the new VirtualLink specification is intended to simplify the setup process and significantly reduce the setup time of VR headsets – avoiding key obstacles to VR adoption. It replaces multiple cables and connectors with a single lightweight cable that can deliver the power, display, and data required to power VR headsets through a single USB Type-C connector.
In addition, says the consortium, it also brings immersive VR experiences to smaller devices with fewer ports, such as thin and light notebooks. VirtualLink supports four high-speed HBR3 DisplayPort lanes scalable for future needs, a USB3.1 data channel for high-resolution headset cameras and sensors, and up to 27 watts of power delivery.
Purpose-built for VR, VirtualLink optimizes for the latency and bandwidth demands that will enable headset and PC makers to deliver the next generation of VR experiences, the consortium says. The consortium also announced the publication of an advance overview of the VirtualLink specification, available to companies that wish to receive details ahead of the upcoming VirtualLink 1.0 specification.
“Simulating reality requires incredible visual fidelity and processing power,” says Jason Paul, general manager of gaming and VR, Nvidia. “With a single, high-bandwidth cable, VirtualLink unlocks the full potential of the PC to power amazing VR experiences.”
