If you’re new to PCVR, it can be confusing to understand why some headsets use DisplayPort cables, why others use USB-C, and how wireless streaming works. Each type of connection affects the clarity of the picture, the smoothness of movement, and even how comfortable your headset feels. This guide breaks everything down in an easy way and also explains how Pimax Dream Air uses a new type of DisplayPort cable to make things lighter and more comfortable.
Why DisplayPort Remains the Benchmark
DisplayPort is widely regarded as the most capable interface for high-end PCVR, thanks to its ability to deliver high bandwidth with exceptionally stable timing. This is especially important for next-generation VR headsets that rely on ultra-high-resolution panels and high refresh rates. With the help of DSC, DisplayPort 1.4a can comfortably deliver the extremely high bandwidth required to drive the Pimax Crystal Super at its native resolution in 90 Hz mode, achieving full-quality transmission without resorting to heavy compression. Beyond raw throughput, DisplayPort also offers excellent flexibility for VR-specific display modes, dual-panel architectures, and custom timing.
DisplayPort is widely regarded as the most capable interface for high-end PCVR, primarily because of its ability to deliver high bandwidth with extremely stable timing. With support for DSC, DisplayPort 1.4a can handle the ultra-high-resolution panels seen in next-generation VR headsets while maintaining 90–120 Hz refresh rates without relying on heavy compression. Beyond raw throughput, DisplayPort is also highly flexible for VR-specific display modes, dual-panel configurations, and custom timing.

HDMI, while excellent for living room displays, was never designed with VR’s unique timing requirements in mind. Even with HDMI 2.1, developers face greater latency constraints and less freedom in configuring high-refresh custom modes.
-
USB-C’s DisplayPort Alt Mode is promising, but real-world support varies widely. Many laptops, for example, output only two DP lanes through their USB-C ports, and the way USB-C multiplexes power, data, and video can introduce instability or bandwidth limitations.
-
Mini DisplayPort performs similarly to full-size DP but is steadily disappearing from modern GPUs.
What About Wireless VR or USB Streaming?
-
Wireless performance might fluctuate depending on interference, router placement, and network congestion. They must also decode the incoming video stream during wireless streaming, which increases heat and power consumption and can shorten battery life.
-
Wired USB-C streaming is more stable but still constrained by the available protocol bandwidth. Even USB4 and Thunderbolt rarely match the stability and low-level timing fidelity of an uncompromised DisplayPort link.
For these reasons, streaming is excellent for convenience and casual PCVR, but it still cannot match DP’s reliability and visual clarity for high-end simulation, racing, and immersive gaming.
Rethinking the DisplayPort Cable: The Dream Air Approach
One of the most common complaints about traditional DisplayPort VR cables is their bulk and weight. High-bandwidth cables require thick shielding and robust connectors, which often place extra strain on the user and restrict movement. With Dream Air, we set out to solve this long-standing issue without sacrificing the uncompromised image quality that DisplayPort provides. Unlike traditional DP cable systems, it introduces a re-engineered cable architecture that significantly improves comfort and ergonomics.
-
Significantly reduced cable weight for lower wearing pressure
-
More balanced load distribution, reducing strain on the user
-
Greater flexibility, enabling more natural movement with fewer restrictions
-
Full preservation of DP 1.4a bandwidth and signal integrity
