Premier Manufacturer
A DisplayPort cable (DP for short) is an audio and video interface standard developed by the Video Electronics Standards Association. Developed to replace older video interfaces such as DVI and VGA, DisplayPort is primarily used in desktop computers, laptops, and home theatres. Still, generic DisplayPort cables typically available may not meet your application’s specific requirements, so custom DisplayPort cables can play a role in such situations.
As a leading manufacturer based in China, we specialise in providing custom DisplayPort cable solutions tailored to your needs. For example, we can adjust the data or video transmission rate using male-to-male DP cables and select the switch type (HDMI/Type-C) at the female end connections.

DisplayPort interface form
The DisplayPort interface can support not only full HD display resolution (1920×1080) but also 4K resolution (3840×2160) and the latest 8K resolution (7680×4320). It has a high-speed transmission rate and is reliable and stable.
The signals transmitted by the DisplayPort interface consist of the data channel signals that transmit the image and the auxiliary channel signals that transmit image-related status and control information, specifically the DisplayPort data transmission main channel (Main Link), auxiliary channel (AUX Channel), and connection (Link Training).
Overview of the Display Interface
Main Link: The main link is a unidirectional, high-bandwidth, low-latency channel used to transmit synchronous data streams such as uncompressed video and audio.

Auxiliary Channel (AUX CH): The auxiliary channel is a half-duplex, bidirectional channel used for link management and device control.

Advantages of DisplayPort
- The AUX channel in the DisplayPort connection enables bidirectional operation between terminal devices (such as Easync) and PCs (such as graphics cards), achieving plug-and-play.
- Supports G-SynciNvidia) and FreeSync (AMD) technologies, allowing the graphics card to communicate directly with the display without complex operations.
- DisplayPort connects the display to the computer digitally, supporting high transmission rates up to 240 Hz.
- DisplayPort requires fewer cables than analogue connections because only one cable transmits power and audio/video data.
- DisplayPort can connect multiple monitors. Other DisplayPort Channels can also be used for hardware such as cameras, touch screens, microphones, and USB connections.
- DisplayPort supports higher resolutions and refresh rates than VGA, DVI, or HDMI.
- DisplayPort transmits video and audio signals with more resolutions than any other connection type.
- DisplayPort transfers data faster than other standard interfaces, so you can send large files faster.
- With the latest version of DisplayPort, the transfer rate is up to 77.37 per second, supporting 8K video with 12-bit colour depth in every colour channel without any changes.
