The DisplayLink network graphics technology is composed of Virtual Graphics Card (VGC) software that is installed on a PC and a Hardware Rendering Engine (HRE) embedded or connected to a display device. The DisplayLink VGC software is based on a proprietary adaptive graphics technology. The VGC software runs on a Windows, macOS, or Linux host PC and takes information from the graphics adapter and compresses the changes to the display from the last update and sends it over any standard network including USB, Wireless USB, Ethernet, and Wi-Fi. After receiving the data, the HRE then transforms it back into pixels to be displayed on the monitor. While the basic network graphics technology can be used on a variety of network interfaces (Ethernet, and Wi-Fi), DisplayLink has to date only designed products around USB 2.0, USB 3.0, and Wireless USB connectivity.[17]


The DL-41xx series came out in 2013. It is a USB 3.0 to LVDS device, supporting DL3 compression and HDCP 2.0 encryption.[24] It is designed to be embedded into monitors to enable USB as a video input on displays. It is described as a low power device, which enables it to be powered from the USB bus without the need for an external power supply. Power and video data can be delivered over a single cable.[25]

The IC has been integrated into a number of portable USB displays from AOC, ASUS and Taeseok.[26]

The DL-5xxx series was the first USB 3.0 graphics chipset to support 4K UHD resolutions. The chipset was launched in 2014 at Interop.[27]

The DL-6xxx series was announced at CES 2016.[14] This chip supports dual 4Kp60 displays over a USB-C or USB Standard A connector.


A key feature of DisplayLink technology is video compression, allowing the use of USB 2.0 and USB 3.0
