DisplayLink
Definition
USB graphics technology using host compression and an adapter display chip.
Detailed explanation
DisplayLink is a USB graphics technology in which host software compresses display data and a chip in a dock or adapter produces monitor output. It does not require the USB-C port to expose native DisplayPort alternate mode. CPU load, USB bandwidth, compression, and device firmware distinguish it from a GPU’s native display connection. Windows sees a virtual display adapter in addition to the native GPU path, and the dock’s outputs are constrained by the chip generation and USB link. High-motion video, protected content, color workflows, and sleep transitions can behave differently because pixels traverse compression and USB transport.
