What are USB Graphics Adapters?

USB graphics adapters let you connect additional monitors to a computer using a standard USB port — no dedicated GPU slot required. They use DisplayLink chip technology to compress and transmit display data over USB, with the encoding handled by a small software driver running on your CPU. This makes them ideal for adding screens beyond what your laptop's built-in video outputs (or dock) already support, whether that's a third monitor for spreadsheets, a fourth for reference material, or a dedicated display for video calls.
