Virtual-Display-Driver is a kernel-level driver for Windows that emulates physical monitors and audio devices. It serves as a virtual monitor emulator, headless server display emulator, and virtual audio device driver to enable extended desktop space and sound routing on systems without physical hardware connections.
The project enables the simulation of monitors with custom resolutions, refresh rates, and identification profiles, including support for High Dynamic Range output. It also provides software-defined audio interfaces to simulate virtual microphones and speakers.
The software covers broad capability areas including headless server operation, remote desktop stream enhancement, and virtual audio routing. Additionally, it includes utilities for overlay screen capture and picture-in-picture streaming of specific windows or screens.
