6.1.2.2 Genlock
Genlock is an example case of output locking.
Genlock refers to the ability to synchronize the pixel scanning of a GPU's display(s) to
a synchronization signal that is generated outside the computer that the GPU is in. This
ensures that video output sources from multiple video output devices (such as
workstations, cameras, or video recorders) are combined or switched properly.
Without proper synchronization, switching between sources may cause the picture
to jump or be lost momentarily while the receiving device tries to lock to a new signal.
Genlock is commonly used in video post-production, nonlinear editing (NLE), and
broadcast environment. Its use ensures that a workstation's graphics output is locked
