DISABLING A DISPLAY REFRESH PROCESS

摘要

A method performed by a physical computing system, the method includes disabling a display refresh process of a video controller (202) of the physical computing system if no active display device is connected to the physical computing system. A physical computing system includes a video controller (202) comprising a rendering engine (204) and a display refresh controller (206); a memory controller (212) connected to a memory (214); and a display controller (310) to determine whether an active display device is connected to the physical computing system; in which a display refresh process performed by the display refresh controller (206) is disabled when no active display device is connected to the physical computing system.
