Patent ID: 7705842

Claim:
At least one computer-readable storage medium having computer-executable instructions, which when executed by a processor of a computing system perform steps for quickly initializing a display, comprising: sending a first command to a display indicating that the display should store its current display settings, the first command including a first token, wherein the first command is sent by a host computer system to which the display is attached and from which the display is receiving a first video signal, the first command indicating that the host computer system is about to enter a sleep state, and wherein the display includes a video processor and registers that are configured according to the current display settings to display the first video signal, and wherein the first token is a value that is generated by the host computer system to represent characteristics of the first video signal and is different than the first video signal; in response to the first command, storing the current display settings with the first token before the display enters the sleep state, such that after the current display settings and the first token are stored, the host computer system and the display enter the sleep state; upon awakening from the sleep state, the host computer system detecting that it will be sending a second video signal that has the same characteristics as the first video signal; the host computer system sending a second command to the display, the second command including a copy of the first token to indicate to the display that the host computer system will be sending the second video signal that has the same characteristics as the first video signal; upon receiving the second command, confirming, when the display is in a subsequent wakened state, that the copy of the first token is the same as the stored first token indicating that the display can properly display the second video signal using the stored display settings; and restoring the stored display settings as actual display settings by configuring the video processor and the registers according to the stored display settings when the display is in the subsequent wakened state such that the display may commence displaying the second video signal using the stored display settings without performing a full detection and correction routine.
