Techniques for changing image display properties

A computer-readable storage medium comprising instructions stored thereon, which when executed by a machine, cause the machine to:

• issue a request to change a refresh rate of a display;
• process a request to change a mode set, the mode set specifying the requested refresh rate of the display;
• in response to the request to change the mode set:
• ignore a command to blank a next frame buffer,
• request a copy of a frame in a current frame buffer into a second buffer,
• request to initialize a display engine to read video from the second buffer, and
• request to change a clock rate to the requested refresh rate;
• and
• indicate completion of the new mode set to an operating system.

A system comprising:

• at least one antenna;
• a display device;
• a memory to store a first and second frame buffers;
• an operating system logic;
• a display driver logic;
• and
• user mode application, wherein
• the operating system logic is to indicate a power mode change to a display driver logic,
• the display driver logic is to issue a request to the user mode application to change a refresh rate of the display device in response to support of multiple refresh rates by the display driver logic,
• the user mode application is to issue a video mode change call to the operating system logic in response to receipt of the request to change a refresh rate,
• the operating system logic is to issue a mode set call to the display driver in response to receipt of the video mode change call,
• the display driver is to perform actions to change the refresh rate and indicate completion of the mode set, and
• the operating system is to request to read frames from the second frame buffer at the requested refresh rate.
