Abstract
The present invention provides an image/graphics data display mechanism for continuously displaying image/graphics data on dual display devices of a computer that contains a Display FIFO and a system memory directly accessed by the computer's CPU, wherein at least one of the display devices is running in a low-resolution mode, the mechanism comprising: determining which of the display devices is running in the low-resolution mode; receiving a power saving signal from the CPU; requesting an access to the system memory, and pre-storing the image/graphics data for the low-resolution device into the Display FIFO; and triggering the CPU power saving process according to a display timing scheme of the other display device.
