Abstract
A bandwidth-driven system, method, and computer program product are provided for changing a refresh rate of a display system. In use, a bandwidth associated with a display system is identified. To this end, a refresh rate of the display system may be changed for controlling the bandwidth.
Claims13
A method, comprising:
- identifying a bandwidth associated with a display system, the bandwidth including a first bandwidth and a second bandwidth, the first bandwidth in association with a first connection between a graphics-subsystem and a video memory, and the second bandwidth in association with a second connection between the graphics subsystem and a system memory;
- changing a refresh rate of the display system for controlling the bandwidth;
- and
- determining whether additional bandwidth is required;
- wherein, if it is determined that additional bandwidth is required, the refresh rate of the display system is decreased;
- wherein the refresh rate of the display system is decreased by changing at least one component of an inactive time period;
- wherein the bandwidth is compared to a user-configured threshold that includes a maximum amount of bandwidth that can be allocated by the first connection and the second connection, and the refresh rate of the display system is changed if the bandwidth exceeds the user-configured threshold by a predetermined amount.
