1. An apparatus comprising: a first logic to analyze a plurality of image frames of a video stream, to be displayed on a display device, to generate a first signal to indicate motion in the plurality of image frames; anda second logic to generate a second signal to switch a refresh rate of the displ
1. An apparatus comprising: a first logic to analyze a plurality of image frames of a video stream, to be displayed on a display device, to generate a first signal to indicate motion in the plurality of image frames; anda second logic to generate a second signal to switch a refresh rate of the display device from a first refresh rate to a second refresh rate based on: a change in power state associated with the display device and the first signal,wherein the second logic is to generate the second signal based on one or more of: a sensed temperature value or a sensed ambient light intensity value. 2. The apparatus of claim 1, wherein the first logic is to determine whether one or more additional image frames are to be inserted into the video stream. 3. The apparatus of claim 2, wherein the one or more additional image frames comprise one or more of: one or more interpolated image frames or one or more black image frames. 4. The apparatus of claim 1, wherein the power state corresponds to a power state of a computing device that is coupled to the display device. 5. The apparatus of claim 1, further comprising one or more battery packs to supply power to the display device, wherein the power state corresponds to a charge level of the battery packs. 6. The apparatus of claim 1, wherein the second logic is to cause the display device to switch from the first refresh rate to the second refresh rate during one of: a vertical blank period or a horizontal blank period. 7. The apparatus of claim 1, wherein the second logic is to generate the second signal based on one or more of: analysis of image data corresponding to the plurality of frames, one or more capabilities of the display device, one or more selections, or a power setting. 8. The apparatus of claim 7, wherein the one or more selections comprise a user selection or an application selection. 9. The apparatus of claim 1, further comprising a third logic to cause a display enable signal to be disregarded after the display device loses a lock of an incoming image signal. 10. The apparatus of claim 1, wherein the display device comprises a liquid crystal display, a plasma display, or a field emission display. 11. The apparatus of claim 1, wherein the first logic is to determine whether a backlight of the display device is to be turned on or off. 12. A method comprising: generating a first signal in response to determining that motion exists in a plurality of image frames of a video stream;determining change in a power state corresponding to a display device that is to display the video stream; andgenerating a second signal to cause switching of a refresh rate of the display device from a first refresh rate to a second refresh rate in response to the first signal and occurrence of change in the power state,wherein initiating the display refresh rate switching is performed based on one or more of: a sensed temperature value or a sensed ambient light intensity value. 13. The method of claim 12, further comprising determining whether one or more additional image frames are to be inserted into the video stream, wherein the one or more additional image frames comprise one or more of one or more interpolated image frames or one or more black image frames. 14. The method of claim 12, further comprising: analyzing the plurality of image frames; anddetermining existence of motion in the video stream based on the analyzing. 15. The method of claim 12, further comprising turning a backlight of the display device on or off. 16. The method of claim 12, wherein initiating the display refresh rate switching is performed based on one or more of: analysis of image data corresponding to the plurality of frames, one or more capabilities of the display device, one or more selections, or a power setting. 17. The method of claim 12, further comprising overdriving or underdriving a pixel of the display device based on a current value of the pixel and a previous value of the pixel. 18. A non-transitory computer-readable medium comprising one or more instructions that when executed on a processor configure the processor to: determine whether motion exists in a plurality of image frames of a video stream;determine change in a power state corresponding to a display device that is to display the video stream; andcause switching of a refresh rate of the display device from a first refresh rate to a second refresh rate in response to a determination that motion exists in the plurality of image frames and occurrence of change in the power state,wherein causing the display refresh rate switching is performed based on one or more of: a sensed temperature value or a sensed ambient light intensity value. 19. The non-transitory computer-readable medium of claim 18, further comprising one or more instructions that when executed on the processor configure the processor to determine whether one or more additional image frames are to be inserted into the video stream, wherein the one or more additional image frames comprise one or more of: one or more interpolated image frames or one or more black image frames. 20. The non-transitory computer-readable medium of claim 18, further comprising one or more instructions that when executed on the processor configure the processor to overdrive or underdrive a pixel of the display device based on a current value of the pixel and a previous value of the pixel.
