Assignee: DELL PRODUCTS L.P.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 7:
8. A method for presenting visual images at a display, the method comprising:
presenting visual information at the display with a first refresh rate;
applying a first gamma lookup table to a first multiplexor input from a first SRAM to adjust the visual information for presentation at the first refresh rate;
commanding presenting of the visual information with a second refresh rate to a selector of the multiplexor;
in response to the commanding, applying a second gamma lookup table to a second multiplexor input from a second SRAM to adjust the visual information for presentation at the second refresh rate;
presenting the visual information at the display with the second refresh rate;
storing the first gamma lookup table in the first SRAM, the first SRAM integrated in a scalar of the display;
storing the second gamma lookup table in the second SRAM, the second SRAM integrated in the scalar; and
integrating the multiplexor in the scalar having plural inputs that accept the visual information, one of the inputs interfacing with the first SRAM and one of the inputs interfacing with the second SRAM, the multiplexor configured to have each input selected as an output with gamma adjusted visual information by a single command to the multiplexor selector.
