The disclosed embodiments provide a system that drives a first display and a second display mirrored to the first display from a computer system. During operation, the system obtains a framebuffer update for a first framebuffer associated with the first display. Next, the system performs a color-correction operation on the framebuffer update to obtain a color-corrected framebuffer update that enables color output from the second display to substantially match color output from the first display. Finally, the system uses the framebuffer update to drive the first display, and uses the color-corrected framebuffer update to drive the second display.
