A system has video output connections capable of connecting to different display devices. The system has input connections capable of receiving image signal from multiple sources. A table of gamma values is indexed by both the display type and image source type. A software or hardware module applies a gamma correction from the table to the received video to transform it to have a gamma consistent with that of the display device. In a further embodiment, the images are encoded with a gamma identifier which is used to index into the table of system gammas. A video card that detects video source and display is also described. The video card utilizes a table of gamma values indexed by video source and display type and operating mode. Images are then corrected by the card to display properly on the display.
