Display control system for determining connection of optional display unit by using palette
In a computer system having a flat panel as standard equipment and allowing a CRT as an optional unit to be connected thereto, first test data common to R, G, and B in all the palettes in a RAMDAC, and each of the R, G, and B display signal levels output from the RAMDAC is compared with a reference...

| description | In a computer system having a flat panel as standard equipment and allowing a CRT as an optional unit to be connected thereto, first test data common to R, G, and B in all the palettes in a RAMDAC, and each of the R, G, and B display signal levels output from the RAMDAC is compared with a reference level to determine whether a color CRT is connected. Furthermore, in all the palettes in the RAMDAC, the same data as the first test data is written for G, and data smaller than the first test data is written for R and B, and each of the R, G, and B display signal levels output from the RAMDAC is compared with the reference level to determine whether a monochrome CRT is connected. |
