An apparatus for processing image signals in a monitor system having an LCD module is enclosed. The apparatus includes an A/D converter converting analog R/G/B input image signals received into first 8-bit digital R/G/B image signals; a microprocessor determining whether a resolution of the input image signals is supported by the LCD module and generating a corresponding control signal, the resolution being determined using a horizontal/vertical sync signal received; an image converter converting the first 8-bit digital R/G/B image signals into second 8-bit digital R/G/B image signals based on the control signal if the resolution of the input signals is not supported by the LCD module, the second 8-bit digital R/G/B image signals being displayable on the LCD module; a scaler adjusting frame sizes of the first or second 8-bit digital R/G/B image signals; and a switch outputting the first 8-bit digital R/G/B image signals to the scaler or the image converter depending on the control signal. By using the apparatus according to the present invention, input images can still be properly displayed on the LCD module even if its resolution is not supported by the display module. In such case, the images signals are processed in the image converter in order to generate displayable image signals. On the other hand, if the display module supports the resolution of the input images, they directly get displayed on the LCD module without going through the image converter.
