A monitor is disclosed, in which R/G/B signals provided from a video source are compensated to adapt to the color reproduction of the monitor, thereby obtaining the best picture quality. The monitor includes a video source for outputting one video signal, a color compensator for detecting characteristics of the video signal output from the video source and for comparing the detected characteristics with display characteristics of the monitor to compensate the color of the video signal, a video processor for processing the video signal output from the color compensator, and a display for displaying the video signal output from the video processor.
A computer system having a computer main body and a monitor displaying a video signal from the computer main body and a control method thereof. The control method includes storing a display information of the video signal displayed on the monitor based on EDID supplied from the monitor in the computer main body; determining whether the display information of an input video signal transmitted from the computer main body to the monitor is suitable for the EDID of the monitor; displaying the input video signal if the display information of the input video signal is suitable for the EDID and supplying an error signal to the computer main body if the display information of the input video signal is not suitable for the EDID; and processing the input video signal according to the display information stored in the computer main body and supplying it to the monitor if the error signal is supplied to the computer main body.
In the method and arrangement, a value of at least one image parameter of a liveview scene that is displayed on an imaging device display is determined. Based on the determined image parameter value, compensation value for the image parameter is determined, and the value of the image parameter is changed in accordance with the compensation value.
