Abstract:
1. An apparatus for displaying a received video signal having a display mode that is determined to be either an out-of-range mode of a supported display mode of a monitor or a supported display mode of the monitor, the apparatus comprising: an analog-to-digital signal converting generating a sampling clock signal in response to received horizontal and vertical synchronizing signals and a received control signal, said analog-to-digital signal converter converting an analog signal into a digital signal representative of the received video signal in response to said sampling clock signal; a signal processor signal-processing the digital signals, output from the analog-to-digital signal converter, in response to the sampling clock signal, output from the analog-to-digital signal converter, the processed digital signal being applied to an input of a monitor; and a controller determining whether the received video signal has a display mode that is the out-of-range mode or the supported display mode in response to said received horizontal and vertical synchronizing signals, and outputting a corresponding control signal, said control signal being provided to said analog-to-digital signal converter for controlling a sampling rate of said sampling clock signal so that the digital signal input to said monitor and representing the received video signal is displayed on said monitor in the supported display mode.
