PURPOSE: An apparatus for adjusting a screen of a video device is provided to automatically set or update an input video adjusting value according to a difference of an output video adjusting value in a video device supporting reproduction for video sources of various signal modes, thereby shortening work time for screen adjustment. CONSTITUTION: An analog screen adjustor(110) adjusts and outputs an analog video signal according to a set analog output video adjusting value. An ADC(Analog-Digital Converter)(121) converts the analog video signal into a digital signal and outputs it. A controller(141) reflects the difference between analog and digital output video adjustment values to determine a feedback adjusting value for adjusting an input video signal. An input video adjusting value setting unit(151) sets or updates the analog input video adjustment value according to the feedback adjusting value. |
