The present invention provides a system and method for adjusting the brightness of a rear seat entertainment monitor for the rear seat passengers of a vehicle in conjunction with the open angle of the monitor. The brightness adjustment system of the present invention includes a monitor open angle input unit, a control unit, an image processing unit and a Liquid Crystal Display (LCD) panel unit. The monitor open angle input unit outputs a gearing amount corresponding to a current open angle of the rear seat entertainment monitor of the vehicle. The control unit calculates the current open angle of the monitor using the gearing amount, received from the monitor open angle input unit, and outputs a control signal required to set parameter values for an output screen image, corresponding to the calculated current monitor open angle. The image processing unit outputs a screen image of the monitor using corrected parameter values for an output screen image, in response to the control signal output from the control unit. The LCD panel unit projects the image, which has been output through the image processing unit, onto a screen.
