Abstract: PURPOSE: A vertical output circuit of a monitor is provided to vary a vertical driving signal outputted from a vertical driving integrated circuit(IC), which feeds back a vertical deflection current flowing on a vertical deflection coil and outputs the vertical driving signal according to an inputted vertical synchronizing signal, so as to automatically control the size of a vertical screen. CONSTITUTION: A vertical size detector(30) detects a vertical deflection current flowing on a vertical deflection coil(V-DY), and outputs a predetermined feedback signal for compensating the size of a vertical screen, according to changes of vertical deflection remaining amounts. A vertical driving integrated circuit(IC)(10) variably outputs a predetermined vertical driving signal, according to the feedback signal inputted after being outputted from the vertical size detector(30) and an inputted vertical synchronizing signal. The vertical size detector(30) comprises as follows. A photo coupler(31) detects the vertical deflection current and outputs a feedback voltage signal in proportion to the vertical deflection remaining amounts. A comparator(32) outputs a feedback signal indicating a lower voltage characteristic, as the feedback voltage signal of the photo coupler(31) is bigger than a reference voltage, and applies the feedback signal to the vertical driving IC(10).
