Then, the mode setting signal from the microcomputer 3 is converted. The mode is a horizontal frequency divided into several frequency ranges, and this mode setting signal sets a rough screen size and screen position. 7 is a digital / analog converter (hereinafter,
D / A section) converts the screen setting signal from the microcomputer 3. This screen setting signal is a signal for adjusting contrast, brightness, screen position, and screen width by changing the DC voltage. Reference numerals 8, 9 and 10 denote circuits controlled by a microcomputer, and 8 denotes a mode switching unit for switching the constants of the output circuit of the deflection system for each mode. SW etc. are used. Reference numeral 9 indicates a video amplifier circuit, and 10 indicates a horizontal / vertical circuit.

Next, the operation when the conventional monitor device sets the screen based on the memory data will be described. The signal input from the input terminal 1 is input from the synchronizing circuit 2 to the microcomputer 3 as a horizontal synchronizing signal and a vertical synchronizing signal. The microcomputer 3 counts the frequency of the input synchronizing signal, measures the frequency of the input signal, and outputs the data of the corresponding frequency among some screen setting data already stored in the memory unit 4. , S / P section 6, and D / A section 7 are sent. The screen setting data sent to the S / P section 6 is
