DEVICE FOR CORRECTING HORIZONTAL SIZE IN MONITOR

摘要

The present invention relates to a horizontal size correction device using a microcomputer to automatically compensate the horizontal size according to the input horizontal frequency to prevent the horizontal size of the monitor from being increased or decreased by the horizontal frequency output from the video card. However, the conventional horizontal size correction device has a problem in that it is not compensated linearly according to the change of the horizontal frequency, but only the specific frequency is corrected.;The present invention is designed to automatically compensate for the horizontal size according to the input horizontal frequency in order to prevent the phenomenon of increasing or decreasing the horizontal size of the monitor by the horizontal frequency output from the video card to solve such a conventional problem. It is a horizontal size correction device using a microcomputer.
