ABSTRACT:
A method and apparatus is directed to reducing jitter of the position of an On Screen Display (OSD) associated with a display device. Multiple horizontal signals are produced in response to a vertical flyback signal and a horizontal flyback signal for the display device. Each of the multiple horizontal signals has a different phase. One of the multiple horizontal signals is selected such that its rising edge of the selected horizontal signal occurs at a separate time when compared to the rising edge of the vertical flyback signal. By ensuring that the rising edge of the selected horizontal signal is not coincident with the vertical flyback signal, jitter is minimized in the position of the OSD.
