A method is provided for use on an OSD-based (On-Screen Display) video display system, such as a VCD system, a super VCD system, or a DVD system, for the purpose of enhancing the resolution of cursor movement on the display screen of the video 5 display system. This method can help achieve the cursor movement resolution enhancement simply through software modifications without having to modify or add extra hardware to the existing video display system. By this method, the OSD blocks are partitioned into an array of subblocks, one subblock representing one resolution unit for the cursor movement. A number of predesigned sets of fragmented cursor patterns are provided and prestored in the display memory of the video display system. A corresponding set of fragmented cursor patterns can be retrieved for display in specified OSD blocks in response to a particular movement of the cursor over the display screen. When being displayed, these fragmented cursor patterns can be visually combined to appear as a full cursor pattern.
