An operating method of a display device includes detecting resolution of a display module for determining a border of a user interface reference frame, setting a border of a 3D spatial reference frame utilized by a pointing device to correspond to the border detected of the user interface reference frame, moving a cursor of the user interface reference frame displayed on the display module according to a shift of the pointing device, stopping controlling a shift of the cursor according to the shift of the pointing device when the shift of the pointing device exceeds the border of the 3D spatial reference frame, and resuming controlling the shift of the cursor in the user interface reference frame of the display module when the pointing device is back within the border of the 3D spatial reference frame. An advantage of the present invention is when out of the operating range, stopping controlling the cursor to lower the affect of offset, for allowing the pointing device to be applied in different areas/directions without having the cursor displayed on the display device to incorrectly reflect shift of the pointing device.
