1. A display apparatus forming a portion of a multi-image display system, comprising:
a display part configured to display an image at a specific vertical frequency corresponding to a vertical frequency of an
image signal multiplied by a number of display apparatuses aligned in a vertical direction; and

an image signal processing part configured to shift a start timing of writing the image signal into the display part based
on a location of the display apparatus within display apparatuses being aligned in the vertical direction to form the multi-image
display system,

wherein m denotes a number of display apparatuses being aligned in the vertical direction,
wherein, based on a reference timing 0 of a first-stage display apparatus, a timing of a second-stage display apparatus is
shifted by 1/m of the specific vertical frequency.
