Abstract: A display system that can solve the problem of an inadequate band in a connector or transmission path and that enables processing of a high-resolution image signal, includes a display device and an electronic apparatus that is electrically connected to the display device via a connector. The electronic apparatus receives or generates an original image signal indicating an original image that is to be displayed and supplies a plurality of divided image signals each indicating a respective image of a plurality of partial images into which the original image has been divided. The display device displays the original image on the basis of a combined image signal into which the plurality of partial image signals supplied from the electronic apparatus have been combined.
