Abstract: A display apparatus includes a display panel configured to display an image, a gate driver configured to supply gate signals to the display panel, a timing controller configured to control the gate driver; and a memory controlled by the timing controller, wherein the timing controller performs masking so that the gate signals are not output when a resolution of the image to be input is changed to a second resolution which is lower than a first resolution, and calculates a driving compensation value to display the image with the second resolution during a resolution change period.
