1. A display apparatus comprising:
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 an output pattern of the gate driver so that the gate signals are applied one by one per one gate line or are applied one by one per two gate lines, based on an image input from the outside; and
a resolution resizer configured to change at least one of a horizontal resolution and a vertical resolution, based on the image input from the outside,
wherein, when a first image having a lower resolution than a displayable resolution of the display panel is input, the resolution resizer changes the horizontal resolution,
when changing of the horizontal resolution is performed by the resolution resizer, the timing controller controls the gate driver so that the gate signals are applied one by one per at least two gate lines,
wherein, when a second image having a lower resolution than a displayable resolution of the display panel and a higher resolution than a resolution of the first image is input, the resolution resizer changes the horizontal resolution and the vertical resolution, and
when changing of the horizontal resolution and the vertical resolution is performed by the resolution resizer, the timing controller controls the gate driver so that a portion where the gate signals are applied one by one per one gate line and a portion, where the gate signals are applied one by one per at least two gate lines, are provided.
