Provided are a display apparatus and a control method thereof which supports image data at differing frame rates, such as 60 Hz and 120 Hz, input from an image supply source. The display apparatus includes a first scaler which processes input image data; a second scaler which processes input image data; a display unit which displays thereon the image data processed by the first and second scalers; and a controller which selectively controls based on a frame rate of the image data to process the image data by the first scaler only, or to divide and process the image data by both the first and second scalers.
