摘要： A display apparatus displaying an image based on an image signal received from a source device is provided. The display apparatus includes a display, a display port interface to connect to the source device, a user input interface configured to receive a mode select command indicating one of a plurality of modes divided according to a vertical frequency ranges where the image is displayed, a first memory configured to store Display Port Configuration Data, a second memory configured to store Extended Display Identification Data, and a processor configured to transmit the EDID to the source device. In response to a mode select command being input, the processor controls vertical frequency information corresponding to a mode selected according to the mode select command to be stored in the DPCD and the DPCD storing the vertical frequency information instead of the EDID to the source device through the interface to be transmitted.

摘要： A display apparatus and an image output method thereof are provided. The image output method includes dividing a received image into a plurality of sub-images, correcting quality of each of the sub-images based on a contrast ratio calculated for the received image, and outputting the image by combining the corrected sub-images. Hence, the display apparatus can enhance luminance and chrominance which vary per sub-image segment in the received image.
摘要翻译： 提供了一种显示装置及其图像输出方法。 图像输出方法包括：将接收到的图像分割成多个子图像，根据对接收到的图像计算的对比度，校正每个子图像的质量，并通过组合校正的子图像来输出图像。 因此，显示装置可以增强接收到的图像中每个子图像段变化的亮度和色度。
