IMAGE OUTPUT APPARATUS AND IMAGE DISPLAY APPARATUS
A video display device outputs display device information including physical resolution of a display device included in the video display device and subpixel information to a hard disk recorder through HDMI (High Definition Multimedia Interface) cable. A receiver of the hard disk recorder receives the display device information and outputs the received information to an image processor. The image processor converts resolution of an image data stored in HD into physical resolution of the display device included in the display device information to output the image data. The image processor performs processing in subpixel level based on the subpixel information included in the display device information in converting the resolution.
