  • Patent number: 9626741
    Abstract: Systems and methods dynamically configure a display (104) of an electronic device (102) to a desired display resolution and/or a magnification factor without noticeable impact on the user viewing experience. According to certain aspects, the distance between a user (100) and the display is measured (1002), and the desired display resolution is determined (1006) based on the distance. If a user is exhibiting (1008, 1010) symptoms of presbyopia, a magnification factor may be determined (1012). A request indicating the desired display resolution and/or magnification factor is transmitted (1016) to a server that supplies images, such as pictures or videos. The image is received (1018) from the server and displayed (1020) on the display. A focus area distance and/or a pupil orientation of the user may also influence the desired display resolution. Bandwidth, processing, and power savings may result through the use of these systems and methods.
