Abstract
A method in an electronic device includes detecting, by one or more processors from a first video stream captured by an imager, one or more images being presented by a remote display of an external electronic device. The method includes receiving, with a communication device operable with the one or more processors in response to the detecting, a second video stream comprising the one or more images being presented on the remote display. The method includes replacing, by the one or more processors on a local display of the electronic device, presentation of the first video stream with the second video stream. This works to eliminate visual distortion due to differences between the refresh rates of the display and remote display or asynchronous nature of the clocks in the electronic device and the external electronic device.
