Display artifacts, such as muras, may be perceptible on an electronic display when an electronic device includes a radio frequency transceiver that outputs electromagnetic waves during an emission period and a display panel that writes to display pixels during a refresh period. The electronic device may also include a controller that is coupled to the radio frequency transceiver and the display panel and facilitates the reduction and/or elimination of overlap between the emission periods and the refresh periods to decrease the appearance of display artifacts. In particular, the controller may execute instructions to determine the duration of the emission period and determine the duration of the blanking period that occurs between the refresh periods. Further, based on the determined blanking period and emission period durations, the controller may instruct the radio frequency transceiver to adjust the timing of the first emission period, instruct the display panel to adjust the timing of the refresh rate, or both to reduce overlap.
