Abstract

Various arrangements for monitoring and mitigating infrared (IR) interference from a display device are presented. IR emissions from a display device are measured the IR signaling characteristics may be adjusted to mitigate interference from the emissions. Calibration methods may be used determine display emission characteristics by displaying test patterns and video clips. Characteristics of the display patterns and video clips may be correlated to high IR emissions.
