Method for testing the operation of a monitor (1) used with medical equipment. The monitor is controlled using a reference signal. If it is operating correctly a reaction signal is generated in response to the reference signal. The reaction signal is detected by a sensor (2). If a reaction signal is not detected or if an unexpected reaction signal is detected the sensor can signal a fault condition. An Independent claim is made for a medical display monitor and alarm device with an arrangement for testing the monitor operation. If a fault condition is detected an alarm is generated.
