A magnetic resonance apparatus includes a magnet system (2) for generating a steady magnetic field (H) in a measuring space (28), an RF receiver circuit (10, 14, 16) with an RF receiver coil (10) for receiving RF signals emitted by an object arranged in the measuring space, a monitor (22) with a liquid crystal display (LCD) display screen (44) for image display, and a central control unit (18) which is connected to the RF receiver circuit and to the monitor for control in such a manner that information is applied to the LCD display screen. In order to prevent disturbing RF signals, produced by the monitor (22), from affecting the information obtained via the RF receiver circuit (10, 14, 16), the central control unit (18) is arranged to control the monitor in such a manner that information is applied to the LCD display screen (44) only during periods in which the RF receiver circuit is not activated. Generally speaking, the monitor (22) includes a signal processing unit (38) which is arranged to convert an image signal received on its input (40) into a screen signal suitable for supply to the LCD display screen (44) and to make this image signal available on its output (42). The output (42) of the signal processing unit (38) is then preferably connected to the LCD display screen (44) via a controllable switching unit (54), a control input (56) of which is connected to the central control unit (18).
