1. A head-mounted display system (1, 1′), wherein the head-mounted display system (1, 1′) is configured to display images of a medical imaging device being a microscope or an endoscope, the head-mounted display system (1, 1′) comprising:
at least one head-mounted display (10a, 10b) comprising:
at least one display portion (11a, 11b),
a carrier member (20) having a forehead portion configured to be worn at a forehead level of an operator to movably support the at least one head-mounted display (10a, 10b), and
at least one control device (30, 30′) configured to: receive, using a SPS-connector (32), signals and/or processed data from at least one of an (Inertial Measurement Unit (IMU) and a Controller Area Network (CAN) bus and to control the at least one head-mounted display (10a, 10b) accordingly,
detect a position and/or orientation of the head-mounted display system based on the signals and/or processed data from the IMU,
adapt at least one of a contrast and a brightness of the images of the medical imaging device to be displayed in accordance with the position and/or orientation of the head-mounted display system;
wherein the at least one control device (30, 30′) is spatially separated from the head-mounted display (10a, 10b); wherein the at least one head-mounted display (10a, 10b) is pivotably supported by the carrier member (20) about a pivot axis (O) arranged in the forehead portion of the carrier member 20, and
