FIELD: communication.

SUBSTANCE: invention relates to display systems. Reproduction signal is output via a relay device to a display device. Circuit for monitoring connection to a preprocessing unit monitors, both a + 5V signal of a source device and HDMI, connected to an HDMI input module, and an HPD signal of a consumer device connected via HDMI to a second output module. Then, only when HPD signal transmitted by HDMI consumer device, is detected together with +5V signal, transmitted by HDMI source device, connection monitoring circuit enables a repeater function with respect to HDMI consumer device.

EFFECT: technical result is improved display system, configured to output reproduction signals, supplied from a reproduction device to two or more display devices, improved display device used mounted on head of user, and improved relay device, which provides relay between said reproduction device and said two or more display devices, including said improved display device used mounted on head of user.
