Abstract
A method for generating, in a video signal receiver, an output signal for a display unit, comprising the steps of determining the display mode of the display unit, detecting the type of a video input signal received by the video signal receiver, converting the received video signal into an adapted output signal compatible with the display mode of the display unit, providing the adapted output signal to the display unit.

A computer-implemented method for generating, in a video signal receiver, an output signal for a display unit, it comprises the steps of:
- determining whether a display mode of the display unit is a mono display mode or a stereoscopic display mode, detecting whether the type of a video input signal received by the video signal receiver is a mono signal or a stereoscopic signal, converting the received video signal into an adapted output signal compatible with the display mode of the display unit, providing the adapted output signal to the display unit, characterized in that the display mode of the display unit is determined by providing an output test signal to the display unit, the test signal comprising at least two image regions (301-303), wherein a first image region (302) having a predetermined intended proper visibility (312) only in a mono display mode and a second image region (301, 303) comprises a visual indicator having a predetermined intended proper visibility (311, 313) only in a stereoscopic display mode;
- receiving a display mode identifier from the user.
A system for generating in a video signal receiver an output signal for a display unit, characterized in that it comprises:
- a display unit interface (202) configured to determine whether the display mode of the display unit is a mono display mode or a stereoscopic display mode, a signal type detector (201) configured to detect whether the type of a video input signal received by the video signal receiver is a mono signal or a stereoscopic signal, a plurality of video signal converters (204, 205) configured to convert the received video signal into an adapted output signal compatible with the display mode of the display unit, a signal output (209) configured to provide the adapted output signal to the display unit, characterized in that it further comprises a test signal generator (208) configured to provide an output test signal to the display unit, the test signal comprising at least two image regions (301-303), wherein a first image region (302) having a predetermined intended proper visibility (312) only in a mono display mode and a second image region (301, 303) comprises a visual indicator having a predetermined intended proper (311, 313) visibility only in a stereoscopic display mode;
- wherein the signal type detector (201) is configured to receive a display mode identifier from the user in response to the displayed test signal.
