Pas tout à fait ce que tu cherches, mais ...
Un logiciel PC permettant de connaître les capacités d'un écran, MonInfo.
Monitor Asset Manager is a Plug and Play monitor information utility that works under all 32-bit versions of Windows. It is fully multi-monitor-capable, and unlike similar reporting utilities queries the monitor directly rather than relying on potentially dubious information stored in the registry. In addition to providing detailed information on monitor color and timing characteristics, this compact utility (213kb) is the only program of its type to accomplish this.

EDID est en quelque sorte une fiche descriptive des capacités du diffuseur (formats audio vidéo traités …).
Une platine de salon lit l’EDID du diffuseur, découvre les capacités du diffuseur et n’envoie en conséquence vers le diffuseur que les signaux audio vidéo conformes à la capacité de traitement du diffuseur.
Extended Display Identification Data (EDID) was created by VESA to enable plug and play capabilities of monitors. This data, which would be stored in the DTV Monitor, describes video formats that the DTV Monitor is capable of receiving and rendering.
The information is supplied to the source device, over the interface, upon the request of the source device. The source device then chooses its output format, taking into account the format of the original video stream and the formats supported by the DTV Monitor. The source device (e.g., STB) is responsible for the format conversions necessary to supply video in an understandable form to the DTV Monitor.
