Bonjour le Forum,

J'ai besoin de votre aide.

Je me casse les dents sur un moyen de récupérer le serial number d'un écran via WMI.

J'ai testé la classe root\WMI\WMIMonitorID et le serial number et d'autres trouvés sur Internet.

La chose étrange est que je ne retrouve pas ce serial number dans HKLM\SYSTEM\CurrentControlSet\Enum\DISPLAY\ au niveau du registre.

Des idées ?

Cordialement,


Miistik

Bonjour,

Merci pour ta réponse hackoofr.

Cependant, j'ai déjà testé le premier script et j'ai fait la même démarche que ton second.
Sans résultat.

EDIT : en fait, ton second script retourne bien le EDID_SerialNumber qui correspond à ce que je recherche.
Je m'excuse donc pour avoir lu trop vite ton script (pour ma défense j'en ai lu et testé un bon paquet).

Reste plus qu'à le simplifier pour extraire que EDID_SerialNumber
