Comment optimiser la taille de l’image et la distance
Consultez le tableau ci-dessous pour connaître des tailles d’image optimales
réalisables lorsque le projecteur est positionné à la distance désirée de l’écran.

Si le projecteur est à 3 m de l’écran, les tailles d’image peuvent varier entre
72 pouces et 79 pouces pour obtenir une image de bonne qualité.
Remarque : Nous vous rappelons que, selon la figure illustrée
ci-dessous, il est obligatoire d’obtenir un espace de hauteur de
133 cm lorsque le projecteur est situé à une distance de 3 m.
