Κανάλι Προβολής Δεδομένων (DDC)

Για να γίνει ευκολότερη η εγκατάσταση, η οθόνη έχει τη δυνατότητα Τοποθέτησης και Άμεσης

Λειτουργίας με το σύστημά σας, αν και το σύστημά σας υποστηρίζει το πρωτόκολλο DDC.

Το DDC (Display Data Channel) αποτελεί πρωτόκολλο επικοινωνίας μέσω του οποίου η

οθόνη πληροφορεί αυτόματα το σύστημα σχετικά με τις δυνατότητές της, για παράδειγμα, τις

αναλύσεις που υποστηρίζει και τον αντίστοιχο χρονισμό. Η οθόνη υποστηρίζει το πρότυπο

DDC2B.
