Abstract
A method for detecting a digital interface connected to an external device, and an image display device adopting the same are provided. The method for detecting a digital interface includes generating and displaying a menu for selecting a method for detecting a connection to an external device through a digital interface if the menu is requested, and detecting connection to the external device through the digital interface according to a digital interface detection method selected from the displayed menu. Accordingly, problems regarding digital interface detection can be prevented.
