Default Source Selects the default or primary video
input signal when the monitor is
connected to two active and valid video
sources. The monitor will automatically
determine the video format.
Auto Switch Source Turns the system's automatic video
signal input to On or Off. The factory
default is On.
Selecting Video Input Connectors
The input connectors are:
●
VGA connector (analog)
●
DVI-D connector (digital) (select models)
●
HDMI connector (select models)
The monitor automatically determines which inputs have valid video signals, and displays the image.
You can connect the VGA cable, the DVI-D cable, or both. If both cables are installed, the default
input selection is DVI. The HDMI cable is in place of the DVI-D cable. The source of input can be
switched using the Source Control option in the OSD menu. Switching from a VGA to an HDMI input
source may take several seconds.
