The DVI-D connector on this monitor uses digital video
information to provide higher speed for higher display
resolution. The results are more precise video displays without
manually adjusting screen display quality.
Signal Cables Included:
VGA (Analog) to VGA Connector (15-pin)
DVI-D Cable (Digital only) to DVI Digital Connector
Signal Connectors and Cables
There are six signal input connectors: two VGA connectors, two
DVI-D connectors which support TMDS digital video signals,
and two video connectors which support NTSC, PAL, and
SECAM formats. The monitor will automatically select the two
connectors which will be displayed on the dual channel monitor
using the automatic input selection mode described in the "Initial
Select Switch" section. Alternately, the monitor defaults can be
overridden and Channel 1 or Channel 2 inputs selected using the
On-Screen Display (OSD).
