The Digital Visual Interface (DVI)
The Digital Visual Interface (DVI) is a video interface standard
designed to maximize the visual quality of digital display devices such
as flat panel LCD monitors, digital projectors and high-end video
graphics cards.
The Cisco codec contains a DVI-I plug that can transmit either digital
DVI signals or standard analog VGA signals, depending on what type
of monitor is connected.
DVI Specifications
Cisco DVI-I follows the VESA Monitor Timing Standard v1.08, also
knows as Display Monitor Timing (DMT).
VGA formats supported on DVI-I in
•
SVGA (800x600) 60Hz, 72Hz, 75Hz, 85Hz
•
XGA (1024x768) 60Hz, 70Hz, 75Hz
•
SXGA (1280x1024) 60Hz
•
HD720p (1280x720) 50Hz, 60Hz
•
WXGA (1280x768, 1280x800, 1360x768, 1366x768 (@60 Hz))
Supported DVI Cables
Cisco supports the DVI-D (digital only), DVI-A (analog only) and DVI-I
(digital & analog) cables:
•
DVI-D Single-Link - Transmits digital TMDS signals
•
DVI-A - Transmits analog VGA signals
•
DVI-I Single-Link - Transmits either digital or analog signals.
TMDS - Transition Minimized Differential Signaling is a technology for
transmitting high-speed serial data and is used by the DVI and HDMI
video interfaces.
DVI Cable Length
It is possible to extend existing DVI cables by the use of extension
cables. The maximum cable length however is 5 meters. Going
beyond that may result in quality loss.
