2.3.2 DVI-1 / DVI-2 Interface
The digital video inputs use the standard dual-link DVI interface. Dual-link DVI is necessary to support
the high data rate (dot clock) as required by this high resolution of 2048 x 2048. However, the monitor
also supports lower resolutions (e.g. VGA, SVGA, XGA, SXGA, UXGA, etc.) using a single link DVI
cable. This feature can be useful during boot up on some machines that use a lower resolution during
start-up.
The monitor provides EDID information (Extended Display Identification Data) to the host system
(workstation) via the DDC (Display Data Channel) protocol. This data includes, in addition to the
standard VESA timing, a special timing for 2048 x 2048 @ 60 Hz that is designed to use pixel
frequencies below the DVI maximum.
If the connected workstation/graphics card does not support DDC, it can be configured manually as
described in section 5.7 on page 55. In addition to this specific timing, all others timing that are part of
the DVI specification are displayed.
Video cables up to 5 meters in length may be used for the connection between the graphics card and
the display.
