Connecting Source Cables
The three types of picture sources are:
• Analog computer (from UXGA
down to VGA)
• Digital computer
• Video (optional with VIM)
• Composite (NTSC, PAL or
SECAM)
• S-Video (50Hz or 60 Hz)
• Component (480i, 480p, 576i, 576p, 720p, 1080i)
• SDI (Serial digital interface inputs from 480i to 1080p)
Digital Video Interface (DVI) is a standard for digitally connect-
ing computers to their monitors or for interconnecting displays.
The m40L/m46L converts the analog inputs to the DVI standard
and makes this available at the Digital Out connector. This
means you can bring in a picture source - UXGA, SXGA, VGA,
1080p - to the first display and connect the rest of the displays in
the loop with DVI. The advantages of DVI are:
• DVI is less subject to picture degradation than analog methods
of loop-through. (Even with DVI, loop-through is not infinite.)
• DVI inputs require much less setup and adjustment. You adjust
the picture in the first display only, the display with the analog
input. Setup time is reduced.
Depending on which input is selected, the Digital Out connec-
tor will show the picture from the analog input or the digital
input.

Selecting the Correct Input

The following table gives you common examples of which
devices have which inputs. In terms of input quality, the table is
ordered from the most desirable input to the least desirable
input.
