Connecting Source Cables
14 m40L/m46L Installation & Configuration Guide
Using the DVI Out Connector
Digital Video Interface (DVI) digitally connects computers to their monitors or
interconnects to any displays.
The m40L/m46L converts the analog inputs to DVI 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. (However, even with DVI, loop-through is not infinite.)
• DVI inputs require much less setup and adjustment. You adjust the picture in
the first unit only, the unit with the analog input. Setup time is reduced.
Note: When the analog source is selected, the signal coming from the DVI out connector will
be accepted and displayed by other m40L/m46L displays. However, it does not strictly
conform to the DVI standard. Non-Planar units will not be able to display this signal.
Depending on which input is selected, the Digital Out connector 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 in order of the most desirable input to
the least desirable input.
Input Found on the Following Devices
DVI Computers with digital out capability
SDI Studio quality video equipment
Analog Computers, laptops
RGB and RGBS from video processors or other professional
equipment (may need BNC to DB15 adapter cable). These
may have separate sync, composite or sync on green.
