Datapath X4 User Guide

Conguring the x4
Factory Default Settings
The x4 stores a number of parameters to congure its operation. This allows it to operate stand alone
in a very exible manner. The congurations aect the input and output display modes as well as the
required partitioning of the input image between monitors.
By default the x4 is congured as follows:
Input EDID Preferred Mode: 1920 x 1080 x 60Hz (SMPTE timings)
Output monitor mode: Use Monitor Preferred Mode
Default : 1920 x 1080 x 60Hz (SMPTE)
Cropping Mode: 2x2 equal split (960x540)
No Rotation
The default settings are changed using the Windows® application provided, which can be run on any
Windows® platform and connected to the x4 via the supplied USB cable. A description of the use of
the application is provided in the x4 Control Application section.
The sections below describe the settings that are possible and why they may be needed. For details
on how to program the x4 hardware with your desired congurations, please see the x4 Control
Application section.
Conguring DVI Input resolution
Because the timings and resolution of the DVI input are set by the DVI source machine, the x4 can only
congure this indirectly by presenting a programmable “Preferred Mode” as part of its EDID
(Extended Display Identication Data).
Most graphics cards and HDMI appliances automatically select the “Preferred Mode” resolution and
timings presented by the x4 EDID, but they may need to be forced to re-detect if the EDID contents
are changed by the x4 application. This would typically be via a hot-plug event caused by
disconnecting and reconnecting the DVI input cable.
The conguration application will allow readback of the resolution that is currently being detected, as
well as the ability to read and write the internal EDID rom.
Monitor Outputs
The x4 can be congured to read the corresponding EDID of each monitor that is connected and to
drive out a signal that corresponds to the resolution, timings and mode (RGB or DVI) of the Preferred
Mode. This is the factory default conguration.
Please note that when dierent monitors are attached to the four outputs, each may advertise a
dierent Preferred Mode, therefore each output will be driven at a dierent mode.
