Daisy-chaining Application, 8 Windows with Live Background
•
The HDMI source is connected to the HDMI Background input of the first MGP Pro
(unit B).
•
The HDMI output of the first MGP Pro (unit B) is connected to the HDMI
Background input of the second MGP Pro (unit A).
•
The first diagram in the row shows the HDMI computer, which is the input source.
The second diagram shows the display with one MGP Pro attached. The third
diagram shows the display connected to two MGPs. (On the MGP 462 Pro, this is a
4-window configuration.)
Setting up MGPs for Daisy-chaining
To set up one to three MGPs in a daisy-chain formation:
1.
Connect input sources to the MGP Pro to be displayed in the windows.
2.
Connect the HDMI output of the first MGP Pro (the unit farthest from the display) to
the HDMI Background connector of the second MGP Pro. If you are daisy-chaining
three units, connect the HDMI output of the second MGP Pro to the HDMI Background
connector of the third unit (the unit connected to the display, unit A).
3.
Configure the output as follows:
a.
Set the output resolution/refresh rate of the first MGP Pro (the unit farthest from the
display, unit C) to the native rate of your output display.
NOTE: Do not set this unit to the HDMI background rate.
b.
Set the output rates of the second and, if appropriate, the third MGP Pro to
Live
Background
Rate
. This setting uses the incoming HDMI resolution and pixel clock
as the output rate of the MGPs, which is essential in order to avoid any sampling of
the incoming HDMI signal.
NOTE: By default, the resolution provided in the Extended Display Identification
Data (EDID) is the last selected factory rate. To manually set the resolution
information provided in the EDID data, see the
