EDID Flow Through
The EDID Flow Through setting selects what EDID (Extended Display
Identification Data) is provided to the upstream source (i.e., a connected
computer). EDID is used by the source to determine what resolution and format
to output on the monitor connector. You can select the EDID originating from the
ROI itself, or the EDID from a downstream device connected to the ROI output
monitor connector.
• ROI-DP – The upstream source sees only the EDID of the ROI.
• ROI/Monitor – The upstream source sees the downstream device’s EDID
if a device is connected to the output monitor connector (HDMI, DP, DVI),
otherwise the source sees the EDID of the ROI.
This control is useful if, for example, a 4K monitor is connected to the ROI monitor
output connector, in which case the pixel clock rate might be higher than the ROI
can process, resulting in a red matte on the SDI output. Choosing the “ROI-DP”
EDID Flow Through setting can solve that problem. This setting replaces the
downstream device’s EDID with the ROI EDID. The source should then renegotiate
a display format that is within the operating range of the ROI.
Genlock
The Genlock control offers the following options:
• Free-run – Lock to internal clock
• Ref In – Lock to the Video Reference input
NOTE: The actual resultant Genlock status is reported to the right of the selection
menu.
H-Delay and V-Delay
These controls let you adjust H and V delay from the sync input, by dragging the
slider or entering values in the windows on the right. Horizontal delay is entered
in pixels, while Vertical delay is entered in lines.
