NOTE: H and V delay adjustments are only available when the SDI Out Format is

compatible with the current sync input reference.

EDID Flow Through (ROI-DP Model Only)

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 Genlock status is reported to the right of the selection menu.
