Scaler Override View

From the Scaler Override view (Manual mode), an output can be selected under "EDID Source." Click
Refresh EDID to determine the attached destination device's resolution and then apply it to one or more
outputs which have been selected in the device tree on the left.
In some special installation cases, you will need to use the settings in the Scaler Override view to
override the automatic scaling and set (configure) a specific or a custom resolution for the display
monitor. When an Enova DGX Switcher is connected to a PC running DGX Configuration Software, the
program displays the resolutions supported by the selected destination monitor (or other destination
device) based on the set of supported resolutions in the monitor's EDID. Settings can then be selected
and applied to the output. When you select Manual in the Scaler Mode view, the selected connector sets
up the video scaler with factory default values (1280x1024 @ 60 Hz). EDID preferred resolution
parameters are used if available, unless scaler setup parameters were previously uploaded.
Important: If a device with an EDID (e.g., a video processor) is installed between the output and
destination monitor, see page 171.
Instruction Manual – Enova DGX 8/16/32 Digital Media Switchers
Maintain Aspect Ratio – This option maintains the incoming video's aspect ratio. The image
is scaled until the display's video fills either horizontally or vertically first. If the vertical
direction is filled first, then the video will have pillar box, black bars on the sides of the
display (on left in FIG. 89). If the horizontal direction is filled first, then the video will have
letter box, black bars on the top and bottom of the display (not shown).
Stretch to Fit – This option scales the video to fill the display in both the horizontal and
vertical directions (display on right in FIG. 89). Black bars do not show when Stretch to Fit is
selected.
