button(s) to persist the setting(s).
Maintain Aspect Ratio and Stretch to Fit
Select one of the two aspect ratio options for the selected outputs:
Maintain Aspect Ratio
(default) and
Stretch to Fit
.
1.
Select the desired output(s).
2.
Select one of the Aspect Ratio options:
Maintain Aspect Ratio –
This option maintains the incoming video’s aspect ratio. The image is scaled until the 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. If the horizontal direction is filled first, then the video will have letter box, black bars
on the top and bottom of the display.
Stretch to Fit –
This option scales the video to fill the display in both the horizontal and vertical directions. Black bars
do not show when Stretch to Fit is selected.
3.
Click the Set button to the right. The selected aspect ratio will now persist to the Auto and Manual (override) modes.
The Bypass mode remains unaffected.
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 settings are used if available, unless scaler setup settings were
previously uploaded.
IMPORTANT:
If a device with an EDID (e.g., a video processor) is installed between the output and destination monitor, see
NOTE:
When the following timings are in the EDID data, the Scaler Override view will not display them: 720x400 @ 70 Hz,
720x400 @ 88 Hz, 640x480 @ 67 Hz, 832x624 @ 75 Hz, and 1152x870 @ 75 Hz. These timings can be entered in the program as
custom resolutions.
Get Current Timing, Apply, and Save Buttons
Get Current Timing
– Click to retrieve timing currently stored on the selected output. This allows you to either apply
those settings to other outputs that are connected to similar destination devices or to save the current timing as a
backup before making any modifications.
Apply
– Click to see how well settings work. Sends currently displayed settings to the destination. Selecting Apply
does not store or persist settings. If Apply was just selected and you close the program without saving any changes
in the settings, the program asks whether or not to save the applied settings.
Save
– Click to preserve currently displayed settings on the output connector. Sends displayed settings to an
output to store and persist them in the output’s memory. This button also persists the Scaling Override (Manual)
option on the output.
File Menu Options: Open File and Save to File
Open File – Select to load the settings from a file to the program.
Save to File – Select to save the currently displayed settings to a file. The file type available depends on the
selected view.
TIP:
When selecting outputs: select multiple, consecutive outputs by holding down the Shift key and clicking the first and last output
or select multiple, nonconsecutive outputs by holding down the Control key and clicking on each output.
Retrieving EDID timings From a Destination Device
NOTE:
DXLink Fiber hardware in Unidirectional or Data Link-lost Mode – EDID timings are not accessible as there is no return
path available to receive the information.
1.
From the Scaler Mode tab, select and set
Manual
(override) as the mode.

number connected to the desired destination from
the drop-down lists. The system is queried for all compatible devices found with the default (or last saved)
communication link setting (FIG. 162):
