Scaler Override View - AMX DGX1600-ENC Hardware Reference Manual

3. Click any or all of the following:
The desired Current and Default scaler modes (for explanations of the three modes, see the previous page)

The Aspect Ratio of the display (for an explanation of the aspect ratio options, see below)

4. Click the appropriate Set button(s) to persist the setting(s).
Maintain Aspect Ratio and Stretch to Fit
In the Scaler Mode view, you can select one of the two aspect ratio options for the selected outputs: Maintain Aspect Ratio (default)
and Stretch to Fit.
To set the aspect ratio:
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 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. 144). 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. 144). 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 page 281.
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 button – 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 button – 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 button – 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.
