Scaler Mode View - AMX DGX1600-ENC Hardware Reference Manual

Scaler Mode View

The HDMI Output Board supports SmartScale
incoming video. For systems with special requirements, a Bypass option and a Manual (override) option for setting custom
resolutions are also available.
In the Scaler Mode view, the default settings for the Current and Default scaler modes are both "Auto" (SmartScale) and the default
setting for Aspect Ratio is "Maintain Aspect Ratio."
* SmartScale automatically responds to the display's preferred EDID information and delivers a custom scaled image based not
only on the preferred resolution but also on the additional information associated with that resolution (e.g., horizontal and vertical
pixel count, detailed timing, and color space chromaticity). SmartScale eliminates the incompatibilities between sources and
displays operating at different resolutions by accepting the highest resolution of every source device ensuring every display
operates at its preferred resolution.
TIP: If the SmartScale functionality on the boards does not result in a good image, the reason may be because of the display device's
handling of the image, e.g., cutting the display short or adding too much space around the display. These types of concerns need to
addressed through the display device's control menu or by consulting the display device's customer support department.
Scaler Modes
Auto Mode
Auto Mode is the factory default setting and provides SmartScale Technology, which configures the output(s) to automatically scale
the video to the best resolution (up to 1920x1200) and the video settings for that display without manual setup. If the image is
satisfactory, no further action is required.
Bypass Mode
Bypass mode allows the video signal to pass un-scaled through the system.
If an output connector fails to read the EDID from its attached destination device on power up (i.e., no resolution data is available
from the device), the output connector reverts to the Bypass mode until the video cable is unplugged and then plugged in, at which
time it will attempt to read the EDID again.
NOTE: When Bypass mode is selected, both interlaced and replicated format can be passed.
Manual (Override) Mode
When you select Manual in the Scaler Mode view, the program sets up the video scaler with the factory default values (1280x1024
@ 60 Hz) for the selected outputs.
The Manual mode allows you to manually configure a specific or a custom scaled output resolution to send to the display
monitor(s). In this mode, the system ignores the EDID data being received from a display up to 1920x1200. When you select and
set the Manual (override) scaler mode, select the Scaler Override tab to configure the resolution (see page 273).
To change the Scaler Mode settings:
1. Select the Scaler Mode tab.

2. Select the desired output(s). (When selecting multiple outputs: either select consecutive outputs by holding down the Shift
key and clicking the first and last output or select nonconsecutive outputs by holding down the Control key and clicking on
each output.)
