Scaler Mode View
The HDMI Output Board supports SmartScale
®
Technology to ensure appropriate output resolution regardless of the type
of incoming video. For systems with special requirements, a Bypass option and a Manual (override) option for setting
custom resolutions are also available.
NOTE:
SmartScale automatically responds to the 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., h/v pixel
count, detailed timing, and color space). 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.
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."
NOTE:
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).
