About the Scaler
The DDS 100 digital display scaler converts high-resolution input
signals to one of several output resolutions. The scaler was designed
especially for displaying images on projectors with limited display
resolutions, such as LCD (liquid-crystal display) projectors, DLP (digital
light processor) projectors, and plasma projectors.

Features
• Autoscanning — Automatically recognizes and converts the incoming
computer image, up to 1600 x 1280 resolution, 100 kHz horizontal
and 120 Hz vertical scan rates.
• Executive mode — Locks out all menu functions. When executive
mode is active, the centering controls and the RS-232 port are still
active.
• Freeze — Locks the output display to the current image. When the
freeze function is active, the freeze LED (light-emitting diode) is
lit.
• High-quality color sampling — Uses 24-bit sampling and provides 8
bits per color, for a total of 16.8 million colors.
• High-quality zoom control — Uses increased pixel clocking for
variable zoom, providing better quality of the displayed image.
• Horizontal and vertical controls — Provides controls for sizing and
centering the image. This provides increased flexibility for
panning across the image while zooming.
• Horizontal and vertical filtering — Provides four levels of horizontal
filter control and ten levels of vertical filter control. These user-
selectable filtering controls reduce flicker and ensure that no
picture detail is dropped during scaling.
