Scaling
If the DVI source video frame aspect ratio is not the same as the output video
format frame aspect ratio, the FS2 scales the input frame size based on the
current Upconvert (Video Menu 6) or Downconvert (Video Menu 7) mode
selection.
If the FS2 output format is set to a Standard Definition (SD) format (525i/59.94 or
625i/50), the current Downconvert mode is used to determine the frame scaling
mode.
If the FS2 output format is set to a High Definition (HD) format (anything other
than SD), the current Upconvert mode will be used to determine the frame
scaling mode.

Frame Scaling
Letterbox
4x3 Pillar
Scale the input frame until the longer dimension (H or V) touches the output raster
edges. The shorter dimension is filled with background video. Maintains the
original pixel aspect ratio.
Crop
Wide Zoom
Scale the input frame until the shorter dimension (H or V) touches the output raster
edges. The longer dimension is cut off (cropped) to fit the output frame. Maintains
the original pixel aspect ratio.
Anamorphic
Full Screen
Scale the input frame independently in H and V until both dimensions fill the output
raster. No cropping or background fill is required, but the original pixel aspect ratio
may be “stretched” to fill the output raster.
14x9
14x9 Pillar
Compromise between Letterbox and Crop modes: some background fill may be
required in the shorter dimension to fill the output raster (but not as much as
Letterbox mode), and some cropping may be required in the longer dimension to
fit the output raster (but not as much as Crop mode). Maintains the original pixel
aspect ratio.
Auto AFD
LB to Full
When used with “computer format” inputs these modes default to Letterbox / 4x3
Pillar behavior.
Genlocking
The FS2 does not genlock (synchronize) to computer format video inputs.
If a computer video input feeds Video Processor 1 or 2 and the current
Genlock Source (System Menu 8) is set to Vid1 Input or Vid 2 Input, the system
automatically defaults to Free Run mode. You can select Reference as the Genlock
Source and apply a broadcast video signal to the Reference input if you wish to
genlock to video rather than use Free Run mode.
Getting Your Computer Working with the FS2
Getting your computer to work with the FS2 is much like getting your computer
to work with a second monitor. Here’s the recommended procedure:
1. Turn off the computer and the FS2.
2. Connect the computer video output to the FS2 HDMI input.
3. Turn on the FS2 and wait for it to boot completely.
4. Turn on the computer and wait for it to boot completely.
5. In the Windows 7 “Display” Control Panel, navigate to “Screen Resolution,”
and confirm that a second monitor for the FS2 is displayed. Click on the
“FS2” monitor and adjust the settings as desired.
