Signal format: Selects the signal format for each input. Inputs 1 and 2 can accept either composite or
S-video signals. Inputs 3 and 4 can also accept component, RGBHV, RGBS, RGsB or RGB passive. On
inputs 1 and 2, the composite and S-video connections are internally wired together; therefore, either
composite or S-video can be connected to each input, but not both at the same time. Refer to
Installation on page 4 for the specific connections for each signal format.
The available signal formats are:
•
Composite
•
S-video
•
Component interlaced
•
Component progressive
•
RGBHV (RGB with separate horizontal and vertical sync)
•
RGBS (RGB with composite sync)
•
RGsB (RGB with sync on green)
•
RGBHVS Passive (RGB passive with either horizontal and vertical sync or composite
sync)
•
RGsB passive (RGB passive with sync on green)
To configure the inputs for a specific signal format, do the following:
1.
Press the ENTER or MENU button to access the main menu.
2.
Highlight input and press ENTER to access the input menu (use the
the appropriate menu command).
3.
Highlight signal format and press ENTER to access the input selection menu.
4.
Highlight the input you want to configure and press ENTER to access the signal format menu.
5. Select the signal format for each individual input (use the
signal format).
6. Press ENTER to save the signal format into memory.
CAUTION
It is critical that the signal format be selected properly for each input. If the input is not
properly configured to match the input signal, the scaler will not function properly and will either
display a distorted image or no image at all. Using the on-screen menu, operators can set / change
the input signal format at any time, even when another input is active. For example, an operator
can configure the signal format for input 1 while the display device is presenting a signal that is
passing through input 3. This method is required to deselect the RGB passive signal format, since
the on-screen menu cannot be seen while in this mode. These details are discussed in
Pass-through RGB video on page 22.
Aspect Ratio: The aspect ratio controls can be used to vary the relative image width and height. They
can be used to accommodate various input signal aspect ratios as well as output device aspect ratios.
The output aspect ratio is selected by choosing the appropriate resolution in the output menu (see
Output modes description on page 22).
Standard:
Anamorphic:
Wide Screen:
Wider Screen:
14
For Standard 1.33 input signals (sometimes referred to as full screen)
This setting provides vertical image squeezing to accommodate
anamorphically enhanced DVDs.
For wide screen 1.78 input signals (letterbox)
For wider screen 2.35 input signals (narrow letterbox)
