Auto Image submenu
The Auto Image submenu provides a means to turn the auto imaging on or off for
individual input selections.
If auto imaging is set to on, the ISS always sizes and centers the selected input to fill
the screen when a new frequency is input. If auto imaging is set off, the ISS sizes
and centers the selected input only when it is commanded using the Auto Image
main menu (a different menu path). See “Auto Image menu”, on page 3-6. Rotate
the Adjust [ knob while this submenu is active to select an input. Rotate the
Adjust { knob to toggle auto imaging on or off for the displayed input.

The Auto Image function and the Auto Memories function (see “Auto Memories
submenu“, on the next page) work interactively. Each function can be on or off,
giving four possible combinations, as follows:
• Auto Image on and Auto Memories on — The output signal is sized and
centered to fill the screen and these Auto Image parameters are saved as an
auto memory. The next time the unit encounters the same input signal, the
saved parameters are aplied automatically. When all 16 auto memories are
filled, the the oldest is overwritten by the newest.
• Auto Image off and Auto Memories on — The unit applies the default
values for the detected input resolution. If no further adjustments are made,
the Auto Memories function does not save an entry (all parameters remain at
their default settings). If you adjust the input manually or manually execute
an Auto Image, the Auto Memories functions automatically store the new
parameters.
• Auto Image on and Auto Memories off — An Auto Image function is
performed for each new input selected, but the parameters are not saved. The
next time the unit encounters the same input signal, Auto Image function is
repeated.
• Auto Image off and Auto Memories off — The unit takes no automatic
action when it detects a new input signal. Only Input Preset parameters are
applied, when recalled via an SIS command (see the Command/Response Table
for SIS commands, in chapter 4, “SIS
Programming and Control“).
Test Pattern submenu
The Test Pattern submenu lets you select from among several test patterns and
assigns the selected pattern to either or both outputs. The test patterns are helpful
when you are adjusting the connected displays for color, convergence, focus,
resolution, contrast, grayscale, and aspect ratio.
Rotate the Adjust { knob while this submenu is active to select a test pattern.
Rotate the Adjust [ knob to assign the test patter to the program output, the
preview output, both outputs or to turn the test pattern off. The available test
patterns are: Color Bars, crosshatch, 4 x 4 crosshatch, split grayscale, ramp,
alternating pixels, crop, and film aspect ratios 1.33, 1.78, 1.85, and 2.35 (figure 3-14).
The side-by-side crop and aspect ratio patterns available from the submenu vary
depending on the aspect ratio of the output rate.
