to the intended audiences. To crop areas of interest, perform the following steps.
Step 1. Click the
Crop
button and use the cursor to select an area to crop. Upon releasing the left

A floating 5× magnifying window will display any nearby graphics at 5x and other
relevant cursor information (e.g., position and RGB value).

Click on and drag any of the 4 green cropping corners to enlarge/reduce the area just
selected. M
ay also use the keyboard’s top/left/right/down buttons to fine-tune the scope
of the area to be cropped without using the mouse button.
For additional fine tuning, manually enter the values of the

/

and
click the

position,
Width
, and
Height
are calculated based on module’s input display
size. The value for
Width
and
Height
must be greater than 20% of the panel width and the panel
height.
For example, if
the module’s input display timing is 1280×1024 @ 60Hz, then the panel width is
1280 and the panel height is 1024. The cropped window size must be greater than 256 (20% of
1280) × 204 (20% of 1024).
2. Depending on the display resolution, a minimal change in the cropping parameters (

/

) may not produce any noticeable effect.

It is highly recommended to set the displayed image to fill up the monitor’s whole screen (use the
monitor’s built-in display settings to fill the entire screen) to prevent black bar(s) from appearing after
cropping.
Step 2. Click the
Send Crop
button to send the cropped image back to the Pacific C-A for it to be
displayed on the output monitor through the
SDI OUT
connector.
Image scaling methods may differ per different graphics cards in the market, causing a pixel or more to be
left on the screen (residue from the 4 green corners). Adjust the value of

/

, and then
click the
Set
button to fine-tune the display area for the residue to disappear.
