Video Operations
Adjusting the Display Region (ROI)
ROI (Region of Interest) is a function for limiting the display region beforehand.
As shown in example 1, when outputting to a display such as an LED display that does not use a 16:9 aspect ratio, you can use the ROI function to
specify the display region in advance, which lets you adjust the picture according to the region in which the video is actually shown.
Example 1: Video output to a 256 x 256 LED display
Input Format
1920 x 1080
Output Format
1920 x 1080
ROI
256 x 256
LED Display
256 x 256

Even in the case of example 2 where the resolution of the final display is 4K or greater, you can use multiple VC-100UHD to handle this. In this
situation, use the same settings for the scaler and ROI size on each VC-100UHD. For the ROI position, set this individually according to the output.
Example 2: Video output to an 8192 x 256 LED display
Input Format
4096 x 2160

You can select a color outside of the ROI range. This color can be used to define the respective boundaries when setting the final output and ROI.
1 . Select Root menu “Processing” 0 “Main Processing” or “Sub Processing” 0 ROI item.
2 . Turn the [VALUE] knob to set the ROI.
Parameter Explanation
ROI Enables/disables the ROI function.
Size H Sets the ROI’s horizontal size in pixels.
V Sets the ROI’s vertical size in pixels.
Position H Sets the ROI’s horizontal position in pixels.
V Sets the ROI’s vertical position in pixels.
Masking Color Sets the color of the area outside of the ROI.
3 . Press the [SETUP] button twice to return to the Root menu screen.
