Hi Aleksander,
First step is creating a scene that matches the dimensions of the board and source in your region map that matches that as well. So a scene that 2600x208 and a source in the region map that is 2600x208.
The next step is dependent on the video processor feeding that display and how it is expecting to receive the image. In most scenarios the processor is expecting striped content but the dimensions of the stripes can vary depending on the physical construction of the video board. assuming the processor is expecting one 1920 x 208 stripe then a 960 x 208 stripe below, you would need to create two regions within the source you created in step 1. One region that is 1920 wide and another region that is 960 wide these two regions need to placed adjacent to one another within the 2600 wide source you have created. You will see the option to add a region just below the source canvas in the region mapper tool.
The third step is adding corresponding regions to a destination on the right side of the region mapping interface. Assuming you want this to play out of destination 1 then you would build matching regions on that 1920x1080 destination but in a striped configuration.
The fourth step is routing your source regions to your destination regions. Click on the source then in the source/destination mapping interface below select the desired region and using the drop-down menu assign it to the appropriate destination region.
