Configure the display
Use the Display settings to set the address for the display. Use the Columns and Lines fields to specify the number of columns and rows for the connected display.
Provide a meaningful name for the display in the Name field. This name is shown in the output configuration screens when assigning the display to flight simulator outputs.
Tip
Most displays have a default address of 0x27. To change the display address, solder resistors to the available A0–A2 pads on the driver board.
