 The OpenIPC Bonnet includes an **HDMI-to-DisplayPort bridge**, allowing you to connect a low-latency external monitor—ideal for FPV, debugging, or touchscreen interfaces.

 To use the DisplayPort output:

+## Action Button
+
+The push button is mapped to **GPIO pin number 22** on Radxa zero 3. This works with SBC images for OpenIPC-FPV. **It will not work with Ruby FPV.**
+To remap the button to work with Ruby QA1 button, follow RubyFPV guidelines for custom Button mapping:
+
+1. Insert the SD card (that has Ruby flashed on it) into a PC;
+2. On the partition that shows up, add a new file named gpio.txt;
+3. Edit this new file and add 4 numbers, corresponding to the GPIO pin numbers you want to use for Menu/Back/Up/Down; 
+4. If you want to customize the GPIO pins for the Quick Actions too, add 3 additional numbers corresponding to the new GPIO pins to be used for QA1, QA2 and QA3;
+
+**The file content should be:**
+> 11,13,16,18,32
+5. Save the file. Ruby will use the new GPIO mappings.
