+## 1. Configure the Raspberry Pi
+
+If you plan on using an ultrawide monitor with a similar aspect ratio as the actual Dublin Bus displays (e.g. HSD123KPW2-D10), add the following lines to your /boot/config.txt:
+
+```
+framebuffer_width=1920
+framebuffer_height=720
+
+hdmi_ignore_edid=0xa5000080
+hdmi_group=2
+hdmi_mode=87
+disable_overscan=1
+hdmi_timings=1920 0 88 44 148 720 0 4 5 36 0 0 0 60 0 100980000 1
+```
+
+If your display's resolution is not 1920x720, you will also need to change the code to adapt to your specific size.
