Below are some oscilloscope captures of the output waveforms for the USB13700 controller board. These were created as a reference for a user to verify the outputs of the board. They might be helpful for someone else needing to check the outputs also.

There was no display connected to the outputs and you can see quite a lot of overshoot and undershoot in the signals. With a display connected those should be reduced. Also don't exactly remember what the probe arrangement was. Also the outputs of the USB13700 board were set for 3.3V when taking these so scale appropriately if comparing to 5V outputs.
