PYNQ: PYTHON PRODUCTIVITY FOR ZYNQ

Problem while trying HDMI Introduction

I am trying the HDMI Introduction in base/video/.
My setup is

  1. Connecting laptop HDMI output to PYNQ-Z2 HDMI input
  2. Connecting PYNQ-Z2 HDMI output to monitor VGA via an adapter.
  3. Laptop OS is Ubuntu 18.04
  4. Laptop display setting is “join-display”
  5. I have make sure the HDMI output on my laptop is working.

However, the PYNQ system doesn’t detect the input from my laptop.
