The screen works with the CM4 IO board, the carrier board works with any other screen but this little 7" touch screen (1024x600). Not sure what I am missing. I have tried using HDMI Boost and tried HDMI safe. I did find that my clock pins were miss wired. But this did not affect other displays and on correcting it on board, there was no improvement. I did try a 2nd copy of the same screen.
