Yes, sometimes the device needs a reboot. I’m glad that helped.

@robertkwild, answering the question you asked at the time, because it was never really addressed: no, the “CEC error” was not the cause of the missing picture.

Before 2026.08.1 that card was built on libcec, which cannot select the kernel CEC device, so it frequently reported an error on a perfectly healthy Pi. It has been rewritten on the kernel CEC API, and System Info now separates a display that simply does not answer CEC, which is normal for most desktop monitors, from a real fault. So if you see that card reading “No CEC display detected” on a current release, there is nothing to fix.

Glad the reboot sorted it out.
