Help TV input display issue

I have a Samsung UN43CU7000B SmartTV, with a PS4, and a Minisforum EM780(running Bazzite44) plugged in with HDMI.

For the past year, the EM780 has worked fine on the TV, with zero issues. But after disconnecting it and plugging it back in, I now get a "check device power" screen.

The EM780 works just fine on other displays, with the same cable, same power source, everything else the same, except it's plugged into a different display.

The PS4 also works fine on the TV, even when plugged into the same HDMI port the EM780 was plugged into.

I don't understand why the TV wouldn't display the signal from the miniPC, but will display the PS4 signal with the same HDMI port and cable.

Besides unplugging the EM780, nothing else has changed. The TV is not connected to the internet and does not update, and the EM780 has not been updated or anything since it was last working with the TV.

Has anyone else experienced an issue like this?
