I have exactly the same problem. I'm using a micro hdmi to hdmi cable and a LG 4K TV. I tried a Pi 4, same cable, same TV, no issue at all with default resolution and refresh rate settings. So it must be some settings on the Pi 5 that caused this. So far I tried 1920x1080, 3840x2160, all frequencies that I can select, the issue still exists. The blackout is pretty random. Sometimes it happens every few seconds, and sometimes every 10 to 20 mins.
