No signal in a external monitor with MacBook Air M1

I had always use my Macbook with a LG 4K monitor and it works perfectly. But today with no idea, it stopped. I didn't change any settings, cable, nothing. I tested plug the same cable on other monitor and it works, I tested my LG monitor with other laptop and it also works. Final, I tried update de macOS but no success.

When I plug the cable on my Macbook, the system detects the monitor, the screen on my MacBook changes, but there is no video.
