My Mac Studio M2 doesn't recognize the LG monitor

My Mac Studio M2 doesn't recognize the LG monitor 43sq700. I was working with it for more than a year, and it suddenly stopped working. I connected the monitor to my Mac Pro, and it works perfectly. I tried everything to connect, but in no way. Thank you in advance for any help.

that LG v display appears to be a 4K display with refresh rates 58 to 62 Hz, and up to 10 bits/color.

interfaces include:

2x HDMI 2.0** limited to 4K at 50 Hz unless different color subsampling is used to push it to 60Hz.

1x USB-C with power delivery** limited to HBR2 at up to 4K at 60Hz without Display Stream compression.


¿What cables, adapters and docks are you using to make the connection?
