External monitor turning dark after seconds.

Hi, im trying to use a external hdmi monitor with my m1 macbook air. I have bought a Verbatim usb-c multiport adapter with hdmi. When i connect any display with the hdmi connector the display works perfectly for 10 seconds and then only displays a black image. It's still recognized by macos and is not shut down. when i change the refreshrate in macos the monitor works again for 10 seconds and goes black again. I have tried different monitors and different hdmi cables. I tried the multiport usbc adapter on my asus laptop and it works as intendet with no problem. I have also tried the DisplayLink macOS Software with no success.

Any idea whats the problem here?

MacBook Air (2020 or later)

Likely the adapter is not compatible with Monterey. Does Verbatim specific say it works with Monterey?
