Hi, I have a MacBook Pro M1, and installed two monitors Dell U2720Q 4K displays connected to a Dell docking station D3100.
Cables HDMI high speed supplied with the monitors.

The image was not sharp at all and fuzzy... so, I tried changing and playing with the resolution and now the monitors turn blackened I get the following message:

"The current input timing is not supported by the monitor display. Please change your input timing to 3840x2160, 60HZ"

I have been trying to change it and was not able to do so. I tried al lot with Display Link and cannot find the 60HZ and monitor image quality. Anyone can help?:

Thank you,
