U2723QE, not recognizing laptop USB-C

Question

Hello everyone

I have searched this community but not sure this issue has been answered, I have recently purchased the Dell U2723QE for work, when I attach my work laptop into the monitor via usb - c 90w it charges the laptop but says no signal is displayed, when going into device manager it recognizes the monitor as USB hub whereas when I plug it in via HDMI it recognizes it as a monitor as expected. It does sometimes say device may be restricted but this is not often.

I have checked the firmware but it’s up to date, I’m all out of ideas can anyone share there thoughts?
