I have a 15" macbook pro with 4 USB-C/thunderbolt 3 ports. I bought a multiport adapter from USB-C to HDMI and also a U2417H dell monitor which has 1 DisplayPort, 1 Mini DisplayPort and an HDMI port.
Every time I plug my mac into the monitor, I have to reboot it. Sometimes however, the mac will recognize that it is connected to a Dell monitor, but the monitor stays and with the message "No Signal."
I haven't tried a USB-C to HDMI cable or a DisplayPort adapter or cable because I want to ensure that there is not an issue with the monitor before I buy anything else for it.
The monitor works fine with a windows machine using the same HDMI cable.
What could be causing my monitor to have these issues?
