A bi-directional HDMI to DVI cable can be used to solve your issue.   Connect Dell USB-C adapter to your workstation, connect HDMI connector end to Dell USB-C HDMI port, then connecting DVI connector end to your monitor DVI port. As for the off-topic question, I guess that uncountable thumbs-up "kudos" spelled with "s", it changed to "kudo" when became countable as 1 thumbs-up.  
I have an external monitor with Display Port, DVI and VGA ports; I want to use it with my Precision 5760 which has NVIDIA RTX A3000; Direct Graphics Controller Direct Output Mode has been enabled. I have a Display Port to HDMI cable and a little Dell USB-C to USB-A/HDMI adapter. The monitor is not detected. It is the only external monitor connected. I am using ports on the left as per the Precision 5760 External Display Connection Guide "The devices connected to the ports on the left side of the computer have priority over the ports on the right. While connecting external displays, it is recommended that you connect the displays to the left ports." I have tried the steps below with this monitor: Am I missing something, or should I conclude that my Display Port to HDMI cable is DOA?
