Using dual screens with Quadro K4000

I have a new workstation with Quadro K4000 and two 4K screens.
One screen is working. How do I create a dual screen system so one screen is extended to the other, doubling my work space?
Operating system is Red Hat RHEL8 Linux

Just plug it in?
Then open gnome control center->(devices)displays and arrange them.
Or doesn’t that work?

It shows only one display.
I thought both displays would be recognized automatically.
Now I am not even sure if the driver was installed. How can I verify that?

It should work automatically.
Please run nvidia-bug-report.sh as root and attach the resulting .gz file to your post. Hovering the mouse over an existing post of yours will reveal a paperclip icon.

I guess it wasn’t installed.
Trying to run nvidia-bug-report yield a “no such file or directory”
Can you point me to where I download the driver and how to install it?
Thanks

I’d recommend adding the rpmfusion repo:
https://rpmfusion.org/Configuration/
and install the driver from that:
