Please Help - RHEL 7.3 NVidia offline install

Hi all,

I have a HP elite workstation to which i am trying to offline install the NVidia drivers. (The machine cannot go online at all)

I did download an rpm - 'nvidia-diag-driver-local-repo-rhel7-396.44-1.0-1.x86_64.rpm' and used the 'rpm -ivh' command to install.

This appeared to install it, however the driver is still on the old version. I am attempting to install the driver so that dual monitors will be available as currently the second display is not being recognised.

Please could someone give me a step by step install process as i am fairly amateur when it comes to RHEL
