I have recently install 22.04 Ubuntu OS and I lost external monitor connectivity. I have tried few things but stuck.

I turn off wayland setting and turn on X11 And whenever I go to Settings > About my laptop freeze.
Additionally, I don't see display layout to setup monitor. I have Dell Dock and tried with DP1 and HDMI cables but didn't work.
I tried all possible solution, purge and install nvidia drivers, ubuntu-drivers autoinstall, OS re-install with safe graphics.
Appreciate your time.
EDIT
I have multiple drivers from the Additional driver window. I tried green highlighted drivers.
What I did?
- Select drivers and install it. Click on restart now button.
- After restart, open a terminal and run command
sudo ubuntu-drivers autoinstall
. Afterwards, reboot. - Go to Settings > Display. No effect. Same window as previous.
