Second Monitor no longer works

[mahesh]

My second monitor stopped working after updating Ubuntu. Any suggestions to look at? It was working fine on the latest NVIDIA drivers but after doing a UBUNTU update it won't display. I can get dual display using the laptop screen and 1 external monitor.

NVIDA Version 510.47.03
UBUNTU version 20.04.4 LTS Focal
Kernel 5.13.0-30

Thank you
