*** /home/user1/Documents/no_hdmi_bullseye

I have a Lenovo Mobile Workstation P15 with a Nvidia Quadro T1000 graphics card
and 1 hdmi port.
It came with Windows 10 Pro.
Everything works fine from Windows.

I partitioned disk and installed Debian Bullseye.
After installing, there is NO signal on the HDMI monitor.

When I power up the computer, the startup shell can be seen on BOTH monitors.
But when Debian boots up, the HDMI monitor goes black and only the laptop's
monitor registers.
When I navigate to Monitor Settings or Display Settings, no second monitor

I installed the Nvidia drivers after installing nvidia-detect.

Please help me resolve issue.
