Hello, I have a macbook pro Apple M3 Pro 16-inch Nov 2023 runnning MacOS Sequoia 15.7.1.

I currently have 2 HDMI monitors plugged into it. I unplugged both and plugged them into my Mac's HDMI port - confirmed that both are working.

If I go to settings -> Privacy & Security -> Screen and Audio Recording ... I have Display Manageer enabled.

My organization also has control of FileVault. I believe it is enabled.

Any ideas on what I can do to make my device display to both of my screens?
