M16 Zephyrus frequently hangs randomly when USB C Monitor is attached.

I have a USB-C cable attached to the right USB C port. The monitor is an Asus gaming monitor with gsync and Display port 1.4. The internal monitor is disabled when external is in use. 

I also have 2 logitech mouse and keyboard USB wireless recievers attached to the other USB ports. 

Laptop appears to opertate fine when the monitor is not connected. however once I connect it Windows starts freezing up and hanging randomly. 

I highly suspect it's something to do with the USB controller and drivers. Not long ago I also tried connecting an external SSD with a good quality USB C cable and with no monitor attached and Windows locked up the same way.

I think i fixed it. Fingers crossed. 

I did a clean reinstall of Windows 11. Issues STILL continued.

But then I went to the Nvidia control panel - Manage 3D settings - Prefferred graphics processor - High-perfomance NVIDIA processor. 

No more stuttering hang ups or freezes.
