Seems Lenovo has no proper Display-driver for the AiOs of the M-Series.
I'm having installed all updates with the newest version of the Lenovo System Update tool.
But the display still has that generic pnp driver .. with no options

You do not give your specific model, but try downloading the drivers manually from the support site linked below, which if not for your exact model, you can change if needed to match your model using the options at the top of the window.
