I'm currently using my MacBook Pro with an external Benq Monitor (4K HDR) with a USB-Type C connection.
The problem is that it's also simultaneously charging my laptop over this same connection and the amount of power it can supply is much less that what my laptop needs. So, it doesn't charge properly.
Now, what I would like to do is disable the power output from the monitor and have the laptop only take charging from the Apple power adapter.
