Same question .....
Quote:
You are probably using Windows 10 Anniversary Update onwards.
This is the current expected OS behaviour when both graphics card exists, the operating system will use the graphic card used for POST (boot, BIOS).
Should your platform allows disabling the onboard graphics totally, then this would work.
Otherwise, there is an OS improvement scheduled to address this in a future Windows 10 version so the indirect displays can suggest which card to use (=the best one, not the first one).
There is nothing you can change when the OS has booted to alter behaviour.
Kind regards,

This seems to be a standard response to a particular set of issues where you have a laptop with two graphics cards and the system selects the worse one.
Whilst I admit the fault may have been caused by the Microsoft Windows 10 Anniversary update 1607 (released 2nd August 2016), it concerns me greatly that this has still not been fixed over 2 years later.
Support has since ended for the Anniversary Edition 1607 (Home/Pro 10th April 2018), and we have just had the1809 released - and the problem is still ongoing.
So when is the supposed OS improvement scheduled to be released ?
