I know the native resolution for MacBook Pro 2019 is 2560x1600. Using this resolution makes everything very small in Windows 10 and its needed to use scales (for example 200x). Another solution for this could be using a lower resolution.
Using 1280x800 seems perfect because it is exactly half in each dimension and it is expected that it does not need any adjustment because each four pixel maps to one pixel in this resolution.
But it seems there is a problem in the firmware of the LCD controller of the MacBook that makes the screen blurred in this resolution.
