Loading second display on 2 different monitor setups shrinks the higher resolution display to lower resolution displays size

Windows

-

Steps to reproduce:
1. Download latest attached project("ScreenTestScenery.zip")
2. Make sure you have 2 monitors with different native resolutions
3. Build for Standalone
4. Run the build and wait a few seconds

Expected result: both monitors display at their full resolutions
Actual result: display with a higher resolution shrinks to the resolution of the smaller resolution display

Reproduced on 2019.1.0a9, 2019.1.0b7, 2019.2.0a8
Not reproduced on 2018.3.9f1, 2019.1.0a1, 2019.1.a8

Notes:
- Not reproducible on identical monitors with different set resolutions
- Which display the build is started on has no impact

  1. This is a duplicate of issue #1159209

    Second display inherits first display's resolution when loading second display on a smaller resolution monitor

  1. Resolution Note (2019.3.X):

    While the symptoms are different, I verified this is indeed the same issue as https://issuetracker.unity3d.com/issues/second-display-inherits-first-displays-resolution-when-loading-second-display-on-a-smaller-resolution-monitor; the fix for that bug also addresses this problem

  2. Resolution Note (2019.3.X):

    Parent bug is a duplicated, which has already been fixed for releases:
    2020.1.0a3
    2019.3.0b1

    In our cases it looks like all screens get rendered at an aspect ratio that depends on whatever is defined in Windows as the 'main' screen.

    Also, in my case, it is actually reversed. The higher resolution display is used for both and the lower resolution screen cuts off.

    I also have seen this situation create a problem where the UI components can't be hit where they are rendered, so I believe this issue may also be from the same cause:

    Just a note on why this is important. For many art or live presentations, multi-display with different resolutions is vital when you have different video displays, such as a monitor, touchscreen, projectors, or different sized LED screens.
