Can't arrange displays correctly
I have three monitors setup and they are working correctly with one exception:
Windows won't let me arrange my displays correctly. My third monitor is on top of the other two and whenever I try to arrange them, it reverts to being side by side.
What I'm attempting to do
What I get after hitting apply
After I hit apply, the third monitor falls down so they are all in one row.
I'm using an AMD Radeon R7 240 (latest drivers). Display 1 is connected to the card via HDMI, display 2 is connected to the card via VGA and display 3 is connected via a HDMI/USB adapter. I suspect that the adapter is contributing to the problem.
This is the adapter I am using: https://www.startech.com/AV/USB-Video-Adapters/slim-usb-3-hdmi-adapter~USB32HDES#dnlds
I have tried connecting the other displays with the adapter instead, but the issue persists.
How can I get Windows to allow me to arrange my third monitor on top of the others?
Update I just discovered that if I set #3 to portrait instead of landscape it works (unfortunately I want it in landscape mode). It also works if I lower the resolution of display 3, however I would like to make this work using the native resolution of the display.
Solution 1:
AMD, Control Catalyst Center
Download the correct/updated drivers.
Download the Control Catalys Center software for your Windows and Radeon.

Regarding your update: Have you tried setting up the DPI manually? A correct Resolution can also help.
Note: What then you'd want to do is set each screen independently with "screen sizing", utilizing the buttons on the actual monitor.
