UMG miscalculates DPI Scale for splitscreen.

I have seperate UMG Interfaces for both the top and bottom screen. When I stack my monitors one on top and one on bottom I expected the interface to scale to 100% so Player 1’s hud is completely on the top monitor and Player 2’s ud is completely on the bottom monitor. This is not the case the window over scales the interface and is applying the enitre window to DPI scales for both huds.

You have to change the settings to Horizontal and change you Curve based on screen width.

So:

Application Scale 1
Horizontal

Curve:
1280 , 0.667
1920 , 1
