If you're able to move the second monitor to the left of the primary monitor, you won't run into this issue, because co-ordiates would always be negative from 0,0.

Hope that makes sense! ]]> https://www.displayfusion.com/Discussions/View/fullscreen-on-main-monitor-halves-2nd-monitor/?ID=81a1ed1e-b047-48f0-bb56-7627dfa4de87 Sat, 08 Feb 2020 12:37:44 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/fullscreen-on-main-monitor-halves-2nd-monitor/?ID=81a1ed1e-b047-48f0-bb56-7627dfa4de87 DisplayFusion Hello,

Is there any fix for this? My 2nd monitor cuts in half when I run a fullscreen game on my main monitor. It's kinda hard to explain, I can upload a video if needed.

FYI the monitors both have a 1440p resolution, one of them is in portrait mode.
The fullscreen application is being runned at a lower resolution then native (1080p).

Thanks! ]]>
