I use different scaling levels here, and having to change those would be more disruptive (for me anyway) than dealing with the gap.

We also may be able to fix that gap on the right-side of the left monitor, I've put that on our list to investigate, as this behaviour should only actually affect the left edges of windows. ]]> https://www.displayfusion.com/Discussions/View/app-not-filling-entire-split/?ID=42860187-e0b5-48a5-b003-fd081362e164#5 Fri, 08 Nov 2019 20:59:06 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/app-not-filling-entire-split/?ID=42860187-e0b5-48a5-b003-fd081362e164#5 DisplayFusion So really all I need to change is find a scaling level that works when both monitors are connected or just leave it the way it is and not worry about it. ]]> https://www.displayfusion.com/Discussions/View/app-not-filling-entire-split/?ID=42860187-e0b5-48a5-b003-fd081362e164#4 Fri, 08 Nov 2019 20:40:34 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/app-not-filling-entire-split/?ID=42860187-e0b5-48a5-b003-fd081362e164#4 DisplayFusion Ah yep, sorry about that! So, the reason for that gap is because the monitors are different scaling levels. When DisplayFusion calls the Windows API to set a window position, the top-left corner is actually about 7px to the left of what you can actually see on the window, because Windows 10 makes the borders invisible.

Normally what we do is move the window over by 7px, but because of the scaling difference, if we do that, it hangs on the other monitor and Windows returns the wrong scaling level ]]> https://www.displayfusion.com/Discussions/View/app-not-filling-entire-split/?ID=42860187-e0b5-48a5-b003-fd081362e164#3 Fri, 08 Nov 2019 20:23:40 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/app-not-filling-entire-split/?ID=42860187-e0b5-48a5-b003-fd081362e164#3 DisplayFusion It should be part of the original post. ]]> https://www.displayfusion.com/Discussions/View/app-not-filling-entire-split/?ID=42860187-e0b5-48a5-b003-fd081362e164#2 Fri, 08 Nov 2019 18:31:19 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/app-not-filling-entire-split/?ID=42860187-e0b5-48a5-b003-fd081362e164#2 DisplayFusion Could you attach a copy of your DisplayFusion troubleshooting info?

It seems to be on the junction between the 2 physical monitors. For reference I have 4 split areas 2 on each of my 2 monitors. It's not all apps. Seems to just be Microsoft Mail app and adobe Acrobat DC Pro. Any thoughts on how to fix this? Screenshot and Log info attached. ]]>
