I tested it with a Notepad++ window here and it worked.

I'm not sure what you mean about the second function, could you attach a screenshot of the custom function settings? ]]> https://www.displayfusion.com/Discussions/View/game-window-span-multiple-monitors/?ID=019ba9f5-ce98-77f7-a5af-8041f354e52a#5 Fri, 16 Jan 2026 19:29:11 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/game-window-span-multiple-monitors/?ID=019ba9f5-ce98-77f7-a5af-8041f354e52a#5 DisplayFusion It is actually borderless window not borderless full screen ;]

I'm doing some further testing...
On windowed game it almost works. Almost.
1. Is it not possible to move window to a negative position and hide parts of it outside the screen?
2. Custom function move and resize seems to ignore some values I input (especially Y and height) and doing its own stuff. Also on game window going beyond screen down. ]]> https://www.displayfusion.com/Discussions/View/game-window-span-multiple-monitors/?ID=019ba9f5-ce98-77f7-a5af-8041f354e52a#4 Fri, 16 Jan 2026 18:32:23 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/game-window-span-multiple-monitors/?ID=019ba9f5-ce98-77f7-a5af-8041f354e52a#4 DisplayFusion I was not expecting that kind of answer ;]

That is actually a super usefull feature allowing to achieve Nvidia Surround usability without its problems. It is not only RDR2 it's every game. And ton of other uses, once you go there you never can go back.

Is there other way to use DF for multiple monitor gaming? ]]> https://www.displayfusion.com/Discussions/View/game-window-span-multiple-monitors/?ID=019ba9f5-ce98-77f7-a5af-8041f354e52a#3 Thu, 15 Jan 2026 20:24:45 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/game-window-span-multiple-monitors/?ID=019ba9f5-ce98-77f7-a5af-8041f354e52a#3 DisplayFusion We were able to reproduce this here and have added it to our list to look into to see if we can make it work in DisplayFusion. ]]> https://www.displayfusion.com/Discussions/View/game-window-span-multiple-monitors/?ID=019ba9f5-ce98-77f7-a5af-8041f354e52a#2 Tue, 13 Jan 2026 20:59:17 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/game-window-span-multiple-monitors/?ID=019ba9f5-ce98-77f7-a5af-8041f354e52a#2 DisplayFusion Resizing borderless full screen games hasn't been expected to work in the past as they are not regular windows, but it's interesting to know that there's another app that does it reliably. We will test Sizer and DisplayFusion with RDR2 and see what we can find out.

Thanks! ]]> https://www.displayfusion.com/Discussions/View/game-window-span-multiple-monitors/?ID=019ba9f5-ce98-77f7-a5af-8041f354e52a Sat, 10 Jan 2026 22:10:17 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/game-window-span-multiple-monitors/?ID=019ba9f5-ce98-77f7-a5af-8041f354e52a DisplayFusion I'm trying to migrate from Sizer 4.0. As of '26 it has more and more of problems with Windows 11 bringing unsoviable shiet...

I found some very nice features in DF.
But I am unable to solve my key problem of resizing game windows over three monitors.
This worked flawlessly in Sizer: move to -1200,0, resize to 4960 x 1600, game!

In DF it works on basic windows, like browser or windowed game.
But on borderless RDR2 it does not.
Force span does not resize it completely.
Tried custom function and scripted function... nothing works.

I can move it to -1200, 0 and have it sized as ~2500 x 1600.
I think I managed to have it moved to 0,0 and then being sized to 4960 x 1600, but then it is off screen.

I do not see a guide how to achieve games in borderless spanning over several monitors... ]]>
