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...

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?

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.
