For surrounded displays the resolution is 11520x2160@60Hz.
For the rest three monitors it’s standard 3840x2160@60Hz.
This problem with gaps also existed on a 1050ti, which also supports 7680x4320 as top resolution, where I put three monitors at surround mode at 5760x1080 resolution.
So I bet it’s not the problem of the resolution per se.
And just as an experiment, I will put all my monitors at 1080 vertical resolution to see if it will make any difference:
And just as I thought - the gaps are still present:
I cut the image, and showing only left and central monitors of the surround solution. But I think it’s visible that I put the resolution of surround displays at 5760x1080, and other monitors at just 1920x1080, and windows are maxed out (I hope the icon next to the X button is still visible, despite the fact that forum engine resized the image, and it is showing that the windows are maximized), and still the gaps between the windows, or between the edges of the screens are also visible (well, if we discount the left monitor, and three top ones since I cut them out).
Nothing. The gaps still will be present:
I actually read your request wrong, and disregarded the words you said about making 1050ti’s monitor a primary one, and now I made it. The DP monitor of 1050ti’s is the primary one now, and the problem still stands:
And not only it still stands, but it somehow got even worse. Note the gap between nvidia control panel window and the browser window. Both windows are maxed out.
And I’ll make the nvidia control panel more visible, because I don’t think it’s visible enough in the previous screenshot:
And I’ll show you the bezel settings, just in case you’ll ask for them:
And I think the problem is not actually the surround, but maybe windows itself, or rather it’s windows (actual GUI windows) manager.
