I have a quad-monitor setup (two stacked rows of two monitors) and a PC running Windows 10.


The problem is that the intersection point of the monitors never lines up perfectly. The four screens are identical and I fiddled with the display arrangement extensively, but regardless of how much I play with it, there always seems to be a gap (as shown in the second picture below).

The thick black line shows the separation between the top left and bottom left screens. What it doesn't show is that the bottom left and right screens are also slightly offset from their top counterparts. The right side of the bottom left screen is at the light grey outline of the dark grey window, while the top left screen's right side is shown by the faint change in blue tones.

The second image of the intersection highlights the bad separation in red (emphasis of intersection problem in dark red) and the good display junctions in green. The top screens both need to move left and the top left screen needs to move down. Easy in theory, impossible in practice?

How can I remove this gap?

    You do it more carefully. My eyes can see there is a slight issue where you've placed Monitor 2 just to the right of its proper line up, and this is confirmed in your other image. Often I find it helpful to move one of the monitor icons in this tool to a completely different location and then rearrange the rest around it again. – music2myear Mar 11 '19 at 22:06
  • Thank you @music2myear. Unfortunately, even if I do manage to line them up exactly perfectly, when I click "Apply" the displays move ever so slightly to set them just off one another. – ctwheels Mar 11 '19 at 22:09
  • Delete and reinstall the graphics driver? – music2myear Mar 11 '19 at 22:10
