I have three monitors setup and they are working correctly with one exception:

Windows won't let me arrange my displays correctly. My third monitor is on top of the other two and whenever I try to arrange them, it reverts to being side by side.

What I'm attempting to do

What I get after hitting apply

After I hit apply, the third monitor falls down so they are all in one row.

I'm using an AMD Radeon R7 240 (latest drivers). Display 1 is connected to the card via HDMI, display 2 is connected to the card via VGA and display 3 is connected via a HDMI/USB adapter. I suspect that the adapter is contributing to the problem.

This is the adapter I am using: https://www.startech.com/AV/USB-Video-Adapters/slim-usb-3-hdmi-adapter~USB32HDES#dnlds

I have tried connecting the other displays with the adapter instead, but the issue persists.

How can I get Windows to allow me to arrange my third monitor on top of the others?

Update I just discovered that if I set #3 to portrait instead of landscape it works (unfortunately I want it in landscape mode). It also works if I lower the resolution of display 3, however I would like to make this work using the native resolution of the display.

  • I assume all display are working? Is it perhaps possible to arrange screens in the AMD graphics driver? I don't have AMD graphics, so I can't check. – Daniel B Aug 12 '16 at 19:10
  • @DanielB Yes all displays are working correctly. I have tried doing this through the AMD UI as well as through windows, no luck. – Mathew Tinsley Aug 12 '16 at 19:15
  • i have 3 monitors and I was able to arrange it the way you wanted. so it is definitely possible. – Keltari Aug 12 '16 at 20:22
  • Do you have on-board graphics you can attach the third monitor to? – JaredT Aug 15 '16 at 20:22
  • Try Actual Multiple Monitors (24.95$ with trial). – harrymc Aug 18 '16 at 16:49

AMD, Control Catalyst Center

  1. Download the correct/updated drivers.

  2. Download the Control Catalys Center software for your Windows and Radeon.

Regarding your update: Have you tried setting up the DPI manually? A correct Resolution can also help.

Note: What then you'd want to do is set each screen independently with "screen sizing", utilizing the buttons on the actual monitor.

  • I already have the latest drivers. It doesn't matter if I try arranging the displays through the Windows settings or through CCC, I get the same result. I'm not sure what you mean by "setting up the DPI manually". Can you clarify? – Mathew Tinsley Aug 13 '16 at 16:15
  • @mtinsley On the screen settings you can adjust height width.. you can also set the resolution, 720x 1280x 480x etc. – ejbytes Aug 13 '16 at 21:37
  • @mtinsley Added screenshot to illustrate resolution. – ejbytes Aug 15 '16 at 10:32
  • When I change the resolution, I can arrange display 3 on top of the others (just like when I change the orientation). However, this just introduced a different problem: Now it isn't using the native resolution of the monitor. I would like to make it work without having to use a lower resolution. – Mathew Tinsley Aug 15 '16 at 15:28
  • The menu Robin mentioned doesn't seem to exist (for me at least). I'm using the latest version of Windows 10 (anniversary update). – Mathew Tinsley Aug 15 '16 at 15:39

You should try doing this in Control Panel instead (Appearance and Personalisation > Display > Screen Resolution). Setting it in the Windows 10 settings application failed for me too.

    There is no "Screen Resolution" option under display in WIndows 10. There is a "Change display settings" option, but that displays the same setting interface that I've been using. – Mathew Tinsley Aug 15 '16 at 15:31
  • There is for me, i.imgur.com/ULkmt1A.png. The option on the left is named differently ("Adjust resolution"). With the path in my answer I meant as it appears in windows explorer at the top of the window – Robin Aug 15 '16 at 15:34
  • Welcome to Super User! This answer is better as a comment, but is at least helpful. I decided not to flag it for deletion, but it barely passes muster as an answer. – jpaugh Aug 15 '16 at 15:35
  • It is not there for me, using the latest version of Windows 10 (anniversary update). – Mathew Tinsley Aug 15 '16 at 15:37
  • I added a video to my answer, that might help you. I am not using the anniversary update by the way, but I don't believe Microsoft would remove such an option from the control panel. – Robin Aug 15 '16 at 15:43
