Viewport Ghosting When Using SOLIDWORKS with mixed resolution monitors

This article goes over the steps necessary to resolve an issue where the SOLIDWORKS viewport cascades and flickers when using multiple monitors with different resolutions(especially with 4k). This issue has been reported to the SOLIDWORKS development team under SPR 968986.



This issue has previously been associated with the high DPI scaling feature in Windows 8.1 and Windows 10. If you are using either Windows 8.1 or Windows 10 and are encountering the behavior pictured above, you will want to follow these steps:

1. Right click on your SOLIDWORKS shortcut and select "Properties". If you are using Windows 10 and do not have a shortcut for SOLIDWORKS on your desktop, you can access this "Properties" option by navigating to your Start Menu > All apps > Right click on your version of SOLIDWORKS > More > Open file location > Right click on the shortcut for SOLIDWORKS.

If you are not launching SOLIDWORKS from a shortcut on your desktop, it may be a good idea to go straight to the SLDWORKS.exe file located in your SOLIDWORKS installation location (default: C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS\SLDWORKS.exe). Right click on the .exe file and click on "Properties".

2. Navigate to the "Compatibility" tab in the new window.

3. Check the option for "Disable display scaling on high DPI settings" or with newer versions of Windows 10, click Change high DPI settings and then check the option to override high DPI scaling and set the drop down to Application.



4. Click OK twice to exit and apply the changes.

5. Restart SOLIDWORKS and re-test the issue.

  • This worked for me, I was not seeing it with HDMI plug, but using the mini-display port to a VGA port monitor had this issue. Great find!

  • Note that if SW is launched from somewhere other than the shortcut (e.g. by double-clicking a file in Windows Explorer), the "Disable display scaling on high DPI settings" setting will not be enabled and you may still see ghosting. If this is the case, make the above changes to the main SLDWORKS.exe program in the SW program files (C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS by default).

  • In certain Windows 10 profiles, "Disable Display Scaling on High DPI Settings" is replaced by a checkbox called "Override high DPI scaling behavior". To achieve the same effect as "Disable Display Scaling", check on "Override high DPI Scaling" and choose "Application" in the drop down menu.

  • Had an instance where this didn't work but repairing .net framework did the trick
