Steps to reproduce


Repro Steps:

Steps to reproduce

  1. Open IE on the high-DPI laptop screen
  2. Move IE window to the external monitor
  3. Notice the IE web page content scaling properly (Zoom level changes from 100 to 200%)
  4. Notice the IE back button, address bar and other chrome increasing in physical size
  5. Press F12
  6. Notice that every part of the F12 UI is too big on the external monitor
  7. Move IE back to the high-DPI display
  8. Notice that the F12 window elements now assume the correct size
  9. Unpin the F12 tools (Ctrl+P)
  10. Move the unpinned F12 window to the external monitor
  11. Notice that the UI elements appear too large on the external monitor, leaving very little work space

Expected Results:

Using the same setup, when I move a Word 2013 window from the high-DPI monitor to the external monitor, the Word UI scales in a way that retains the physical size of UI elements and fonts. I would expect IE to also scale its UI in a similar way. As Word works fine on the same setup, we can assume the OS settings for high-DPI scaling are set up correctly.

Actual Results:

    • There are several applications that appear to suffer from this issue, notably Powerpoint, Adobe products and Internet Explorer 11. I’ve managed to fix Powerpoint by adjusting the manifest but there’s no manifest I can find for IE. The only information on the web is to use a hex editor on the exe itself. This is seen here: http://superuser.com/questions/1095211/on-windows-10-why-are-some-programs-not-scaling-on-second-monitor/1099680

    • This issue affects multiple applications, as noted by Steve, I have managed to fix Skype for Business and PowerPoint by adjusting the application manifests, but several other programs (VMware Workstation, IE11) do not scale as expected.
      My setup is a Surface Pro 4 with external Dell 1920x1080 monitor.

    • Has there been any progress on this issue? I’m still experiencing it with a Surface Book and an external LG monitor.

      Edge and Chrome don’t have the same issue, just IE11.

    • Paul, I am having the same problem.
      My main display is 3840 x 2160 and extended screen is 1600 x 900. (Connected via HDMI).
      Have the same problem in IE11.
      MS Edge seems fine.
