Steps to reproduce

I’m using Edge 38.14393.0.0 on an Acer Iconia W4-820 (1280x800 screen, 125% scale)

Pages are displayed correctly by Edge when Windows is in “Desktop” mode, but when in tablet mode, pages are rendered with incorrect DPI when in portrait display (pages look like they were layed out at the landscape width then zoomed out - fonts are too small)

I’ve attached screenshots of the Bootstrap CSS help page. In order:

  • Tablet Mode, Landscape (correct)
  • Tablet Mode, Portrait (incorrect, zoomed out)
  • Desktop Mode, Portrait (correct)

  • (The screenshots were in order when I uploaded them; they got all switched around now. Hopefully you can tell which is which by name!)

  • I have the same problem. I can reproduce the same wrong “behavior” in Edge. But this is something new, something that was updated since 1 or 2 months ago. All the pages I design have this specifications:

    media (max-width: 1024px) {
    @-ms-viewport { width: device-width; }

    And this worked just fine, since Edge was updated recently… The same thing happened before with Internet Explorer tablet app.
    I’ve tried many things to solve this problem, but nothing seems to work properly…
    I don’t know if its a bug (or something by design) but is looks like a bug (not behaving like other browsers).

  • I have the same issue. This is not the best behavior and has driven me to Chrome when browsing in tablet mode.
