    Well… you could zoom out.

  • "1280 x 1024 pixels is maximum for windows machines"... Huh? Mine is 1920 x 1200? May 9, 2014 at 15:00
  • @MarjanVenema, I mentioned resolution available in browserstack

  • @M.R: Don't understand. Why would that be different? Browser resolutions are dictated by the platforms on which they run? When I run my browser full screen, it definitely has 1920x1200 available? May 12, 2014 at 11:51

Well you can easily do it in Mozilla Firefox.

Try pressing Ctrl+Shift+M

Then you can choose from varieties of resolutions, also for your custom resolutions.

You can drag the sides to increase and decrease the resolutions.

Some links here on keyboard shortcuts and responsive design view

and the other on tilt which I guess you have it as an add-on and that is conflicting with the command.

For one time you you have to drag for custom 2560x1600 resolution and add it as preset. Then further you can always use this resolution settings.

  • Although I like the screenshot, ctrl+shift+m gives me the 3d-look instead of being able to choose resolution.

    you have installed tilt. Try disabling the tilt addon later on you can unable it. I have added some links in answers check out that as well.

  • Without checking, tilt is now standard in Firefox and you don't need the add-on unless that changed very recently.

    On Google Chrome and IIRC Internet Explorer zoom shortcuts are Ctrl-+ and Ctrl-- (Ctrl-Plus and Ctrl-Min). May 9, 2014 at 15:01

I think if you test 2560 x 1600 pixels or wider pixels it will same for the Full HD resolutions that mean 1920x1080 , so your site is responsive and supports up to full HD no matter the how screen size changes. If you want to test in multiple devices, you can use a few testers and the Firefox browser mobile tester.
