Keep Flash Videos In Full Screen On Dual Monitors

Flash videos, like those on YouTube, don’t stay full screen if you click outside the video—say, if you’re doing work on a second monitor. Kind of annoying, right? A quick system file swap, however, fixes this problem easily.

Many dual monitor enthusiasts love to watch movies or television shows on their second monitor, but if those are web-based videos, Flash has to rain on our parade. Sure you can make the video go full screen on your second monitor, but as soon as you try to work on your other monitor, Flash will lose its full-screen view. Thankfully, blogger/browser patcher d.i.z. has made a one byte change to the Flash plug-in that will keep videos running full screen, even if you click outside them—and he’s made it available for download.

All you need to do is grab d.i.z.’s modified npswf32.dll file and replace the one located in C:Windowssystem32MacromedFlash or C:WindowsSysWOW64MacromedFlash folder on Windows 7 64-bit (though we recommend you backup the original file just in case). After a restart of your browser, all your Flash videos should exhibit the new behaviour (i.e., you should be able to multi-task without losing full-screen playback). You can still exit full screen mode by hitting the escape key or using the Flash player’s full screen button, of course.

  • Has anyone noticed that when dual-screening with windows 7, the new windows media player 12 will exit full screen if you maximise a window on the other screen?

    Annoying and I haven’t figured out a way to stop it happening.
