Dual monitor Flash player fullscreen hack

Wow, actually I thought I couldn’t top my five-noun post title “Live Ajax PHP regex tester, but now it happened. Looks a bit weird indeed.

But let’s get on topic: If you have two monitors connected to your PC, you will probably have a movie run on one of them sometimes while keeping on working on the other one. That does indeed work pretty well with video players. If you want to watch a Flash stream online though, you are facing a problem: You move the window over to the second screen, click “full screen” and delight – but as soon as you focus another window on your main monitor, the Flash movie on screen 2 will shrink back to its default size. Now, how stupid is that?

Update (16 December 2010)

Volker posted this FlashHacker in the comments, which can make the necessary changes automatically and also reverse them again if you wish. So if you don’t like the hexadecimal fiddling, this will make your life easier.

I found a solution in the video above:
Open the file C:\WINDOWS\system32\Macromed\Flash\NPSWF32.dll
or, on a 64 bit system, C:\Windows\sysWOW64\Macromed\Flash\NPSWF32.dll
in a hex editor like Hex-Editor MX.
Then look for your Flash version in the table below, navigate to the address given there, and change the value as stated.

In order to save the file, you have to close all browser windows. On Windows Vista/7, you will need to start the hex editor as administrator, so you can edit and save the .dll file. If you made any backup copies of the .dll before, be sure to move them out of the Flash directory, because otherwise some browsers will load the old version instead of the new, edited one.

    Mir scheint, als sei ein Hack mit der aktuellen Version 10,2,152,26 nicht mehr nötig.
