The VideoLAN Forums

With VLC .99 the video plays ok on my laptop screen but I have a 2nd monitor attached and only the VLC player frame shows with no video inside it on the larger monitor. The same videos (mpg or wmv) will play with Windows media player on both screens.

The release notes for 0.9.9 say "Correct Fullscreen behaviour on Multi-Screen setups on Windows", so clearly something changed... however contrary to what the notes say it seems to now be broken.

My guess in your situation would be to try different video output settings and make sure your video driver is setup properly... but there may be work around.

In my case, 0.8.6 had no problem remembering to show my video full screen on my second monitor (TV), however 0.9.9 will not let me set the default device to the 2nd monitor, nor remember my settings from last session. When I open a new video, even when I don't close the app, it displays it on the laptop screen rather than on the 2nd monitor. Actually is also shows full screen on the 2nd monitor but scaled incorrectly (16:9 being squished to something else). I have to manually move the display window from the laptop screen to the 2nd monitor and then switch toggle it to full screen every time I start a video for it to display properly.

My Setup:
Hardware: Acer 5672 laptop running XP Pro has a ATI X1400 video card which is connected to a 720P television via DVI.
VLC Settings are basically default however I change the following:
Interface: Uncheck "Integrate Video in Interface", Uncheck "Show a controller in fullscreen"
Audio: Check "Use S/PDIF when available", Output/Type "Win32 waveOut extension output"
Video (eveything left at default):
Uncheck "fullscreen", uncheck "always on top", check "skip frames",
Check "accelerated video output", check "windows deco..", check "use hardware YUV-RGB"
Output "Default" which is end up being DirectX
Uncheck "Enable wallpaper mode", Display device "Default" (which is the only option.
