When applying the fullscreen setting, the game does not go fullscreen. It will go to the specified resolution, but won't be fullscreen; it'll still be a window. I can change back to windowed mode and that works as a window, but fullscreen is not working after the latest patch.

How can I make this game fullscreen?

It turns out having TeamViewer enabled would cause this. Killing the TeamViewer process resolved this issue.

  • T.V. installs its own generic video driver to be ran over your normal one in place. I had a similar issue, removing TV resolved it.

For most Windows applications, you can change to fullscreen by pressing Alt-Enter. However, I only assume that this works for Battlefield 3.

  • This does the same thing as applying the fullscreen option in the Options menu. The issue still happens either way.

If you want to play BF3 windowed fullscreen you need to download a program called ShiftWindow, it makes the game/application fullcsreen but has the same actions as a windowed fullscreen.

  • League? This is about BF3.

  • No, the same does not apply - BF3 supports full-screen. Commented Apr 2, 2012 at 19:45
