BF4 keeps switching to window mode

[TheShackler]

During gameplay, my game keeps switching to window mode at random. Started happening after the last update. Some have suggested to quit Samsung Magician, this did not resolve the issue. Any ideas?

Make sure that Origin in game is disabled since if someone messages you your game will go into windowed mode sometimes. I have also found this happens when someone text messages me when I am using Teamspeak3.

To turn off Origin in game log into Origin, in the upper left hand corner click on the word "Origin" in the menu, and then click on "Application Settings". Next go to the "Origin in game" tab and uncheck the "enable Origin in game" box.

Thanks for the reply, I will try but I don't use teamspeak or have anyone that messages me.

Instead of Fullscreen try Borderless if OiG doesn't take care of it.  (Not a fan of OiG even when it works personally)

None of this worked, the game is now unplayable. Bummer, I built out my dream system to play this game I don't really play any others. Not sure what else to try. This is a sad day.

Hello TheShackler,

A few games have trouble running in fullscreen due to graphics card drivers. What graphics card do you use with what driver installed?

I had this issue too, I turned the PC and monitor off, unplugged and reinserted the HDMI plug on both sides at least once, and turned the monitor on. Then the PC, and it was fixed.

The communication between the monitor and PC was disrupted a tiny bit but just enough to make this happen.
