For a list of games, see games with borderless fullscreen windowed support.

Key points

Borderless fullscreen windowed offers similar benefits as normal windowed mode, but with a fullscreen-like appearance.
Native feature in many modern titles, and can often be forced in the majority of older titles.
Can sometimes be used to enable wider or higher resolutions via resizing the game's viewport.[1][2]
Seamless task switching with no risk of crashes or freezes with a minor loss in performance.
Eliminates screen tearing on Windows (only on Vista and later) due to Vertical sync (Vsync) being applied for all windows by the Desktop Window Manager (DWM)..[3]
..but will subsequently cause additional input lag as well, due to the aforementioned vertical sync. It is possible to disable the vertical sync, however it requires either disabling DWM (only possible on Vista/7) or by using a certain presentation mode and flag.[4]

Borderless fullscreen windowed refers to a mode where the game presents the rendered image in a maximized window without borders making it cover the whole monitor. This is opposed to a regular window that uses window decorations around the contents of the window, or fullscreen exclusive mode where the game takes control over the output device and where each application switch required a display mode switch to occur.

This feature is known by a lot of different names between games, such as borderless mode, maximized window, fullscreen window, or any combination thereof. Some titles might also refer to it using less common names, such as scaling or even fullscreen if the game does not support exclusive fullscreen mode.

Multiple monitors script

Someone needs to check whenever this explanation for the script is correct or if 0, 0, and A_ScreenWidth/Height mean that the script automatically detects the user's resolution.
This is a snippet from the Fullscreen toggle script.
Fullscreen script
  • The values 0, 0, represent the coordinates of the upper left corner of the window.
WinMove, ahk_id %WindowID%, , 0, 0, A_ScreenWidth, A_ScreenHeight
  • For multiple resolutions the values have to be the sum of the monitors total width, for 3840x1080 them being.
WinMove, ahk_id %WindowID%, , 1920, 0, 1920, 1080


Use 1920, 0, 1920, 1080 (right) or 0, 1920, 1920, 1080 (left) in order to change which side of the screen is filled.


Most Linux window managers allow fullscreen applications to natively run under a borderless mode by default.


  1. In the settings under:
    Devices > Keyboard > Windows 
    Set a hotkey for "Toggle fullscreen mode". e.g. Ctrl+Alt+Home
  2. Start the game in windowed mode.
  3. Move it to your preferred monitor.
  4. Select the game and enter the hotkey. e.g. Ctrl+Alt+Home


  1. Start the game in a windowed mode.
  2. Move it to a new virtual desktop by using Shift+ Win+Number.
  3. Switch to the virtual terminal with Win+Number then go into fullscreen mode by pushing Win+F.

Another tip that exclusively works on Linux is running your game in a separate X server instance. This allows you to switch between your game and your desktop using Ctrl+Alt+F7 and Ctrl+Alt+F8 (buttons may differ, may be F1 through F12) and it increases performance and stability. To do this, edit the launch options for your game on Steam as follows:

Run Game in New X Server
xinit %command% :1


Manually launch a Non-Steam game by replacing %command% with the path to the game executable. Some games, including Middle-earth: Shadow of Mordor may run into glitches using this method (as verified by Feral Interactive)



  1. See Command line arguments.
  2. Use the -windowed -noborder arguments.


  1. Use the -popupwindow command line argument.
  2. Launch the game in windowed mode (if no option is available toggle with Alt+ Enter).

Windows troubleshooting

Game crashes on startup

Certain borderless applications have to be started before the game itself and not while the game is running.

Window constantly resizes itself

After applying the borderless mode simply restart the game itself, while keeping the borderless application open.
