Borderless Fullscreen Keys

Make a windowed game borderless fullscreen with one key on your Stream Deck. On a Windows PC, a press removes the title bar and frame of the active window and stretches it over the screen: windowed game full screen, or a borderless window of a fixed size. Press again to put the window back as it was.

Features

Borderless Fullscreen: the active window fills its screen, or a screen you choose, over the taskbar or up to it

Borderless Window: frame off, at the same size or at an exact size such as 1920 x 1080

Restore Windows: puts back every changed window; the key shows how many

The key shows the window name and FULL or WINDOWED

English and Japanese

Safety

Frame, position and size are saved before a change

When Stream Deck closes, changed windows are put back first

If the plugin is killed, Restore Windows puts them back after a restart

Left as they are: the desktop, the taskbar, the Stream Deck app, minimized windows

Requirements and limits

Windows 10+, Stream Deck 6.9+. Tested on Windows 11 with one screen

Some programs draw their own frame or keep a fixed size; a change the window rejects is undone

Borderless windowed mode, not exclusive full screen

No claim about anti-cheat software

Privacy

Reads the title and size of the active window to show them on the key. Nothing is sent anywhere.
