Core Features of the Desktop Casting Window (Split Screen · Full Screen · Pause · Hide Title Bar)

he 1001 TVs desktop app allows you to control screen casting directly from the casting window, including full-screen display, pause, hiding the title bar, and multi-device split-screen casting. These actions can be performed without using a phone or other sending devices, helping optimize large-screen viewing and supporting both collaborative and individual use cases.

1. How to Use

1.1 Title Bar Controls

The title bar provides quick access to the following features:

Automatic Split Screen (Windows)

After a successful connection, click the four-square icon in the title bar to automatically split the screen into four sections.
Each device is displayed in its own window, supporting both portrait and landscape orientations—ideal for multi-device comparison or team collaboration.

Full Screen Display

You can enter full-screen mode in three ways:

· Click the Full Screen icon in the title bar

· Open Settings and select Full Screen from the menu

· Double-click the center of the casting window
(Available when Settings > Display > Casting Window > Auto Arrange Multiple Windows is turned off)

In full-screen mode, a minimize icon appears in the top-right corner and automatically hides after 5 seconds. Move the mouse to the top-right corner to show it again.
Press ESC to exit full-screen mode at any time.

Other Quick Controls

The title bar also includes shortcuts for Mute, Pause, Settings, Minimize, and Full Screen, allowing you to perform common actions with a single click.

1.2 Right-Click Menu Controls

Right-click on any blank area of the casting window to access additional options:

Screen Rotation

Select Rotate Left or Rotate Right (90° per rotation).
This is especially useful when mirroring a portrait-mode phone to a landscape computer screen.

Pause / Resume Casting

Click Pause to freeze the current screen.
Click Resume to continue real-time casting.

Hide Title Bar

Select Hide Title Bar (F10) to remove the title bar and maximize display space.
You can restore the title bar via the right-click menu or by pressing F10 again.
