DNXFullScreens

Multi-Monitor Borderless Fullscreen

Extend any Windows application across multiple monitors seamlessly.

DNXFullScreens removes window borders and stretches applications across your selected monitors with pixel-perfect precision. Originally created to run Chrome Remote Desktop across dual screens with a single instance, it has evolved into a general-purpose solution for any Windows application.

Why DNXFullScreens?

Many applications lack native multi-monitor support or restrict borderless fullscreen to a single display. DNXFullScreens fills this gap by:

Key Features

Multi-Monitor Support

Select any combination of monitors to span your application. Works with 2, 3, or more displays in any physical arrangement.

Visual Edge Adjustment

Fine-tune window edges with an intuitive visual overlay. Adjust each corner independently to account for monitor bezels or alignment preferences.

Global Hotkeys

Control everything without leaving your application. Default hotkeys (customizable):

Application Profiles

Adjustments are automatically saved per application. Launch your favorite programs and activate fullscreen - your custom settings are instantly applied.

Always-On-Top Mode

Keep your application above all other windows, perfect for monitoring tools or reference material. Works independently of fullscreen mode.

Visual Adjustment Mode

The visual adjustment interface provides real-time feedback while you fine-tune window edges:
