How to Move a Game to Another Monitor (And Make It Stay There)

Playing on a multi-monitor setup should feel seamless — but games have a habit of launching on the wrong screen, snapping back to your primary display, or refusing to move at all. Here's what's actually happening and how to work around it.

Why Games Default to One Monitor

Most games launch on whatever Windows (or macOS) has designated as the primary display. This is a system-level setting, not a game preference. The primary monitor is where new windows and fullscreen applications open by default, which is why your game keeps appearing on the same screen even after you've moved it manually.

Fullscreen mode makes this worse. Unlike a browser window, a game running in true fullscreen mode is rendered directly to a specific display adapter output. It doesn't behave like a movable window — it's locked to whichever monitor the system assigns it.

The Fastest Methods for Moving a Running Game

1. Switch to Windowed or Borderless Windowed Mode First

This is the most reliable starting point. Inside the game's video or display settings, switch from Fullscreen to either:

• Windowed — has a visible title bar; you can drag it
• Borderless Windowed (also called Fullscreen Windowed) — looks fullscreen but behaves like a window

Once you're in windowed mode, you can drag the game to the second monitor, then optionally switch back to fullscreen — and many games will remember that display position.

2. Use the Windows Keyboard Shortcut

With the game window active (click it first), press:

Windows + Shift + Arrow Key (Left or Right)

This snaps the active window to the monitor in that direction. It works reliably in windowed and borderless modes. It does not work on true fullscreen applications.

3. Change Your Primary Display in Windows Settings

If you want a game to always open on a specific monitor, you can reassign which display Windows treats as primary:

1. Right-click the desktop → Display settings
2. Select the monitor you want games to open on
3. Scroll down to Make this my main display

Every new app, including games, will now launch there by default. The trade-off is that your taskbar, system tray, and desktop icons move with the primary display — which affects your whole workflow, not just gaming.

Game-Specific and Platform-Level Settings

In-Game Display Selection

Many modern games include a display selection dropdown directly in their video settings. Look for options labeled Monitor, Display, or Screen — usually numbered (Display 1, Display 2) or named by resolution. Changing this setting is the cleanest fix because the game stores it in its own config file.

Steam and Other Launchers

Steam itself doesn't control which monitor a game launches on, but some games launched through Steam respect a launch options parameter. For games that support it, you can sometimes pass a display index through the launch options field in Steam (right-click game → Properties → Launch Options), though this is game-dependent and not universal.

Config File Editing

For games that don't expose monitor settings in the UI, the preference is often buried in a config or .ini file. Search for terms like monitor, display, screen_index, or adapter inside the game's settings files. Changing these values manually works for many PC titles, though the exact syntax varies by engine.

Why the Game Keeps Snapping Back 🖥️

A few common causes:

If a game consistently reverts, borderless windowed mode is usually the most stable long-term fix, since the OS treats it as a normal window and respects its position across sessions.

macOS Considerations

On macOS, moving a game to a second monitor follows similar logic — fullscreen apps occupy their own Space and don't move freely between displays. Switching to windowed mode, then dragging, then optionally re-entering fullscreen on the target monitor is the standard approach. macOS also has a setting under System Settings → Displays that controls which display is primary (drag the white menu bar indicator to your preferred screen).

Variables That Affect Your Outcome 🎮

How smoothly this works depends on several factors specific to your setup:

• Game engine — Unreal, Unity, and proprietary engines all handle multi-monitor behavior differently
• Number and arrangement of monitors — identical resolutions and refresh rates across displays cause fewer conflicts
• GPU driver version — outdated drivers occasionally introduce multi-monitor quirks
• Whether monitors are the same or different refresh rates — mixed refresh rate setups can cause games to default unexpectedly
• Whether you're using display cloning vs. extended mode — extended mode is required; cloning treats both monitors as one

A setup with two identical 1080p 144Hz monitors connected to a mid-range or higher discrete GPU will generally have the fewest issues. Mixed configurations — say, a 4K primary and a 1080p secondary, or integrated + discrete GPU outputs — introduce more variables and sometimes require per-game workarounds.

Where you land on that spectrum shapes which of these methods will actually stick for your situation.
