How to Change What Monitor a Game Is On

Getting a game to display on the monitor you actually want — not the one Windows or the game engine decided for you — is one of those tasks that sounds simple but has more moving parts than expected. The fix depends on whether you're dealing with a windowed game, a fullscreen title, a stubborn launcher, or a multi-monitor setup where Windows keeps defaulting to the wrong display.

Here's how each scenario works, and what's actually controlling where your game appears.

Why Games Don't Always Launch on the Right Monitor

When you run a game, it doesn't automatically "know" which monitor you prefer. It typically defers to one of three things:

• Windows' primary display setting — the monitor Windows treats as #1
• The game's own saved display preference — stored in a config file or in-game settings
• The last window position — relevant for windowed and borderless windowed modes

Fullscreen games usually lock to the primary monitor. Windowed games follow the last position of the window. Borderless windowed games often behave like windowed games but can be trickier to move because there's no visible title bar to grab.

Understanding which mode your game is running in is the first step to controlling which monitor it uses.

Method 1: Change Your Windows Primary Display

The most reliable way to control where fullscreen games launch is to set your target monitor as the primary display in Windows.

On Windows 10/11:

1. Right-click the desktop → Display settings
2. Click the monitor you want games to launch on
3. Scroll down to Multiple displays → check Make this my main display

This works because the majority of fullscreen games hardcode themselves to the primary display. Once you've switched, relaunch the game and it should appear on the correct screen.

The trade-off: your taskbar, desktop icons, and other apps will also shift to that monitor. For some setups that's fine; for others it disrupts the rest of the workflow.

Method 2: Move a Windowed Game to Another Monitor

If the game runs in windowed or borderless windowed mode, you have more flexibility:

• Drag the window — If there's a visible title bar, just click and drag the game window to the other monitor
• Windows keyboard shortcut — Press Win + Shift + Left/Right Arrow to snap the active window to another display instantly
• Right-click the taskbar icon — Some versions of Windows let you move a window via the taskbar context menu → Move

Once moved, many games will remember the position and relaunch on that monitor next time. Some don't — which brings up config files.

Method 3: Edit the Game's Config File

Many games save display preferences in a local config or .ini file. If a game keeps launching on the wrong monitor despite your preferences, editing this file directly often solves it. 🖥️

Common locations:

• DocumentsMy Games[GameName]
• %AppData%[GameName]
• The game's installation folder

Look for values like:

• MonitorIndex=0 (change to 1, 2, etc. — note that games often count from 0)
• FullscreenMonitor
• DisplayAdapter
• WindowPositionX / WindowPositionY

Set the coordinates to a position that falls within your target monitor's resolution space. For example, if your second monitor sits to the right of a 1920×1080 primary, an X value of 2000 would place the window on that second screen.

Method 4: Use In-Game Display Settings

Many modern games include a monitor selection option directly in their graphics or display settings menu. This is especially common in titles from the last five or six years.

Look for settings labeled:

• Display Monitor
• Target Display
• Screen
• Adapter

If it's there, this is the cleanest solution — no need to change your Windows primary display or edit config files. The game handles the preference itself and stores it independently.

Method 5: Launcher and Platform Considerations

Some launchers add another layer of complexity:

If a game is launching from a specific launcher and ignoring your preferences, check whether the launcher itself has display settings — some do.

Method 6: GPU Control Panel

Your graphics card's control panel (NVIDIA Control Panel or AMD Radeon Software) can sometimes influence display behavior for specific applications. You can set display preferences per-application, though this is more commonly used for resolution scaling and refresh rate than monitor selection specifically.

It's worth checking if other methods haven't worked, particularly for older games that don't have modern display settings menus.

The Variables That Determine Which Fix Works for You 🎮

Not every method works for every setup. What actually works depends on:

• Game mode — fullscreen, windowed, or borderless windowed
• How old the game is — older titles rarely have in-game monitor selectors
• Whether the game saves window position — some do, many don't
• Your monitor arrangement in Windows — which is set as primary, and how they're physically and logically arranged
• The game engine — Unity, Unreal, and older proprietary engines each handle multi-monitor setups differently
• Whether a launcher is involved — and whether it's overriding the game's own config

A newer AAA game with in-game display settings on a straightforward two-monitor setup resolves in under a minute. An older game running in forced fullscreen with no config options and a complex monitor arrangement takes more troubleshooting. The range between those two situations is wide.

Your specific combination of game, display setup, and OS configuration is ultimately what determines which of these methods — or which combination of them — actually moves the needle. ⚙️
