How to Fix a Steam Game Opening on the Wrong Monitor

Having more than one monitor can be a big help, whether you're gaming, streaming, or just keeping Discord and guides open on a second screen. But one of the most annoying things that can happen is when you start a Steam game and it shows up on the wrong screen. It's annoying, especially in fullscreen games where it's not as easy to switch displays as it is to drag a window. Fortunately, this problem is easy to fix once you know where to look.

We'll show you how to get your games to launch on the right screen in this guide. We'll use both system and in-game settings. And if you're waiting for your next download or in between matches, now might be a good time to practice your aim somewhere else. You don't even need a second monitor to play games with case battles, skin upgrades, and skill-based challenges that are fun and keep you sharp.

Quick Fixes (Summary for Fast Solutions)

If your Steam game keeps opening on the wrong screen, try these quick fixes to get it to the right one without having to go through a lot of complicated settings:

Set Your Main Display in Windows Settings
Right-click your desktop, go to Display Settings, and set the preferred monitor as your primary display. Most games default to launching on the primary screen.

Use Windowed Mode and Drag It Over
Launch the game in windowed or borderless windowed mode. Once it opens, drag it to the correct monitor and then switch back to fullscreen if needed—many games remember this setting.

Add Launch Parameters in Steam
Right-click the game in your Steam library > Properties > Launch Options, and try adding -monitor 1 (or 2, depending on your setup). This can force the game to open on a specific screen.

Check GPU Control Panel Settings
For NVIDIA or AMD users, make sure scaling and display settings are properly configured. Sometimes GPU-level overrides can affect how games choose monitors.

Why Steam Games Open on the Wrong Monitor

It's not usually a bug if your Steam games open on the wrong screen. It's just how your system remembers or prioritizes displays. There are a number of settings in your OS, GPU, or game files that can affect where games show up.

Game Remembering Last Monitor

A lot of games keep track of the last monitor you used in their configuration files. If you played on your second display before, even just once, the game might keep starting there until you move it back and exit the right way.

Steam Launch Behavior

Steam doesn't directly control how monitors behave. It starts games on whatever Windows calls the main display, unless the game or system remembers a different setting from when it was last used.

Display Configuration Conflicts

If you change how your monitors are set up (for example, by plugging in a new screen, using a projector, or switching between docked and undocked laptop mode), problems can happen. If the resolutions, refresh rates, or GPU scaling are not set up right, the game might not know where to launch, which could cause it to open on the "wrong" monitor.

Method 1: Use Windows Display Settings

One of the easiest ways to fix Steam games that start on the wrong screen is to change your display settings in Windows. These settings tell your computer which monitor to use as the default for starting programs, including games.

Set the Primary Monitor

To guide Steam and your games to launch on the correct screen:

• Right-click anywhere on the desktop and choose Display settings
• Click the monitor you want to use for gaming
• Scroll down and check Make this my main display
• Close the settings window and relaunch your game

This makes sure that Windows sees your favorite monitor as the main one, so most games (especially those that open in full screen) will open there by default.

Reposition Game in Windowed Mode

Try this quick trick if changing the main display doesn't work or you don't want to move things around on your desktop:

• Launch the game in Windowed or Borderless Windowed mode
• Drag the game window to your desired screen
• Exit the game while it's on that screen

Most games will remember where you last closed them and open up on that screen the next time. You can switch back to Fullscreen mode after that if you want better performance or immersion.

Method 2: Force Monitor via Launch Options

If changing the display settings doesn't fix the problem, you can tell Steam to start games on a certain monitor instead. This method adds command-line parameters to the game's launch options. This is useful for games that support them.

Adding Monitor Launch Parameters

Some games let players choose which GPU adapter or monitor to use when they start the game by using custom options. This is how to do it:

1. Open Steam and right-click the game in your library
2. Select Properties
3. Under the General tab, locate Launch Options
4. Add a command like: -monitor 2 or -adapter 1

This tells the game which monitor index to use. But remember that not all games support these commands, and the index number may be different depending on how your system is set up. You might have to try different values to find the right one.

Using Steam Big Picture Mode Settings

You can also set display preferences directly in Big Picture Mode, which is Steam's controller-friendly interface for launching games.

• Launch Big Picture Mode from Steam
• Go to Settings → Display
• Choose the monitor you want Steam (and games) to use

Big Picture Mode can sometimes change system settings, especially for full-screen games. This is a good way to get around problems when normal display changes don't work.

Method 3: Adjust In-Game Settings

Sometimes, the best way to fix something is to do it in the game itself. You can choose which monitor to use in a lot of games, especially when you switch between fullscreen and windowed modes. If the game doesn't start where you think it should, it could be because of its own resolution or display mode settings.

Game Resolution and Display Mode

To begin, make sure that the game's resolution is the same as the monitor's native resolution. If the settings don't match, the display system might get confused and show the game on a second screen. Go to the game’s video or graphics settings and:

• Set the resolution to your preferred monitor's native size (e.g., 1920x1080)
• Double-check any display monitor selector (if available) and assign it correctly
• Apply and save the changes, then restart the game to see if it launches on the correct monitor

Borderless Window vs Fullscreen

Changing between Fullscreen, Windowed, and Borderless Windowed modes can have a big effect on which monitor the game uses. In general:

Borderless Windowed mode tends to align with your Windows primary monitor settings.

Exclusive Fullscreen mode may override Windows preferences and default to a monitor based on last use or system priority.

If your game supports it, use Borderless mode as a middle ground. It acts like fullscreen but respects monitor assignments at the OS level and makes alt-tabbing easier.

Method 4: Use GPU Control Panels

Your GPU's control panel might be the answer if changing Windows or in-game settings hasn't worked. Graphics drivers often decide which monitors to use first and how to scale them, so using NVIDIA or AMD settings can help make sure the right screen is used to start games.

NVIDIA Display Settings

For NVIDIA users, here’s how to ensure your primary monitor is recognized:

1. Open NVIDIA Control Panel
2. Go to Display > Set up multiple displays
3. Make sure the correct monitor is checked and marked as primary
4. Navigate to Adjust desktop size and position
5. Under Scaling, select Full-screen
6. For Perform scaling on, choose GPU, then apply your changes

These steps help make sure that the desired resolution and assignment are followed at the hardware level, which Steam and games usually do by default.

AMD Eyefinity / Display Config

If you're using an AMD GPU:

1. Launch AMD Radeon Software
2. Go to the Display tab
3. Enable GPU Scaling
4. Set the Scaling Mode to Full Panel
5. Double-check that your preferred gaming monitor is marked as primary in Windows

AMD's scaling tools are great for making sure that games look good on all screens, especially when you switch between fullscreen and windowed modes.

By using your GPU settings, you can make sure that display preferences are enforced at the system level. This lowers the chance that games will start on the wrong screen. Are you ready for the next part?

Persistent Problems? Try These

Don't worry if your game keeps opening on the wrong monitor even after you've changed all the usual settings. There are still a few more advanced fixes you can try. These methods focus on fixing config bugs that keep coming back, problems with display detection, and conflicts with window management that sometimes go unnoticed.

Reset Game Config Files

Some games keep track of your monitor preferences in their configuration files, even if you change the settings on your computer.

To reset this:

• Locate the game’s config folder (usually in Documents, AppData, or the game install directory)
• Find files like settings.cfg, user.config, or video.txt
• Delete or move them to a backup folder
• Restart the game to generate fresh default settings

This can fix problems with launching that are caused by old screen assignments.

Check for Dual Monitor Bugs

Some games, especially older or less optimized ones, still use old display indexing. If the second monitor on your system is messing with the game's logic, try this:

1. Unplug the second monitor
2. Launch the game (it should default to the only connected screen)
3. Plug your second monitor back in after the game has started

It's a simple trick, but it works surprisingly well for fullscreen games that won't close.

Use Third-Party Monitor Tools

With advanced tools like DisplayFusion or Actual Multiple Monitors, you can set rules for where apps open, even games. You can use these programs to set the position of windows or assign apps to certain displays when they start up.

⚠️ Caution: If you're playing competitive games like CS2, don't use any overlays or processes that might mess up the anti-cheat systems. Before using any third-party tools, make sure they work with your system.

These tools can make your experience better overall, as long as you use them safely. This is true if you like to do more than one thing at once or switch between games and browser tabs (or Clash.gg case battles).

Final Thoughts

If you launch a game on the wrong monitor, it can break immersion before the match even starts. But now you have the tools to fix it quickly and reliably. A few smart changes can help keep your gaming smooth and free of problems, whether you're switching between setups or fine-tuning your display settings.

And if you want to take a quick break between rounds of trial and error, there are lots of ways to keep the fun going. Platforms like Clash.gg offer short gaming experiences like skin upgrades, fast-paced case battles, and community challenges, which are great for cooling off before getting back into your main setup.

Frequently Asked Questions

How do I force a game to open on my second monitor?

If you want to use Monitor 2 as your main display in Windows, you can also start the game in Windowed mode, move it to the second screen, and then close it. The game usually remembers this spot the next time you start it up.

Can I set Steam to always use a specific monitor?

Steam doesn't let you choose which monitor to use, but most games will use the main display in Windows. To make sure your game works well on more than one screen without having to change the launch settings every time, use borderless windowed mode.

Why do my settings keep resetting?

Your game might be storing information about where the screen is in a config file. The game will go to that file if it points to an old monitor ID. Deleting or resetting the config often fixes problems with monitors that keep happening.

What if only one game has the problem?

The problem could be with the settings for that game. In the folder, look for a video.txt or config file. You can also use command-line launch options like -monitor to make that title show up on a different screen.
