How to Change Monitor 1 and 2 in Windows 11

With two monitors on Windows 11, you might want the screen on your left to be “1,” the taskbar and new windows to appear on the other screen, or your mouse to move naturally between displays. Windows handles each of these with a different setting. Here’s what you can change, what you can’t, and how to get the setup you want.

First, Understand Monitor Numbers

Windows assigns numbers to monitors based on how your graphics hardware detects them, usually by which port each display is plugged into. There’s no setting to simply rename monitor 2 as monitor 1. What most people actually want is one of these:

• Change the main display, so the taskbar’s clock, notifications, and most new windows appear on a different screen.
• Rearrange the displays, so moving your mouse off the right edge of one screen lands on the correct side of the other.
• Change which screen gets number 1, which requires swapping cables.

How to Identify Your Monitors

1. Right-click the desktop and choose Display settings (or go to Settings > System > Display).
2. Click Identify. A large number appears on each screen for a few seconds.

How to Change Your Main Display

1. In Display settings, click the monitor box you want as your main screen.
2. Scroll down and expand Multiple displays.
3. Check Make this my main display.

The taskbar’s system tray, notifications, and many apps now default to that screen. The monitor number stays the same, but it now behaves as your primary display.

How to Rearrange Your Monitors

If your mouse jumps the wrong way between screens, the layout in Windows doesn’t match your desk.

1. In Display settings, click Identify to see which box is which.
2. Drag the monitor boxes so they match the physical position of your screens, left to right (or one above the other).
3. Line up the tops or bottoms of the boxes to match how the screens actually sit.
4. Click Apply.

How to Swap Which Monitor Is Numbered 1

To change the numbers themselves, change how the monitors are connected:

1. Shut down your computer.
2. Swap the cables between the two video ports on your graphics card or laptop.
3. Turn the PC back on and check Identify again.

Your graphics driver’s control panel (NVIDIA Control Panel, AMD Software, or Intel Graphics settings) may also show displays in a different order, but numbering in Windows Settings generally follows detection order.

Quick Display Shortcuts

• Windows + P: Choose PC screen only, Duplicate, Extend, or Second screen only.
• Windows + Shift + Left/Right Arrow: Move the active window to the other monitor.

Other Multi-Monitor Settings to Check

• Taskbar on all displays: In Settings > Personalization > Taskbar > Taskbar behaviors, turn on Show my taskbar on all displays.
• Remember window locations: In Multiple displays, check Remember window locations based on monitor connection so windows return to the right screen.
• Scale and resolution: Select each monitor and set its Scale and Display resolution individually.

Troubleshooting

• Second monitor not detected: In Display settings, expand Multiple displays and click Detect. Check cables and the monitor’s input source.
• Settings revert after restart: Update your graphics driver.
• Layout changes when docking a laptop: Windows remembers layouts per dock configuration; set it again while docked.

Frequently Asked Questions

Does the main display have to be monitor 1?

No. Any monitor can be your main display regardless of its number. Many people with a laptop and an external monitor make the external screen the main display while it stays numbered 2.

Why does my mouse get stuck at the edge of a screen?

The monitor boxes in Display settings probably don’t line up the way your screens do. Drag them so their edges overlap where you want the mouse to cross.

Can I set different refresh rates on each monitor?

Yes. Select a monitor in Display settings, open Advanced display, and choose a refresh rate for that screen.

Will these steps work on Windows 10?

Yes, the options are almost the same. On Windows 10, the main display checkbox appears directly under Multiple displays in Settings > System > Display.

Summary

In Windows 11, you can’t directly renumber monitors 1 and 2, but you can make any monitor your main display in Settings > System > Display > Multiple displays > Make this my main display, and drag the monitor boxes to match your desk. To change the numbers themselves, swap the video cables between ports.
