How to switch screens in an esports setup

You switch displays before a match, but the game opens on the wrong monitor, the picture appears on both screens, or the image looks different from one panel to another. These problems can come from display mode, the monitor a game selects, or the operating system's screen arrangement.

First check which displays your computer and browser can see. Then set the display mode and main screen in your system or game. The Screens tool can show each connected display's resolution and scale, and run a color test on a screen you choose.

Check which screens are connected

Open the Screens tool and review the listed displays, including their resolution and scale.
If there is more than one display, choose each one for its color test. Look at the physical monitors to see which panel is showing the test.
Compare the list with your desk. Note which screen is your gaming monitor and which is a laptop display, TV, or second monitor.
Open your operating system's display settings and check whether the screens are set to extend, duplicate, or use only one display.

The tool checks what the browser can access. It does not switch displays or change your game settings. If the screens are hard to tell apart, the color test helps you match a listed display to the monitor in front of you.

What the result means

The game opens on the wrong monitor

Your system may have a different display set as the main screen, or the game may remember a display from an earlier session. Some games open full-screen on the main display, while others have their own display choice. Set the gaming monitor as the main display before launching the game, then check the game's video or display options.

The same picture appears on both monitors

The displays are probably set to duplicate, also called mirror mode. This can be useful for showing the same content on a TV, but it does not give you a separate desktop on each screen. Switch to an extended desktop if you want the game on one monitor and other windows on another.

The game appears on one screen, but the desktop is on another

This is normal when the displays are extended. A full-screen game may take over the display it selected, while the desktop remains available on the other screen. If the game is windowed, you may be able to move it to the gaming monitor before switching to full-screen mode.

The screens have different sizes or scales

Different resolution and scale values are common, especially when a laptop is connected to an external monitor. They describe how much desktop space and how large interface elements appear. They do not tell you the monitor's refresh rate or prove that the game is running at its intended frame rate.

A screen is missing from the tool or system settings

The display may not be connected, powered on, or detected by the computer. A browser can only report screens the system makes available to it. Check the cable and system display settings before treating this as a browser problem.

How to fix screen switching

Choose the right display inside the game. If the game has a monitor or display selector in its video settings, choose the esports monitor and apply the change. The option's name and location vary by game.
Set the gaming monitor as the main display. On Windows 11, open Settings › System › Display, select the gaming monitor, and turn on Make this my main display if that option appears. On macOS, open System Settings › Displays, select the monitor, and set Use as to Main Display if available.
Choose extend instead of duplicate. In Windows 11, go to Settings › System › Display and select Extend these displays in the multiple-display options. On macOS, open System Settings › Displays and set the second screen to Extended Display rather than mirroring, if that choice is shown.
Move the game before making it full-screen. If the game opens as a window, drag it to the gaming monitor, then switch to full-screen mode. Some games keep using the monitor selected when they first launch, so close and reopen the game after changing the main display.
Check resolution and refresh rate separately. In Windows 11, open Settings › System › Display › Advanced display, select the gaming monitor, and choose a refresh rate it supports. On macOS, go to System Settings › Displays and check the available resolution and refresh-rate choices for the selected screen.
Use the system's display switch shortcut when needed. In Windows, press Windows + P to open the projection choices, then choose an option such as extend or second screen only. This is an operating-system shortcut, not a browser control. On a Mac, use System Settings › Displays to change how the screens are used.

Why display switching can feel different in a game

Changing the main display, moving a game window, and changing the display mode are separate actions. The main display is where the system places many new windows. Moving a window changes where that window appears. Extending or duplicating changes whether the monitors show separate or shared desktop content. A game can also store its own monitor choice.

Refresh rate is another separate setting. The Screens tool reports resolution and scale, but it cannot confirm that your monitor is running at 144 Hz, 240 Hz, or another rate. Check the operating system and the game's video settings, and choose only a refresh rate the display supports. After changing these settings, reopen the game and confirm the image appears on the intended monitor.
