Hello! My name is Mostafa, and I will try my best to assist you with this so that you find a satisfactory solution.
To make three external displays line up for cursor movement, it's better you have three monitors with the same size and resolution, but you can try to configure the display settings by the following steps:
- Right-click on the desktop and select "Display settings" from the context menu. This will open the display settings window.
- In the display settings window, you should see all connected displays labelled as "1," "2," "3," etc. Identify each display by its number.
- Drag and arrange the display icons in the display settings window to match the physical arrangement of your monitors. Click and drag the display icons to the desired positions to align them correctly. Ensure that the monitors are placed in the correct order.
- Once you have arranged the displays, click on each display icon and scroll down to the "Multiple displays" section. Choose the option "Extend desktop to this display" for each monitor to have a separate workspace on each screen.
- Check the resolution settings for each display. Make sure that the resolution settings are set correctly for each monitor to match their native resolutions. You can adjust the resolution under the "Resolution" drop-down menu for each display.
- Finally, click on "Apply" to save the changes and confirm the display configuration. Windows will adjust the settings and apply the changes.
You can try to turn on or off “Ease cursor movement between displays” in Settings.
- Open Display settings ms-settings:display
- Click/tap on Multiple displays to expand it open.
- Turn on (default) or off Ease cursor movement between displays for what you want.
