how do i stop windows 10 from changing resolution? – Explore all details

Windows 10, Microsoft’s flagship operating system, offers a robust and dynamic user interface, designed to adapt to the various requirements of different devices and displays. One of these adaptability features is the automatic adjustment of screen resolution. However, for some users, this automated adjustment can be an inconvenience, especially when it frequently changes due to specific software or system updates. This article will provide a step-by-step guide on how to stop Windows 10 from automatically changing screen resolution.

Understanding Screen Resolution

What is Screen Resolution?

Before diving into the process, it’s crucial to understand the concept of screen resolution. Simply put, screen resolution refers to the number of pixels displayed on your screen horizontally and vertically. A high-resolution display will provide more detail and sharper images. When Windows 10 automatically adjusts the resolution, it is trying to optimize the display according to the content shown and the display capabilities.

Why Does Windows 10 Change Screen Resolution?

There are several reasons why Windows 10 might be changing your screen resolution. It could be due to a recently installed application or an update that modifies system settings. Graphics driver updates can also cause changes to screen resolution. Furthermore, plugging in a new monitor or adjusting your display settings manually can prompt Windows 10 to alter the resolution.

Step-By-Step Guide to Stop Windows 10 from Changing Resolution

Check Your Display Settings

To begin, access your display settings by right-clicking on the desktop and selecting “Display settings” from the dropdown menu. Under the “Scale and layout” section, check the current resolution. If it’s not the preferred one, select the desired resolution from the drop-down menu.

Update Your Graphics Driver

Outdated graphics drivers can cause Windows to automatically change the screen resolution. To check for any updates, go to the “Device Manager” (you can search for it in the Start menu). Expand “Display adapters,” right-click your graphics card, and select “Update driver.” Follow the prompts to search for updates.

Disable Display Adapter Settings in Registry

If the issue persists, it might be due to certain automatic display settings embedded in the Windows Registry. Here’s how you can disable them:

  1. Press Win + R to open the Run dialog box.
  2. Type regedit and hit enter to open the Registry Editor.
  3. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration.
  4. For each sub-key in the Configuration key, find the setting named PrimSurfSize.cx and PrimSurfSize.cy. Double click on each and change the ‘Value data’ to the horizontal and vertical pixel counts of your desired resolution.
  5. Restart your computer to apply the changes.

Important: Always exercise caution when modifying the Registry Editor, as incorrect changes can potentially harm your system.


While Windows 10’s automatic resolution adjustment is meant to optimize the user experience, it may not be ideal for all users or circumstances. The steps outlined in this guide should assist you in preventing these automatic changes and maintaining your preferred screen resolution. Remember, maintaining up-to-date system and driver updates can prevent many such issues, leading to a smoother and more enjoyable Windows 10 experience.
