[Full Fix] Screen Resolution Changes on Its Own Windows 10

Why Does My Screen Resolution Keeps Changing by Itself

Screen resolution changes automatically often occur after waking from sleep, rebooting, or when using dual monitors/docks, as Windows misinterprets the display profile. It is primarily due to the following causes:

• Graphics driver issues: A corrupted or outdated driver can fail to maintain the correct display profile, causing Windows to fall back to default, often lower, resolutions.
• Startup programs/conflicting software: Certain apps in your startup menu might have forced resolution settings that trigger changes when launching.
• Failed monitor detection: When a monitor goes to sleep or is disconnected from a docking station, Windows may “forget” its native resolution, switching it to 1024×768.
• Incorrect scaling/high DPI: If scaling (e.g., 125% or 150%) is used, switching between monitors can trigger resolution issues.
• Game fullscreen optimizations: Some games override display settings.

Now, follow the methods below to stop screen resolution changes on its own.
