A computer producing an unexpected output — wrong print, wrong display resolution, wrong calculation — usually traces to an application or driver setting, not the hardware. For Windows graphics driver, first test one display directly, inspect Device Manager and compare basic versus vendor driver behavior.
What this covers
- Windows graphics driver with this exact failure state
- Diagnosis across display/cable versus GPU, driver version, app and power state

0 of 4 completedCapture the exact failure state
ReversibleRecord the exact setting, profile or version active in the application producing the wrong result. Expected behavior: render the desktop and applications at stable supported resolutions and acceleration.
Isolate the component boundary
ReversibleTest one display directly, inspect Device Manager and compare basic versus vendor driver behavior. Reproduce the same input in a different application or user profile to see whether the fault follows the app or the system. Boundary to separate: display/cable versus GPU, driver version, app and power state.
Correct only the proven cause
ReversibleInstall the OEM/vendor-supported driver or roll back the one proven to fail. Correct the setting, color/display profile or driver version proven by the comparison.
Verify and stop safely
ReversibleRepeat the original task and confirm the correct output with the fix applied. Stop for artifacts before Windows, overheating, burning odor or repeated black screens.
