Final answer:
In Safe Mode, Windows defaults to a lower screen resolution of 800 x 600 to ensure compatibility and reduce the drivers and processes needed.
Step-by-step explanation:
When Windows is started in Safe Mode, it uses a lower screen resolution than the user might typically have set under normal operating conditions. This lower resolution is used to ensure maximum compatibility with all types of hardware and to minimize the number of drivers and processes required for Windows to run. In this case, the correct resolution that Windows typically uses in Safe Mode is 800 × 600.
