How to Change a Screensaver on Windows, Mac, and Other Devices

Screensavers were originally designed to prevent phosphor burn-in on older CRT monitors — a real hardware problem where static images would permanently etch themselves into the screen. Modern displays don't have that vulnerability, but screensavers have stuck around as a way to add personality, display useful information, or signal that a computer is idle. Changing yours is straightforward once you know where to look — and the exact path depends heavily on your operating system.

What a Screensaver Actually Does Today

On contemporary LCD, OLED, and LED displays, screensavers serve a different purpose than they once did. They're mostly cosmetic — a moving image or animation that appears after a set idle period. Some users set them to display clocks, photo slideshows, or network information. Others use them as a loose security layer, pairing the screensaver timeout with a lock screen prompt so anyone returning to the machine must authenticate.

It's worth knowing that sleep mode does more for energy efficiency than any screensaver. But if you have a specific use case — a display kiosk, a shared office computer, or simply personal preference — knowing how to configure yours is useful.

How to Change a Screensaver on Windows

Windows has kept screensaver settings in roughly the same place for years, though the path to get there has shifted slightly between versions.

On Windows 10 and Windows 11:

1. Right-click the desktop and select Personalize
2. Navigate to Lock Screen in the left sidebar
3. Scroll down and click Screen saver settings
4. In the dialog box, use the dropdown menu under Screen saver to choose an option
5. Set your preferred Wait time (how many idle minutes before it activates)
6. Check On resume, display logon screen if you want it to lock
7. Click Apply, then OK

Built-in options include Blank, Bubbles, Mystify, Photos, Ribbons, and 3D Text. The Photos option lets you pull from a specific folder on your drive — useful for turning a monitor into a slideshow display.

Third-party screensavers (downloaded .scr files) install into your Windows system folder and then appear automatically in that same dropdown menu.

How to Change a Screensaver on macOS 🖥️

Apple has reorganized screensaver settings a few times across macOS versions, so the exact path varies slightly depending on whether you're running Ventura, Sonoma, or an older release.

On macOS Ventura and later:

1. Open System Settings (the gear icon)
2. Click Screen Saver in the sidebar
3. Browse the available options — Apple offers several built-in styles including Shuffle, Hello, and various aerial landscape animations
4. Click a screensaver to preview it
5. Adjust the Show after idle time using the dropdown

On macOS Monterey and earlier:

1. Go to System Preferences
2. Open Desktop & Screen Saver
3. Click the Screen Saver tab
4. Select from the list on the left, preview on the right
5. Set your start time with the Start after slider

macOS screensavers tend to be more visually polished than Windows defaults, and Apple regularly adds new ones tied to macOS releases. Third-party screensavers on Mac install as .saver files — typically by double-clicking the file, which places it in your Library folder automatically.

Variables That Change the Experience

Getting to the screensaver setting is the easy part. What you actually have available — and how it behaves — depends on several factors:

Operating system version. The menu paths above reflect current releases. Older versions of Windows or macOS may have the setting buried elsewhere, or may lack some of the newer built-in screensaver options.

User account permissions. On managed devices — corporate laptops, school computers, family accounts — an administrator may have locked screensaver settings through Group Policy (Windows) or Mobile Device Management (MDM) profiles. You might see the setting greyed out or missing entirely. In those cases, changing it requires admin access or a policy change from whoever manages the device.

Display hardware. If you're running multiple monitors, screensaver behavior may differ across screens depending on your OS and graphics configuration. Some systems apply the screensaver to all displays simultaneously; others treat each display independently.

Third-party screensavers. Downloading screensavers from external sources introduces variability — and some risk. Malicious .scr files have been used to distribute malware, so source matters. Screensavers from well-known developers or open-source projects carry far less risk than random downloads.

Power settings interaction. Screensaver timeout and sleep/display-off timers often overlap. If your display is set to turn off after 5 minutes but your screensaver is set to activate after 10 minutes, you'll never actually see the screensaver. Coordinating these settings in your power options is part of getting the behavior you want. ⚙️

What Screensaver Settings Don't Tell You

The settings panel shows you which screensaver to use and when to activate it — but it doesn't tell you whether that's the right configuration for your situation. A machine running as a public display kiosk has completely different needs than a home desktop, a locked-down corporate workstation, or a media center PC. The idle timeout, the lock screen behavior, whether to use a screensaver at all versus just sleep mode — those decisions hinge on how the device is actually being used and who has access to it. 🔐
