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

Screensavers have been around since the early days of personal computing, originally designed to prevent phosphor burn-in on CRT monitors. Modern displays don't have that problem, but screensavers remain popular for privacy, aesthetics, and energy management. If you want to swap yours out, the process varies depending on your operating system — and there are more options than most people realize.

What a Screensaver Actually Does

A screensaver is a program that activates after your computer sits idle for a set period. On modern systems, it serves a few practical purposes:

• Privacy: Hides your screen from passersby when you step away
• Power signaling: Often works alongside sleep settings, though it's distinct from them
• Personalization: Lets you display photos, animations, or simple graphics

It's worth knowing that a screensaver and sleep mode are not the same thing. Sleep mode cuts power to components to save energy. A screensaver keeps the display active but replaces whatever was on screen. Some users enable both; others skip screensavers entirely and rely on sleep alone.

How to Change Your Screensaver on Windows 🖥️

Windows 10 and Windows 11 both support screensavers, though Microsoft has quietly tucked the settings deeper into menus over time.

Step-by-step on Windows 10/11:

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

Windows includes several built-in options: Blank, Bubbles, Mystify, Photos, Ribbons, and 3D Text. The Photos screensaver lets you pull in images from a specific folder, which is useful if you want a rotating personal gallery.

Custom screensavers (.scr files) can be downloaded from third-party sources and installed by right-clicking the file and selecting Install. They then appear in the same dropdown menu.

A Note on Windows 11

Windows 11 reorganized its settings interface. If you can't find the screensaver option through Personalize, use the search bar and type "screensaver" — the direct link to the settings dialog will appear immediately.

How to Change Your Screensaver on macOS 🍎

Apple integrates screensaver settings into System Settings (formerly System Preferences on older macOS versions).

On macOS Ventura and later:

1. Open System Settings from the Apple menu
2. Click Screen Saver in the sidebar
3. Choose a screensaver from the list on the left
4. Adjust the Show after timer using the dropdown
5. Some screensavers have a Style or Shuffle option for customization

On macOS Monterey and earlier:

1. Open System Preferences
2. Click Desktop & Screen Saver
3. Select the Screen Saver tab
4. Browse options and set your idle time

macOS offers visually polished options including aerial landscape videos (similar to Apple TV's Aerial screensaver), photo slideshows, and abstract animations. Third-party screensavers are also available but must be installed as .saver files, typically placed in ~/Library/Screen Savers.

Screensavers on Other Platforms

Linux users running different desktop environments (KDE Plasma, XFCE, etc.) will find screensaver options in different places, and support varies considerably by distribution and environment.

Variables That Affect Your Setup

Changing a screensaver sounds simple, but a few factors determine what's actually available to you:

Operating system version matters more than people expect. Older versions of Windows or macOS may have the settings in completely different locations, and some older systems don't support newer screensaver formats.

Administrator permissions can block changes on work or school machines. If you're on a managed device through an employer or institution, screensaver settings — including lock screen timers — may be controlled by IT policy and grayed out for individual users.

Display configuration plays a role on multi-monitor setups. Some screensavers behave differently across extended displays versus mirrored ones, and not all third-party options are built to handle multiple screens gracefully.

Custom screensaver compatibility is a real concern. A .scr file built for Windows XP may not run correctly on Windows 11. Always check that any third-party screensaver is designed for your current OS version.

Performance overhead is minimal for most built-in screensavers, but some third-party options — particularly those rendering complex 3D graphics or running visualizations — can put load on your GPU. This matters more on older hardware or on laptops running on battery.

The Difference Between a Screensaver and a Lock Screen

These two things are often confused. A lock screen secures your device behind a password or PIN after a period of inactivity. A screensaver is purely visual and may or may not require authentication to dismiss, depending on your settings.

On Windows, the option to require a password when the screensaver ends is a checkbox in the same dialog where you pick the screensaver. On macOS, it's controlled separately under Privacy & Security → Screen Saver settings. Getting this distinction right matters if privacy is part of why you're enabling a screensaver in the first place.

What the Right Choice Actually Depends On

For most home users on a modern system, changing a screensaver takes under two minutes. But whether a blank screen, a photo slideshow, an animated pattern, or a third-party option makes the most sense for your situation comes down to things only you know: whether you're on a shared machine, how your power and sleep settings are already configured, what your OS version supports, and whether you're on a managed device where settings might be restricted. The mechanics are straightforward — the best configuration is more personal than it might seem.
