In Windows 11, a screen saver normally covers every connected monitor, so there’s no separate “both monitors” switch to turn on. Set your displays to Extend (press Windows logo key + P), then turn on a screen saver in Settings > Personalization > Lock screen > Screen saver. Most built-in screen savers then run across all your screens.
If the screen saver only shows on one monitor, the cause is usually the screen saver you picked (the Photos screen saver is the most common culprit), your display mode, or a power setting that turns a screen off first. This guide covers the setup, explains why results vary, and walks through the fixes.
Quick Answer
- Press Windows logo key + P and choose Extend.
- Open Settings > Personalization > Lock screen, then select Screen saver under Related settings.
- Pick a screen saver from the list, set the Wait time, and click Preview.
- Click Apply, then OK.
- If only one monitor shows it, try a different screen saver and check that your screen-off timeout is longer than the screen saver’s wait time.

How Screen Savers Work with Two Monitors
A screen saver is an animation or slideshow that Windows starts after your PC has been idle for a set number of minutes. Windows 11 runs one screen saver at a time for the whole desktop; there’s no built-in setting to choose which monitor it appears on or to run a different one on each screen.
In practice, that means:
- Most built-in screen savers fill every monitor. Microsoft community answers describe Windows screen savers as using the full desktop area across connected displays by default, though Microsoft’s main support article doesn’t spell out multi-monitor behavior.
- Some screen savers behave differently. Users have reported that the Photos screen saver shows pictures only on the main monitor in some Windows 11 versions, while in others a single picture is split across the middle of two screens. Behavior can change after Windows updates.
- Your display mode matters. If Windows is set to show only on one screen, the other monitor is off and can’t show anything.
So “getting the screen saver on both monitors” is mostly about picking a screen saver that fills every display and making sure nothing turns a monitor off first.
Before You Start
- Windows 11, with both monitors connected and working. The steps also apply to Windows 10, although some Settings labels differ.
- Both monitors detected. If you haven’t set up your second screen yet, see how to use dual monitors in Windows 11 first.
- A personal PC, or permission on a work PC. On a work or school computer, your organization may manage or lock screen saver settings.
This guide reflects Windows 11 as of September 2026.
Step 1: Set Your Display Mode
Windows has four ways to use multiple displays. According to Microsoft’s multiple monitors guide, you can switch between them with Windows logo key + P.
| Mode | What it does | Screen saver on both? |
|---|---|---|
| PC screen only | Uses only the main display | No; the other screen is off |
| Duplicate | Shows the same thing on all displays | Yes; both show the same image |
| Extend | Spreads your desktop across all displays | Usually yes, depending on the screen saver |
| Second screen only | Uses only the external display | No; the main screen is off |
- Press Windows logo key + P. Expected result: A panel with the four options opens.
- Select Extend for a normal dual-monitor setup, or Duplicate if you want both screens to mirror each other.
- To confirm, open Settings > System > Display. Both monitors should appear as numbered boxes. Click Identify to see which number belongs to which screen.
Step 2: Turn On the Screen Saver
The screen saver controls still live in the classic Screen Saver Settings window, which you open from Settings. The steps below follow Microsoft’s screen saver support article.
- Open Settings (press Windows logo key + I).
- Select Personalization, then Lock screen.
- Scroll to Related settings and select Screen saver. Expected result: The Screen Saver Settings window opens.
- Under Screen saver, open the drop-down list and pick one. Windows includes options such as Bubbles, Mystify, Ribbons, 3D Text, Blank, and Photos.
- Set Wait to the number of idle minutes before the screen saver starts.
- Optional: check On resume, display logon screen so your PC asks for your PIN or password when you come back. This is a good idea on shared or work computers.
- Optional: click Settings… to customize the screen saver, if it has options (for example, choosing a folder for Photos).
- Click Preview and look at both monitors. Move the mouse to end the preview. Expected result: The screen saver appears on both screens.
- Click Apply, then OK.
If the preview only shows on one monitor, pick a different screen saver from the list and preview again before changing anything else. That quickly tells you whether the problem is the screen saver itself.
For more on the basic setup, see how to turn on the screen saver in Windows 11.
Step 3: Check Your Power Settings
Windows can turn your screens off to save power. If that timeout is shorter than your screen saver’s wait time, the monitors go dark before the screen saver ever starts, which can look like the screen saver isn’t working.
- Open Settings > System > Power & battery.
- Expand Screen, sleep, & hibernate timeouts.
- Set Turn my screen off after to a longer time than your screen saver’s Wait setting. For example, if the screen saver starts after 5 minutes, turn the screen off after 15.
- Check Make my device sleep after as well, so the PC doesn’t sleep before the screen saver has a chance to run.
Laptops show separate settings for when they’re plugged in and on battery. Set both if you use the laptop with external monitors on battery. Microsoft’s power and sleep settings article covers these options.
Also worth knowing: Microsoft notes that sleep uses significantly less power than running a screen saver. If your goal is saving energy rather than decoration, letting the screens turn off is the better choice.
Which Screen Saver Should You Choose?
| Screen saver | Typical multi-monitor behavior | Good for |
|---|---|---|
| Bubbles, Mystify, Ribbons | Animate across the whole extended desktop | Reliable coverage on both screens |
| Blank | Blacks out the displays | Privacy; a simple dark screen on both monitors |
| 3D Text | May appear only on the main display in some versions | A single-screen message or clock |
| Photos | Varies: main display only, or one image split across screens | Slideshows, if you accept the quirks |
The behavior in this table comes from user reports and Microsoft community answers, not from Microsoft’s support documentation, and it can differ between Windows versions and graphics drivers. Use Preview to check what yours does.
Can a Picture Span Both Monitors?
Not reliably with the built-in Photos screen saver. It has no option to stretch one image across two screens on purpose, and when it does split an image, users report the result looks cut in half rather than designed.
If you want one wide image across both monitors, the desktop background is a better fit:
- Find a picture sized for your combined screens (for two 1920 x 1080 monitors side by side, that’s 3840 x 1080).
- Open Settings > Personalization > Background.
- Set the background type to Picture and select your image.
- In the fit list (labeled Choose a fit for your desktop image in current versions), choose Span.
Then pair it with a screen saver such as Blank, or rely on your screen-off timeout, so both monitors behave the same when you step away.
Want Something Different on Each Monitor?
Windows 11 has no built-in way to run a screen saver on just one monitor or a different screen saver on each. If you need that, you have two options:
- Change the display mode when you step away. Press Windows logo key + P and choose PC screen only to turn off the second screen. It’s manual, and your windows may move when you switch back.
- Use a third-party multi-monitor utility. Some paid and free display-management tools add per-monitor screen savers. If you go this route, download only from the developer’s official website, and turn off the Windows screen saver (set it to (None)) so the two don’t conflict.
Avoid registry “tweaks” found online for this; they’re unreliable and editing the registry incorrectly can cause problems.
Troubleshooting
The screen saver shows on only one monitor
- Press Windows logo key + P and make sure Extend or Duplicate is selected.
- Switch to Bubbles or Ribbons and click Preview. If those fill both screens, the original screen saver is the limitation.
- Check that Turn my screen off after is longer than the screen saver’s Wait time.
- Update your graphics driver through Settings > Windows Update, or from your PC or graphics card maker’s website.
The second monitor isn’t detected
Check the cable at both ends, then go to Settings > System > Display, expand Multiple displays, and select Detect. Microsoft also recommends checking for Windows updates.
The screen saver never starts
- Make sure a screen saver is selected, not (None), and that you clicked Apply.
- Video players, games, and presentations can keep the PC awake, which stops the idle timer. Close them and test again.
- A mouse that jitters or a wireless device sending input can reset the timer. Try leaving the mouse on a flat, still surface.
One screen stays lit or shows the desktop
This has been reported with docking stations and laptops used with the lid closed. Try choosing Second screen only or the “show only on” option for the external display in Settings > System > Display so the laptop panel is fully off, and report the issue through the Feedback Hub app.
Screen saver options are grayed out
On a work or school PC, your organization can manage screen saver settings, including the wait time and whether a password is required. If the options are grayed out or reset themselves, ask your IT department rather than trying to change them.
The Photos screen saver cuts pictures in half
That’s a known quirk on extended desktops. Use Duplicate mode if you want the same full picture on both screens, or choose a different screen saver.
Frequently Asked Questions
Does Windows 11 have a setting to put the screen saver on both monitors?
No separate setting is needed. With the displays in Extend or Duplicate mode, most screen savers cover every connected monitor.
Can I run a different screen saver on each monitor?
Not with Windows alone. You’d need a third-party multi-monitor tool.
Why does the Photos screen saver only use my main monitor?
The Photos screen saver handles multiple monitors differently from the animated ones, and users report it varies between Windows versions. Try Duplicate mode or another screen saver.
Do I still need a screen saver to protect my monitors?
For most people, no. Microsoft notes that modern LCD and LED monitors have minimal burn-in risk, though screen savers can still help on OLED displays. Turning screens off saves more power.
Does this work with a TV as the second screen?
Yes. Windows treats a TV connected by HDMI as another display, so the same display modes and screen saver settings apply. Keep in mind that some TVs go into their own standby when the signal is idle.
What happens if I unplug one monitor?
The screen saver keeps working on the display that’s still connected. Your settings stay the same, so it covers both screens again when you reconnect the second monitor.
How do I turn the screen saver off again?
Open Screen Saver Settings and choose (None), then click Apply. For more detail, see how to turn off the screen saver in Windows 11.
Summary
- Windows 11 runs one screen saver for the whole desktop; there’s no per-monitor setting.
- Press Windows logo key + P and choose Extend or Duplicate.
- Open Settings > Personalization > Lock screen > Screen saver, pick one, and preview it.
- Choose an animated screen saver such as Bubbles or Ribbons for reliable coverage on both screens.
- Make the screen-off timeout longer than the screen saver’s wait time.
- Use a spanned desktop background for a single wide image.
Next step: open Screen Saver Settings, choose Ribbons, and click Preview to confirm it covers both of your monitors.
