Steam Big Picture’s screensaver is configured under Settings > Customization. There you can choose a built-in screensaver, use a custom one, or adjust its behavior; a separate setting can suppress it while a game is running. Steam also has a controller idle turn-off timeout, but Valve’s available documentation does not establish its current menu path or time choices, so check the controls shown in your installed client rather than relying on an outdated menu guide.
What do you need before changing the settings?
Open Steam in Big Picture Mode and use the client’s current settings screens. The screensaver controls described here come from Valve’s October 13, 2026 stable client update. If your client does not show them, check that Steam has updated; menu labels and options can change between client versions.

You do not need a special controller, cable, television, monitor, subscription, or printed guide to change these settings. The built-in controls are part of the Steam client. A custom screensaver may require access to the Steam installation directory or your user configuration directory, but there is no purchase requirement for the configuration itself.
Keep three separate behaviors in mind: the general Big Picture screensaver, the option to suppress it during gameplay, and the controller’s idle turn-off timeout. They are not the same setting. The battery and AC power idle timers are a further, separate category. Identifying which behavior you want to change prevents you from adjusting a setting that appears related but has no effect on the problem you are seeing.

How do I change or stop the Big Picture screensaver?
- In Big Picture Mode, open Settings, then select Customization. Valve identifies this as the screensaver settings location in its October 13, 2026 Steam Client Update.
- Review the screensaver controls displayed in that section. Choose a built-in option, a custom option if your client exposes one, or the general disable control if one is shown.
- Choose a screensaver option available in that section. Valve documents a game-art slideshow and a retro-style bouncing-logo screensaver. The slideshow can show artwork from recently played games and recent in-game screenshots.
- If your goal is to stop the screensaver only while playing, look for the setting to disable the screensaver while in a game and enable it. This is a gameplay-specific control; Valve’s update does not say it turns off the screensaver throughout Big Picture.
- If you want no screensaver during general Big Picture idle periods, use the screensaver controls in Customization to select or disable the general feature if your client presents that choice. Valve’s release note confirms the feature and location but does not enumerate every current toggle or label, so follow the options shown in your version.
After changing a choice, leave the settings page and let Big Picture sit idle long enough to observe the result. If the screen remains active during a game but still shows a screensaver in menus, that is consistent with the two controls having different scopes. If the display powers off entirely, investigate operating-system power settings separately; the Steam notes do not say that the Big Picture screensaver controls monitor sleep.
What do the built-in screensaver choices show?
The game-art slideshow is the choice for a library-focused idle screen. Valve describes it as configurable to show artwork from recently played games and recent in-game screenshots. The material therefore changes as your play history and captured screenshots change. It is not described as a general photo viewer, and Valve does not publish a separate interval, ordering control, or file-import procedure for this built-in option.
Recommended Free Tools
The bouncing-logo screensaver is a retro-inspired animation. Its content is the Steam logo treatment rather than game-specific artwork. Valve points to the corresponding built-in item in Steam’s steamuiscreensavers directory as an example to inspect. Looking at that directory can help you distinguish a built-in asset from an override, but it does not establish that copying or renaming arbitrary files will create a working custom screensaver.
Custom screensavers are a third category. They require placing files in the documented override directory, and then the installed client must recognize the files and expose the custom choice. Valve’s note does not specify supported formats, dimensions, codecs, naming conventions, or whether a restart is required. Treat the directory as the documented place to start, not as a guarantee that every image, animation, or video will load.
Can I disable it only while a game is running?
Yes, Valve’s October 13, 2026 stable notes add a Big Picture setting to disable the screensaver while in a game. Open Settings > Customization, locate the gameplay-related wording, and enable it if you want gameplay to take priority over the idle animation.
This option is useful when a game is paused, displaying a cutscene, or waiting for input but you still want the game session to remain visible. It does not necessarily disable the screensaver on the Big Picture home screen, library pages, or other non-game views. Valve specifically describes the scope as being while in a game, so do not interpret it as a global off switch unless your client separately provides that control.

If the option appears enabled but a screen still dims during a game, first determine whether you are seeing Steam’s screensaver or the operating system’s display-sleep behavior. The release notes cover Steam’s screensaver handling, not the operating system’s power policy. A display that turns completely off can be responding to a system timer even when the Steam gameplay option is working.
How do I add a custom screensaver?
Steam documents a custom screensaver directory for both Linux and Windows. Place the custom screensaver files in the directory for your operating system, then return to Big Picture’s screensaver options to see whether the client offers the custom item.
- Linux:
~/.steam/root/config/uioverrides/screensavers/ - Windows:
config\uioverrides\screensaversunder the Steam installation directory. Valve givesC:\Program Files (x86)\Steamas an example of an install root, so the corresponding example directory isC:\Program Files (x86)\Steam\config\uioverrides\screensavers.
The Windows path is relative to the Steam installation directory. If Steam is installed somewhere other than the example location, substitute that actual root and retain the config\uioverrides\screensavers portion. On Linux, the leading tilde represents your user home directory; use the home directory belonging to the account that runs Steam.
Use the exact spelling and directory structure shown above. Creating a similarly named folder elsewhere, such as inside a game library, will not be the documented override location. If the folder does not already exist, the release note does not explain whether Steam creates it automatically, so create the final directory only where you have confirmed the Steam root or user configuration path.

If no custom choice appears, do not assume the file is valid merely because it is in the folder. Valve does not state the accepted formats or a complete installation sequence. Check the client’s displayed options, verify the path, and remove or move the file if it causes unexpected behavior.
Valve points to the bouncing-logo screensaver in Steam’s steamui\screensavers directory as an example to inspect. That reference helps identify where a built-in asset resides, but the notes do not instruct users to edit Steam’s installed files. Prefer the override directory for experiments so that client updates do not overwrite modified installation files.

How do I change the controller’s idle turn-off timeout?
Steam confirms that Big Picture has a controller idle turn off timeout setting, but the available Valve documentation does not verify the current navigation path or selectable durations. Open the installed client’s settings and look for the controller idle or turn-off timeout control; use the options actually displayed there.
Because the current menu path is not established, avoid guides that confidently name a particular submenu if their instructions were written for an older client. Menu organization can change independently of the feature itself. Search the settings categories visible in your version for wording such as idle, turn off, or timeout, and distinguish a controller-specific control from general device power settings.
The Tool Desk
Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Valve’s older Steam Client Update Released establishes that this timeout feature exists, but it is not a reliable source for today’s menu location or values. In particular, do not use a timer value from an older guide as though it were confirmed for your current client. Select only a duration that your installed client actually lists; no numeric choices are published in the cited notes.
This timeout controls whether the controller turns off after inactivity. It is distinct from whether Steam displays a screensaver: changing one should not be treated as changing the other. A controller can turn off while the Big Picture screen remains visible, and a screensaver can appear while a controller remains powered, depending on the two independent settings and the activity each one measures.
How can I verify that a controller timeout change worked?
Start with a fully charged or connected controller and note the option you selected. Stop pressing buttons and moving sticks, then wait for the duration shown by your client. The cited Valve notes do not promise an exact countdown display or explain how wireless accessories report power-off, so use the controller’s own status light, connection indicator, or Steam input response as your practical check.
If the controller remains on, check whether another input source is generating activity. A second controller, a connected keyboard, a mouse, or an application that continually polls the device may prevent the idle condition from being reached. The documentation does not define every activity event that resets the timer, so avoid treating one brief test as proof that the setting is missing.

If it turns off sooner than expected, verify that you changed the controller timeout rather than a battery or AC idle timer. Those controls belong to a different category. Also check whether the controller itself has a manufacturer power policy; Steam’s documented setting is the Big Picture controller idle turn-off feature, not a universal override for every controller firmware behavior.
What are the battery and AC idle timers?
Battery and AC power idle timers are device power controls, not the controller timeout or the screensaver timer. Valve said the battery and AC idle timer settings were reorganized in the October 13, 2026 update, but did not publish the current menu path or a list of timer values in that note.
If you are trying to keep a device awake or change how it behaves on battery versus plugged in, inspect those power-related controls separately in your installed client. A setting for battery may apply only while the device is unplugged, while an AC setting may apply while power is connected, but the cited notes do not enumerate their exact behavior or values. Do not infer their settings from the controller turn-off timeout or from the screensaver’s behavior.
The reorganization also means an older screenshot may no longer match your menus. Use the labels and categories displayed by the current client, and record which power state you were testing. Changing an AC timer will not necessarily alter a controller’s wireless idle behavior, and changing a screensaver selection will not rewrite either battery or AC policy.

Valve says Steam delays screen dimming or screensaver display when the Steam Store, web browsers, or other apps request that monitor sleep and screensavers be disabled during video playback. This behavior can explain why the screensaver does not appear on its usual schedule while video is playing; Valve’s note does not provide a separate timer setting for that delay.
The delay is therefore not evidence that the Customization setting failed. A browser video, Store video, or another application can request that the monitor remain awake. Once playback ends or the application releases that request, normal dimming or screensaver behavior may resume according to the client and system settings.

There is no documented numeric override to enter for this video-playback behavior. If you need to test the screensaver, stop the video and close or minimize the application making the request, then allow Big Picture to remain idle. If the display still sleeps completely, compare the result with your operating system’s display and power controls.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How do the controls compare?
| Control | What it changes | Where to start | What Valve does not specify |
|---|---|---|---|
| General screensaver | What Big Picture shows during its idle state, such as game art or the bouncing logo | Settings > Customization | Every current toggle, timer value, and label |
| Disable during gameplay | Suppresses the Steam screensaver while a game is running | The gameplay-related option in the screensaver settings | Whether it affects non-game screens |
| Custom screensaver | Uses content placed in an override directory if the client recognizes it | Windows or Linux screensaver override path | File formats, codecs, naming rules, and restart requirements |
| Controller turn-off timeout | Turns an idle controller off after the client’s configured inactivity period | The controller idle or turn-off control in your installed client | Current menu path and selectable durations |
| Battery/AC idle timers | Device power behavior for battery and connected-power states | The separate power-related controls | Current menu path, values, and exact scope |
The comparison matters because similar words such as idle, sleep, and timeout can refer to different systems. Choose the row that matches the symptom: animated content on an idle Big Picture screen, a screensaver appearing in a game, a controller losing power, or a device changing behavior between battery and AC power.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteCommon pitfalls and troubleshooting checks
- Using the wrong menu: Start at Settings > Customization for screensaver controls. Do not expect a controller timeout change to appear in the screensaver section.
- Assuming gameplay suppression is global: The added option is described as disabling the screensaver while in a game. Test the home screen separately.
- Confusing a dark display with a screensaver: Steam’s notes do not document operating-system display sleep. Check system power settings when the monitor turns off.
- Copying an old timeout value: Valve confirms the controller feature but does not publish current durations in the cited notes. Use only values shown by your client.
- Putting custom files in the wrong place: Use the documented Linux path or the Windows path relative to the Steam installation root, not a game library folder.
- Assuming every file works: Supported custom formats are not specified. Directory placement alone does not guarantee recognition.
- Testing during video playback: Store pages, browsers, and other apps can request that sleep and screensavers be delayed.
- Mixing battery and AC settings with controller behavior: Those timers were reorganized separately and should be tested in the appropriate power state.
- Editing built-in Steam files: The bouncing-logo location is an example to inspect, not an instruction to modify installed assets. Use the override directory for custom content.
Is any hardware or paid software required?
No. Selecting a built-in screensaver, enabling gameplay suppression, and reviewing the controller timeout are Steam client configuration tasks. A television, monitor, controller charging cable, dock, replacement controller, or subscription is not prescribed by Valve for these changes. Hardware may affect how a device reports power or how an operating system handles sleep, but buying equipment is not a requirement for following the documented setup.
Which setting should I change?
- Stop idle Big Picture screensaver behavior: use Settings > Customization and the general screensaver options shown in your client.
- Keep it from appearing during a game: enable the gameplay-specific disable-screensaver setting.
- Turn off an idle controller: find the controller idle turn-off timeout in the installed client and choose a listed value.
- Change battery-versus-AC device behavior: use the distinct battery/AC idle timer controls, whose organization changed in the October 2026 update.
- Use your own screensaver content: place files in the documented operating-system override directory, then check whether Big Picture recognizes them; do not assume an unsupported format will work.
- Keep the screen awake during a video: understand that Steam may already delay dimming or screensaver display when an app requests that behavior, and do not search for a timer value Valve has not documented.
Frequently Asked Questions
Does Steam Big Picture’s screensaver change my PC’s display sleep settings?
Valve’s cited release notes do not describe the relationship between the Big Picture screensaver and operating-system display sleep. If the display itself turns off, check the operating system’s power settings separately rather than assuming the Steam screensaver controls it.
Why is the screensaver delayed when I’m watching a video?
Steam may delay dimming or screensaver display when the Store, a browser, or another app requests that monitor sleep and screensavers be disabled during video playback. Valve does not document a separate timer for this behavior.
Can I use a custom screensaver on both Windows and Linux?
Valve documents custom screensaver override directories for both operating systems: a path under the Steam install directory on Windows and one under `~/.steam/root` on Linux. The update note does not specify supported file formats, so directory placement alone does not guarantee that an arbitrary file will be recognized.

One-click scans. No signup required.
Where exactly is the Big Picture screensaver setting?
Open Big Picture Mode and go to Settings > Customization. Valve identifies that location for the screensaver feature in its October 13, 2026 stable client update. The labels and available controls may differ if your client has not reached that version.
Can I disable the screensaver only during games?
Yes. Valve added a separate option to disable the screensaver while in a game. That scope is gameplay-specific; it should not be assumed to disable the screensaver on the Big Picture home screen or other non-game pages.
The Bottom Line
For screensaver changes, start with Settings > Customization. Choose the game-art slideshow, bouncing-logo animation, or a recognized custom option; enable the separate gameplay switch if you only want to suppress it while a game runs. Treat the controller idle turn-off timeout and the battery/AC idle timers as independent controls, and rely on the options shown in your current Steam client because Valve has not published a current path or numeric list for those timers.
