Can you run a different live wallpaper on each monitor on a Mac?
Short answer: yes, and each screen runs independently, including different kinds of wallpaper on each one. The parts worth knowing are what happens when you unplug a monitor, and what the second screen actually costs you.
Multi-monitor setups are where live wallpaper apps quietly fall apart. Plenty of them will happily animate your main screen and then treat the second one as an afterthought: the same wallpaper mirrored everywhere, or a second screen that goes blank, or an assignment that scrambles itself the first time you undock a laptop.
I build a live wallpaper app for macOS, so treat me as an interested party. What I can do is be specific about how per-display wallpapers actually behave, including the two places mine still has limits, so you can compare it against whatever else you are looking at.
What macOS gives you on its own
macOS has let you set a different still picture on each display for years. Open System Settings, go to Wallpaper, and each connected screen gets its own selection. That part is solved and has been for a long time.
The moment you want something moving on more than one screen, you are into third-party territory, and this is where the differences show up. The question to ask any app in this category is not whether it supports multiple displays, because almost all of them say yes. It is whether each display is a real independent slot, or whether the second screen is getting a copy of the first.
How per-display wallpapers work in Vivid Walls
Every connected display is its own slot with its own wallpaper, running on its own. Nothing is mirrored unless you deliberately set the same wallpaper twice.
They also do not have to be the same kind of wallpaper. Vivid Walls handles animated Wallpaper Engine scenes, video files, web wallpapers, GIFs and still images, and the type you choose for one display puts no constraint on the others. A scene on the main display, a 4K video loop on the second and a still image on a third is a normal setup, not a special case.
Two ways to put a wallpaper on a specific screen
The sidebar of the main window lists your connected displays. The most direct way to assign a wallpaper is to drag it from the library grid onto the display you want it on. It applies immediately.
The other way is to select a wallpaper and use its inspector on the right. When more than one display is connected, a Display picker appears above the Apply button. Choose the screen, hit Apply, done. On a single-display Mac that picker is hidden, because there is nothing to choose.
One thing worth knowing so it does not surprise you: the right-click Apply to Desktop shortcut in the library grid does not ask which screen. It goes to the first connected display. It is a fast path for single-display use, so when you care which monitor gets what, use the drag or the picker instead.
The Displays tab
Settings has a Displays tab that draws your monitors in their actual arrangement, the way the macOS display arrangement view does. Selecting a display shows its name and resolution, whether it currently has a wallpaper, and a button to remove that wallpaper from that screen alone. It refreshes on its own when you plug or unplug something, so it is a reliable place to check what is actually assigned where.
The part people actually get burned by, which is unplugging
This is the bit that separates apps that took multiple displays seriously from apps that ticked the box.
macOS hands out an ID number for each display, and those numbers are not stable. They can change when you dock, undock, restart, or change the arrangement. An app that keys its wallpaper assignments to that number will eventually put the wrong wallpaper on the wrong screen, or forget the assignment entirely, and to you it looks like the app randomly lost your setup.
Vivid Walls keys assignments to the monitor's own identity rather than that temporary number. When you disconnect a display, its wallpaper assignment is preserved rather than discarded, and when that same monitor comes back it gets its wallpaper back. The mapping is also saved between launches, so it survives quitting the app and restarting the Mac.
The practical version: dock your MacBook at your desk, undock it for a meeting, dock it again, and the external monitor picks up where it left off. You should not have to reassign anything.
What a second display costs you
The honest answer is that it costs about what you would expect. The work of drawing an animated wallpaper scales with how many pixels it draws and how often, so adding a second screen adds a second screen's worth of pixels. Two 4K displays is roughly twice the pixel budget of one, and a 5K display is a lot of pixels on its own. I went through the mechanics of this in detail in do live wallpapers drain your MacBook battery, and all of it applies per screen.
The two controls that matter most are the same ones as on a single display. The frame rate cap is 30 frames per second when plugged in by default, not 60, and it drops to 15 on battery, with the option to pause entirely on battery instead. And the pause rules stop the rendering when there is nothing worth drawing: display sleep, a fullscreen app covering the desktop, and 15 minutes without input.
There is one multi-monitor detail in those rules that is worth stating plainly. Pausing because windows are covering the wallpaper only kicks in when every wallpaper window is covered. If your laptop screen is buried under windows but your external monitor is showing a clear desktop, the wallpapers keep running, which is the correct behaviour because you can still see one of them. It does mean that on a two-screen setup, a permanently visible second screen is a wallpaper that is genuinely rendering most of the day. That is the thing you are paying for, and if you would rather not, the frame cap is the lever.
A setup that works well in practice: put the cheap thing on the screen you work on and the showy thing on the screen you glance at. A still image or a calm scene on the monitor covered in windows costs you nothing to look at, because you are not looking at it.
Where it still has limits
Two, and I would rather you hear them from me than find them.
Playlists run one at a time, on one display. You can point a playlist at whichever screen you like and it will cycle wallpapers there on a timer, but starting a playlist stops any playlist that was already running. You cannot cycle one set of wallpapers on the left monitor and a different set on the right. Fixed wallpapers on your other displays are unaffected and keep running normally, so a playlist on the main screen next to a fixed scene on a second screen is fine. Two playlists at once is not.
Pausing is app-wide, not per-display. When a pause rule triggers, such as going fullscreen or walking away, every wallpaper pauses rather than just the one on the affected screen. For battery and heat this is the behaviour you want. If you were hoping to pause one monitor while another keeps animating, that is not a switch that exists.
Common questions
Can you have a different live wallpaper on each monitor on a Mac?
Yes. Every connected display is its own slot with its own wallpaper, and the displays run independently. They do not have to be the same kind either: an animated scene on one, a 4K video loop on a second and a still image on a third all work at the same time.
What happens to my external monitor's wallpaper when I unplug it?
It is kept, not lost. Assignments are tied to the monitor's own identity rather than the temporary display number macOS assigns, so docking again puts the same wallpaper back on the same screen. The mapping is saved between launches too, so it survives a restart.
Does running a live wallpaper on two monitors use twice the power?
Roughly, yes, because the cost of a frame scales with the pixels being drawn and a second display adds a second screen of them. The frame rate cap and the pause rules are what actually control it: 30 frames per second plugged in by default, 15 on battery, and rendering stops on display sleep, on fullscreen, and after 15 minutes without input.
Can I mix a live scene on one display and a video wallpaper on another?
Yes. Each display is handled separately, so the type on one screen does not constrain the others. A lighter scene or a still image on the screen you work on and a more elaborate one on the screen you glance at is a good default.
Can I run a different playlist on each monitor?
Not currently. One playlist cycles at a time, on one display of your choosing, and starting a playlist stops any playlist already running. Fixed wallpapers on the other displays are unaffected.
