How to Run Different Live Wallpapers on a Dual-Monitor Setup
A dual-monitor setup changes how you use a desktop more than any other single upgrade. The second screen stops being a mirror of the first almost immediately - it becomes a dedicated space for reference material, chat, music, documentation, or the occasional distraction you do not want cluttering your main view. Once your workflow separates across two displays, it starts to make sense that the two screens should look different too. Not just in what windows they hold, but in the ambient layer underneath everything: the wallpaper.
Gloomia supports independent wallpaper assignment per monitor. You can run Starfield on the left and Galaxy Spiral on the right, slow and calm on the work side, visually alive on the secondary. This guide covers how to set that up, which pairings work well for different setups, how audio reactivity behaves across two screens, and what to expect from GPU usage.
How per-display wallpaper assignment works
When you open Gloomia with two or more monitors connected, the app shows each display as a separate target in its sidebar. Clicking a display selects it and shows the current wallpaper assigned to it. You can browse the wallpaper library and apply any wallpaper to the selected display independently from the others. Changes take effect immediately.
Each display has its own set of knobs - speed, color theme, intensity, audio reactivity - so the Starfield on your left monitor can run at its default slow drift while the Galaxy Spiral on the right runs at a faster rotation and a warmer color palette. These settings are saved per-display and restore on next launch, so you do not have to reassign every time you restart.
If you connect a third monitor, it appears in the same sidebar and gets its own independent assignment. Gloomia does not impose a limit on the number of displays. An ultrawide monitor counts as a single display and the wallpaper fills the full width with the vanishing point centered on the panel.
Recommended wallpaper pairings
The most useful dual-monitor setups pair one calm wallpaper with one more expressive one. Here are pairings that work well across common use cases.
Work and reference (programmer, writer, analyst)
Primary screen: Starfield at minimum speed. It is dark, nearly imperceptible in motion, and does not compete with text. The slow star drift becomes invisible during focus work through visual habituation within a few minutes. Secondary screen: Hue Drift or Planet System. Both are free, both are calm enough to live on a monitor you glance at for reference material. Hue Drift adds a touch of color warmth to an otherwise monochrome setup. Planet System adds gentle orbital motion you will notice when you look over and forget when you look away.
Work and gaming (weekday productivity, weekend games)
Primary screen: Constellations or Starfield. Secondary screen (gaming monitor): Wormhole or Binary Black Holes. The secondary wallpaper is only visible when the gaming monitor is idle. During gaming, the game itself covers the wallpaper and Gloomia pauses rendering on that display, so there is no performance penalty. When you are working, the Wormhole on the secondary screen adds character without demanding attention.
Creative work (designer, illustrator, video editor)
Primary screen: Hue Drift at very low speed on a dark theme. The soft color shift creates a pleasant ambient environment without imposing any particular hue on color perception. Secondary screen: Nebula Drift or Aurora Flow. These are visually richer and suit a secondary display where the reference or preview panel lives. Aurora Flow is particularly well suited if you work to music; its audio reactivity adds subtle life to the edges of your peripheral vision without pulling focus.
Streaming and content creation
Primary screen (game or content): Starfield or nothing visible under the app. Secondary screen (chat, alerts, monitoring): Galaxy Spiral or Nebula Drift. Both look impressive in the few seconds between when you glance at the secondary monitor on camera and when content covers the screen. They also read well in stream overlays that include a monitor-preview window.
Audio reactivity across two monitors
Each display's wallpaper has its own audio reactivity setting, independent of the other. The most common configuration is to enable audio reactivity on a secondary or ambient display while leaving the primary screen static. This means the music-reactive Aurora Flow or Spectrum Bars pulses with your tracks on the secondary monitor while the calm Starfield on the primary screen never changes in response to audio. You get the live feel on the side and the focused environment in the center.
If you prefer both screens to react to audio, both can. A common pairing is Spectrum Bars on one screen and Radial Pulse on the other - the same audio source drives both, visualized in different geometries. With two audio-reactive wallpapers at once, both are reading the same system audio stream, so there is no conflict between them. The CPU overhead is minimal since audio analysis runs once regardless of how many wallpapers are subscribed.
GPU usage and performance
Running two wallpapers does not simply double GPU usage. Gloomia pauses rendering on any display that is fully covered by application windows. On a typical programming setup where the primary monitor is always filled with an editor and a terminal, the primary wallpaper draws almost no GPU cycles for most of the day. Only the secondary display, which may show more of the wallpaper during browser sessions or chat, contributes meaningful GPU draw.
For the calmest wallpapers, Starfield, Hue Drift, Planet System, Constellations, the total GPU draw from both wallpapers together tends to stay under 3 percent on modern hardware even when both are fully visible. For the heavier wallpapers on the secondary screen, Binary Black Holes and Wormhole, GPU draw can reach 5 to 10 percent when fully visible on the secondary monitor. Setting the secondary wallpaper's speed to 0.2 or 0.3 cuts this by roughly half.
During exclusive fullscreen gaming, Gloomia pauses rendering on the gaming display entirely. The secondary display continues rendering its wallpaper on a separate thread, but this does not compete with the GPU time claimed by the game's renderer in the same way. In practice, a calm secondary wallpaper like Starfield causes no measurable FPS impact during gaming.
Setting up an ultrawide primary with a standard secondary
An ultrawide monitor counts as a single display in Gloomia. The wallpaper fills the entire 3440x1440 or 5120x2160 panel. For wallpapers with a directional element, like Starfield's vanishing point or Wormhole's tunnel, Gloomia centers the anchor point on the display by default. You can reposition it in settings if the natural center of the ultrawide does not line up with how you use the panel.
A typical ultrawide-plus-secondary setup runs a very calm wallpaper on the wide primary - Starfield or Hue Drift work particularly well because they fill a wide canvas without any awkward stretching - and a more expressive wallpaper on the secondary. The secondary monitor in this configuration is often a portrait-oriented monitor to the side; Galaxy Spiral and Nebula Drift handle portrait orientation without issues since they fill the frame regardless of aspect ratio.
Tips for getting the pairing right
A few things to keep in mind when setting up your dual-monitor wallpaper configuration:
- Start slower than you think you should. The instinct is to set the secondary wallpaper at a dramatic speed to appreciate it. After 20 minutes you will find it distracting. Start at 0.2 to 0.3, live with it for a day, then increase if it feels too subtle.
- Match color temperature across screens. A warm-toned wallpaper on one screen and a cold-blue one on the other creates a visual imbalance that can feel unsettling after a few hours. Choose wallpapers from similar palettes, or use one of Gloomia's dark-theme settings across both to keep the overall tone consistent.
- Use the free wallpapers to test your layout. Starfield, Planet System, and Hue Drift are available at no cost. Test your per-display configuration with those before deciding whether the Pro wallpapers are worth adding. Many people find that Starfield on primary and Hue Drift on secondary is the ideal pairing and never need to go further.
- Turn off audio reactivity on the primary during calls. If you use audio reactivity, a wallpaper that pulses with your microphone input can be visible to participants in a screen share. Disable audio reactivity on the shared display before presenting or mute the audio input in Gloomia's settings.
- Check per-display settings after resolution changes. If you change a monitor's resolution, scaling factor, or swap cables, Gloomia may reassign display IDs. Open the app and confirm each display's assignment before starting a work session.
Which wallpapers are free, which require Pro
Three wallpapers are free and run without an account: Starfield, Planet System, and Hue Drift. These three cover the most common dual-monitor configurations - particularly the calm-primary use case. Gloomia Pro unlocks the rest of the library, which includes the dramatic space wallpapers most suited to a secondary display: Galaxy Spiral, Nebula Drift, Wormhole, Binary Black Holes, and the audio-reactive category including Aurora Flow and Spectrum Bars.
If you are setting up a dual-monitor configuration for the first time, the free tier is a good way to test whether a live wallpaper setup suits your workflow before looking at Pro pricing. The setup guide at how to set up live wallpapers covers the installation process and initial configuration. The full wallpaper library previews every option before you commit.

Frequently asked questions
Can Gloomia run a different wallpaper on each monitor?
Yes. Gloomia assigns wallpapers per display, with independent speed, color, and audio reactivity settings for each screen. Changes take effect immediately and are saved per-display across restarts.
Does running two live wallpapers use twice the GPU?
No. Gloomia pauses rendering on any display that is fully covered by app windows. On a typical work setup where the primary is always covered, only the secondary display draws GPU cycles. Two calm wallpapers together stay under 3 percent GPU on modern hardware.
What is the best pairing for a work and gaming dual-monitor setup?
Starfield or Constellations on the work monitor, Wormhole or Binary Black Holes on the gaming display. During gaming in exclusive fullscreen, Gloomia pauses the game monitor's wallpaper entirely so there is no performance impact.
Can audio reactivity be different on each monitor?
Yes. Each display's wallpaper has its own audio reactivity toggle and sensitivity. The most common setup is to enable it on the secondary screen only, keeping the primary screen calm while the secondary reacts to music.
Does Gloomia work with ultrawide monitors?
Yes. Ultrawide panels count as a single display and the wallpaper fills the full width. Directional wallpapers like Starfield center their vanishing point on the display, and this can be repositioned in settings.
Do secondary wallpapers affect gaming FPS?
Minimal impact. In exclusive fullscreen, the game monitor's wallpaper is paused entirely. The secondary display continues on a separate thread without competing directly with the game's GPU workload. A calm secondary wallpaper like Starfield causes no measurable FPS loss.
