Multi-Monitor Gaming Should Be Easy.Now It Is.

LumaEdge creates immersive multi-monitor lighting without spanning, stretching, or rendering your game across every display. It also turns unused black-bar space into reactive Cinema ambience.

The Screen Does Not Have to End There

Stretch a game's atmosphere across your whole desk, or turn unwanted black bars into part of the film. LumaEdge adapts without changing the content itself.

Gaming

Make Every Monitor Part of the Game

LumaEdge samples the edges of your main display and paints matching reactive gradients across the monitors around it.

  • Multi-monitor ambient color in real time
  • Per-monitor direction and gradient controls
  • Adaptive color shaping and shareable profiles
Cinema

Turn Black Bars Into Atmosphere

Fill letterboxes, pillarboxes, and windowboxes with gradients that feel like the movie continues beyond its frame.

  • Content detection for fast positioning
  • Cinema Depth and subtitle protection
  • Made for ultrawides, videos, and films

It Started With Glow.
It Did Not Stop There.

The original reactive gradients are still the heart of LumaEdge. Now they are joined by a full audio visualizer, shaped effects, custom masks, flexible layouts, and a lot more room to make the result yours.

Give Your Music
Some Screen Time.

Turn the sound playing on your PC into a living field of color. Keep it clean and smooth, break it into segments, add falling peaks, or tune it until it behaves exactly the way you want.

  • Adjustable frequency range, response, bar width, and direction
  • Segmented bars, falling peaks, and custom peak color
  • Run it full-screen or combine it with masks and other effects

Masks + Funbox

Shape The Effect.
Then Get Weird With It.

Masks turn Luma's color into something with a silhouette, rhythm, and personality. Use one of the included designs, import your own, flip it to suit the display, then place reactive lighting or the visualizer behind it.

  • Sixteen included patterns, from subtle geometry to a full dragon
  • Custom mask imports with horizontal and vertical flipping
  • Glow shapes, animated gradients, and audio-reactive color
01

Fits Your Desktop

Side-by-side, stacked, portrait, ultrawide, or delightfully strange. Configure each display around the setup you actually own.

02

Control Without Clutter

Switch Settings between horizontal and vertical layouts, use sliders or exact values, and keep large Funbox controls from becoming a scrolling expedition.

03

Save It Your Way

Build profiles for games, films, music, and moods. Bring the controls you use most within reach using configurable hotkeys.

Fantasy to Realism,
LumaEdge Adapts

Stylized worlds, photorealistic landscapes, pixel art. LumaEdge samples your screen edge in real-time and matches whatever you're playing.

Right Display
Everything Included

Deep Control.
Easy When You Want It.

High-Fidelity Color Bands

Detailed sampling preserves the variation across a scene instead of reducing an entire edge to one average color. Unless you want it to!

Built for Every Display Setup

Use one screen or five. Fill letterboxes on a TV, pillarboxes on an ultrawide, or extend a game's color across the monitors around you.

Profiles and Themes

Save different setups, build custom interface themes, and share configurations without rebuilding them by hand.

Make It Yours

Dial in anything from a soft, subtle glow to a bold wall of color. Luma gives you deep control over how every effect looks, feels, and responds.

Content Detection

LumaEdge can recognize letterboxed, pillarboxed, and windowboxed content, then fit its Cinema lighting to the visible picture.

Your Monitors, Your Layout

Left, right, above, below, or somewhere delightfully weird. LumaEdge follows your setup instead of asking your setup to follow LumaEdge.

HDR, Fully Accelerated

LumaEdge handles HDR content through its GPU-accelerated pipeline, keeping your lighting smooth, responsive, and rich with color.

Built to Leave Your FPS Alone

LumaEdge is built to stay out of your game's way, delivering immersive ambience with virtually no noticeable impact on performance.

Ultrawide Without the Black Bars

On a single ultrawide, Luma turns empty pillarboxes around games and video into reactive color. No side monitors required.

No LEDs. No Mystery.

Do I need multiple monitors?

No. LumaEdge supports multi-monitor setups, but Cinema Mode and its positioning tools can work entirely on one display.

Does LumaEdge upload my screen?

No. Screen sampling and gradient rendering happen locally on your PC. LumaEdge does not need to send your content anywhere.

Does it work with every fullscreen mode?

LumaEdge is designed for windowed and borderless fullscreen content. Exclusive fullscreen behavior can vary between games.

Dynamic Frame Capture

LumaEdge scales its activity with what is happening on screen. Calm scenes stay efficient, while fast scenes get the updates they need.

Make the Screen
Feel Bigger

Games, films, ultrawides, or a desk full of monitors. Give every edge somewhere to go.
