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.

Windows 10 and 11 Single or Multi-Monitor Runs Locally

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.

  • Per-monitor direction and gradient controls
  • Adaptive color shaping and shareable profiles

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

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
Simple by Design

Three Steps.
Zero Complexity.

01
🎯

Capture

LumaEdge reads narrow sampling regions from the relevant edges of your source display. Processing stays local on your Windows PC.

02
🎨

Process

The sampled colors are shaped, smoothed, and blended into configurable bands that react naturally as the content changes.

03

Project

Borderless overlays extend those colors onto surrounding displays or into the unused space around ultrawide content.

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.

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.

Color Shaping Suite

Tune intensity, saturation, contrast, tint, reach, softness, opacity, adaptive output, and more.

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.

Clicks Pass Through

Keep using the windows, icons, and controls beneath LumaEdge's gradients without turning the lighting off.

Performance Options

Choose broad compatibility, smooth GPU acceleration, or HDR-ready output. Then tune LumaEdge to fit your PC.

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.
