Screen Sync
Screen Sync analyzes the foreground window and drives Chroma lighting to match.
Analysis
Screen Sync watches the foreground window, falling back to full screen. Three models run alongside each other, inferring the salient colors, the on-screen pattern and the active zone of the frame, the part of the picture that holds meaningful content. Together they decide what the lighting should be doing at any given moment.
| Analysis | Output |
|---|---|
| Salient colors | Dominant color plus a contrasting secondary, with vividness and brightness boosted |
| Patterns | Classified on-screen pattern, used to select a matching lighting pattern |
| Active zone | Rectangular region of meaningful content |
Color keeps up with the content. Pattern and active zone describe broader scene structure and settle more slowly, so pattern changes can trail color changes.
What this means for your visuals
Dominant color extraction rewards color identity. Scenes built around a strong dominant color translate cleanly to device lighting. Uniformly desaturated scenes provide less for the extractor to separate.
Color scripting carries through automatically. Palette shifts by act, biome, or threat state extend to the player's devices with no work on your side.
Active zone detection handles borders. Letterboxed cinematics, ultrawide pillarboxing, and similar framing are trimmed, so colors are sampled from the picture rather than the bars.
Screen Sync follows the focused window. Verify how your title behaves in borderless and exclusive fullscreen, and when overlays take focus.
Color treatment
Output colors are intentionally more saturated and brighter than the source image, so that lighting reads well on RGB hardware. A literal match reads as flat on a keyboard, because a display and a lit peripheral are different media. Screen Sync reproduces the overall color character of a scene rather than performing pixel-accurate color matching. Do not expect device lighting to match a specific rendered color value.
Requirements
Screen Sync drives lighting through RzChromatic, which must be at version 2.3.2.0 or newer. On earlier versions no ambient lighting appears.
