Creators & Pros

Precise calibration.
Export everywhere.

Far beyond the DDC-CI slider — a real per-channel tone curve editor with ICC v2 profile export. Your editing software and your screen, finally aligned.

Monotone cubic spline (Fritsch-Carlson 1980) — 5 control points

✏
Per-channel tone curve editor
Click to add points, drag to adjust, right-click to remove. Fritsch-Carlson 1980 algorithm — guaranteed monotone, zero ringing.
🎨
ICC v2 export — Photoshop, Lightroom, Resolve
ICC v2 profile with D50-adapted sRGB primaries (Bradford) and your custom TRC curves. Import into your tools so display and editing stay consistent.
🔗
Non-destructive composition
Night mode, GPU gamma and warmth compose on top of your curves without ever overwriting them. Enable warm tint without redoing your calibration.
🖥
Automatic identification via EDID
Two-step resolution: GDI driver then EDID registry fallback. Lumina displays "LG ULTRAWIDE", not "Generic PnP Monitor".
📸
Photographers
Calibrate your monitor and export an ICC profile so Lightroom and Photoshop correctly interpret your colors when processing RAW files.
🎬
Videographers & colorists
S-curves on your monitoring panels to verify contrast and roll-off. ICC export aligns DaVinci Resolve and Premiere Pro with your actual display.
🎮
Streamers
Custom curves for accurate game image across both screens. Per-app rules automatically apply your settings as soon as OBS comes to the foreground.

Installation

Windows shows a warning?
That's normal.

Follow these 2 simple steps to install Lumina Control safely.

ℹ️
Windows SmartScreen flags software that doesn't have a code signing certificate — a certificate that costs several hundred euros per year, out of reach for an independent project at €4.80. Lumina Control's source code is available on GitHub: you can review how the application works before installing.

FAQ

Frequently asked questions

Is my monitor compatible?
Lumina Control works with all monitors that support the DDC-CI protocol (the vast majority of modern desktop screens). Make sure DDC-CI is enabled in your monitor's OSD menu. Laptop built-in panels don't support DDC-CI, but Lumina Control controls them via the WMI backend for brightness. For all screens, the tone curve editor and GPU gamma work without DDC-CI.
Can I use it on multiple PCs?
The Pro licence allows installation on 2 machines simultaneously. If you change PC, contact support for a reactivation.
Does it work with HDR?
DDC-CI control is disabled by Windows when HDR is active on a monitor. Lumina Control then uses the GDI32 gamma LUT for tint and gamma adjustments, but DDC-CI brightness won't be available while HDR is on.
Is there a free trial?
No trial at the moment. If the software doesn't work correctly on your configuration within 7 days of purchase, contact support for a full refund.
What's the difference from Windows Night Light?
Windows Night Light is a software overlay that tints the screen orange. Lumina Control acts directly on the monitor firmware via DDC-CI: physical brightness actually decreases, reducing eye strain and power consumption. No overlay, no color degradation.
Does the curve editor work without DDC-CI?
Yes — tone curves and GPU gamma (SetDeviceGammaRamp) go through GDI32 and work on all screens, even without DDC-CI. ICC v2 profile export is also independent of DDC-CI. Only the R/G/B gains in the first tab require an active DDC-CI connection.
Can I import the ICC profile into Photoshop / Lightroom?
Yes. The ICC v2 profile generated by Lumina Control encodes D50-adapted sRGB primaries and your correction curves in the TRC tags. Import it into Photoshop (Edit → Color Settings) or set it as your screen profile in Windows settings so DaVinci Resolve, Lightroom and Premiere Pro recognize it automatically.
