Hardware display control,
crafted with simplicity.
Manage brightness, volume, custom resolutions, refresh rates, underscan, and per-display power across all your external monitors and built-in screens. 100% free under the MIT license.
Built for power users. Simple for everyone.
Low-level I2C bus control and window-server integration with zero unnecessary bloat.
Native DDC/CI Protocol Communication
Direct I2C hardware bus control for Apple Silicon (M1/M2/M3/M4) and Intel Macs. Adjust hardware brightness, contrast, volume, input sources, and DPMS sleep over HDMI, DisplayPort, and USB-C.
Discrete Screen Power
Toggle any display ON or OFF independently without waking sleeping monitors or scrambling open windows via SkyLight window-server management and zero-gamma LUT blackout.
Underscan & Overscan Sizing
Compensate for cropped TV or projector bezels with custom 0%–25% hardware letterboxing and VCP geometry scaling.
Native Resolution & ProMotion Control
Switch resolutions, HiDPI 2x Retina modes, and high refresh rates (up to 240Hz+) instantly via a clean native dropdown menu instead of clunky sliders.
Automated Panel Intelligence
Instant mathematical calculation of screen diagonal inches, pixel density (PPI), and aspect ratio with 1-click Display P3 vs sRGB color calibration presets.
Zero Telemetry & 100% Free
No accounts, no background analytics, and no subscription paywalls. MIT licensed, private forever, with a tiny footprint under 20MB of RAM.
Native Cross-Platform Core
Engineered in Swift & AppKit for macOS, with dedicated native backends for Windows 11 (DXVA2) and Linux (ddcutil/X11/Wayland).
Direct side-by-side comparison.
