EyeCALIBUR+
Bypass Windows monitor limits & unlock advanced GPU control.
An ultra-lightweight Windows tool (<20MB) to talk natively to your GPU driver API. Adjust brightness (0-100%) and blue light independently per screen, and globally unlock color curves, contrast, and saturation up to 200%. 0% telemetry, fully local.
Hi Product Hunt! 👋
I'm Elay, the developer behind EyeCALIBUR+. As an electronic engineer and programmer, I spend countless hours staring at multi-monitor setups. I grew completely frustrated by the rigid, native display restrictions built into Windows and graphics drivers—forcing poor scaling, high minimum brightness levels, and messy multi-screen management.
So, I built a solution from scratch.
EyeCALIBUR+ is an ultra-lightweight Windows utility (<20MB) engineered to talk directly to your native Windows and GPU driver APIs. No background bloat, no invasive installation.
🖥️ What makes it different?
Independent Screen Filtering: Map and adjust screen brightness (from a true 0% to 100%) and blue light filters per display independently.
Advanced GPU Control: Unlock the color ramp and curve profiles of your GPU globally, boosting RGB channels, contrast, and saturation up to 200% to eliminate washed-out colors.
Hotkey-Driven Efficiency: Change parameters instantly on your active screen based on where your mouse cursor lives.
Privacy-First Architecture: Absolute 0% Telemetry. Your configuration profiles and license data stay 100% encrypted right on your local machine.
