Support CoolerLCD.
The driver is free and MIT-licensed, for both Windows and Linux. Donations go toward a Windows code-signing certificate (so the .exe stops triggering SmartScreen warnings), hardware for compatibility testing, and long-term maintenance. Pick whatever's easiest for you.

Where it goes
What support helps with.
Top priority
Code-signing certificate
An EV code-signing cert (≈ $300–500 USD/year) so the Windows .exe ships SmartScreen-clean. No more "Windows protected your PC" — just one click, then run.
Hardware testing
Buying or borrowing compatible cooler LCD units (different sizes, vendors, rebrands) to confirm behavior beyond a single device.
Cross-platform parity
Keeping Windows and Linux drivers in sync as the protocol evolves, plus future macOS / ARM Linux builds.
Documentation
Maintaining install notes, the protocol spec, troubleshooting guides, and the public sites.
Safety
Donation safety.
