Display VCP

A KDE system tray application which provides a Virtual Control Panel (VCP) to control display features like brightness, contrast, etc. and other manufacturer-specific features.

Warning

Use this work at your own risk.

This project is neither robust nor compatible with display models other than what's hardcoded.
