Fix Tv Overscan

# X11 TV Overscan Fixer Slider (v1.2)

An automated graphical slider utility designed to easily fix television overscan borders on Linux systems using the X11 display server.

This tool is optimized for setups where open-source graphics drivers no longer provide native overscan/underscan percentage configuration settings within the desktop display menus.

### 💾 Quick Installation
Download the pre-compiled `tv-overscan-fixer.deb` file. Double-click to open it with your graphical package installer (like Gdebi), click **Install Package**, and launch "TV Overscan Fine-Tuner" from your system application menu. Built with AI assistance.
