+# LED Matrix Web Interface V2 - Enhanced Summary
+
+## Overview
+The enhanced LED Matrix Web Interface V2 now includes comprehensive configuration options, improved display preview, CPU utilization monitoring, and all features from the original web interface while maintaining a modern, user-friendly design.
+
+## Key Enhancements
+
+### 1. Complete LED Matrix Configuration Options
+- **Hardware Settings**: All LED Matrix hardware options are now configurable through the web UI
+  - Rows, Columns, Chain Length, Parallel chains

+  - GPIO Slowdown, Scan Mode
+  - PWM Bits, PWM Dither Bits, PWM LSB Nanoseconds
+  - Limit Refresh Rate, Hardware Pulsing, Inverse Colors
+  - Show Refresh Rate, Short Date Format options
+
+### 2. Enhanced System Monitoring
