v1.3.0 - HDR Support, Rotation Control & Enhanced Display Engine

🎉 Release Highlights

This release brings significant improvements to display management with HDR support, screen rotation control, and a completely rewritten display configuration engine for unprecedented reliability in multi-monitor setups. Perfect for users with HDR-capable displays, portrait monitors, or complex multi-monitor configurations.

✨ What's New

🎨 HDR (High Dynamic Range) Support

• Enable/Disable HDR per monitor - Control HDR settings for each display independently
• Automatic HDR capability detection - The application automatically detects which monitors support HDR
• Per-profile HDR configuration - Save different HDR settings for different usage scenarios (gaming, content creation, etc.)
• HDR status preservation - HDR settings are reliably applied when switching profiles

🔄 Screen Rotation Control

• Full orientation support - Configure screen rotation for each monitor (0°, 90°, 180°, 270°)
• Perfect for portrait setups - Easily manage monitors in portrait orientation
• Multi-orientation profiles - Create profiles with different monitor orientations (e.g., one landscape, one portrait)
• Reliable rotation application - Rotation is applied atomically with other display settings

⚙️ Staged Application Mode

• Two-phase profile application - New optional mode that applies complex settings in phases for enhanced stability
• Improved reliability for complex setups - Dramatically reduces failures when switching profiles with HDR, high refresh rates, or multiple displays
• Configurable pause duration - Adjust the delay between phases (1-5000ms) to optimize for your specific hardware
• Smart activation - Only used for multi-monitor profiles when enabled in settings
• User-controlled - Easily toggle on/off in Settings > Display Configuration

🔧 Enhanced Display Configuration Engine

• Complete rewrite using modern Windows APIs - Replaced legacy ChangeDisplaySettingsEx with atomic SetDisplayConfig API
• Atomic topology application - All display settings (resolution, refresh rate, position, primary, HDR, rotation, enable/disable) are applied in a single operation
• Drastically improved reliability - Eliminates iterative setting application failures that plagued multi-monitor setups
• Better error handling - More robust detection and recovery from display configuration issues
• Future-proof architecture - Built on modern Windows Display Configuration API for better compatibility with future Windows versions

🔍 Technical Details

Updated Components

• DisplayConfigHelper - Complete rewrite using Windows Display Configuration API (SetDisplayConfig)

v1.2.0-beta.2 - Enhanced Display Stability & Monitor Management

📋 Overview

This beta release focuses on improving display configuration stability and handling edge cases in multi-monitor setups. The key enhancement is the introduction of automatic rollback functionality that ensures users never get stuck with broken display configurations.

⚠️ Important Installation Note

For the best experience with this beta release:

• Clean installation recommended: Delete the existing %AppData%\DisplayProfileManager folder before running this version
• First run behavior: The application will automatically save your current display settings as a "Default" profile
• Administrator privileges required: The application needs admin rights for DPI scaling changes

✨ New Features

🔄 Automatic Display Topology Rollback

• Automatically reverts to the previous working multi-monitor layout if topology changes fail
• Specifically handles failures when enabling/disabling monitors or changing monitor arrangements
• Shows informative notifications explaining what went wrong and confirming the successful rollback
• Prevents users from being stuck with non-functional monitor configurations
• Captures and preserves the original display topology before making layout changes
• Note: This rollback applies to monitor layout/topology only, not to resolution, refresh rate, scaling, or primary display settings

👁️ Visual Monitor Status Indicators

• Disabled monitors now display with distinct visual styling in the profile details panel:
  • Yellow-tinted background for immediate recognition
  • "⚠ DISABLED MONITOR" warning label
  • Reduced opacity to differentiate from active monitors
• Enabled monitors show with a subtle border for visual consistency

🐛 Bug Fixes

Display Management

• Fixed unspecified monitor handling: Monitors not included in a profile are now properly disabled when applying that profile
• Fixed inactive monitor positioning: Skip inactive monitors during display layout positioning to avoid configuration errors
• Added safety checks: Prevent array access errors with bounds checking for mode info indices

User Interface

• Fixed profile editor scrolling: Removed nested ScrollViewer that was preventing mouse wheel scrolling in the Profile Edit Window
• Improved content accessibility: Users can now smoothly scroll through all profile settings without manually dragging the scrollbar

📖 User Guide

Getting Started with Display Profile Manager

1. Understanding Monitor Management

Important: Manual monitor adding has been intentionally removed to make the program more controllable and simpler. Follow this workflow:

1. Connect and enable all monitors you want to use in Windows Display Settings
2. Arrange their positions in Windows Display Settings (this app doesn't support layout editing yet)
3. Click "Detect Current" in the app to detect all connected/enabled monitors
4. Configure the profile by:
   • Enabling/disabling specific monitors
   • Adjusting resolution, refresh rate, and DPI scaling
   • Setting audio devices if needed

2. Creating Your First Profile

1. Open the main window
2. Create a new profile: Click "Add Profile"
3. Capture current setup: Click "Detect Current" to capture your current display configuration
4. Configure displays:
   • Enable/disable monitors using the checkboxes
   • Set resolution and refresh rate for each monitor
   • Adjust DPI scaling (100%, 125%, 150%, etc.)
   • Choose which monitor should be primary
5. Configure audio (optional):
   • Select default playback device (speakers, headphones)
   • Select default communication device (microphone)
   • Check the boxes to apply these settings with the profile
6. Set a hotkey (optional): Click in the hotkey field and press your desired key combination
7. Save the profile: Give it a descriptive name and click "Save"

3. Switching Between Profiles

Quick Methods:

• System Tray: Right-click tray icon → "Profiles" → Click on any profile name
• Hotkeys: Press the configured hotkey combination for instant switching
• Main Window: Select a profile and click "Apply Profile"

4. Managing Profiles

• Edit: Select a profile → "Edit" to modify settings
• Duplicate: Create a copy of an existing profile for variations
• Delete: Remove profiles you no longer need
• Import/Export: Backup or share profiles using the File menu

5. Settings Configuration

Access via right-click tray icon → "Settings":

• Start with Windows: Enable automatic startup
• Default Profile: Choose which profile to apply on startup
• Theme: Select Light, Dark, or follow system theme
• Minimize to Tray: Keep running in background when closed

Tips for Best Results

1. Use descriptive names like "Gaming - 144Hz", "Work - Dual Screen", "Presentation - Single Display"
2. Set up hotkeys for frequently used profiles for instant switching
3. Create a "Default" profile that matches your most common setup
4. Use the duplicate feature to create variations of working profiles
