Luminark v1.1.16

What's New in Luminark v1.1.16:

• Mouse Responsiveness & Jitter Elimination:

• Isolated Tray Mouse Hook: Moved the system tray scroll hook to a dedicated, high-priority background thread with its own message pump. Mouse hook callbacks now return instantly in nanoseconds, completely eliminating cursor stutter or jitter during normal PC usage.
• Asynchronous Hardware I2C Queries: Offloaded physical monitor enumeration and DDC/CI queries to background tasks so hardware display scans during USB/device changes never block the UI thread.
• Removed Synthetic Mouse Events: Eliminated zero-delta mouse nudge events from the keep-awake service, ensuring smooth, uninterrupted cursor tracking for high-polling-rate mice.
• Tray Scroll Toggle Setting: Added a toggle switch in Settings to enable or disable mouse wheel brightness adjustments over the system tray icon.

Luminark v1.1.15

What's New in Luminark v1.1.15:

• Runtime Memory Reduction & Performance Optimization:

• Working Set Trimming: Resolved an issue where idle background memory could reach ~150-200 MB. Re-implemented an intelligent working set trim combining full Gen2 GC, LOH compaction, and Win32 process working set trimming, bringing idle tray memory down to ~15-30 MB.
• Startup Buffer Cleanup: Automatically sheds temporary XAML compilation, DirectX buffers, and monitor enumeration allocations 3 seconds after launching minimized to the tray.
• Periodic Idle Maintenance: Added background idle memory maintenance every 10 minutes when all windows are closed, ensuring memory remains consistently lean over multi-day runtimes.
• .NET 8 DATAS Enabled: Activated Dynamic Adaptation to Application Sizes (DATAS) garbage collection, tuning heap sizes dynamically to minimize memory footprint.

Luminark v1.1.14

What's New in Luminark v1.1.14:

• Monitor Video Input Switching & Detection Fixes:

• Fixed phantom inputs: Stopped populating unverified standard inputs (e.g. VGA, DVI, extra HDMI ports). The app now accurately respects your monitor's hardware DDC/CI capabilities (VCP 0x60) to show only physical ports.
• Fixed input switch cancellation: Closing or clicking outside the quick controls tray flyout no longer aborts active input switches.
• Added "Switch Now" button: Added an immediate execution button and Enter key shortcut to switch inputs instantly without waiting for the countdown timer.
• Resilient DDC/CI communication: Added automatic handle reacquisition, retries, and high-byte preservation to ensure input switch commands reach the monitor hardware reliably.
• Background live input synchronization: Active input status is refreshed when opening the tray flyout, remaining synchronized even when inputs are changed using the monitor's physical OSD buttons.
• Custom input management: Added custom port code addition and input removal directly from the Main Dashboard settings.

Luminark v1.1.13

What's New in Luminark v1.1.13:

• Memory & Performance Optimization:

• Eliminated artificial working set ballooning and forced Gen2 GC cycles, establishing smooth and stable memory utilization.
• Resolved an unmanaged handle and background thread leak in SettingsService.
• Fixed WMI COM object leaks by deterministically disposing all ManagementObject query instances.
• Cleaned up static SystemEvents event subscriptions in ThemeService to prevent memory leaks on exit.
• Properly released native Win32 GDI icon handles on exit.

• Background Hook & Polling Efficiency:

• Refactored TrayScrollHook: Eliminated global mouse movement processing across Windows, saving millions of marshal operations and reducing background CPU usage to 0%.
• Refactored NightLightService into a purely event-driven model without polling timeouts, preventing unnecessary CPU and thread wakeups.
• Consolidated Keep-Awake timers, pausing high-frequency ticks when sleep prevention is set to Forever.
• Increased schedule evaluation interval to 30s for minimal idle impact.

• Security & Reliability Enhancements:

• Added startup safety recovery for Windows Console Lock Display Timeout (VIDEOCONLOCK) to ensure lock screen timeout is never stuck at 1s after an abnormal termination.
• Added log file rotation capped at 5 MB in App.Log to prevent unbounded disk usage.

Luminark v1.1.12

Full Changelog: v1.1.11...v1.1.12

Luminark v1.1.11

What's New in Luminark v1.1.11:

• Screen Off & Keep-Awake on Lock:

• Added "Lock & Screen Off" action and global hotkey (Win+J).
• Automatically powers down internal laptop and external displays natively without putting the PC to sleep.
• Windows 11 Modern Standby (S0) laptops stay 100% awake with network and background tasks running.
• Touching any key or mouse instantly wakes the screen at full normal brightness to unlock.

• External Monitor Video Input Switching:

• Switch monitor inputs (DisplayPort, HDMI, USB-C) directly from the flyout or Main Window via DDC/CI.
• Assign custom friendly names (e.g. Work PC, Gaming Rig) and filter visible ports.
• Active signal indicators (✔) show connected video feeds.

• Multi-Host Display Retention:

• Retains displays switched to other computers as "Inactive", allowing 1-click switching back.

• Clean Startup & Reliability:

• Starts cleanly minimized to the system tray at Windows boot without popup windows.
• Self-contained package with zero external .NET dependencies required.
• Improved Night Light and theme scheduling synchronization.

Luminark v1.1.10

What's Changed in v1.1.10

Fixed

• Eliminate Modern Standby Sleep Trigger in 'Lock & Screen Off':
  • Identified root cause of instant sleep: On Windows 10/11 laptops with S0 Modern Standby, Windows intercepts any \SC_MONITORPOWER (2)\ system command as a manual \SleepButton\ press, forcing the Intel/AMD SoC into S0ix Modern Standby sleep (suspending Wi-Fi to D3 and pausing CPU/apps).
  • When Prevent Sleep is active, Luminark now **never sends \SC_MONITORPOWER**.
  • Hardware Display Standby: External monitors are powered off directly via VESA DDC/CI hardware standby (\VCP 0xD6 = 4), bypassing Windows OS power messages entirely.
  • Internal Display Dimming: Internal laptop displays are dimmed to 0% brightness via WMI when locking, and restored to the previous brightness level upon unlocking.
  • Persistent Display Pipeline: Retains \ES_DISPLAY_REQUIRED\ and \PowerRequestDisplayRequired\ in the kernel so Windows never signals the hardware SoC to enter S0ix sleep.
  • The laptop remains 100% active, network stays connected, and downloads/tasks continue without interruption while screens are dark and workstation is locked.

Full Changelog: v1.1.9...v1.1.10

Luminark v1.1.9

What's Changed in v1.1.9

Fixed

• Keep Laptop Awake During 'Lock & Screen Off' on S0 Modern Standby:
  • Resolved an issue on modern Windows laptops (S0 Low Power Idle / Connected Standby) where pressing 'Lock & Screen Off' or turning off monitors caused Windows to enter Modern Standby sleep despite 'Never sleep when plugged in' and 'Prevent sleep: Forever'.
  • Windows Away Mode Integration: Registered \PowerRequestAwayModeRequired\ via Kernel Power Request APIs and \ES_AWAYMODE_REQUIRED\ via \SetThreadExecutionState. Away Mode ensures the system, CPU, disk, network, and desktop applications run at 100% capacity while screens and audio are powered down.
  • Independent ThreadPool Heartbeat Timer: Added a dedicated \System.Threading.Timer\ running on the thread pool to reaffirm kernel power requests every 30 seconds, preventing Windows from suspending keep-alive state when the desktop switches to \LogonUI\ (lock screen).
  • VESA DDC/CI Hardware Standby: External monitors are explicitly signaled to enter standby (\VCP 0xD6 = 4) and automatically awakened (\VCP 0xD6 = 1) upon session unlock.
  • Targeted Monitor Power Commands: Avoided shell-wide \HWND_BROADCAST\ sleep triggers by directing display power-down commands to the application window.

Full Changelog: v1.1.8...v1.1.9

Luminark v1.1.8

What's New in Luminark v1.1.8:

• Prevent Unminimized Startup at Windows Boot: Resolved an issue where secondary or delayed startup triggers caused the main window to unexpectedly restore and pop up on screen at login.
• Guarded Single-Instance Activation: Secondary launches with --minimized (or packaged StartupTask) now exit quietly and never activate the running background tray instance.
• Autostart Consolidation & Cleanup: Standardized autostart strictly to the Windows Run registry key and added automatic cleanup routines for duplicate shortcuts in the Startup folder.

Luminark v1.1.7

What's New in Luminark v1.1.7:

• Video Input Sources Customization: Manage, rename, and filter monitor inputs (HDMI, DP, USB-C) for the quick controls dropdown.
• Active Signal Indicators: Green checkmarks next to inputs reporting active connected signals.
• Inactive Monitor Retention: Retains displays switched to other devices/PCs so you can easily switch them back.
• Configurable Hotkey: Press Win+J to instantly lock workstation and turn off displays while keeping the PC awake.
• Positioning Fix: Multi-monitor and DPI-aware positioning guarantees the quick controls flyout is always fully visible.
