RTXFixer 2.2 – Black Screen Handshake Utility

Does your monitor stay black when waking your PC?

If you own an NVIDIA RTX 40‑series or 50‑series GPU and experience intermittent black screens, “No Signal”, or failed wake‑from‑sleep events, RTXFixer 2.2 is designed to help.

RTXFixer is a lightweight background utility that safely forces Windows to re‑apply valid display modes.
This triggers the GPU and monitor to re‑negotiate their DisplayPort / HDMI handshake, often restoring video output instantly — without rebooting, logging out, or restarting GPU drivers.

What’s New in Version 2.2

• 🧠 Nuclear Reset Fallback
  When the standard resolution‑cycle fails (e.g. the GPU driver is completely hung), RTXFixer now automatically performs a full display‑adapter reset (CDS_RESET) and retries the handshake — breaking through even deeply locked‑up states.

• ⚡ Always Responsive
  Display resets now run on a background thread. The tray menu stays fully interactive, even during a fix.

• 🎯 Smarter Single‑Monitor Handling
  On single‑monitor systems, the tool automatically switches to a full reset — no more silent “no‑op” when targeting secondary displays.

• 💾 Resolution Preservation
  Instead of forcing a “maximum native” mode, RTXFixer now captures your exact configured resolution, refresh rate, and monitor placement and restores them precisely after the handshake.

• ⌨ Easier Panic Hotkey
  The hotkey has been changed to Ctrl + Shift + F12 (no more Alt). Faster to press when your screen is black.

• 📋 Enhanced Logging
  Logs now include millisecond timestamps and thread IDs, making it easier to diagnose what happened.

Works With

• NVIDIA RTX 40 Series (4060, 4070, 4080, 4090, etc.)
• NVIDIA RTX 50 Series (5060, 5070, 5080, 5090, etc.)
• Windows 10 & Windows 11
• HDMI and DisplayPort monitors
• Single‑ and multi‑monitor setups

Features

• ✔ Reliable Handshake Reset + Nuclear Fallback
  Captures your current display settings (resolution, refresh, position) → drops to 1024×768 to break the handshake → restores your exact original settings. If the drop fails, a full adapter reset is triggered automatically and the handshake is retried.

• ✔ Smart Display Targeting
  Choose from the tray menu: Reset Secondary Only (default, safest), Reset Primary Only, or Reset ALL Displays. Single‑monitor systems are handled intelligently — no skipped resets.

• ✔ Automatic Resume Protection
  Detects system wake‑from‑sleep and only fires if no active display paths are found, preventing unnecessary flicker.

• ✔ Fully Responsive Tray App
  No window, no taskbar clutter. Resets run in the background — the tray icon and menu never freeze.

• ✔ Cooldown & Concurrency Safety
  Prevents retry storms (hotkey spam, overlapping wake events) with an in‑memory cooldown — no registry writes.

• ✔ Detailed Logging
  Every action, return code, and step is written to %LocalAppData%\RTXFixer\rtx_fixer.log.

• ✔ Audio Feedback (Screen‑Independent)
  • 2 low beeps = Fix started
  • 1 high beep = Success
  • 3 low beeps = Failed or suppressed (cooldown / no valid target)

Hotkey

Ctrl + Shift + F12
Triggers the fix using the current target mode (set via tray menu).
(Previously Ctrl+Alt+Shift+F12 — now even easier to press during a black‑screen emergency.)

How to Use

1. Download and extract the ZIP file (do not run directly from inside the archive).
2. Run RTXFixer.exe — the app starts silently in your system tray.
3. Manual fix:
   • Press Ctrl + Shift + F12, or
   • Right‑click the tray icon → Force Handshake Fix
4. Advanced targeting: right‑click tray icon → select Reset Secondary Only, Reset Primary Only, or Reset ALL Displays.

Optional: Run on Startup (Recommended)

1. Right‑click RTXFixer.exe → Create shortcut
2. Press Win + R, type shell:startup and press Enter
3. Move the shortcut into that folder

RTXFixer will now launch silently at login.

Emergency Backup (Windows Shortcut)

If RTXFixer cannot restore your display:
Win + Ctrl + Shift + B
(Restarts the graphics driver — more disruptive, but effective)

RTXFixer is recommended first because it is gentler and preserves open apps.

What This Tool Does NOT Do

RTXFixer does not:

• Install, modify, or replace GPU drivers
• Permanently change display settings
• Overclock hardware
• Modify system files beyond safe Windows APIs

RTXFixer only re‑applies existing, valid display modes.

⚠️ IMPORTANT: What This Does NOT Fix

This tool is designed for display handshake bugs only.

It will NOT fix:

❌ Physically faulty HDMI / DisplayPort cables
❌ Dead monitors or GPUs
❌ System crashes or freezes (BSOD)
❌ PCs that are fully unresponsive to input

If your keyboard LEDs don’t respond, this tool cannot help.
