RTXFixer 2.1 – 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 2.1 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 2.1

RTXFixer 2.1 is a major internal upgrade focused on reliability, safety, and multi-monitor setups:

• Multi-Monitor Aware
  Safely targets only the affected display instead of disrupting your entire desktop.

• Targeted Reset Modes

  • Reset Secondary display only (default & safest)

  • Reset Primary display only

  • Reset ALL displays (advanced / nuclear option)

• Advanced Tray Menu All reset options are now accessible directly from the system tray — no command-line shortcuts required.

• Safe Resolution Cycling Uses validated, driver-approved display modes instead of forcing unsafe resolutions.

• Persistent Cooldown Protection Prevents repeated resets during boot loops or rapid wake events.

• Detailed Logging Logs every action, resolution, refresh rate, and return code for troubleshooting.

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

• Automatic Protection
  Runs silently in the background and checks for full black-screen states when resuming from sleep.

• Manual Hotkey (“Panic Button”)
  Press Ctrl + Alt + Shift + F12 to force a handshake reset at any time.

• Advanced Target Selection (Tray Menu)
  Choose exactly which display to reset:

  • Secondary only (default)

  • Primary only

  • All displays

• Audio Feedback (Screen-Independent) Beep codes confirm progress even when nothing is visible.

• System Tray Operation Runs minimized with a shield icon — no window clutter.

Audio Codes (Beeps)

• 2 Low Beeps
  Fix sequence started.

• 1 High Beep
  Success — display mode restored.

• 3 Fast Low Beeps
  Fix failed or suppressed (cooldown active or no eligible display detected).

In v2.x the screen may not visibly drop to a low resolution — this is intentional.
The handshake can often be fixed by re-applying validated modes without aggressive flickering.

How to Use

1. Download and extract the ZIP file
   (Do not run directly from inside the archive)

2. Run RTXFixer.exe

3. The app will start silently in your system tray.

Manual Fix

• Press Ctrl + Alt + Shift + F12, or

• Right-click the tray icon → Force Handshake Fix

Advanced Options

• Right-click tray icon → Advanced Targets

  • Reset Secondary Only

  • Reset Primary Only

  • Reset ALL Displays

Optional: Run on Startup (Recommended)

To protect your display automatically every time Windows starts:

1. Right-click RTXFixer.exe → Create shortcut

2. Press Win + R

3. Type shell:startup and press Enter

4. 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.
