Uninstalled Razer Synapse and now it has no output to the monitor

Troubleshooting Monitor Connectivity Issues After Uninstalling Razer Synapse

Many users encounter unexpected technical issues following software uninstallation, especially with specialized peripherals and their associated drivers. Recently, a user experienced a complete loss of display output after removing Razer Synapse from their new computer setup. This article explores potential causes and solutions for such problems, aiming to assist users in resolving monitor connectivity issues efficiently without the need for professional repair services.

Understanding the Issue

In this scenario, the user had installed Razer Synapse primarily to disable RGB lighting on a budget keyboard. After uninstalling the software, their monitor stopped receiving a signal — even when switching to alternative connection methods like HDMI or connecting directly to the motherboard’s video output. The system appeared stable until Synapse was removed, indicating a possible dependency or conflict created by the software.

Common Causes

1. Graphics Driver Conflicts or Corruption:
   Uninstalling peripheral software can sometimes disrupt associated drivers, especially if the software managed or interacted with the GPU’s display output.

2. Faulty Default Display Settings:
   Removing software that dynamically manages peripheral settings could inadvertently reset or disable display configurations.

3. Hardware Detection Issues:
   Certain software uninstalls might interfere with hardware detection, causing the system to fail to recognize the graphics card or monitor connections.

Suggested Troubleshooting Steps

1. Check Physical Connections:
   Ensure all video cables are securely connected. Try different cables or ports to rule out hardware issues.

2. Verify Video Output Settings:
   Go into your BIOS or UEFI firmware settings to confirm the primary display output is correctly configured. If you’re using a dedicated GPU, ensure it’s set as the primary display device.

3. Reinstall or Update Graphics Drivers:
   Uninstall your current GPU drivers using a tool like Display Driver Uninstaller (DDU), then download the latest drivers directly from your GPU manufacturer’s website (NVIDIA, AMD, or Intel). Reinstall these drivers to restore display functionality.

4. Perform a System Reset of Display Settings:
   Boot into Safe Mode, which loads minimal drivers and settings. Check if the monitor displays correctly. If it does, reboot normally and reconfigure display settings.

5. Restore System to a Previous Point:
   If the system creation of restore points is enabled, consider reverting to a prior state before the uninstallation of Razer Synapse.

6. Check for Hardware Failures:
   Test the monitor with another
