Many users encounter issues where their computer fails to properly recognize a monitor after connection, showing it only as a "Generic PnP Monitor" or even resulting in no display output at all—seriously affecting the user experience.

This article will analyze the common causes of monitor detection failure and provide practical solutions to help you quickly restore normal display functionality.

1. Common Symptoms of Monitor Detection Issues

Monitor shows "No Signal", black screen, or flickering
In Device Manager, the monitor is listed as "Generic PnP Monitor"
Screen resolution cannot be adjusted or displays incorrectly
Extended or mirrored display functions fail

2. Common Causes of Display Problems

Missing or uninstalled dedicated monitor driver
Outdated or incompatible graphics card driver
Driver conflicts caused by system updates
Loose hardware connections or damaged ports
Monitor hardware issues or faulty signal cables

3. Practical Methods to Fix Monitor Detection Problems

Method 1: Check Hardware Connections

Ensure the monitor signal cable (HDMI, DP, VGA, etc.) is firmly connected; try unplugging and reconnecting it.

Try using a different signal cable or port to rule out hardware issues.

Test with another monitor or PC to confirm whether the monitor is functioning properly.

Method 2: Update Graphics Card Driver

Since monitor detection depends heavily on the GPU driver, outdated or faulty drivers often cause these issues. Driver Talent is recommended to use, which can automatically detect and update drivers. This saves time and helps prevent downloading incorrect or incompatible drivers.

Download Driver Talent

Download and install the latest version of Driver Talent, then launch the program and click "Scan".
After scanning, the software will show outdated or missing drivers. Locate the graphics driver in the list and click "Update".

After the update is complete, restart your PC to ensure the new driver takes effect.

Method 3: Update Monitor Driver via Device Manager

Open Device Manager, locate "Generic PnP Monitor" under the "Monitors" section.

Right-click and choose "Update driver", then select "Search automatically for drivers".

If no suitable driver is found, visit the monitor manufacturer's website to manually download and install the correct driver.

If no dedicated driver is available, you can try uninstalling Generic PnP Monitor, then restart your computer—Windows will automatically reinstall the driver.

Method 4: Adjust Display Settings

Go to Display Settings and check whether multiple monitors are detected correctly.
Adjust resolution and refresh rate to avoid display issues caused by improper settings.
