If your USB-C portable monitor isn’t working, check the connection, power supply, drivers, and display settings. These steps can help resolve common issues and get it functioning again.
USB-C portable monitors have become a popular choice for people who need an extra screen for work, gaming, or entertainment. These monitors are convenient because they are lightweight, easy to carry, and require just a single cable to connect and power.
However, if your USB-C portable monitor is not working, it can be frustrating. Don’t worry; this guide will help you understand the possible reasons and solutions to get your monitor back up and running.
Ensure a Secure USB-C Connection:
Double-Check the Connection:
Start by making sure that the USB-C cable is firmly plugged into both your monitor and your device (like a laptop or tablet). Sometimes, the connection can be loose, which might cause the monitor to not work properly.
Try a Different USB-C Cable:
If the connection looks fine but the monitor still isn’t working, the problem might be with the cable. USB-C cables can sometimes wear out or get damaged. If you have another cable, try using it to see if it makes a difference. A damaged or low-quality cable can cause issues like no signal, flickering, or even not powering the monitor at all.
Check if Your Device’s USB-C Port Supports Video Output:
Not all USB-C ports are created equal. Some USB-C ports on devices are only for charging or data transfer and don’t support video output. To check if your device’s USB-C port can send video to the monitor, look for symbols like a small “DP” (for DisplayPort) or a monitor icon near the port. You can also check your device’s manual or specifications online.
Verify the Power Supply:
Make Sure the Monitor is Getting Enough Power:
Some USB-C portable monitors need more power than your device can provide through the USB-C cable alone. In such cases, the monitor might come with a separate power adapter or an additional USB cable for power. Check the monitor’s manual to see if it needs extra power and ensure it’s plugged in properly.
Use the Power Cable Provided by the Manufacturer:
If your monitor came with a specific power cable, it’s best to use that one. Using a third-party power cable might not give the monitor enough power, causing it to not work correctly.
Update Drivers and Software:
Update Your Device’s Graphics Drivers:
Graphics drivers are the software that helps your computer communicate with your monitor. If these drivers are outdated or corrupted, your monitor might not work. Visit your device’s manufacturer website to download and install the latest graphics drivers.
Check for Monitor Firmware Updates:
Some portable monitors have firmware updates that can fix bugs or improve performance. Visit the monitor manufacturer’s website to see if there are any updates available. Follow the instructions on how to update the firmware.
Check and Adjust Display Settings:
Manually Detect the Monitor in Display Settings:
Sometimes, your device might not automatically recognize the monitor. You can manually detect it by going to your device’s display settings. On Windows, you can do this by right-clicking on the desktop, selecting “Display settings,” and then clicking “Detect.” On a Mac, go to “System Preferences,” click “Displays,” and then press the “Detect Displays” button.
Choose the Correct Display Mode:
Once the monitor is detected, make sure the display mode is set correctly. You can choose to extend your display (to use both your device screen and the portable monitor) or duplicate it (to show the same content on both screens). If the monitor is set to “Second Screen Only,” and it’s not working, you won’t see anything on your main screen either.

Test the Monitor on Another Device:
Try Connecting the Monitor to a Different Device:
To rule out any issues with your original device, try connecting the USB-C portable monitor to another device, like a different laptop, tablet, or even a smartphone that supports USB-C video output. If the monitor works on another device, the problem might be with your original device’s USB-C port or settings.
Test with Different USB-C Ports:
If your device has multiple USB-C ports, try connecting the monitor to a different one. Some USB-C ports are designed only for charging or data transfer, and not for video output. Testing with another port can help you figure out if the issue is port-specific.
Common Issues and Solutions:
Monitor Not Turning On:
If your monitor doesn’t power on at all, first check the power connection. Make sure it’s getting enough power, either through the USB-C cable or an additional power source. If your monitor requires extra power, ensure that both the USB-C and power cables are connected properly.
No Signal Detected on the Monitor:
If your monitor powers on but shows a “No Signal” message, the problem could be with the USB-C cable or the port. Try using a different cable or connecting the monitor to another USB-C port on your device. Also, double-check that your device’s USB-C port supports video output.
Flickering or Unstable Display:
If the display on your monitor is flickering or unstable, it could be due to a loose connection, a low-quality cable, or insufficient power. Make sure all cables are securely connected and consider using a different, high-quality USB-C cable. If your monitor requires an external power source, ensure it’s getting enough power.
When to Seek Professional Help?
Persistent Issues:
If you’ve tried all the troubleshooting steps and your monitor is still not working, it might be time to contact professional support. The monitor manufacturer’s customer service team can help you diagnose and fix the problem.
Potential Hardware Fault:
In some cases, the monitor itself might have a hardware fault. If your monitor is still under warranty, you may be eligible for a repair or replacement. Reach out to the manufacturer’s support team to discuss your options.
