The ‘No Signal’ error in Streamlabs OBS can be frustrating, especially when you’re trying to capture gameplay or stream from an external device. This issue can be caused by several factors, including hardware connection problems, incorrect settings, or software conflicts. Fortunately, there are multiple ways to troubleshoot and fix this problem effectively.
Common Causes of the ‘No Signal’ Error
Before diving into solutions, it’s essential to understand what can cause this error:
- Loose or faulty cables – A bad HDMI or USB cable can result in no signal being detected.
- Incorrect input source selection – The wrong video source might be selected in Streamlabs OBS.
- Faulty or outdated drivers – Your capture card or GPU drivers may need updating.
- Conflicting software – Other programs might interfere with Streamlabs OBS, preventing it from receiving the signal.
- Capture card issues – Some capture devices may not work correctly without specific settings adjustments.
Steps to Fix the ‘No Signal’ Error
1. Check All Cable Connections
Start by verifying that all cables are securely connected. If you are using an HDMI cable to capture video from a console, ensure that the cable is functional by testing it with another device.
2. Select the Correct Video Source
In Streamlabs OBS, go to the properties of the capture card source and make sure the correct input source is selected.
- Open Streamlabs OBS.
- Right-click on the capture card source.
- Click on “Properties.”
- Under “Device,” select the correct capture card.
- Check the “Resolution/FPS Type” settings to ensure they match your device.
3. Restart Your Devices
Sometimes, simply restarting your computer, capture card, and external device (such as a gaming console) can resolve the issue. A reboot can refresh hardware connections and software settings.
4. Ensure Your Capture Card is Detected
Check whether your capture card is properly detected by the system:
- On Windows, open Device Manager.
- Locate your capture card under “Sound, video and game controllers.”
- If there’s a warning symbol, try reinstalling the drivers.
5. Update or Reinstall Drivers
Outdated or incompatible drivers can cause the ‘No Signal’ error. Update your drivers by following these steps:
- Go to the manufacturer’s website and download the latest drivers for your capture card.
- Uninstall the current drivers from your system.
- Restart your computer and install the updated drivers.
6. Disable HDCP on Consoles
If you are capturing gameplay from a PlayStation or other consoles, ensure that HDCP (High-bandwidth Digital Content Protection) is disabled:
- For PlayStation, go to Settings > System and uncheck “Enable HDCP.”
- Restart your console and capture card after making this change.
7. Check for Software Conflicts
Other programs that use video capture, such as Skype, Zoom, or Nvidia’s ShadowPlay, may interfere with Streamlabs OBS. Close any unnecessary applications running in the background:
- Press Ctrl + Shift + Esc to open Task Manager.
- Look for resource-heavy programs that may interfere with Streamlabs OBS.
- Close any unnecessary apps and restart Streamlabs OBS.
8. Adjust Resolution and Frame Rate
Streamlabs OBS may struggle to receive a signal if the resolution or FPS settings are incompatible with the capture device. Adjust these settings in the capture card properties by trying different resolution and FPS settings.
