Gaming PC Won’t Connect To A TV

ByMarlo Strydom Updated on

When trying to connect your gaming PC to a TV and encountering issues such as a “no signal” message or a black screen, several troubleshooting steps can help you resolve the problem and enjoy your gaming session.

1. Ensure All Cables Are Inserted Properly

Check all cable connections between your gaming PC and the TV. Depending on your setup, you might use a VGA, DVI, or HDMI cable. Ensure the cable is firmly inserted into both the TV and the PC. If the TV still doesn’t display anything, proceed to the next steps.

2. Choose the Right Source on the TV

Make sure the correct input source is selected on the TV. Use the TV remote to select the input source that matches the port where your cable is connected (e.g., HDMI 1, HDMI 2). If unsure, refer to the TV’s user manual.

3. Reseat the Graphics Card

Sometimes, the graphics card (dGPU) might become loose, especially if the PC was moved or shipped. Here’s how to reseat it:

  1. Open the side panel of your PC case.
  2. Disconnect the power cable from the graphics card.
  3. Remove the graphics card from the PCIe slot by unlocking any clips holding it.
  4. Reinsert the graphics card firmly into the PCIe slot and reconnect the power cable.
  5. Close the PC case and check the connection again.

4. Plug the Cable Into the Right Port on the Gaming PC

Ensure the cable is connected to the correct port. If your CPU doesn’t have an integrated GPU (iGPU), you need to connect the HDMI/Display cable directly to the graphics card’s port, not the motherboard’s ports.

5. Check if the Gaming PC Detects the TV

On your gaming PC:

  1. Right-click on the desktop and select “Display Settings.”
  2. Scroll down to “Multiple Displays” and click “Detect.”
  3. If detected, arrange the displays accordingly and check the resolution and refresh rate settings.

6. Perform a Clean Install for the Latest Display Drivers

Corrupt or outdated drivers can cause connection issues. Use Display Driver Uninstaller (DDU) to remove old drivers in safe mode and then install the latest drivers from the GPU manufacturer’s website:

7. Install the Display Drivers in Compatibility Mode

Run the display driver installer in compatibility mode if you face issues after a major OS update:

  1. Right-click the driver installer and select “Properties.”
  2. Go to the “Compatibility” tab.
  3. Check “Run this program in compatibility mode for” and select the previous Windows version.
  4. Run the installer and restart the PC.

8. Run the Troubleshooter for Hardware and Devices

Windows provides a troubleshooter for hardware issues:

  1. Open Command Prompt as Administrator.
  2. Run the command msdt.exe -id DeviceDiagnostic.
  3. Follow the instructions to troubleshoot hardware and device issues.

9. Power Cycle Your TV and Gaming PC

Performing a power cycle can reset connections:

  • PC: Shut down, disconnect the power cable, hold the power button for 60 seconds, reconnect, and start.
  • TV: Turn off, unplug, wait 60 seconds, plug back in, and turn on.

If none of these steps work, test your gaming PC with a monitor to rule out PC issues and test the TV with another device to check for TV problems. If problems persist, professional assistance may be necessary.
