Common causes of the “No Signal Detected” issue
Incorrect Input Source: The monitor may be showing from the wrong input source. Ensure that the correct selection of input source (HDMI, DisplayPort, DVI, VGA, etc.) is made. You can swap between different input sources using the menu buttons on the monitor.
Faulty or Damaged Cables: Ensure that the video cable runs out of the monitor and into the computer is tightly and securely connected. Loose or damaged cables can hinder a signal from being passed to the monitor. Make a visual check on the cable for damage or bent pins.
Power Problems in the Power Supply: Check that the monitor is powered and the power line is correctly dropped onto the monitor and plugged into the power socket. The outlet can also be tested with another device.
Graphics Card Compatibility Issues: It could always be that of the monitor towards a graphics card. Make sure that graphics drivers are updated. If you had recent updates and the problem started at that point, consider going back to a previous version.
Monitor Settings: The monitor sometimes has settings that may need reset. You may reset factory settings with the monitor on-screen display (OSD) MENU.
Test with Another Computer: As a test procedure, you may connect the monitor only to another computer to test whether the problem could originate from the monitor or the computer. Suppose the monitor display is fine on another computer. In that case, it tells you that the former computer has a graphics card or setting issue.
Power Cycling the Monitor: As a last resort, the monitor can reset itself if it encounters an error. Please turn off the monitor and unplug it from the power source. Please wait 10 to 15 minutes, then plug it back in and turn it on.
Troubleshooting steps for the “No Signal Detected” issue
Now that we have identified the possible causes let us move on to the steps for troubleshooting to help you fix the “No Signal Detected” issue on your ViewSonic monitor.
Checking the connections
First, ensure all the connections between your monitor and the computer are secure. Now, turn the devices off and inspect the cables for damage. Now, gently unplug each cable one by one and replug it firmly into its port; make sure they are correctly seated in their sockets. Also, make sure that if you use an adapter or converter, you connect it correctly. Now, turn on the power of your devices and test whether the problem is solved.
Updating graphics drivers
Outdated graphics drivers can often be the culprit behind the “No Signal Detected” problem. To update your drivers, follow these steps:
- Press the Windows + X keys and click “Device Manager.”
- Just click on “Display adapters.”
- Right-click on the graphics card and press “Update driver.”
- Choose the first position; click on the automatic search.
- Windows will look for the latest driver and install it on your computer.
- Once it’s complete, restart the PC and check if the problem persists.
Adjusting display settings
If the “No Signal Detected” issue persists, it might be due to incorrect display settings. Follow these steps to adjust your display settings:
- Right-click on your desktop and click on “Display settings.”

- Click on “Display adapter properties.”
- Under the “Monitor” tab, you could click the drop-down, select a lower resolution rate, and refresh.

Testing the monitor on a different device
Isolate the computer as a problem source by testing your ViewSonic monitor on another device. Connect the monitor to a laptop or any other computer using another cable. If the monitor works fine on the other device, it indicates a problem with your computer. However, if the “No Signal Detected” problem persists on the other device, the problem lies with the monitor.
