Why Does My ViewSonic Monitor Show No Signal?

When the monitor is turned on and does not receive signals from the other device, like a laptop or CPU, it usually shows no signal message on display.

How to Fix ViewSonic Monitor No Signal Issue?

The No Signal issue on monitors usually indicates that your monitor is not receiving signals on the selected input option like HDMI, VGA or DVI.

Without wasting our time, let’s discuss all the fixes below.

Check Monitor Input

First, check the monitor input and set your monitor on the correct input or source mode. If you are using the HDMI cable, ensure your ViewSonic monitor’s HDMI input option is active on the monitor.

Let’s also explain the steps how to change Viewsonic monitor Input:

  • Press the “Source” or “Input” button.
  •  Scroll down to Input Menu through the arrow keys.
  •  Select the Input option and choose your connectivity option (HDMI, DVI, VGA or C-Port).

Un-Plug & Re-Plug Your Connectivity Cables

If your monitor is set on the correct input option, unplug your connectivity cables for your monitor and other devices. Just clean both ends of your connectivity and re-plug them in your monitor and another device.

Check Your Connectivity Cables

Unplug your connectivity cable from the monitor and another device, check the cable in detail and try to get a damaged spot in the cable.

If you got any damaged spots in the cable, you must replace your connectivity cable here.

If you don’t get any damaged spots in the cable, you must move to the other fixes to fix your monitor issue.

Check Connectivity Cable on Other Devices

If your connectivity cable is physically fine and you are still facing the issue, here, in this case, you need to check your existing cable on the other device in your home, or you can also check it on your friend’s or neighbour’s device.

Check Your Devices Slots or Ports

After this step, you need to ensure that your device’s connectivity input ports or slots are in a workable position. Here you will need to check both slots. You can move to the next step if they are intact and rust-free.

If they are broken or rusty, then you will need to fix them, and then you will check your ViewSonic connectivity with the other device.

Try Different Connectivity Options

If all the above steps and fixes don’t solve your issue, you must try a different connectivity option.

If you use an HDMI cable to connect with the other device, we recommend trying a different cable (DVI, VGA or C-Port).

After changing the cable, remember that you must change the monitor Source or Input option.

Outdated Drivers

Outdated or incorrect drivers can cause compatibility issues with your monitor. Update your video card drivers to ensure they are compatible with your ViewSonic monitor.

Resolution and refresh rate

Adjust your computer’s resolution and refresh rate to match the settings your monitor recommends. This can be done in the Display Settings of your computer’s Control Panel.

Reset the monitor settings.

Resetting the monitor settings can also help resolve the issue. Press the menu button on the monitor and navigate to the factory reset option to reset the settings.
