1. Loose cable connection

A loose video cable connection is one of the most common reasons that can trigger this issue. Most electricians say that the primary reason for a monitor or TV to show a no-signal message is the loose or damaged video or antenna cable connection that sends the signal from the CPU to the monitor.

So, when you see this message on your computer monitor, you should first check the video cable connections between your computer and monitor. But if your monitor is still displaying the same error after disconnecting and reconnecting the cable, proceed to the next step.

2. Software Glitch

A Software Bug, also known as a “Software glitch,” is a common issue for almost all electronics, including TVs, monitors, and other networking devices. Generally, a software glitch causes a device to start misbehaving, like stopping working some function suddenly or not working completely.

So your monitor may be facing a temporary glitch in its operating system, preventing it from decoding the signal that the CPU is sending. In this case, a factory reset can solve your problem.

You can reset your Viewsonic monitor by pressing and holding the power button for about 60 seconds. It will fix any software-related error, recover your monitor to its default mode, and fix your issue.




3. Problem with the source device

Let me ask you one thing: did you even turn on your CPU? Or you just turned on your monitor instead of powering on the CPU first?

We occasionally forget to turn on the computer after turning on the monitor. Until it detects a reliable video signal from the computer or source, the monitor will show a “No Signal” warning. So, please make sure your computer is turned on.

If your computer is turned on and you have checked the cable and cable connections, but you are still getting a No Signal message from your Viewsonic monitor, check this by:

  • Connecting another display with your computer.
  • Connecting the same display with another computer.

4. PC’s Hardware Issue

If none of the above steps doesn’t work and your Viewsonic monitor is still displaying the No-Signal message, there is a probability that one of your PC’s internal components, like the graphics card, is faulty or the RAM stick is dusty. In this case, checking and cleaning can both fix this issue.

Before you disassemble your PC, make sure your computer is turned off. Also, unplug all cables, including the power cord, which will help you to avoid electric shock.

After then, open the PC’s back case and locate the graphics card first, as this is the most likely to cause a no-signal issue if it is loose or damaged. Then check the RAM sticks. If the RAM stick is dirty or dusty, clean it.





FAQ

1. Nothing worked! What to do?

Unfortunately, suppose none of those mentioned above methods work and your monitor is continuously displaying the same warning “no-signal”. In that case, your monitor may be damaged, or your PC’s internal component may be broken.

In this case, visit your nearest electronics repair shop or call an experienced repairer and ask him to look into it. You can also contact Viewsonic customer care and discuss your situation with them about your issue. But to get free service, your monitor must have a valid warranty.

2. My Monitor shows no signal, but the CPU is running.

If your monitor is showing no signal, but your CPU is running, likely, your monitor is not receiving a signal from your CPU. The problem could be with the monitor or with the cable connecting the monitor to the CPU.

First, try connecting to another monitor to see if that works. If it does, the problem is with the primary monitor. In this case, you have to buy a new one or repair it. But If the second monitor does not work, then the GPU is not working correctly, or your monitor isn’t receiving any signal from your PC.
