What do you think could be the issue with your ViewSonic monitor displaying “No signal” message?
Is the issue with the CPU or the cable connection?
You might be thinking,
“I don’t know, that’s why I’m reading your article,”
Your ViewSonic monitor is displaying “No signal” message due to faulty cable connection, incompatible display settings, or faulty graphics card drivers.
Anyway, in this article, I will break down everything about why your ViewSonic monitor says “No signal” and often turns off after displaying this message.
Let’s dive into it…
Why does my Viewsonic monitor say no Signal?
I already mentioned this above!
Several reasons exist why your monitor is displaying this. Either the cable connection is faulty, RAM stick is dusty or the graphics card is malfunctioning.
One more thing!
If the monitor displays no signal with orange light, it means the source is working but it can’t receive any signal from the selected input.
But what about when it turns off after displaying the message?
Well, your monitor turns off after displaying ‘No signal’ message due to ‘Power-saving mode’
Many monitors are equipped with power-saving features that automatically turn off the display when no signal is detected for a certain period.
The monitor goes into a low-power state to conserve energy. If the “No signal” message persists for an extended duration, the monitor may eventually turn off completely.
How to Fix Viewsonic Monitor No Signal?
Here are the detailed step by step guidelines;
Step 1: Loose cable connection
Most electricians agree that a loose or damaged video or antenna cable connection between the CPU and monitor is the primary reason for a monitor to show a “no-signal” message.
Check the video cable connections between your computer and monitor.
If the monitor continues to display the same error message after disconnecting and reconnecting the cable, proceed to the next step.
Step 2: Software Glitch
Software bugs or glitches are a common issue for many electronic devices including TVs, monitors, and networking devices.
It can cause a device to stop working suddenly or malfunction in some way.
Your monitor may be experiencing a temporary glitch in its operating system, preventing it from decoding the signal from the CPU.
If that’s the case, a factory reset can solve this problem.
Simply press and hold the power button for 60 seconds.
Step 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.
Step 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.
ViewSonic monitor no signal Reset
Resetting the monitor while it displays this message is also a good idea. This will refresh all the connected HDMI or VGA connections and start them fresh.
This process is also known as ‘HDMI’ refresh.
however, to reset your Viewsonic monitor when it displays “no signal,
Now Power on the monitor and check if the “no signal” problem persists.
Q. 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.
Q: Can this be caused by a problem with my computer or other video sources?
Yes, if your computer or other video source is not functioning properly, it may not be sending a signal to the monitor.
Try restarting the computer or video source to see if this resolves the issue. If not, consult the user manual or contact technical support for further assistance.
Q. My Viewsonic Monitor shows no signal, but the CPU is running properly
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.
