It can be very frustrating to come home after a long day and sit to play some games and find that your Acer monitor displays “no signal” after you’ve turned on your computer. If you’re trying to figure out why your Acer monitor is saying “no signal,” you’re in the right place. There are a few reasons why this could be happening.

An Acer monitor may display “No Signal” if your computer isn’t properly plugged into the monitor. You will need to select the correct input in your computer’s settings if it is. If the problem persists, there may be another issue with your monitor or connections.

Since most of the fixes for reasons for your Acer monitor saying “no signal” are relatively easy, we’re going to break down what the reasons are and how to fix them while doing some troubleshooting.

What Does “No Signal” Indicate?

First things first: let’s talk about what “no signal” actually means. When your Acer monitor says “no signal,” it’s telling you that it’s not receiving any input from your computer. Several different things can cause this: 

  1. A loose connection between your monitor and your computer
  2. The computer is turned off or in standby mode
  3. The wrong input is selected
  4. A damaged cable
  5. A faulty or old graphics card
  6. The monitor needs to be replaced

Keep reading to learn what to do when your Acer monitor says “no signal” and troubleshoot the causes.

Reasons and Fixes for an Acer Monitor that Says “No Signal”

Okay, so you’re sitting there, minding your own business when suddenly, your Acer monitor pops up with a message that says “No Signal.” Now, you’re probably wondering what the heck is going on. Well, don’t worry; we’re here to help. Here are a few different reasons why your Acer monitor might be saying “No Signal”:

Your Computer is Turned off or in Standby Mode

The most obvious reason that your Acer monitor says “no signal” is that your computer is turned off or in standby mode. This is easy to fix – simply turn on your computer, and the problem should disappear.

If it doesn’t, the next thing you should try is restarting your computer. Sometimes the problem can be as simple as a glitch that can be fixed with a reboot.

Monitor has the Wrong Input Selected

Another possibility is that your monitor is set to the wrong input. You have to go into your monitor’s settings and make sure it’s set to the correct input.

Loose or Damaged Cables

Another possibility is that your cable is loose. This can happen if you accidentally bump your computer or if your cat decides to use your monitor as a scratching post. Ensure that the cable connecting your monitor to your computer is firmly plugged in at both ends.

It’s also possible that your cable is damaged. This is most likely to happen if you’ve had your monitor for a while and the cable is starting to show signs of wear and tear. If you think this might be the case, try replacing your cable.

If the cable is securely plugged in and you’ve already tried replacing it, and the problem persists, it could be a driver issue, or the monitor could be faulty.

A Faulty or Old Graphics Card

If you’re still having trouble, then it’s time to check your graphics card. Ensure that it’s properly seated in your computer and that all the connections are secure.

If you’ve recently installed a new graphics card or changed your old one, that could be the culprit. You can try uninstalling and reinstalling your graphics drivers to see if that clears up the issue.

If you’re still having issues, your drivers may be out of date. You can either update them yourself or reinstall them. Depending on your graphics card manufacturer, there will be different instructions. Open up the application on your computer or go to their website to check and see if you have to make any updates.

In some cases, the graphics settings in your BIOS could be the problem. Check your BIOS settings to see if they’re set to the right input. If you’re not sure how to do that, consult your motherboard’s manual.

Monitor Problems

Finally, there may be something wrong with your monitor itself. This is most likely to be the case if you’ve had your monitor for a while, and it’s starting to act up. In this case, you might need to replace your monitor. It may be just a hardware issue that can’t be fixed.

If you have a TV, such as an Insignia TV, or a spare monitor lying around, try plugging your computer into the TV or spare monitor to see if the problem is actually with your Acer monitor. If it is and you need to get some work done, you can use most TVs as a computer monitor.

Before jumping the gun and buying a new one, check if your Acer monitor is under warranty.

Conclusion

So, these were the most common reasons why your Acer monitor might be saying “No Signal.” If you’ve tried all of the above and still get the “no signal” message, chances are your monitor is faulty, and you’ll need to get a new one or try replacing your graphics card.
