If you have an Acer monitor, there’s a good chance that you’ve experienced the following problem in the past. No matter what kind of computer you use, you can’t get your monitor to display any images or video. No matter how many times you press the on-screen buttons to change your settings, nothing happens.

You can see that the monitor has power, but nothing else—your computer isn’t even picking up an image from the HDMI cable or VGA connection! If this describes your situation, then keep reading!

Solution 1: Disconnect the External Devices

The problem is likely a faulty extension connected to your laptop. Try disconnecting all external devices (printers, cell phones, etc.) and then restart your laptop. If you still have problems, try connecting one device at a time until you find which one is causing your issues.

You may also want to check if any of these devices require updated drivers. If so, update them before reconnecting them. Sometimes an older device or an outdated driver can cause video issues.

Solution 2: Check Your Cables

Make sure that your VGA, DVI, or HDMI cable is securely connected. Each connection requires a different type of cable. If you have multiple cables going from your computer to your monitor, make sure that they are all firmly connected.

You may also want to check and see if you have any loose or frayed cables. A bad connection can cause issues just like a loose wire can. 

Try swapping out your existing cable for another one to determine whether it’s an issue with your particular cable or something more serious. If there are several people using monitors in your office, try using another person’s monitor on your computer to test whether it works properly with their system.

It could be that there is something wrong with one of those computers instead of yours. If nothing else works, it might be time for a new video card.

Solution 3: Reconnect Your Computer

It could be that you turned on the monitor but forgot to turn on the computer. The monitor displays no signal until it receives a valid signal from the computer to display a video.

In this case, simply turn on your computer and try again. If your monitor is connected to your laptop via an HDMI cable, make sure that both devices are switched on and properly connected.

If all else fails, check for any loose cables or connections between your laptop and its peripherals (including external monitors).

Solution 4: Install the Latest Graphics Card Driver

Updating your graphics card driver is often an overlooked way of fixing a software-related problem, but it can help you resolve many display issues. This is because it will enable you to use any additional functions provided by your graphics card’s most recent version.

To install a graphics card driver, follow the steps below:

  • Go to your Device Manager.
  • Select your graphics card and click on Update Driver.
  • You should then be prompted with a window where you can choose what type of driver you want: ‘Update Driver‘ or ‘Search automatically for updated driver software‘.
  • Clicking ‘Search automatically for updated driver software‘ will mean that Windows searches for an available new version of your graphics card’s driver without further input from you.

It is also important to check if your graphics card is not damaged or too old. To do so, follow these steps:

  • Open Device Manager.
  • Expand Display adapters.
  • Double-click on the item corresponding to your Graphics Card. This should display detailed information about its hardware.
  • If there is an X beside it, your graphics card has been disabled.
  • If there is a yellow triangle beside it, that means that your graphics card driver may be out of date or damaged.

That’s why we recommend updating both hardware and drivers as a first step towards fixing the ‘Acer monitor no signal’ problem. 

Solution 5: Reset the BIOS

If you have an Acer monitor that is not displaying anything, one way to fix it is by resetting BIOS. This allows you to have a fresh start on your computer system and fix any issues that may have caused your problem. 

To do so, turn off your computer, unplug all wires from the back of it and open up your case. Then remove all but one memory stick or hard drive from each slot before pressing and holding each of your power buttons for about 10 seconds. After doing so, replace your components and try turning on your computer again. 

If you still have a blank screen after trying these steps, then you may need to format the whole system.

Solution 6: Format the System

Outdated systems are often a cause of monitor and laptop troubles. Make sure your system has all of its most recent updates, as well as that it is updated with any other recent software you may have installed.

Remove any unnecessary programs or applications from your computer. While they might not be causing an error now, they could be interfering with necessary operations later on.

Also, make sure that there aren’t any conflicts between your devices. For example, if you have multiple monitors connected to one computer, try disconnecting one before continuing to use another.

Solution 7: Call Customer Support 

If you still see a blank screen after trying these steps, there may be an issue with your Acer LCD. Contact Acer Customer Support for help. They’ll likely be able to walk you through a few simple troubleshooting steps. 

It might be nice to have a second display hooked up so you can at least do something while you troubleshoot your non-functional monitor.
