Fix Acer Monitor No Signal Issue?

Fix Acer Monitor No Signal

It’s not difficult to connect a monitor to a computer system. You only need to connect the power supply after you plug the monitor into the motherboard.

Your monitor might not get any signal from the system if the proper cable is not used or the monitor input settings are off. Removing and reconnecting all the monitor cords on your Acer monitor should resolve the No-signal problem. You might also need to execute certain OS adjustments if a faulty driver or system file brings on the issue.

In this post, you will learn about the potential causes of No-Signal errors in Acer monitors. The fixing methods are also included in the discussion.

Why is My Acer Monitor Displaying No Signal?

You see the No Signal error message on the monitor when there is no signal entering the monitor’s input port. It could be due to a damaged cable or wrong input settings.

Here is the list of the most likely causes of No signal on your Acer display:

  • Wrong monitor input settings
  • Damaged display cable
  • Mismatched cable version
  • PC is unable to detect the graphics card
  • Physical damage to the monitor
  • iGPU disabled from BIOS

How to Fix Acer Monitor That Displays No Signal?

First, you need to check whether your monitor is creating a problem or your computer system is. To do so, check the monitor on a different computer. If it functions, the system is probably the problem. You can check on your computer using a different monitor as well.

If the display operates without any problems, the monitor is the problem. Getting into the BIOS is another technique to troubleshoot the monitor display error. You can also try the following instructions to resolve the No Signal error.

Unplug and Plug the Power Cable of your Monitor

The users claim this is the simplest solution to the Acer monitor’s no-signaling issue. The monitor’s power cable must first be unplugged and then re-plugged a short time later. Following this, you must ensure that the problem has been resolved. If not, try the next fixing solution.

Check the Input Source

The improper input source could be to blame for an Acer display with no signal. For connecting multiple devices to one display, such as a PC and a game console, most monitors have numerous input options, including DP, VGA, HDMI, and DVI. To switch between them, you can utilize the firmware menu on display. You should confirm that the input source is accurate in order to resolve the no-signal issue.

Here are the instructions to choose the correct input source on your Acer monitor:

  • Activate the monitor and computer.
  • To access the menu, click the display’s edge button.
  • Open the “Input Source” option and select the appropriate option. For example, if you connect your monitor to your computer’s HDMI port, you should choose HDMI as the input source.

Check the Cable

It is a quick remedy for an Acer display that isn’t receiving a signal. The No-Signal error will appear if your monitor and computer have a loose connection. Thus, make sure your cable is securely connected.

Also, see whether the cable is broken. If it is, swap it for a new one and then check the monitor’s functionality.

Check if the PC is in the Sleep Mode

Your computer cannot receive any signals while it is in sleep mode. Press any key on the keyboard to wake up your computer system. You can also move the mouse to do so.

Check if Your Graphics Card Is Firmly Inserted into the Slot

The Acer monitor may not display any signal if your graphics card is not firmly fitted into its slot. Therefore, have a look at it by opening your computer case. Here is the detailed procedure:

  • Turn off your Acer computer and disconnect all of the wires.
  • Locate the graphics card on the motherboard by opening the computer casing.
  • Now remove the graphics card from its slot and securely re-insert it.
  • Reattach the power wire to the monitor and link it to the computer.
  • Press and hold the power button for a minimum of 30 seconds. After that, connect the power cable and then switch on the computer.

Update the Graphics Card Driver

An unreliable graphics driver may cause an Acer display to lose signal. It would help if you upgraded the driver to resolve this problem.

Visit the manufacturer’s website and download the appropriate driver based on your computer’s specifications (PC model, video card model, and system version). Once you have finished downloading, install the driver on your computer system.

Check Power Supply to the Motherboard and the GPU

There is a possibility that the motherboard is not giving the graphics card adequate power. You can examine the cooling fan of the GPU to verify this. There is a possibility that the GPU is not receiving enough power if the fans are not running.

But the point to focus on is spinning fans does not imply that the GPU gets enough power. The GPU cooling fan may run on a low-power PSU. But the GPU won’t operate well in this case. As a result, the monitor may show a “No signal” error.

You need to make sure that the PSU provides enough power for the complete system in order to resolve this problem. You can use the official Coolermaster PSU calculator if you are unsure whether the PSU is providing adequate power.

Check Memory Modules

You need physical RAM for your system as it displays data on the screen. Your monitor will not show anything if your system has a memory issue. So make sure your memory modules are working perfectly.

Also, if RAM sticks are not correctly placed into the motherboard, the computer won’t recognize the RAM and will display a No signal error.

To test the memory module, follow the directions listed below:

  • Disconnect the power supply from the wall outlet.
  • Remove all the screws holding the side panel to the Computer case to reach the motherboard. Here you can see long memory slots close to the CPU socket. 
  • There will be locks on either side of the memory slot. Carefully remove one RAM stick by pulling the lock outward.
  • Start the computer and see whether the monitor shows anything. If not, take out another Memory stick and restart the computer.

Suppose your system only uses one memory stick. In this case, you will need another one to determine whether the current RAM stick is defective.

Factory Reset Monitor

A factory reset monitor can restore all configurations to their original condition. A factory reset should resolve the problem if you have mistakenly changed the Monitor’s settings.

Here is the method to do a factory reset:

  • Locate the buttons under the monitor’s screen or on the sides.
  • Open the “Settings” menu and then select “Reset” to restore the Acer monitor’s original settings
  • In the end, press the “Yes” button.


No-signal error is a common issue. You may experience it on any computer system. But it’s not the thing to worry about. You can quickly fix it.

In order to resolve the issue, you need to identify the root cause of the problem. Check the input source, cables as well as graphics card connections. It will help you detect the component causing the no-signal error. Then you can use the methods mentioned above to fix it.
