Monitor Says No Signal And Goes To Sleep [Solved!]

Monitor Says No Signal And Goes To Sleep

If your monitor says no signal and goes to sleep, some reasons may cause this problem. First are faulty HDMI cables, adapter and display ports, old or faulty graphics cards, and bad resolution configuration. It may be an issue with the monitor hardware. Check the monitor input source, and if everything seems to be in order, try resetting the monitor. If you still have a “No Signal” message, it is likely a hardware issue with the monitor itself.

How to fix the monitor that says no signal and goes to sleep?

If your monitor says “no signal” and goes to sleep, the first step is to check if all of your HDMI cables, DisplayPort, and other adapters are properly connected. 

If this step doesn’t solve the issue, ensure that the input source on the monitor is set correctly. 

The next step is to check if the graphics card has been firmly inserted into its slot and ensure all necessary resolution configurations have been made. 

If everything looks okay, but there is still no signal, try updating your graphics card driver or attempt a reset of both your monitor’s hardware and firmware settings. 

If none of these solutions work for you, then it could likely be an issue with the actual monitor hardware itself.

Here is a step-by-step process to fix this issue:

  1. Check HDMI Cables
  2. Check HDMI DisplayPort
  3. Check Monitor Input Source
  4. Check Adapters
  5. Ensure if Graphics Card is Inserted Firmly
  6. Check Resolution Configuration
  7. Update Your Graphics Card
  8. Reset the Monitor

Monitor Says No Signal And Goes To Sleep [Solved!]

1- Check HDMI Cables

When a monitor displays the message “No Signal” and goes to sleep, sometimes it indicates an issue with the HDMI cables. 

HDMI cables are the source of transferring the video from device to monitor. So, faulty HDMI cable can cause this problem.

In this case, checking the cables for any visible damage, such as frayed wires or loose connectors, is important.

Sometimes, switching out both ends of the HDMI cable can be enough to get the display working again. 

In other cases, more serious issues may be at play and require further diagnosis or repair.

If you found any damage on either end of the HDMI cable, you will need to replace the HDMI cable before further testing can occur. 

It may also be possible that an incompatible cable type is being used, resulting in a no-signal error.

2- Check HDMI DisplayPort

Another cause when a monitor says “no signal” and goes into sleep mode, it can be because something is wrong with the monitor display port. 

In this case, checking the HDMI or DisplayPort connection is a good place to start. 

If the monitor is connected to a computer, in this case you should check the source device’s video output settings. 

You can check video output settings to ensure that it is using the correct resolution and refresh rate for the monitor. 

If your monitor is connected to a gaming console, try resetting or adjusting its display settings to see if that fixes the problem.

If these steps do not fix the issue, then it may be necessary to disconnect and reconnect the cables between the source device and the monitor.

3- Check the Monitor Input Source

If you have tried the first two steps and you are still facing a problem with your monitor, it could indicate that the monitor is not properly connected to the input source. 

This could be due to an issue with the monitor, such as being set to the wrong input. It means the monitor is not receiving a signal from the source. 

Additionally, this can mean that your monitor is not compatible with whatever you’re trying to connect it with HDMI ports to a computer with a VGA port. 

Lastly, this could mean the monitor has gone into power-saving mode due to a lack of activity.

4- Ensure if Graphics Card is Inserted Firmly

If the monitor is still saying ‘no signal’, it usually indicates that the monitor is not receiving any input from the connected computer. 

One possible reason this might happen is if the computer’s graphics card is not firmly inserted into its slot. 

To troubleshoot and to fix this issue, it is important to first check that the monitor’s cable is securely connected to the graphics card. 

If the monitor’s cable is connected properly, it may be necessary to open the computer and check that the graphics card is firmly inserted into its slot. 

Once the monitor can receive a signal again, it should go out of sleep mode and resume normal operation. 

If the monitor continues to say ‘no signal,’ it may be a sign of a more serious problem, and other troubleshooting steps should be taken.

5- Update Your Graphics Card

If you ensure that your graphics card is firmly inserted and your monitor still displays the message “no signal” and goes to sleep, it indicates an issue with the graphics card. 

Old or faulty graphics cards can cause the monitor not receiving any video signals from the graphics card to display the image on the screen. 

Replacing the faulty graphics card is often necessary to resolve this issue.

It’s also important to ensure the monitor and graphics card are both compatible with each other. 

If the monitor is not compatible with the graphics card, then it will result in a “no signal” message being displayed on screen. 

Lastly, check all cables are properly connected from the monitor to the PC and graphics card. 

If none of these solutions work, it may be a problem with your monitor’s hardware.

6- Check Resolution Configuration

If the monitor still says no signal and goes to sleep, it indicates something wrong with the resolution configuration. 

Checking the resolution configuration ensures that the monitor is set to use a display resolution that it can recognize. 

This involves adjusting the monitor’s settings to match the maximum supported resolution. 

You should also ensure that all cables and connections used to connect the monitor are secure, as a loose connection can cause lower resolutions or no signal.

If the monitor still says no signal and goes to sleep despite proper resolution setup, you need to look at some other possible solutions. 

7- Reset the Monitor

If the monitor says “no signal” and goes to sleep, a factory reset must be done and it can fix your monitor problem. 

First, turn off the monitor and unplug all cables from the monitor or device it is connected to. 

Next, hold down the monitor’s power button for 30 seconds to discharge any residual electricity. 

Once this is done, plug all the cables back into the monitor and turn it on. If the monitor still says “no signal” and goes to sleep, a factory reset must be done. 

To perform a factory reset, press and hold down both of the monitor’s menu buttons for 10 seconds or until you hear a beep sound. 

The monitor should now display its self-test screen. The monitor may then display the message “reset monitor” or a similar prompt on the screen. 

Select the reset monitor option to complete the factory reset process, and you should now see an image appearing on your monitor.

8- Hardware Issue of Monitor

A few different issues could cause faulty hardware on a monitor. 

One of the most common reasons for monitor failure is an issue with the monitor’s power supply, which can cause it to display a “no signal” error. 

It could also be due to an issue with the monitor’s cables or ports, such as loose connections, damaged cables, or incompatible connections. 

Lastly, the monitor could be going to sleep due to a lack of power from the computer or incorrect power settings on the monitor itself. 

If you are experiencing this issue, it is important to check these potential causes before continuing with more complex troubleshooting measures. 

If there appears to be an issue with faulty hardware, it is best to contact a professional technician to repair or replace the monitor.
