HP Monitor Going To Sleep No Input Signal [Fixed]

HP monitor going to sleep no input signal

If your HP monitor is going to sleep with no input signal, there are a few possible causes. Firstly, you should check the cables connecting your monitor to its input sources, such as DVI and HDMI cables or DisplayPort cables. If these are faulty or loose, this will cause the monitor to go into sleep mode. You may also have a faulty monitor, so it’s important to check this too. Another potential cause is the input source, if you are using an adapter such as DVI-VGA or HDMI-VGA, make sure that these are working properly.

How to fix an HP monitor going to sleep with no input signal?

One of the most common reasons why an HP monitor may go to sleep with no input signal is a faulty connection. 

To troubleshoot, ensure that your DVI and HDMI cables, DisplayPort cables, and adapters connected to the screen are all working fine. 

You also have to make sure that you are using the correct input source for the monitor if these check out then there could be a fault with your hardware. 

If everything checks out then it might be due to faulty hardware on which you need to ensure resolution and configuration settings are correct and if needed update graphics card drivers. 

Additionally, try cleaning out any dirt or dust from the RAM slots. Because dust can cause overheating which can lead to issues with the monitor.

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

  1. Check DVI, HDMI Cables
  2. Check DisplayPort Cables
  3. Faulty Monitor Input Source
  4. Faulty Adapters
  5. Check Resolution Configuration
  6. Update Your Graphics Card
  7. Clean The RAM

HP Monitor Going To Sleep No Input Signal [Fixed!]

1- Check DVI, HDMI Cables

It is important to check the cables connecting the monitor to the computer when HP Monitors go to sleep and show the message “no input signal”. 

It must be ensured that both the DVI and HDMI are properly connected at both ends. The connections have to be fine if you wish for monitors to detect video signals. 

Also, it is of extreme importance to look for power lights on the monitors, making sure they are illuminated at all times. 

If any cord plugged into a wall outlet is of bad quality or faulty, you may need re-seat it. 

It’s also important for one to consider any settings that could cause HP Monitors designed for going off with “No Input Signal.” 

2- Check DisplayPort Cables

An important step while checking the DisplayPort cables for HP monitors that are going to sleep and no input signal is ensuring that both ends of the cable are securely connected and in good condition. 

It should be ensured that there are no signs of physical damage, such as exposed wires or fraying of the cable material before connecting it to an external display adapter. 

If a damaged cable is found, replace it immediately. Next, ensure that your HP monitor’s DisplayPort connection is seated properly in its port, and gently wiggle the connector if necessary. 

Reset your HP monitor by unplugging the power cord and holding down the power button for 30 seconds then reconnecting it back into the wall outlet. 

Lastly, connect an external display adapter correctly to both your HP monitor and computer’s video card before using them again.

3- Faulty Monitor Input Source

There is an issue with the monitor Input Source in HP monitors which is usually caused when the monitor loses its connection to the signal source because of incorrect connection or damage in the cable.

In this case, your monitor goes into sleep mode and shows “No input signal” on screen. 

It’s also possible that a faulty cable may be causing this problem, so it’s important to check your cables for any visible damage or loose connections before trying to connect your HP monitor again if they all look fine. 

If you are still having trouble connecting your HP monitor despite everything looking normal with your cables, there could be a setting problem.

4- Faulty Adapters

If your adapter is faulty, it can cause your HP monitor to go into sleep mode. 

This happens when the power from the adapter does not reach the monitor or if its connection with the adapter is faulty. 

In addition to this reason, incorrect configuration of video cable, incompatible graphics card, driver issues, and malfunctioning motherboard may also make your monitor enter sleep mode. 

To troubleshoot this problem properly you will have to ensure that both the adapters are connected correctly and providing enough power supply. 

Once that’s done get eliminated all other possible problems like wrong configuration in video cable and incompatibility with graphic cards along with drivers issues and malfunctions in motherboard.

5- Check Resolution Configuration

If your HP monitor is going to sleep and is saying “no input signal”, it could be caused by a resolution configuration issue. 

Ensure that the resolution settings on your HP monitor completely match the display settings for your computer. 

The ideal performance of your devices will be ensured when the display output matches the native resolution of your HP monitor. 

If you are using a laptop, make sure that it is connected with an appropriate cable to the HP monitor’s display port/input socket. 

Check if the user guide or manufacturer specifications of your device give information about its native resolution and adjust accordingly. 

It may also be necessary to update graphics card driver in order to use certain resolutions and refresh rates on some models of Hp monitors.

6- Update Your Graphics Card

Updating your graphics card is one of the most important steps to take if your HP monitor is going to sleep due to a lack of an input signal. 

If the issue persists after checking all other potential causes, updating the graphics card can often be a fix. 

It’s important to make sure that you are using the most recent driver for your graphics card. 

This can be done by downloading the appropriate driver from the device manufacturer’s website, or through your computer’s control panel. 

If you’re unsure which type of graphics card you have, contact Customer Support for assistance in determining and obtaining the correct driver version. 

Once the updated driver is installed, restart your HP monitor and see if the issue has been resolved.

7- Clean The RAM

An HP monitor showing a “no input signal” error usually means there is something wrong with the RAM of the computer. 

A computer’s RAM holds all its active data for instant access and when it gets overloaded or fails, it may cause the monitor to show a “no input signal” issue. 

Scanning and fixing corrupted/overloaded RAM often solves this problem completely. 

Also, an outdated or faulty graphics card driver, bad cable connection, or hardware malfunction in the monitor itself could be other reasons responsible for this issue. 

To find out what actually fixes it, troubleshooting should be done before anything else to determine the underlying problem.

8- Reset the CMOS

For troubleshooting frequent issues with HP monitors going to sleep due to no input signal, resetting the CMOS is a very common method. 

It is advisable that you first try this step before attempting any other option. 

As we know, CMOS stores all the necessary settings for the computer’s smooth functioning such as system date and time and BIOS setup information. 

Resetting it can help deal with various problems like your computer not recognizing hard drives or even not powering on at all. 

First, carefully remove or short out the battery from your motherboard then wait for a few minutes before powering up your monitor again. 

Hopefully, it will solve the issue of no input signal coming in to work properly.

9- Replace Your Hardware

You can replace your older hardware, such as your HP monitor, to resolve sleep issues and get your computer working smoothly. 

If the computer is sending a signal but the monitor is not responding correctly, try replacing it with a new or tested one. 

Before buying a new monitor, make sure that it has the correct ports to connect it with your machine and check its settings for proper functioning. 

If this does not help, you may need to switch over to a different monitor and if the new one displays an image then know that your previous was incompatible or faulty. 

Lastly, if you are facing trouble in sending signals from the computer to the monitor because of graphics card issues then you should consider updating or replacing it.
