Monitor Shuts Off But Computer Stays On [Solved!]

1- The monitor is Overheating

Monitor Overheating is a common issue that can occur when the internal temperatures in your computer become too hot.

This can cause the monitor to turn off as it cannot handle the high temperatures while the computer remains on.

Monitor Overheating occurs when there is not enough air circulation and if there is dust buildup, blocked vents, and/or too much strain on the graphics card.

It is important to keep your computer clean by regularly cleaning out dust buildup to prevent monitor overheating. 

You should be sure to give your computer plenty of breathing room; make sure that your computer is not placed in a cramped area with limited air circulation.

2- Loose Connection

A loose cable connection is one potential cause of a monitor shutting off but the computer remaining on. 

This can occur when the power or video cable disconnects from the monitor or computer. 

When this happens, it won’t allow the monitor to receive a signal, leading to a blank screen.

Inspect each cable thoroughly to check for loose cables to ensure it is securely connected to the monitor and computer.

If the cable has become loose, try to reconnect it firmly.

If this does not solve your issue, there may be a deeper problem with the monitor or the computer itself.

3- Faulty Power Switch

When a monitor shuts off but the computer stays on, the problem may be usually due to a faulty power switch.

The power switch is a small button on either the back or side of the monitor that must be held down for several seconds to turn on or off.

If the button isn’t held down long enough, the monitor will turn off, but the computer will stay on.

This can also happen if there is an issue with the power cord or power outlet.

To fix this problem, you should try unplugging and re-plugging the power cable into the monitor and wall outlet.

If that doesn’t work, then it’s likely that the power switch needs to be replaced.

If you’re comfortable with taking apart the monitor, then this is something you can do yourself.

4- Faulty HDMI Cable

When a monitor shuts off but the computer stays on, it is often caused by an issue with the HDMI cable.

In some cases, the issue can be as simple as an old or worn-out cable that can no longer transmit data correctly.

If this is the case, replacing the HDMI cable will typically solve the issue.

It is also possible that the monitor is at fault, so replacing the screen might be necessary.

In either case, checking the cables and ensuring they are still in good condition before pursuing other solutions is important.

If the cables appear old or worn out, replacing them should solve the problem of a monitor shutting off, but the computer stays on.

5- Turn Off The Power-saving Mode

The power-saving mode on a computer is a setting that helps to conserve energy and reduce the amount of power the computer uses.

This feature can be adjusted in the system settings of the operating system or manually through the monitor’s control menus.

When this feature is enabled, it may cause the monitor to turn off after a certain period of inactivity while the computer remains on and running.

If your monitor shuts off but the computer stays on, you may have enabled the power-saving mode on your computer or monitor.

To turn this feature off, simply adjust the settings in your operating system or monitor’s control menus to disable the power-saving mode.

This should help to prevent your monitor from shutting off while the computer remains on and running.

6- Uninstall Conflicting Applications

Uninstalling conflicting applications is a key step when troubleshooting the issue of a monitor shutting off but the computer staying on.

When an application that is running in the background conflicts with your monitor, it can cause the monitor to shut off unexpectedly.

To resolve this issue, you must identify any possible conflicts and uninstall them from your system.

To find applications that may be conflicting, you can use the Windows Event Viewer to check for error messages related to your monitor shutting off.

Once identified, conflicts can be removed using the Add/Remove Programs utility in the Control Panel.

7- Update The Graphic Drivers

Another cause of a monitor shutting off but the computer staying on may be old drives.

Updating the graphic drivers can help resolve the issue of a monitor shutting off but the computer stays on.

The latest graphic driver updates can offer bug fixes, performance improvements, and new features that could help improve your computer’s display capabilities.

If you are unsure of how to update the drivers, here is a step-by-step guide that can help:

  1. Go to your device manufacturer’s website and search for drivers for your specific graphics card model.
  2. Download the latest driver available and save it to your computer.
  3. Open the driver setup files and follow the on-screen instructions to install the updated drivers.
  4. After installation, restart your computer so the new graphic drivers can take effect.

Keeping your graphics card driver up to date will reduce glitches and crashes while trying to run programs or games on your computer.

8- Video Card Issue

If the monitor shuts off but the computer stays on, it could indicate a video card issue.

A video card is responsible for displaying images and graphics to a monitor, laptop screen, or another type of display.

If the video card is not working correctly, the monitor may shut off even though the computer is still running.

To determine if the issue is with the video card, check for any visible signs of damage or malfunctioning, such as bulging capacitors, broken components, and burnt traces on the card.

If there are no visible signs of damage or malfunctioning, try connecting a different monitor to the computer to see if it displays properly.

The video card should be replaced if the display works on the new monitor.

If the display still does not work on the new monitor, it is likely an issue with the faulty GPU.

9- Faulty GPU

If a monitor shuts off but the computer stays on, it could indicate a faulty graphics processing unit (GPU).

The GPU is responsible for handling all of the graphics-related tasks within a computer.

So when there is an issue with it, the monitor may be unable to access this information and thus shut off.

Other indications of a faulty GPU include distorted graphics, artifacts on the screen, and incorrect colors.

To determine if this is the case, users should check for any updates for their GPU device drivers and update them accordingly.

In some cases, it may be necessary to install a new GPU to resolve this issue. If none of these solutions work, then the monitor hardware may be.

10- Faulty Motherboard

When a monitor shuts off but the computer stays on, it often indicates a faulty motherboard.

This issue should be addressed immediately in these cases of a faulty motherboard. 

If it is not, then other components in the computer can suffer damage and start to malfunction as well. 

It is important to troubleshoot the motherboard and replace it if necessary to avoid any further damage or issues with the system.

It is also important to examine all connected cables and peripherals to ensure that they are connected properly and not the source of the issue.
