Quick Checks

Cables and Connections

A loose or broken cable can make your monitor screen go black. First, turn off your computer. Unplug the video cable from both the monitor and computer. Look at the cable for damage, like bent or missing pins. Check the ports on both devices for dirt or bent parts. If you see damage, use a new, good-quality cable. Cheap or broken cables, adapters, or docks can cause the screen to go black. If you use a docking station, check that its drivers and firmware are updated. Try a different cable or port if you can. This helps you find out if the problem is with the cable or the monitor.

Tip: Always use cables and adapters that fit your monitor and computer. Do not use cheap or wrong converters.

Power and Input Source

Power problems or wrong input settings often cause a black screen. First, make sure your monitor and computer are plugged in and turned on. Check that the power cable is tight at both ends. Press the menu button on your monitor to open the On-Screen Display (OSD). Find the Input Source setting. Go through the choices, like HDMI or DisplayPort, and pick the one you use. Sometimes, the monitor picks the wrong input and the screen goes black.

• Check that the video cable is plugged in well.
• Pick the right input source in the monitor’s menu.
• Use good power strips or surge protectors to stop power problems.

Test with Another Device

Testing your monitor with another device helps you know if the problem is with the monitor or computer. Connect your monitor to a different computer, laptop, or gaming console. If the monitor works, the problem is likely with your first computer or its cables. If the monitor still shows a black screen, the problem may be with the monitor or its settings. Many people fix black screens by using a new cable or adapter. Sometimes, picking the right input source or resetting the monitor also helps.

Note: Changing cables or devices is a fast way to find the cause of the black screen.

Why Does My Monitor Screen Go Black?

You might ask why your monitor goes black, even after you check the cables and power. This can happen for many reasons. The most common reasons are driver issues, power settings, hardware problems, and handshake errors between your computer and monitor. Any of these can make your screen turn black without warning. Let’s look at each reason and see how it can affect your display.

Driver Issues

Drivers are small programs that help your computer work with its hardware, like the graphics card. If drivers are old or broken, your monitor might go black during games or normal use. Here are some ways driver problems can cause black screens:

• Old or broken graphics drivers often cause black screens and crashes.
• Updating drivers with tools like GeForce Experience or Device Manager can fix many display problems.
• Sometimes, you need to update other drivers too, like the motherboard, BIOS, or network adapter, to keep your computer working well.
• Broken system files can also cause display problems. Running a System File Checker scan can help find and fix these files.
• Even after you update drivers, black screens might still happen. This shows that driver problems can be tricky.

Tip: Always get the newest drivers from the official website of your graphics card maker, like NVIDIA, AMD, or Intel.

Power Settings

Power settings on your computer or monitor can also make the monitor go black. These settings save energy by turning off the screen after some time. Sometimes, they turn off the screen when you do not want them to. Here are some ways power settings can cause problems:

• Monitors have power features that turn off the screen after a set time.
• Windows display settings, especially with more than one monitor, can make the screen flash or go black if set wrong.
• If your monitor goes into low power or off mode, you might see a black screen until you move the mouse or press a key.
• Turning off or changing these settings can stop random blackouts.

Note: Check your computer’s power plan and your monitor’s menu for power-saving options. Change them if your screen keeps turning off.

Hardware Problems

Sometimes, the problem is inside the monitor or computer. Hardware problems can make your monitor go black and might need repair or replacement. Here are some examples:

• Bad capacitors in the monitor or motherboard can cause black screens, random shutdowns, or unstable work. Capacitors store and control power. When they swell or leak, they stop working right and mess up power delivery.
• Backlight failures in monitors, especially in some models, can also make the screen go black even if the monitor’s power light is still on.
• Handshake problems between the graphics card and monitor, especially with DisplayPort, can make the monitor lose signal. This often happens when you turn the monitor off and on while the computer is running or during a cold boot. Sometimes, turning off features like DisplayPort 1.2 in the monitor’s settings can help.

Here is a table that shows how often hardware problems cause black screens in some monitors:

Model Series	Common Hardware Cause	Failure Rate (%)
D-Series	Power board capacitor failure	5.7
E-Series	LED backlight failure	6.3

If your monitor’s power light is on but the screen is black, or if you hear strange sounds, hardware might be the problem. In these cases, you may need to replace parts or get a new monitor.

Software Fixes

Update or Reinstall Drivers

Old or broken drivers can make your monitor go black. You can fix this by updating or reinstalling your graphics drivers. Many people say that removing and adding display drivers again helps the screen work. This is helpful after you change the resolution or refresh rate. Sometimes, you need to do this more than once if the problem comes back.

• Go to your graphics card maker’s website for new drivers.
• Use Device Manager or Driver Easy to find and add updates.
• If your screen goes black after raising the refresh rate, lower it again.
• Remove display adapters in Device Manager, then restart your computer so Windows can add them back.

Tip: Always restart your computer after you update or reinstall drivers. This makes sure the changes work.

Adjust Power Settings

Power settings decide when your monitor turns off. If these settings are too strict, your monitor may turn off too soon. IT experts say you should check and change these settings to stop blackouts.

1. Open Control Panel and go to Power Options.
2. Pick your power plan and click “Change plan settings”.
3. Set “Turn Off Display” to a longer time or “Never”.
4. Right-click your desktop, pick Personalize, and change Lock Screen and Screen Saver settings.
5. Make sure the screen timeout is longer than the screensaver wait time.

Note: Save your changes so your monitor does not turn off too fast.

System Updates and Scans

System updates and scans help your computer work better. Updates fix bugs and help your monitor stay on. Malware or broken files can also make your screen go black.

• Run Windows Update to get the newest patches.
• Use antivirus software to look for malware.
• Open Command Prompt and run sfc /scannow to check for broken system files.
• Remove any bad or strange third-party apps in Safe Mode.

Keeping your system updated and free from malware helps stop black screen problems.
