Monitor issues can result from a number of reason including hardware flaws, graphics or video adaptor problem and many others. The worst part is that they are the hardest to troubleshoot and resolve as most of the time you cannot receive an error message to give you a hint about the problem. If you are experiencing monitor issues, no need to panic. This guide will teach you how to troubleshoot and fix common monitor problems in Windows 10.

1. Checking Monitor Connection Issues

If you cannot receive any signals on your screen), it could be a connection issue between your computer and the monitor. The first thing is to check and rectify any connection errors.

• Check to ensure that the connecting signal cables are correctly connected on both ends, using the right cable and ports.
• Moreover, check the light signals to makes sure that the monitor is connected to a power supply and turned on. If the light is off, check the power connection and press the power button to switch on.

• For some monitors, unplugging the power cable and reconnecting after a few seconds of wait can resolve the blank screen issues. This resets the electronic components on the monitor.
• You may also try disconnecting all external devices connected to the PC leaving only the mouse, keyboard and the monitor and then cold boot the PC.
• If you can see light on the monitor, then it means that the problem could be the computer and not the monitor.

2. Troubleshooting Computer Problems

To determine whether the blank screen is due to a computer issue, press the power button on the computer to turn it on and make the following observations:

• Check if you can see the power light on the PC and listen for the noise from the fan. If the power lights are off and no sound is coming from the fans, your computer is not starting and this is the cause of the blank screen.
• If you hear a beeping sound when the computer is starting, some internal components such as the video card, memory module, processor or cables are loosely connected. To fix the problem, you need to open the computer and ensure that all the internal components and cables are firmly in their place.
• If you can see the power lights and hear some noise from the fan, yet nothing displaying on the monitor, then the issue could be due to video cable connections or the monitor.

3. Testing the Monitor and Video Cable/ Connectors

• Disconnect and inspect both the video cable and connect to identify any defects.
• Check for bent or broken pins in the connector and carefully straighten them.
• Reconnect the monitor and turn on the computer and the monitor to see whether the solution has resolved the problem.

• You can use a spare cable to rule out the cable problem. If the monitor works, replace your video cable.
• If you the screen is still blank, try to test the monitor with a different computer. You can also try to connect a different monitor to your PC.

Did it work on a different computer? If no, try servicing or replacing your monitor or proceed to the next step.

4. Resolving Windows 10 Display Detection Issues

In some cases, Windows 10 may have lost its connection to the monitor thus displaying a black screen.

• You can fix this issue by pressing the “Win + Ctrl + Shift + B” keys on your keyboard. This restarts the video drivers and refreshes the display connections.

Fix Display Detection Issues by Switching the Display Mode

Sometimes changing the “Project” mode can fix the blank display problem.

• If you do not see any display on the screen, press the “Win + P” keys on the keyboard to open the “Project” menu.
• Again, press the “P” key and hit Enter to switch the display mode. You can repeat the process 4 times to try all the possible display modes.

5. Reset/ Update the BIOS

Changing some BIOS information like the monitor device settings may develop monitor issues and you can only resolve this by resetting the BIOS to its default configurations.

• Start the computer and repeatedly press F10 or F8, depending on the make and model of your computer, to enter the BIOS settings.
• Press the Down Arrow key three times and then the Enter key two times. This will reset the BIOS settings and restart your PC.

6. Configuring the Display Resolution to Fix Monitor Problems

Another cause of monitor issues in Windows 10 is the incompatibility of computer display resolutions with the monitor device. If this is the case, changing your Windows 10 display resolution and colour depth settings to from the standard to a compatible mode will resolve the monitor issue.

• First, you will need to connect your PC to compatible monitor and power on the machine.
• Right-click the Start button, go to “Shut down or sign out” and then click “Restart” while pressing the “Shift” key on the keyboard.

• Select the “Advanced Settings” and then “Troubleshoot” option. On the resulting screen, click “Advanced options”.

• Choose the “Restart Settings” and then click the “Restart” button on the resulting window.
• After the computer restarts, press “3” or “F3” on the keyboard to enable the “Low-resolution video” setting.

• Wait for the computer to complete the booting process and then reconnect the incompatible monitor. Now you can change the resolution configurations to match the default settings for your monitor.

Summary

Monitor issues in Windows 10 can be due to several reasons and you need to identify the root cause to resolve the problem effectively. If your monitor is not working with your Windows 10 PC, you can try the above troubleshooting options to fix the device.
