Question:

What could be causing intermittent black screen issues on my monitor or PC?

I have a LG UltraGear GQ850B monitor and a MSI 4080 GPU connected via display port. The monitor sometimes goes black for a split second during start up, normal use, or gaming. I have tried replacing the display port cable, updating the software, and checking the power connections, but the problem persists. My CPU is a 5800X3D and my PSU is a EVGA Supernova GT 1000w. How can I diagnose and fix this issue?

Answer:

If you have ever experienced a sudden black screen on your monitor or PC, you know how frustrating it can be. You might wonder if your device is broken, or if there is something wrong with your software or hardware. Fortunately, there are some possible causes and solutions for this common problem.

One of the most likely causes of a black screen is a faulty or incompatible display driver. A display driver is a software component that communicates with your graphics card and your monitor, and allows them to work together. If the driver is outdated, corrupted, or not compatible with your device, it can cause the monitor to go black or blank.

To fix this, you can try updating the display driver from the Device Manager. To do this, follow these steps:

• Press (Windows key + X) and click on “Device Manager”.
• Expand “Display Adaptor”.
• Right click on the video driver and select “Update Driver Software”.
• Follow the on-screen instructions to complete the update.
• Restart your computer and check if the issue persists.

Alternatively, you can also manually download the latest driver from the manufacturer’s website and install it. Make sure you choose the correct driver for your device model and operating system.

Another possible cause of a black screen is a faulty or loose cable connection. If the cable that connects your monitor and your PC is damaged, worn out, or not plugged in properly, it can cause the signal to drop or interfere, resulting in a black screen. This is especially common with digital signals, such as HDMI or DisplayPort, which require a strong and stable connection.

To fix this, you can try replacing the cable with a new one, or using a different port on your monitor or PC. You can also check the cable for any signs of damage, such as bent pins, frayed wires, or exposed connectors. Make sure the cable is securely plugged in on both ends, and avoid any twists or bends that could affect the signal quality.

A third possible cause of a black screen is a power supply issue. If your PC or monitor does not receive enough power, or if there is a power surge or outage, it can cause the screen to go black or blank. This can happen if your power supply unit (PSU) is faulty, overloaded, or not compatible with your device. It can also happen if your power outlet, surge protector, or extension cord is defective or overloaded.

To fix this, you can try using a different power outlet, surge protector, or extension cord. You can also check the power cable for any signs of damage, such as burns, cuts, or cracks. Make sure the power cable is securely plugged in on both ends, and avoid any overloading or overheating that could affect the power supply.

If none of the above solutions work, you might have a hardware issue with your monitor or PC. This could be due to a faulty or incompatible component, such as the graphics card, the motherboard, the RAM, or the hard drive. To diagnose and fix this, you might need to contact a professional technician or the manufacturer’s support team.

In

conclusion, a black screen on your monitor or PC can be caused by various factors, such as a display driver, a cable connection, or a power supply issue. To fix this, you can try updating the driver, replacing the cable, or using a different power source. If the problem persists, you might need to seek professional help or replace your device.
