Why Does My Monitor Keep Going Black? (Answered)

One of the most frustrating things could be when you are working and you suddenly see your monitor turning off or going black. Generally, this does not hamper anything you have been doing, aside from gaming. However, you will need to turn the monitor back on and this might be frustrating if it happens repeatedly.

The most common reason for a monitor going black is a damaged power connection.

Having damage to your cables can often reduce the power sent to the display. Since the display uses plenty of power to start up and give you a visual, it might be the first thing to turn off in a situation where power is insufficient. 

While replacing or fixing your power supply is one way to go, various other reasons could be causing the dreaded and feared black screen. Some also refer to it as the screen of death. We aim to help you understand which problems might be responsible for this happening to your monitor.

Most Common Reasons Your Monitor Keeps Going Black

Knowing what could be causing the problems might alleviate some fear. Most of these common reasons for your monitor going black have some easy solutions. You will find that with a few tweaks and even adjustments of cables, you could have your monitor back in the ideal operating condition for work:

1. Cables Are Damaged

When it comes to your PC, you often have a VGA or HDMI cable that runs from the output on the PC to the input in your monitor. The cable is responsible for transferring the display from one device to the other. If there are any faults, it could hinder this from happening and you might not have clear visuals.

2. Power Supply

The power supply is another one of the main cables that run from the monitor to the plug. It will keep the monitor on and functioning. In terms of power usage, your display and screen will use the most power to stay active. However, when you have a broken or damaged power supply, it might not supply enough power to keep the display running.

3. Corrupt Or Outdated Drivers

If you know anything about tech and computers, you will understand that drivers are some of the most important software components. They are responsible for operating virtually everything on your PC. Outdated or bad drivers could be causing a communication glitch in the HDMI or display cable. The simplest solution would be to troubleshoot them and ensure they are up to date.


These are the three main causes for a monitor going black. However, physical damage to the screen or the internal wiring might also result in the same thing happening. You should consider these three causes before you take your monitor to a specialist for repair. Let us know in the comment section which reasons were responsible for your monitor going dark.
