How to Tell if Your Monitor Is Dying?

By | August 27, 2023

Your computer monitor is one of the most important parts of your setup. It allows you to view everything happening on your PC.

So when your monitor starts acting up, it can cause major disruptions to your work or entertainment.

Fortunately, there are usually signs that a monitor is failing before it stops working entirely.

Recognizing these signs can help you troubleshoot issues or know when to replace your display.

In this article, we’ll cover common symptoms of a dying monitor and how to respond.

How to Tell if Your Monitor Is Dying?

Warning Signs Your Monitor is Failing

Here are some of the most common indications that your monitor is reaching the end of its lifespan:

1. Image Distortions

One of the first signs of monitor trouble is distorted images. This could include:

  • Wavy or flickering picture
  • Pixelation or blocky images
  • Bars across the screen
  • Double images
  • Colors looking off

Any interference, static, or visual artifacts like this means something is wrong with your display.

It’s usually a problem with the monitor’s internal electronics.

2. Screen Freezing

Does your monitor frequently freeze so that the image is stuck in place? Or does it ever go completely black for a few seconds?

This freezing and blacking out is another red flag.

A monitor may freeze if its capacitors have loose connections or failures. As monitors age, their internal components degrade over time.

3. Strange Noises

Listen closely to your display. Does it make unusual noises like cracking, buzzing, or popping?

You shouldn’t hear anything coming directly from a monitor.

Odd sounds are often due to arcing electricity or short circuits inside. This indicates a hardware problem.

4. Dimming Image

Over time, a monitor’s backlight dims and produces less brightness.

You may find yourself cranking up the brightness setting more and more to compensate.

But if adjusting brightness doesn’t help, the CCFL or LED backlights are wearing out.

Older monitors with CCFL (cathode fluorescent) tubes are especially prone to this.

5. Burn-In

Do you see ghost images or burned-in shadows on your screen even when you change what’s displayed?

Burn-in is a phenomenon in which a monitor’s pixels are permanently discolored from constantly displaying the same content.

While modern monitors are less susceptible, it’s still a problem if you see burned-in images. This happens gradually but is a sign of overall display deterioration.

6. No Signal

The most obvious warning is that a monitor is dying if nothing displays. When you turn it on, there’s no picture – just a blank or black screen.

If pressing buttons doesn’t help, it could mean internal electronic failure.

But first, ensure the monitor gets input signal from the computer and that video cables are secure.

Troubleshooting Steps

If you notice any of the symptoms above, try these troubleshooting tactics before replacing your monitor:

  • Check for loose video cable connections at both the monitor and computer. Re-seat cables firmly.
  • Try connecting your monitor to another computer. If the issue persists, it points to monitor failure instead of a PC problem.
  • Swap out video cables if possible, preferably with a new high-quality cable. Faulty cables can cause distortion or signal loss.
  • Update computer and graphics drivers. Outdated drivers can sometimes cause display issues.
  • Try using different power outlets in case of inconsistent electricity supply. Use a surge protector.
  • Open the monitor case carefully and examine all internal connections. Re-seat any loose ribbon cables or wires. This requires some technical skill.
  • Use canned air to blow out any dust buildup around internal components. Overheating can lead to failure.
  • If you can access a multimeter, check for unusual resistance values or voltages from power supply boards. Any readings outside of spec indicate a hardware defect.

If nothing fixes your monitor, it likely means irreparable electronic failure.

Component-level repairs are difficult for monitors. At that point, you’ll want to buy a new monitor.

When to Replace Your Monitor

When do you know it’s time to stop troubleshooting and buy a new display?

Here are signs it’s not worth continuing to use a failing monitor:

  • Image quality is unacceptable despite adjustments.
  • The screen flickers constantly.
  • You regularly deal with blackouts, freezing, or graphic distortions.
  • Burn-in has caused permanent damage or markings on the screen.
  • The monitor makes abnormal noises, indicating hardware issues.
  • Cracked screen or structural damage.
  • Repair costs exceed the price of buying a new monitor.

For expensive high-end displays, repair may make sense.

But replacement is often better for standard monitors if you consistently see the symptoms above.

Tips for Extending Your Monitor’s Lifespan

You can get the most longevity out of your monitor with proper care. Here are some monitor maintenance tips:

  • Don’t leave your monitor on 24/7. Turn it off when not in use to give it breaks.
  • Use a screen saver or turn off your display when stepping away from your computer.
  • Don’t block vents that allow airflow and prevent overheating.
  • Keep the monitor screen free from dust using microfiber cloths. Avoid harsh cleaners.
  • Make sure your desktop and surrounding area are free of moisture.
  • Don’t stack heavy objects on top of your monitor.
  • Ensure your monitor isn’t subject to vibrations from external sources.
  • Handle your monitor gently when moving and transporting it.

Following the manufacturer’s instructions for care and maintenance will also help your display last.

With a quality monitor and proper handling, you should be able to get at least 3-5 years of regular use before seeing age-related issues emerge.

FAQ About Failing Monitors

Here are answers to some frequently asked questions about monitor troubleshooting and replacement:

Ques 1: How can I test if my monitor is broken?

Ans: Connect your monitor to another computer.

If the issue persists on a different device, your monitor is likely the problem. Check for visual artifacts, dim images, flickering, and other symptoms.

Ques 2: What’s the average lifespan of a monitor?

Ans: Most LCD monitors last 3-5 years on average with regular use. High-end gaming or professional monitors may last 5-7 years.

Signs like dimming and burn-in indicate a monitor is nearing the end of its usable lifespan.

Ques 3: Is it worth repairing an older monitor?

Ans: For standard consumer monitors, repair costs often exceed the price of a new display.

Component-level repairs for monitors are time intensive. Replacement makes more sense unless it’s an extremely high-end monitor.

Ques 4: Should I buy the same monitor again when replacing?

Ans: It’s up to you. Getting the same model can provide consistency. But you may want to look at newer monitors for better features and performance.

Avoid models known for reliability issues. Do research to find monitors best suited for your needs.

Ques 5: Can I trade in my old monitor anywhere?

Some electronics retailers offer trade-in programs where you can bring in your old display and get credit toward a new one.

Stores like Best Buy offer this. Otherwise, you can sell functional monitors on sites like eBay.

Ques 6: What’s the difference between a monitor dying vs. sleeping?

Sleep mode turns off the monitor temporarily, but it can quickly wake.

A dying or dead monitor has hardware failures and won’t show an image at all or has visual artifacts. Signs like strange noises also indicate a dying monitor.


With age, all monitors will eventually fail. But being aware of common warning signs like image distortions and burn-in can help you identify problems early.

First, troubleshoot cables, connections, and software before replacing your display.

Monitoring repair sometimes makes sense, but replacement is often the better value.

With regular maintenance and proper handling, you can maximize the lifespan of your monitor.

If you notice persistent issues emerging, just be prepared to buy a new one.
