Every electronic device has a specific life and needs to be replaced from time to time. Monitors are no different in this regard and will eventually start deteriorating as time goes on.
Now, you could go about replacing individual components of your monitor to keep it running for a longer period of time, but in order to do that, you need to know exactly what the problem is and which component seems to be causing it.
This is exactly why we’ve come up with a list of the 9 most common signs that will tell you if your monitor is dying, in addition to pinpointing the exact component from which the fault originated.
Knowing and recognizing these signs will also allow you to estimate your current monitor’s life and take action to make sure it doesn’t completely die. So, without any further ado, let’s get straight into it.
The 8 Most Common Signs that your Monitor is Dying or Not
The Main three reasons why monitors fail or dying are heat, power and age.” All monitors produce heat as they work, and the older the monitor, the more heat it will produce. Over time this can cause damage to the monitor’s components.
The following 8 signs will tell you whether your monitor is dying or not.
1. Flickering Images
Screen or image flickering is a problem that even the more modern LED and LCD screens have to contend with, in addition to the older CRT screens.
Basically, if you start noticing the screen flickering or blinking at a continuous rate and more frequently than it did before then, it may be an early sign that your monitor is dying.
Now, unlike most of the other faults in this list, image flickering can occur due to a number of reasons. The most likely explanation for image flickering is usually a burned-out monitor due to increased overclocking.
However, it could also be caused by an automatic change in resolution, refresh rate, or a corrupted graphics card, in which case you’d have no option but to change your screen completely to stop your monitor from dying.
2. Overall Dimness of the Screen
Dimness is a sign that almost no monitor user notices unless especially informed as the monitor starts getting naturally dimmer as time goes on at an incredibly slow rate.
Eventually, the monitor’s screen shuts off completely, leaving users perplexed as to the cause of this seemingly new issue.
Thus, it is incredibly important for every monitor user to pay special attention to the brightness of their monitor’s screen, as the overall dimness of the screen could be another sign that your monitor is on its last legs.
It’s also incredibly important to catch this sign very early on, as continually viewing a dim screen can lead to eye fatigue and badly affect your eye health in general.
Now, in most cases, this dimness is caused by the backlight of your LED or LCD monitor failing at a continuous rate which eventually results in the dimness being permanent.
However, before concluding that it’s the backlight’s fault, do be sure to check out the drivers, graphic card, and RAM for any deterioration, as these could also impact the overall dimness of the screen.
3. Taking too Long to Boot up
Another sign that most users waive off as just a random occurrence is when their monitor takes too long to boot up.
When in actuality, this should be a source of great concern as your monitor’s boot-up time is directly linked to its overall life.
Modern LED and LCD monitors should ideally take 5 to 10 seconds to boot up completely, whereas older CRT monitors can take up to 15 seconds, but if your monitor is taking even longer than that, then you should recognize that as a problem.
Some users who’ve had the same monitor for a number of years now should understand that this issue could simply be occurring because their monitor’s life is reaching its end and should prompt them to replace their existing monitor immediately.
However, the most likely cause is that the capacitors of your monitor have run out of juice and need to be replaced either by you or, more preferably, a professional.
4. Frequent and Random Shutdowns
More often than not, the sign that finally tips users off to their monitor dying is when it starts shutting down randomly during use or shuts down immediately after starting up.
You’ll also notice that your monitor stops responding to button presses, and it becomes pretty difficult to turn the monitor back on.
However, knowing about the problem itself is not enough to solve it; you must also know how to solve it. Most panicked users try tapping the monitor by hand or twitching the cables, which almost never works.
Instead, you may want to check out your power supply, as the most common reason for random shutdowns is power supply malfunctions which could occur due to the natural aging of electrical components or a strong power surge in the 220V.
Thus, the most obvious course of action would be to replace your older power supply with a new one, and your monitor should hopefully be as good as new.
On the other hand, the problem could also simply be overheating, in which case you’ll have to give your monitor some time to rest before you start it up once again.
5. Dead Pixels
As every monitor user should know, an LCD or LED screen is made up of millions of pixels that are responsible for displaying images on the screen and changing their color according to what needs to be displayed on the screen.
As a monitor continues to age, some pixels may end up going blank or ‘dead’, which basically means that these pixels refuse to display the image on the screen and instead turn to a constant black color.
Thus, if you’ve noticed even a single pixel going blank, then there’s a high chance that your monitor’s living its last days.
In some cases, monitors continue to function regularly even if they have to contend with one or more dead pixels. However, knowing if your monitor’s dealing with a dead pixel is still incredibly important as it’s a direct indicator of your monitor’s life.
There are plenty of online resources that can catch and tell you the number of dead pixels on your screen, so make sure you make use of them if you aren’t able to spot any of them yourself.
6. Vertical Lines
One of the most obvious signs that your monitor is on its last legs is the sudden appearance of single or multiple vertical lines on the screen.
In some cases, users may even notice the sudden appearance of some distorted colorful patterns, which signify almost the end of your monitor’s life and need to be serviced immediately, if you want to save your monitor.
The component that’s commonly linked with lines appearing on the screen is your monitor’s graphic card or driver, in which case you’ll have to check and update your graphic driver settings or replace your existing graphic card.
On the other hand, the vertical lines could also be caused by a faulty display panel, in which case you’ll have to replace the entire panel (which is almost as expensive as replacing the entire monitor).
7. Increase in Monitor Noise
When the monitor is operating normally, many users would have noticed that it makes a small amount of noise, especially during its first boot up.
This is completely normal and is usually the result of the graphic cards and fans activating inside the machine.
But, if you start noticing a gradual increase in the amount of noise with every bootup, then it could mean that your monitor is on its last life and should be dealt with immediately.
In our experience, the most common cause for an increase in monitor noise is due to a faulty VGA cable or a PC video card without an EMI suppressor.
The solution is a pretty simple one as well, you just need to replace your existing cable with a better quality cable that comes with an EMI suppressor, and your monitor should be good to go.
8. Distorted Images
We’re pretty sure all of the monitor users reading this would know what image distortion is and how much it can negatively affect your eyes.
However, what you didn’t know was that image or screen distortion could also signify the end of your monitor’s life in the most extreme cases.
Most of the time, screen distortions can occur due to a loose cable or the presence of a magnetic object close to the screen.
However, in some cases, image distortion can also be caused by a bad graphic card or driver and, if left unchecked, could result in the permanent death of your monitor.
Thus, it’s incredibly important that you check and update your graphic drivers on a regular basis and invest in better wiring to save your monitor from this fate.
What to Do?
Whenever you notice any of the following signs that your monitor is dying, it is time to take action. You need to replace it or hire a good technician to help identify the problem and provide helpful advice.
So, there you have it, folks; that was a list of the 8 most common signs that will tell you if your monitor is dying.
Now, we know that ‘dying’ is a pretty big word and has some huge implications, but we’re here to tell you that most of the signs and faults in this list can be easily dealt with by replacing one or two components in your monitor so you shouldn’t worry too much even if you do notice one or two of them.
Just make sure you check out your monitor thoroughly once you come across one of these signs and pinpoint the exact components that are faulty and should be replaced.
Unfortunately, in some cases, you may come across more than one of these signs and would be better off replacing your entire monitor, but that’s a risk you have to take when buying an electrical product.
