9 Most Common Problems with LG Monitor (with Solution)

LG is a family-owned South Korean multinational corporation specializing in producing highly innovative electronic products, that are committed to helping customers’ lives more comfortable.

However, even though the company aims to bring value to its users’ lives, the consumers might still inevitably experience daily problems.

List of Common Problems with LG Monitor

Though LG monitors seem uncomplicated because of their thin appearance, many can still go wrong beyond its facade.

To help LG users troubleshoot monitor problems, listed below are the common ones and how to fix them.

1. The monitor does not work

Monitors that won’t work are the implication of many issues that exist. To help you diagnose the real issue and avoid further problems, following the guide below will help you fix the hassle troubles.

Monitor incorrectly connected

First off, the user must ensure no physical monitor defect. To do this, check if the monitor is on an energy-saving mode.

LG Monitors typically displays on its screen even though it may seem off, but a light indicator is placed on the model. Pressing the monitor’s power button will help fix this situation.

Faulty Monitor’s Power Cable

If everything seems to be working fine with your monitor, the fault may now arise from the monitor’s power cable.

To ensure that the confirmation of the issue will be done safely, you can contact LG for a power cable replacement.

2. Monitor only displays the ‘No Signal’ message

When your plugged-in LG monitor displays the ‘No Signal’ warning message, you may have bumped into this issue.

When the situation is already bothersome, you’ll know how to troubleshoot by reading more below:

Damaged Video Cable

If the video cables seem hopeless to use, try replacing them with VGA, Display Port, DVI, or HDMI as a temporary alternative since most monitors use this as a standard.

Graphics Card problem

This problem typically happens when your driver is outdated. To fix this issue, check if your graphic card has multiple ports. With this, you can verify if the problem only lies on your graphic card’s port.

If you have verified that the graphic card has a failing port, you can move the cable to another port slot instead.

3. LG Monitor is blinking or flickering

A blinking monitor is one of the most hassle things that can go wrong with your LG Monitor.

Not only can they hurt your eyes, but the continuous flickering seems to be irksome as well, especially when you are working on a crucial project.

Find out how to manage flickering LG monitor below.

Loose Video/Power Cable

Track down if there are loose cables at the back of the monitor, as loose ends interrupt the smooth flow of information delivery.

Loose video cables are an easy fix. To do so, tighten the video cable connected both on the monitor and the system unit to ensure loose cables are left.

Defective Video/Power Cable

If tightening the cables seems not working, you may conclude that the video or power cable is already malfunctioning.

However, a repair won’t help in this scenario because the only option left for you is replacing the damaged cable.

Improper Refresh Rate

Not only cables can cause flickering monitors but also incorrect refresh rates.

Refresh rates are the number of images that will be sent from the CPU to your monitor in a matter of seconds, and they are expressed in hertz.

To change the refresh rate into a suitable fit for your monitor, right-click into display settings > display adapter properties > monitor > screen refresh rate.

Note that in spotting the proper refresh rate, updating your computer driver may help.

4. Black/Colored Vertical Lines

Vertical lines can cause a nightmare, particularly for first-time desktop owners.

Worry no more because as nightmarish as they seem, you don’t have to panic about it.

Trace where did these lines arise for you to troubleshoot this issue quickly:

Hardware Failure

First, you can observe the following steps to ensure that software issue does not cause the vertical lines.

1. Shut down your desktop but keep the power cable attached.
2. Switch the PC on again.
3. Press F10 many times to launch the recovery environment.

If the monitor turns out to be alright after this, proceed to the ‘Software Issue’ item below.

You can confirm that the vertical lines are caused by a hardware failure when you’re already in the Basic Input/Output System (BIOS) setting, and the verticle lines are still visible.

In this case, you have to execute a hard reset and then update the BIOS.

When updating the BIOS, note that interfering with the process will cause further issues that are even more difficult to resolve.

However, if updating the BIOS frightens you, contacting tech experts would be great as this minimizes the additional damage an improper execution may give.

Software Issue

If the vertical lines did not appear in the BIOS setting, the issue arose from a software-related problem.

You don’t have to worry because this issue is more straightforward to settle. To do so, follow the steps listed below:

1. Enable the safe mode that you can access from the Startup Settings.
2. Uninstall the display adapter.
3. Verify if there are driver updates available.
4. Do not forget to disable the safe mode.

Monitor Defect

If the vertical lines persist even after the above resolutions, the problem will boil down to the physical defect of your LG monitor.

However, vertical lines caused by defects arise from the LCD panel, which is the most expensive monitor part.

If the costs of repairing outweigh the costs of purchasing a new monitor, you can resort to the latter to save up a penny.

5. Dead/Stuck Pixel

A dead pixel is a tiny dark part of the monitor, and it can be bothersome despite its small size.

On the other hand, a stuck pixel is like a dead pixel, only it does not appear a black color but is sometimes red, green, or blue.

Even though they appear tiny, users can find them pesky because they don’t match the monitor’s entire display.

Find out below what you can do about them:

Physical Malfunction

Unlike the aforementioned common monitor problems above, dead and stuck pixel occurs because of the monitor defect.

First, you might want to check if the warranty is still valid. Return the monitor as soon as possible because sometimes, stores do not replace the monitor with many dead pixels.

If the store turned you down, monitor replacement is unnecessary since the monitor is still functional despite the dead pixels. They could give you an uncomfortable feeling, but that would be all.

6. Resolution Problem

Screen Resolution refers to how clear the texts and images are displayed on your screen.

However, when the resolution displays vague images and texts, this becomes a problem.

Figure out below the possible reasons and how to fix them below:

Incorrect Resolution Setting

A resolution setting becomes improper when it doesn’t match the memory and graphics card capacity responsible for this department.

To check the recommended resolution setting and switch to them instead, follow the steps below:

1. On your Windows desktop, press right-click and choose Display Settings.
2. On display,select the drop-down menu.
3. Search for the recommended setting. However, if the problem persists, find out the appropriate setting by testing them.

Hardware Problem

Display resolution relies not solely on its software but also on the hardware that makes up the display. This hardware includes the display cables, graphics card, and the screen itself.

The problem may arise due to the incompatibility of the graphics card and display cable. Find a compatible graphics card and display cord and replace the old ones to fix the issue.

LG Monitor Pros & Cons

With all the common problems presented above, they are not enough to become a determining factor whether to buy an LG Monitor or not.

Identifying the benefits and drawbacks of owning an LG Monitor could help because they give an overview of utilizing your monitor and its set apart from the other competitors.

Not only will you know what to expect from your LG Monitor, but you can also know what your LG Monitor could not give you.

With these, detailed below are the advantages and disadvantages of owning an LG Monitor.

Pros

Ultra-Wide Models

LG 34GP83A-B is one of the ultrawide monitors that LG offer. With this kind of variant, users who particularly like to multitask will love this 34-inch, 3440×1440 resolution with an aspect ratio of 21:9.

With them being 30% more than the typical monitors with a slightly curved appearance, they could be ideal for gamers and editors to experience an immersive experience.

Immersive Gaming Experience

LG is best known for producing tech devices specializing in gaming and Variable Refresh Rate or VRR that help to stabilize and reduce buggy and unnecessary motions.

 Gaming and other computer-related works such as editing and multi-media arts can be experienced smoothly, thanks to LG’s VRR.

IPS Panel System

LG exclusively manufactures In-Plane Switching. That is why it is easy to say that their devices, including their monitors, have IPS technology—committed to revolutionizing display, organizing the orientation of liquid crystal layers between the glass substrates.

IPS mainly helps for ultrawide viewing, as it provides a substantially colored angle even in the peripheral area vision of the user.

Intertek Certified

Intertek certification assures the consumers that the product they buy is reliable. Since LG is Intertek certified, the users don’t have to worry as accreditations like this are guaranteed to be dependable. 

Cons

Restricted Ergonomics

Tech fans notice that LG seems to like producing fixed ergonomic monitors. This issue may be one of the biggest turn-offs, especially to consumers who want to adjust their monitors according to preferences.

Without the freedom to adjust the screens, the tendency is that the user will have to adjust. Some may find it a hassle and will resort to finding another brand that offers better ergonomic monitors.

Low Contrast Display

While the IPS display sounds like all rainbows and butterflies, they actually have a slight flaw. IPS tends to offer a low contrast ratio which means that the blacks may appear closer to the greyer side.

How Long Should LG Monitor Last?

Generally speaking, LG Monitors last up to 60,000 hours of use or roughly 10-20 years.

Monitors are one of the low-maintenance and long-lasting desktop parts.

However, rough estimates like this fluctuate as per different kinds of usage that vary from user to user.

Monitors like LG’s arrange the liquid crystal display with layers of polarizing material for the illumination source, which tends to deteriorate over time.

Factors that could affect LG monitor’s lifespan

Many factors could affect the life expectancy of your LG Monitor, and it is crucial to be aware of them.

Knowing the elements that could potentially reduce the longevity of your monitor can help you avoid them and take the road of lengthening your monitor’s life.

8-hour a day usage

Using your monitor in a religious time of eight hours a day can prolong it for over 30,000 up to 60,000 hours or 10 to 20 years.

These years of life are the usual lifespan of monitors.

12-hour a day usage

Using your LG Monitor for a maximum of 12 hours a day and turning the power off after would take the monitor for about 12-15 years before it bid its goodbyes.

18-24-hour a day usage

Users whose work heavily depends on a computer tend to face their screens this hour-period.

However, if you have noticed, the longer you use the monitor daily, the more it slims the possibility of its longevity.

A user can expect to be with their monitors for 3-5 years with this kind of usage.

Is It Worth Repairing an LG Monitor?

No, because unfortunately, monitor repair costs can go up to $400, straightforwardly outweighing the costs of purchasing a new monitor for only $100-300.

Unlike other tech devices, monitors tend to be one of the most expensive parts to repair because when they catch problems, it’s significant and major, most of the time.

It is indeed costly, considering that for panels alone, the costs can go around $400 already.

However, frown not because if the repairs balloon into prices like $400, purchasing a new monitor is a good deal as warranties and upgraded version guarantees come with it.
