How Much Backlight Bleed is Acceptable? — Everything You Need to Know

Backlight bleeding is a common defect that is likely to be observed in LCD or LED monitors. The issue occurs because of the construction of the monitor.

The LCD and LED monitors are built with a backlight panel that provides light for color reproduction so that visuals can be produced on the display. Sometimes, this backlight leaks around the edges and causes backlight bleeding.

The backlight bleeding is visible from the edges and may or may not affect the visuals on your display. The intensity of backlight bleeding decides whether or not you should accept it.

So, in this article, we will discuss in detail how much backlight bleed is acceptable and what you should do in case it gets out of those limits.

Backlight Bleeding Intensity


The backlight bleeding intensity is determined by conducting a backlight bleeding test. The test can be conducted using a wide range of simple methods.

You can conduct a backlight bleed test by opening a pitch-black image on your monitor. The image must be opened in full screen. Adjust the brightness to medium and observe the backlight bleeding.

If you can observe minor backlight bleeding, then you have nothing to worry about. However, if the backlight bleeding becomes visible even without the test, then you have to take measures to resolve the issue.

You can also conduct this test by using a pitch-black video in full-screen mode. There is also a variety of online tools that allow you to conduct this test.

Always Conduct Backlight Bleed Test on New Monitors

Backlight bleed is not acceptable in new monitors. The issue might surface once your monitor gets old, but you cannot accept living with a new monitor that has a backlight bleed.

Hence, whenever you purchase a new monitor from the store or online, you must immediately conduct a backlight bleed test.

If there is any backlight bleeding, you can ask for a free replacement or full refund depending on the policy of your monitor’s manufacturer.

However, if your monitor gets old and is no longer covered by the warranty, then a backlight bleed issue has to be dealt with using other methods.

Does Backlight Bleeding Intensity Increase?

Whether or not your monitor’s backlight bleeding intensity increases depends on your usage of the monitor. If you use the monitor carefully and take certain precautions, you can prevent the backlight bleed from increasing.

Minor backlight bleeding is common and acceptable. You will only be able to observe it if you conduct a backlight bleed test and it will not be visible on a normal display.

Hence, you will be able to play games, watch movies and work on your tasks without the backlight bothering your visuals.

However, if the intensity increases, the backlight will become worse and will distort the visuals on the edges of your monitor.

You will have light leaking from the edges, which can become very inconvenient and will force you to replace the monitor. However, we recommend that you try a few fixes before you go for a new monitor.

Not to be Confused with IPS Glow


Backlight bleeding is often confused with IPS glow which is very different from the issue. IPS glow occurs only in IPS monitors while the backlight bleeding is a defect for all LED and LCD monitors that have backlight panels.

The IPS glow only occurs in the corners of the monitor while the backlight bleeding occurs in the edges and might be present in form of patches on larger monitors. However, the backlight does not bleed from corners.

The IPS glow changes its intensity when observed from different angles. It might be visible from one angle, while invisible from the other. However, the backlight bleed is consistent and remains the same from all angles.

So, you must never confuse backlight bleeding with IPS glow. Backlight bleeding is a defect while IPS glow is just a drawback of IPS panel displays.

How to Keep Backlight Bleeding at an Acceptable Stage?


You can prevent backlight bleeding from intensifying by using some precautionary measures. These measures will allow you to even reduce the backlight bleeding and maybe diminish it completely for some time.

First of all, you must use the monitor at moderate level brightness. Lowering the brightness of your monitor can allow your monitor to heal and reduce backlight bleeding. So, if you are facing backlight bleeding, consider lowering the brightness.

Secondly, you must allow the display to cool down every once in a while. The backlight bleeding occurs when you have heated up the display with consistent usage and not turned it off even when not used.

So, give your monitor a rest every once in a while and turn it off so the panels can cool down. You can also improve the airflow to the monitor, and keep it under the AC or fan so it can remain cool and does not overheat.

You can also take a microfiber cloth and rub the monitor gently around the edges to reduce backlight bleeding. Remember not to use too much force or you might end up causing more harm to the panels.

Never punch, press or force push the panel of the monitor to fix the backlight bleeding. Pushing it roughly and applying pressure at the edges will only cause more harm to the panel and increase the backlight bleeding.

Has Backlight Bleed gotten worse?

If the backlight bleed has gotten worse and is apparent even without the backlight bleed test, then you have no other option but to replace the monitor.

As your monitor is no longer covered by warranty, you will have to get a new monitor. Remember to check it for backlight bleed upon the purchase.

However, before you go do that, there are a couple of unconventional methods that you can try as your last resort.

First of all, you can try loosening the screws at the back of the panel. For that remember to turn off the display beforehand so that your monitor can cool down before you loosen the screws.

If that does not work, then you can use electric tape at the edges of the panel. To do that, you will have to dismantle the whole display and apply electric tape at the edges of the panel.

Although these solutions are not guaranteed to help, they might save you the cost of a new monitor for a little longer. No harm in trying than when you have no other option left.

Don’t Want Backlight Bleeding at All? Get OLED Monitors

One of the modern innovations in monitor manufacturing is the OLED monitors. The OLED monitors are the newest and most expensive monitors in the market that do not use a backlight panel.

The organic light-emitting diodes have the light of their own to produce the colors with the light. So, there is no backlight panel which means there will be no backlight bleeding.

However, the OLED monitors are new and very few models are available on the market. These models are highly expensive so only people who need high-grade professional performance or gaming are going for these monitors.

Frequently Asked Questions

  1. What has considered a normal backlight bleed?

    Backlight bleeding is a common defect that occurs in almost all LCD and LED monitors. The issue is minor and not observable without a backlight bleed test. If you can only observe it with the test, and not without it, then it is considered normal.

  2. Is backlight bleeding a big issue?

    If the backlight bleed gets intense, it will be considered a big issue because there is no solution to fix the problem. However, you can use certain methods to reduce backlight bleeding. We have discussed those methods in detail in the above guide.

  3. Is LED backlight bleeding normal?

    Yes, LED backlight bleeding is normal and can be observed using a backlight bleed test. However, if the backlight becomes visible even without the test and starts hindering the visual performance of your monitor, then it is not normal.

  4. Does backlight bleed go away?

    Well, there are certain methods you can use to reduce it and diminish it but there is no sure method to make it permanently go away. The flaw comes with the structure of the panels that use a backlight. You can get OLED monitors to avoid the issue.

  5. Do all monitors have backlight bleeding?

    No, not all monitors. Only LCD and LED monitors have backlight bleeding issues. The modern OLED monitors do not suffer from this issue because they do not use a backlight panel.

Some Final Words

Backlight bleed is a common defect in LCD and LED monitors. However, the intensity of the backlight bleed is a big factor. Up to a certain limit, the backlight bleed is acceptable. That is if the backlight bleed is not visible without the specific test and is not hindering the visuals on your display. However, if it gets intense, it will no longer be acceptable. We hope the guide is helpful. Good Luck!
