What is Backlight Bleed? How to Reduce it with 3 Tips

If you already use an IPS monitor or recently purchased a Gaming monitor. You may find there are some flashes of lights coming from the edges of the monitor.

You may be worried if your monitor is good or has some defect.

In this post, I would resolve your query and explain the backlight bleed you see on your monitor. Also, you will learn how to reduce the backlight bleed.

Let’s get started!

What is Backlight Bleed?

backlight bleed

Backlight bleed is the phenomenon of light coming through a display from behind, typically at the edges. It’s most often seen on LCD screens, and it can be distracting to the viewer and cause damage to parts of your display.

Backlight bleed is a problem caused by the poor construction of the LCD panel or, more commonly, improper installation. It’s not just your TV that suffers from backlight bleed. The same thing occurs with computer monitors and laptop displays.

During the identification, you may doubt if the problem is backlight bleed or IPS glow. You can check more details about IPS Glow vs Backlight bleed here.

Types of Backlight Bleed

The types of backlight bleeding are:

  1. Flashlighting: the light is brighter on one side of the screen and barely visible on the other. This can be a result of improperly installed LCD panels.
  2. Clouding: the light is more visible at a certain point on the screen, typically near one edge. This can be caused by poor construction and improper installation of LCD panels as well.


Flashlighting is the most common type of backlight bleeding, and it’s typically caused by improper installation. This can be due to incorrect placement or a lack of airflow in your device enclosure. 

If you’re experiencing this issue with your LCD display, three things might help:

• Make sure no objects are pressing against the screen on the back of your TV

• Use anti-reflective material and a matte screen protector to reduce reflections from ambient light

• Install some ventilation systems in your device enclosure.


Clouding is the second most common type of backlight bleeding, and it can be caused by poor construction. You might have a problem with your LCD panel if you’re experiencing clouding or a shiny border around an edge-lit display. 

Two things might help when this happens:

• Replace the panel with a higher quality one

• Install an anti-reflective material for the screen to reduce reflections from ambient light.

How to Prevent Backlight Bleeds?

To prevent backlight bleed, you need to make sure that your LCD panel is installed as carefully and precisely as possible.

This means making sure all of the connections are correct and not too tight, that the panel is flush with the rest of your device enclosure, and that it’s in an area where there isn’t any ambient light.

The best way to avoid backlight bleed is by making sure you get a high-quality LCD screen at the start. It pays off in the end when you don’t have to worry about side effects like clouding.

Avoid cheap screens that are low quality because they’re more likely to suffer from backlight bleed problems as well as other issues down the line.

How to reduce Backlight Bleeding?

In this post, we’ll show you three ways to reduce backlight bleed and make your screen more enjoyable for viewers.

  1. Tip #01: Reduce the brightness of your monitor to an acceptable level. This will be more difficult in a room with natural light, but it’s worth doing because you’ll reduce the amount of backlight bleed creeping through from behind your screen.
  2. Tip #02: Change up how you place your display on your desk so that there isn’t an excessive amount of light coming off the back.
  3. Tip #03: Purchase a screen protector for your monitor to reduce glare on display, which will also help with any ambient light that may be causing bleeding from behind.

How do I perform a Backlight Bleed Test?

If you’re not sure if your TV has a backlight bleed, do this simple test:

• Turn off the lights in your room and turn on the TV. This means all light sources should be coming from behind it and shining through to your eyes.

• Look at a dark area where there’s no text or images on the screen.

• If you notice a bright streak or glowing coming from behind your TV, then it’s likely suffering from backlight bleed problems that need to be fixed before they get worse.

Does backlight bleed affect picture quality?

Backlight bleed is more of an annoyance than a problem that will affect the quality of your display. It can cause some streaking, but it’s not permanent and doesn’t have any effect on how well you see what’s on the screen.


Here, I have discussed a lot about the backlight bleed technology for your monitor. I hope you understood in detail about the backlight bleed and it is a manufacturing defect that sometimes comes with monitors and TVs.
