What Is Backlight Bleed?

It is a visual problem limited to LCDs. Most modern displays these days come equipped with LEDs on their rear side. They use it as a light source. So, when the panel is connected to a power source and is lit up the picture is displayed on the screen. However, when the light that was supposed to shine through the black screen escapes along its edges and the assembly of LCD and sensors on the backside fails to block the light completely, it results in an uneven lighting pattern on the screen commonly referred to as backlight bleeding.

Fix LCD Backlight Bleeding on PC monitor

In most cases, backlight bleeding on PC monitors is negligible and unnoticeable. You must only step in when the problem becomes difficult to bear with.

1] Unplug your PC monitor from the power source

It is not advisable to proceed with a fixing method without turning off your monitor display or unplugging it from the power source first. So, if you have your PC monitor connected to a power outlet, unplug it.

2] Loosen the screws of the frame

One of the widely known reasons for backlight bleeding is a panel fastened with screws too tight. This can lead to the display being warped. To loosen it a bit, get a screwdriver and loosen the screws gently. Too much force can break the display.

3] Bend the display frame slightly

If you notice a considerable amount of light bleeding through the edges of your PC monitor, try bending the frame after loosening the screws. This will fix the frame appropriately over the display screen and avoid any leakage of light from the edges.

4] Clean the surface in the area experiencing Bleeding problem

Take the microfiber cloth and with gentle hands rub the areas where the bleed appears in a circular pattern. Take care not to harm the screen by applying excessive force.

5] Change the angle and distance you are viewing your monitor.

Sometimes, the issue persists only at certain angles and directions. So, if the problem is not so severe, you can try to fix it by simply changing the angle and distance of your viewing. Also, you can try adjusting the height of your monitor and reduce its brightness levels.

What causes LCD Backlight Bleeding?

The incomplete blocking of the light or the display screen not being completely flat results in backlight bleeding. As mentioned earlier, the light that was supposed to shine through the screen now comes out along the edges, resulting in uneven lighting on the screen and ruining the image.

Is LCD Backlight Bleed normal?

If you’ve set your screen brightness at 100%, it is normal to experience a bit of backlighting. True 0 or NIL backlit is hard to find but a handful of expensive LCD brands claim to offer this unrealistic value. You can switch to an OLED instead.

Can Backlight Bleed go away?

Some types of backlight bleed go away by themselves. These are mostly pressure-related backlight bleeds. Also, there are ways to minimize it if it gets worse over time. This will make it slightly less noticeable.
