Light leaking on your monitor edges is not only annoying but can also be distracting for gamers. Backlight bleeding is a monitor defect in modern monitors where the light source is shining through the screen edges. This defect is commonly caused when the backlight in a monitor is not completely sealed off due to poor quality control or manufacturer design issues.
Backlight bleeding commonly affects LCD display (liquid crystal display) monitors with a VA(Vertical Alignment), IPS(In-Plane Switching), or TN(Twisted Nematic). It’s not easy to spot a backlight bleed. A screen bleed is commonly visible in low light conditions, like using a monitor in a dark room.

Backlight bleeding is a display defect that commonly occurs in LCD screens that use a light source from a panel. This panel should ideally block excessive light that is not required when displaying a picture or video on the screen.
Sometimes, not all the light gets blocked by the panel, leaking out to the edges of the frame. This phenomenon is called backlight bleeding. Backlight bleeding can appear in the following ways:
Clouding is when irregular patches of light are visible when on a full black screen. This kind of backlight bleed is common with larger monitors.
This backlight bleed is visible on the edges of the monitor. In severe instances, the edges of the monitor get more light, while the center is dimmer.
Unlike your common backlight bleed or clouding, an IPS glow occurs in IPS monitors. An IPS glow manifests as a faint glow visible in certain angles, especially when watching dark content. Depending on the type of panel, the IPS glow is unavoidable but tolerable. The glow is visible in corners.
If you are unsure if you have a backlight bleed or IPS glow, you’ll need to perform a backlight bleed test. Fortunately, it’s a simple and straightforward process.
Before you perform this task, make sure your monitor is turned off. Give it a few minutes to cool off.
If you perform all the steps above and the backlight bleed persists, let your monitor sit for a day. If the bleed is still visible, repeat the above steps. The bleed should eventually fade away.
Warning: Before you perform this task, make sure your monitor is turned off. Give it a few minutes to cool off
