Glare on the monitor

Often, many users experience an unpleasant problem. When purchasing a new monitor or TV, after some time or immediately, a specific glow appears on the screen. It is especially visible if the image on the monitor or TV is dark. Many believe that this is a factory defect, however, users often encounter the fact that the seller does not include this problem in the list of warranty or critical faults and refuses to repair it. What to do in this case will be discussed in this article.

What does glare look like on a monitor?

First you need to determine what exactly is “light” on a monitor or TV. The easiest way to determine this malfunction is to open a black image on the screen. After which the user can see a glow from one or more points along the edges of the screen. These are “lights”. Malfunctions can also be seen if you put the device in demo mode and completely turn off the lights in the room. In this case, the user is given the opportunity to detect any malfunctions or errors in the operation of the screen.

Attention! The device should be checked for glare or other malfunctions in a dark room, since the presence of third-party light sources can create glare, which will not allow the user to fully evaluate the performance of the screen.

Causes

This problem is typical for LCD monitors due to the specifics of their operation. The display of colors is achieved through special crystals that move. They are constantly illuminated by a special backlight, which is either a lamp or a series of LEDs (depending on the technology of the TV). Thanks to this backlight, the image on the screen changes color and brightness.

Due to incorrect tilting of the LCD crystals or changing the position of the lamp, the light from the backlight is reflected from the surface and becomes visible to the user. Due to the fact that the matrix can move away from the screen at different distances, glare can be either strong or barely noticeable. Also, the glow from the lamps can be either simply light or colored, which makes using this screen less comfortable.

How to get rid

Basically, most manufacturers recognize this malfunction and can replace the device only if the monitor has not been exposed to external influences and has not been disassembled.

Important! To avoid such situations, you should always check the image quality in demo mode before purchasing. If a store refuses to connect a device to the network, you should think about the reasons for such refusal.

If it is not possible to take the device to a service center, there are several ways to fix this problem at home.

Attention! Please remember that improper handling or excessive force may damage the screen.

1. The easiest way to remove glare is to lower the brightness and contrast in the monitor settings. This method will help if the highlights are weak and cover only a small area.This does not solve the problem technically, however, it will help get rid of the malfunction and increase the comfort of use..
2. The second method is more effective. It is necessary to “stick” the matrix back to the surface so that the light again passes only through the crystals. To do this, you need to take a lint-free towel and, leaning it against the screen, lightly press it with your hands in the places where the light glows. This should be done carefully, but firmly, as there is a risk of damaging the surface of the monitor. Then, with effort, you should smooth out the highlights in the corners. This “massage” should be carried out in a dark room on a working screen, on which there will be only a black image. This will allow the user to observe the result of their work.
3. For the third method, you first need to warm up the matrix. To do this, leave the device turned on for 2-3 hours. After this, you need to carefully take the monitor and tilt it towards you until it is almost horizontal. Then “shake” it around the corners. After this, the glare should disappear.
4. The last method is the most unsafe, so it is not recommended for users who have little knowledge of technology. This method will require a screwdriver. The user needs to unscrew the monitor cover and then screw it back. Perhaps the problem is that the screen does not fit tightly enough to the body.

Attention! Many of the bolts that secure the mount have special seals, and if they are broken, warranty service for the device becomes impossible.

Listed above are the main ways to eliminate glare on a monitor screen. If none of them help, then you should seek professional help from a service center, where specialists can help fix this problem.
