This defect means uneven illumination of individual sections of the display. It can be clearly seen on the black image with the lights off. Basically, this flaw can create problems when watching videos or in computer games where there are darkened scenes.
IMPORTANT. Established sanitary standards limit the total area of exposed areas: not more than 20%. It is possible to measure the value on special equipment (it is available in service centers).
The reasons for the appearance of light
Possible sources of the problem:
New monitors, when connected for the first time, may produce uneven brightness, which disappears after a few days of use.
Features of LED products, they are designed in such a way that the LEDs that provide lighting and brightness are located on the edge of the monitor. In this regard, brighter areas may appear at the edges.
Limited viewing angles can cause the imaginary effect of incorrect illumination. This often happens when using models with a large diagonal, when the user changes position relative to the monitor.
Possible defect or breakdown of the screen if large-scale violations of uniform illumination are detected.
According to experts, all models of LCD screens are more or less susceptible to such shortcomings.
ON A NOTE. If the backlight appears on the screen after a long period of use, there is a problem requiring repair.
Is it possible to get rid?
Methods that the user can apply independently are reduced to changing the settings:
- If you increase the brightness and contrast levels of the monitor, the light will become invisible or disappear.
- On models of some manufacturers (for example, Sony), you can select the corrective Cinema setting, which creates an image with a warm color. To do this, press the Options key on the remote control and activate "Select a scene", and then apply the desired item.
- If the monitor has the function of dynamic control of the LED backlight (LED Dinamic Control), make sure that it is on, it can be used to adjust the necessary lighting levels.
ATTENTION. According to consumer reviews, in many cases, displays with dimmed lights are agreed to be exchanged by stores within 14 days. After this period, you will have to contact the service center. Therefore, when buying a monitor, require a full test of its operability.
