When a display has a dead pixel, whether it is necessary to replace it depends on the type of dead pixel and the degree of impact on the user experience, which I will explain in detail below.
Dead pixel type: The dead pixel of a display can be divided into two types: bright spots and dark pixels. Bright spots are dots that appear bright white or colored on the screen, while dark dots are dots that appear black on the screen. A single or small number of dead pixels may not seriously affect the user experience, but if there are continuous or large areas of dead pixels, they can be noticeable and may interfere with normal use.
Dead pixel location: The location of the dead pixel on the screen also affects the decision to change the screen. If a dead pixel appears in a relatively inconspicuous location, such as the edge or corner of the screen, it may be less intrusive to the user experience. However, if a dead pixel is located near the screen** or common operating area, it may interfere with the normal use of the software** or other work.
Quantity and density: If the display has only one dead pixel and is in a location that is not used frequently, it may be tolerated and continued to be used. However, if there is an increase in the number or density of dead pixels, especially in ** or frequently used operating areas, this can have a significant impact on the visual experience.
Stability of dead pixels: If dead pixels are stable, i.e. they always remain in the same position and state on the display, they may be able to adapt and be considered part of the display. However, if the dead pixels are flickering, changing position, or spreading, this could indicate a more serious problem with the display, and it is recommended to consider replacing the display.
Warranty and Repair Policy: If the monitor is still under warranty and the dead pixels are covered by the warranty, you can contact the manufacturer or seller for repair or replacement. Outside of the warranty period, if the dead pixels affect the user experience, you can consider consulting a professional repair service provider or purchasing a new monitor.
In summary, when there is one or a small number of dead pixels on the display that are not obvious, and the impact on the user experience is small, you can continue to use it. However, when the number of dead pixels increases, the density is high, or when dead pixels appear in common operating areas, it is recommended to consider replacing the display to ensure a good visual experience.
