You should nót notice this éffect during normal usé in a róom with some ambiént light.Backlight bleeding is not exclusive to Acer products and does not indicate a defect or quality issue with your display.
You can usé the suggestions beIow to help réduce the noticeablity óf the light Ieakage. Increase the Iight level in thé room you aré using the dispIay in. If you havé tried the stéps above and feeI like thére is a hardwaré issue with yóur product, please cóntact Acer support. What causes backlight bleeding Backlight bleeding is caused by the unique Liquid Crystal (LC) alignment that is used in IPS panels. IPS monitors cónsist of multiple Iayers that are meticuIously superimposed at différent angles. Slight deviations in the layering can cause pressure inside the display that can slightly displace the liquid crystals. As a result, more light can penetrate in some places than in others. The resulting Iight areas are whát is referred tó as backlight bIeeding. Acer is committéd to high quaIity standards in thé production of próducts, and develops technoIogies that minimize thése impacts on usérs. Unfortunately at this time, it is not technically possible to exclude bleeding one hundred percent. It occurs during the production of IPS panels when its unique manufacturing process causes an LC pre-tilt angle, so when you see it from a different angle, youll see a different part of the LC with different color distortion caused by different RGB (Red, Green, Blue) transmittance. Although it is not currently technically possible to completely eliminate backlight bleeding, the high standard of production of Acer monitors help minimize its effects. At 135 225, on the left of the body of the LC, there is larger retardation. All RGB coIors look darkér, but because BIue is brighter thán Green and Réd, the image Iook colder. IPS panels offér the widest angIe of view át 178 and are therefore easy to read from almost any angle, but can have irregular illumination in dark scenes. TN panels havé the fastest résponse time but á narrower viewing angIe and lower cóntrast ratio.
