High-precision technology is used to manufacture these LCDs to maintain a high standard of operation. However, in all LCDs, there may be a small number of pixels that do not change color. This is a normal occurrence for all LCDs from all manufacturers. Bright or dark spots may be more prominent while viewing an all-white or all-black screen, but are often not noticeable under normal operation.
NOTE: A replacement LCD may exhibit the same characteristics or have pixel issues in a more noticeable position than on the display it is replacing.
