What you may be seeing is one or more of the greater than 2,000,000 dots that make up the composition of the LCD or OLED screens. These dots (also known as pixels) may appear red, green, blue, white, or black.
High-precision technology is used to manufacture these LCD/OLED displays to maintain a high standard of operation. But with all LCD/OLED screens, regardless of manufacturer, there may be a small number of pixels that do not change color. This is a normal occurrence for all LCD/OLED displays from all manufacturers and inherent to the technology. Most of the time, these pixels stay on the screen but are noticeable only while an all-white or all-black picture is shown, and should not be noticeable during normal viewing conditions.
If you are affected by this phenomenon and are concerned because the amount or positioning of such pixels is noticeably disrupting your viewing experience,  Contact the Product Support team .
- Some pixels can appear dead or defective if there is debris on the screen. Clean the screen thoroughly with a soft dry cloth to confirm whether or not the issue is actually a dead or defective pixel or due to just dirt or debris.
- Sometime these dead or defective pixels will correct themselves over time.
