A pixel, short for picture element, is a single point in a graphic image. LCD devices display pictures by dividing the display screen into thousands (or millions) of pixels, arranged in rows and columns. The pixels are placed close together so that they appear connected. A full pixel is a combination of one red, one green, and one blue subpixel.
A full-pixel defect is a bright white dot or a noticeable black dot on the display.
A subpixel defect is also called as a dot effect.
During the LCD manufacturing process, it is not uncommon for one or more subpixels to get into an unchanging state, causing a bright or dead pixel. A display with 1 to 5 fixed subpixels is considered normal and within industry standards.
A subpixel remains permanently on, resulting in a white or colored dot on a black background. Bright pixels can be white, red, blue, or green and visible on a black background.
A subpixel remains permanently off, resulting in a black dot on a white background. Dead pixels are visible on any background color, except on a black background. Dark subpixel defect is also called as dead subpixel defect.
Dell offers a Premium Panel Exchange that ensures zero bright pixel defects on select Dell Consumer, Professional, UltraSharp, and Gaming monitors, including Alienware monitors.
Defective pixels do not necessarily reduce the performance of the monitor. However, they can be distracting, especially if the pixels are in positions where viewing quality is reduced.
Unyielding commitment to quality and customer satisfaction has driven Dell to offer a Premium Panel Exchange as part of the standard limited hardware warranty. Even if one bright pixel is found, a free monitor exchange is supported during the limited hardware warranty period.
Premium Panel Exchange is available for select Dell Consumer, Professional, UltraSharp, and Gaming (including Alienware) monitors sold with computers or as stand-alone units, with a standard 1-year or 3-year limited hardware warranty. Customers who purchase an optional extended warranty benefit from this coverage during the limited hardware warranty period.
The pixel policy that applies to your device varies across each model. See the tables below to learn about the number of bright and dark subpixel defects that are allowed. If the number of defective pixels exceeds the applicable numbers in the tables below during the warranty period, contact Dell Technical Support for assistance.
