Dell Display Pixel Guidelines

Each pixel is made up of a red, green, and blue subpixel. When a subpixel is fixed in an unchanging state, the visible result is a tiny black, white, or colored spot that displays on the screen. There are generally two types of subpixel defects: bright and dark subpixel defects. A subpixel defect is also seen as a dot defect.

Bright pixel defect: A subpixel remains permanently lit resulting in a white, or colored dot on a black background. Bright pixels can be white, red, blue, or green and can be identified on a black background.
Dead pixel on LCD

Dark or dead pixel defect: A subpixel remains permanently unlit resulting in a black dot on a white background. Dead pixels can be identified on any background color except a black background.

Premium Panel Guarantee is premium within the industry, because it is guaranteed during the term of the limited hardware warranty to have zero pixels stuck in the "on" position—a factor that results in a bright dot on the display.

During the LCD manufacturing process, it is not uncommon for one or more subpixels to become fixed in an unchanging state. A display with 1 to 5 fixed subpixel is considered normal and within industry standards.

What is Premium Panel Guarantee?

Dell offers a Premium Panel Guarantee that ensures zero "bright pixel" defects on Dell UltraSharp, Professional, and Alienware monitors.

While defective pixels do not necessarily impair the performance of the monitor, 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 Guarantee as part of the standard limited hardware warranty. Even if one bright pixel is found, a free monitor exchange is guaranteed during the limited hardware warranty period.

Premium Panel Guarantee is available for Dell UltraSharp, Professional, and Alienware monitors that are sold with systems or as stand-alone units, and is included with the standard 1 year or 3 year limited hardware warranty. Customers who purchase an extended warranty can also take advantage of this coverage during the limited hardware warranty period.

Note: Availability of specific warranty services may vary across different regions.
