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.

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 on a black background.


Premium Panel Exchange is premium within the industry because it ensures that during the term of the limited hardware warranty the LCD Panel will have zero pixels stuck in the on position — a factor that results in a bright dot on the display.

Cause

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 subpixel is considered normal and within industry standards.

What is Premium Panel Exchange?

Dell offers a Premium Panel Exchange that ensures zero bright pixel defects on Dell Consumer, Professional, UltraSharp, and Gaming including Alienware monitors.

Defective pixels do not necessarily impair 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 Dell Consumer, Professional, UltraSharp, and Gaming (including Alienware) monitors that are sold with computers or as stand-alone units, with a standard 1-year or 3-year limited hardware warranty. Customers who purchase an extended warranty can benefit from this coverage during the limited hardware warranty period.

NOTE: The availability of specific warranty services may vary across different regions.
