Acer Monitors and Laptops
What is the Acer policy on defective or stuck pixel on my LCD display?
LCD displays are made up of a set number of pixels and each pixel is made from 3 sub-pixels - one Red, one Blue and one Green. Each sub-pixel has its own transistor, which makes manufacturing the glass substrate very complex.
Due to the nature of the manufacturing process, occasional defects can occur. Pixel defects or failures cannot be fixed or repaired and can happen at any stage in the LCD’s life. There are two types of pixel defects:
- Bright Sub-Pixel: A sub-pixel is displayed as a small white dot on a black pattern.
- Dark Sub-Pixel: A sub-pixel is displayed as a small black dot on a white pattern.
The table below shows the allowable number of dead sub-pixels for the native resolution of the LCD panel. Your display can be replaced during the duration of the limited warranty period if the number of dead pixels is greater than the allowable number.
General Policy:
| Native Resolution | Bright Sub-Pixel | Dark Sub-Pixel | Total Sub-Pixel |
|---|---|---|---|
| SXGA (1280*1024) | ≤ 2 | ≤ 5 | |
| HD (1366*768) | ≤ 2 | ≤ 5 | ≤ 5 |
| HD+ (1600*900) | ≤ 2 | ≤ 5 | ≤ 5 |
| FHD (1920*1080) | ≤ 2 | ≤ 5 | ≤ 5 |
| SXGA (1280*1024) | ≤ 2 | ≤ 5 | ≤ 5 |
| WUXGA (1920*1200) | ≤ 2 | ≤ 5 | ≤ 5 |
| WFHD (2560*1080) | ≤ 2 | ≤ 5 | ≤ 5 |
| QHD (2560*1440) | ≤ 2 | ≤ 5 | ≤ 5 |
| WQHD (3440*1440) | ≤ 2 | ≤ 5 | ≤ 5 |
| WQHD+ (3840*1600) | ≤ 2 | ≤ 5 | ≤ 5 |
| UHD (3840*2160) | ≤ 2 | ≤ 5 | ≤ 5 |
Premium Model Policy:
| Professional Monitor | Bright Sub-Pixel | Dark Sub-Pixel | Total Sub-Pixel |
|---|---|---|---|
| BM Series | 0 | ≤ 5 | ≤ 5 |
Note:
1. A sub-pixel, less than or equal to 0.5 of a sub-pixel, is excluded from the warranty.
2. Warranty duration and product specification may vary from different regions. Please contact local distributors/dealers for further information.
ASUS Monitors and Laptops
LCD panels are made up of millions of micro electronic pixels. If one pixel is no longer lit, it will become a bright or dark pixel. By ISO 13406-2 standards, ASUS conforms to the acceptance spot level which lies between 3 to 5 bright/dark pixel defects. In order to deliver ultimate vision experience to you, panels that contain less than or equal to the above number of spots, then it is considered an acceptable LCD monitor. Please refer Bright/Dark Spot Acceptance Detail below:
- Total combined bright and dark sub-pixel defects (5 max)
| If you have... | Then |
|---|---|
| 4 bright dots, 0 dark dots | Your monitor qualifies for RMA |
| 2 bright dots, 2 dark dots | Your monitor is functional |
| 2 bright dots, 4 dark dots | Your monitor qualifies for RMA |
| 0 bright dots, 4 dark dots | Your monitor is functional |
| 0 bright dots, 6 dark dots | Your monitor qualifies for RMA |

Dell Monitors
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 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.
Dell offers a Premium Panel Guarantee that ensures zero "bright pixel" defects on Dell UltraSharp, Professional, and 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 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 computers or as stand-alone units, with a 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.
Monitors or laptop LCD panels are subject to replacement depending on criteria that are outlined in Table 1 and Table 2.
| Dell Monitor | Bright Subpixel | Dark Subpixel | Total Subpixel |
|---|---|---|---|
Flat-panel monitors with Premium Panel Guarantee:
|
1 or more | 6 or more |
|
| Dell monitors (D series) | 6 or more | 9 or more | Combination of bright and dark subpixel = 9 or more |
OLED panel monitors with Premium Panel Guarantee.
|
1 or more | 13 or more | Combination of bright and dark subpixel = 13 or more |
