Service Dead Pixel Check

Dead Pixel Check Service

Our Dead Pixel Check Service is designed to inspect a monitor before it is handed over or dispatched to help identify visible panel defects. Modern monitors contain millions of individual pixels, and a fault affecting even a single pixel can sometimes be noticeable depending on its location and the image displayed. A dead, hot or stuck pixel may not always be easy to identify during a quick visual inspection, particularly when the screen is displaying normal content. For this reason, the monitor is checked using a combination of visual inspection and specialised testing methods. This service is intended for customers who want their monitor to be inspected before receiving it and to have the screen checked specifically for pixel-related defects.

What Is a Dead Pixel?

A pixel is one of the smallest individual elements that makes up the image displayed on a monitor. Each pixel changes colour and brightness to create the picture you see on the screen. When a pixel does not operate correctly, it may remain permanently off, permanently illuminated or become stuck displaying a particular colour. These defects can appear differently depending on the type of fault and the background shown on the display. During a dead pixel check, different screen colours and testing methods can be used to make these defects easier to identify. Checking the monitor before delivery or collection provides an additional inspection of the panel beyond simply powering the monitor on and confirming that an image is displayed.

• Dead pixels may appear as dark or black points that remain visible against lighter backgrounds.
• Hot pixels remain illuminated and can be easier to notice against darker backgrounds.
• Stuck pixels remain on a particular colour and may become visible when the displayed background changes.

How We Check the Monitor

When the Dead Pixel Check Service is added to an eligible monitor order, the monitor is inspected before it is provided to the customer. The checking process is carried out in stages to help identify visible defects on the display. First, the monitor and accessible visible areas are inspected for obvious physical damage or irregularities. The display is then tested using appropriate screen testing methods and specialised software or test patterns to make potential dead, hot or stuck pixels easier to detect. Different backgrounds and colours can help reveal pixel defects that may not be visible when the monitor is displaying normal desktop content. Once the inspection has been completed, the monitor is prepared for collection or delivery.

What Is Included in the Service?

One Dead Pixel Check Service covers the inspection of one monitor. The service includes a visual inspection of the monitor and screen, together with testing of the display for visible dead, hot or stuck pixels using appropriate testing methods. The purpose of the service is to check the condition of the display panel before the monitor is supplied to you. The monitor is inspected as part of the order to which the service has been added. If you are purchasing multiple monitors and would like each display to be checked, the service must be selected for each individual monitor requiring inspection. The service applies specifically to the monitor being checked and is not transferred automatically to other products in the order.

Why Is a Dead Pixel Check Useful?

Some display defects can be difficult to notice during a normal inspection because the appearance of a faulty pixel depends on the colour and brightness of the image currently displayed. A dark pixel may be difficult to see on a dark background, while a permanently illuminated or stuck pixel may only become noticeable when the screen displays certain colours. A dedicated monitor pixel inspection uses suitable test images and methods to make potential defects easier to identify before you receive the monitor. This can provide additional reassurance for customers purchasing a new display, particularly where they want the screen to be specifically checked before collection or dispatch. The service provides an additional inspection step focused on the condition of the display panel.

What Is Not Included?

The Dead Pixel Check Service is an inspection service and does not include monitor repair, replacement parts, calibration, colour profiling, performance testing, gaming testing or long-term monitoring of the display. The service is focused specifically on checking the monitor for visible pixel-related defects and inspecting its visible condition at the time of testing. It does not guarantee that a pixel fault or another display issue cannot develop after the inspection due to future hardware failure, accidental damage, transport damage or other circumstances occurring after the monitor has been checked. Any warranty, replacement or return rights are subject to the applicable product warranty, retailer policies and relevant consumer rights.

Checking Your Monitor Before Collection or Delivery

Adding the Dead Pixel Check Service to your monitor order allows CompHub to inspect the selected display before it is handed over or prepared for delivery. After the visual and pixel inspection has been completed, the monitor is prepared for the chosen collection or delivery method. If you are purchasing multiple displays, each monitor can be checked individually by adding the service to the relevant product. This provides an additional quality-control step for customers who want their monitor screen inspected before receiving it. The service is particularly useful for customers who prefer to have the display tested using dedicated methods rather than carrying out the initial pixel inspection themselves after delivery.

Why Choose CompHub for a Monitor Check?

A monitor is one of the most important parts of a PC setup, and the quality of the display can have a significant impact on everyday work, gaming and entertainment. Our Dead Pixel Check Service provides an additional inspection before you receive your monitor, using both visual checks and dedicated screen testing methods to look for visible pixel defects. The service is performed on the specific monitor included in your order and gives you the option of having the display inspected before collection or dispatch. By adding this service, you receive an extra level of checking focused specifically on the condition of the screen and the detection of visible dead, hot or stuck pixels at the time of inspection.
