I have a dead pixel on my monitor; can it be replaced under warranty?

If your monitor only has one dead pixel it's unlikely to be classed as faulty, however if your monitor has multiple dead pixels (usually 7 or more on a resolution of 1024x728), then we may be able to submit a warranty claim.

Contact our technical support department on 01274 471204.

Please see the pixel policy supported by the majority of monitor manufacturers below for reference:

TFT & LCD Panel “Dead Pixel” Policy

Please read before purchasing a flat screen product

Introduction
LCD displays are made up of a set number of pixels and each pixel is made from 3 subpixels; one Red, one Blue and one Green. Every sub-pixel is addressed by its own transistor and so the manufacture of a glass substrate is 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.

To regulate the acceptability of defects and to protect the end user, ISO have created a standard for manufacturers to follow. ISO 13406-2 recommends how many defects are acceptable in a display before it should be replaced, within the terms & conditions of warranty. All reputable manufacturers conform to and support the ISO 13406-2 standard.

Pixel defects       
The table below shows the allowable number of malfunctioning pixels that are acceptable, depending on the native resolution of the LCD and allowing for 2 malfunctioning pixels per million pixels.

The table below shows the allowable number of malfunctioning sub-pixels that are acceptable, depending on the native resolution of the LCD and allowing for 5 malfunctioning sub-pixels per million pixels.

The table below shows the allowable number of malfunctioning sub-pixels that are acceptable within a 5 x 5 block of pixels, depending on the native resolution and allowing for 2 malfunctioning sub-pixels within a 5 x 5 block, per million pixels.

The above is relevant to Class II LCD panels.
