There are 3.9 million sub-pixels (red, green and blue) on a standard 1280x1024 resolution LCD monitor, each of these is a microscopic transistor. While the defective rate of pixels on LCD panels and plasma displays is very small, due to the large number of sub-pixels, manufacturers cannot guarantee 100% error-free panels at an affordable price. To make things more difficult, it is not possible to test any pixels before full assembly of the panel, and fixing any pixels is not possible after assembly. Malfunctioning pixels can be disturbing If a pixel or sub-pixel is dead, it appears as a black or colored dot on an all-white background. In addition, some pixels can stay in a permanently “turned-on” state (this is more common than dead pixels), resulting in a white, red, green, or blue pixel on an all-black background.

If you find any defective pixels on your new LCD monitor or plasma display during the warranty period, it may qualify for a replacement. How does it work?

O meu tá zerado (é um Philips), e parece que atualmente já tá muito raro pegar um monitor LCD com dead pixel, se ele for de boa procedência. Já essas marcas desconhecidas que pipocam no mercado sem nenhum controle de qualidade, sei não :confused:
Eu por exemplo nunca engoli essa história de ser “aceitável” que um LCD tenha lá sua meia dúzia de dead pixels, antes que possa ser retornado à fábrica… Pra mim é pura negligência no controle de qualidade.

A pouco tempo quando estava cogitando comprar um LCD, descobri
que a Sansung troca se tiver 1 pixel queimado e a LG 3 se estiverem
