What is LG electronics pixel policy?

Archived from groups: comp.sys.laptops (More info?)

A pixel is made up of 3 "sub-pixels", one each, red, blue and green.

There is no "white". If you have a blue dot on a white background, that
actually suggests that the red and green sub-pixels of that pixel are
both dead, leaving only blue.

Beyond that, it's hard to diagnose without seeing it, sounds like you
have a bad pixel. There is no manufacturer that considers a single bad
pixel to be a defect.

It looks like 2 adjacent vertical red pixels are dead, about 32mm from
the left edge of the screen. I don't know what LG's policy is here in
the UK. But I came across an American site that mentioned LG is 8
dead pixels.

It's not a major problem. I've positioned the windows xp taskbar on
the left side on my screen and resized it to cover the dead pixels.
The monitor is 19 inches, so I have plenty of free space for big
taskbars.
