Guys, he has like 10 dead pixels...is everybody just ignoring that!!!
Or am I in with the lunatics who think that this is a defect 😕
Well, here is other manufacturer standards:
Laptop Brand / OEM (Bright Dots,Dark Dots,Total Dots)
Dell (7,7,7)
IBM (5-11,5-16,9-16)
HP/Compaq (7,7,9)
LG.Philips (6,6,10)
Sharp (7,7,N/A)
ScreenTek (3,3,3)
I've talked with Apple and they state 4-5 dead/stuck pixels is the minimum with some exceptions.
According to ISO 13406-2 (the standard which most manufacturers refer to):
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. 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 defaults 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 defaults (for Class II LCD panels)
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.
(Native Resolution--No. of Pixels--No. of Million Pixels--Allowable Defects)
1024 x 768--786,432--0.79--4
1280 x 1024--1,310,720--1.31--7
1600 x 1200--1,920,000--1.92--10
2048 x 1536--3,145,728--3.15--16
Most, if not all, LCD monitor for commercial purpose are fit in Class II. Class I is for military, hospital or other critical applications.
So, for the MacBook that is "7" and for the MBP that is "8-9". So this is the ISO, so this is the bare allowable. I would expect Apple to exceed these standards.
Grumman stated he had 1 dead and 5-8 stuck. That means he has 6-9 bad pixels. I think he has every right to return it and I bet Apple would agree with me.
