Monitor - Pixel Issues - Just Checking I'm Right?

Sent them that exact document. My monitor's 2560 X 1440 (not 1600). So it has some 750,000 subpixels fewer - taking it under 12m.

They tried to quote this to me as whole pixels - seems they believe that 2560 x 1600 is over 12m (it's not even close).

It is close to 12 million... it's over 11 million.

2560 x 1440 = 3686400 = number of pixels on your screen.

x3 = 11059200 = number of sub-pixels on your screen.

The next lower figure in LG's table allows for seven dead sub-pixels without a defect being acknowledged.

Maybe you can convince them that all three of the sub-pixels in each of the defective pixels in your screen are dead. In which case you are talking about twelve dead sub-pixels.

Their table does not show a smooth progression, so it is likely that they would say that any screen having between 6912000 and 12288000 sub-pixels is allowed to have twelve dead sub-pixels, or four pixels in your case, before a defect is acknowledged.

Good luck.

It's certainly an incredibly vague document despite the title of policy. The above is the information I've relayed to them, no response as of yet.

The frustration is due to their staff not knowing the difference between sub-pixels and pixels and believing they are allowed 12 whole failed pixels on screen - which would be an outrageous figure. This is what I mean by 2560 x 1600 not being close to 12m. It's about 4m. The table illustrates the tolerance for subpixels, and they're quoting it back as whole pixels.

Confused? Don't worry, so are they, and they work for LG...

The document linked above states up to 12 dark sub-pixels for a 2560x1600 monitor. The problem seems to be that your google search suggests that a dark pixel is the result of 3 failed sub-pixels so you are jumping to the conclusion and assuming you have 12 failed sub-pixels. Whether it is 4 failed sub pixels or 12, either way it is within the level they state as acceptible

I don't agree with that as this page <never mind, not allowed to post links>, amongst other, states that black pixels are the result of three failed subpixels - I'm not sure reading various sources, learning how a pixel works, and using this information to support my claim, is jumping to conclusions.

12 wouldn't be within stated tolerances as it states "1 per one million pixels", so 11 should be the maximum allowed.

I don't know if it will work but if you 'google 'pixel massager' there is software out there that claims to fix pixel problems.
