sorry cant you just calibrate the colour in the display settings?

Somehow when this went mainstream, people lost track of what the problem actually was...

The issue is a color temperature GRADIENT, so that some parts of the screen are different from others. If the entire screen were a little more yellowish there would be no problem.
 
Apple or LG never improved the 'Yellow/Gradient' issues on the 24" imacs.
Sometimes these artefacts are just inherent to the screens in-question. Cheap TN S***T!

Whats with the brightness scale on the imacs too! Why doesn't the imac 27 dim all the way to black? That rang alarm bells for me and reminds me of the the panels used in the 24". (Same odyssey and looks like same issues!)

Looks like apple have attempted to sort quality issues,

"Gizmodo reports that it has received official word from Apple that the company has addressed issues with flickering and yellow tinting on its 27-inch iMac models.
We've addressed the issues that caused display flickering and yellow tint. Customers concerned that their iMac is affected should contact AppleCare."
 
Until they run out of screens and LG starts making better ones.

There is no point to bother with this any longer.

You will get a screen with some degree of yellow.

The data is just too overwhelming plus the fact that they are telling people to live with it or return it.

Plus apple states that the imac is not a Pro product and that the screen they are delivering is acceptable.

You must be imagining things because Apple has never stated that.

Many people, including me, have no yellow in their screens.
 
I have had 2 of the supposedly fixed screens

And 2 of the old style. They all had yellow screens.

Of you take a photo and crop all 4 corners next to each other you will see the colors are not consistent or even close.

Some have yellow worse than others but they all have it to one degrees.
 
The conclusion to this "saga"?

i also just had some service techs over. the diagnostics that they ran indicated something was wrong. dunno whats the failing code number though.
