Backlight bleeding?

[MR.Raul]

Finally got an iMac that has almost no dog whistle, after 4 tries, but now it has backlight bleeding.
Mostly in the bottom right corner.
How normal is this phenomenon on the new iMac?

Is it actual bleed, where there's abnormal spots of backlight seeping through, or is what you're seeing described as a gradient of light emitting from one of the corners of the iMac? Is that gradient of light only visible when viewing a darker screen in a lowly-lit room? If so, that's seemingly normal of a lot of LCD panels, as they're backlit from the 4 corners of the panel.

 

[MR.Raul]

Yes, it's a gradient of light emitting from one of the corners, when there's a black background on the screen.

Just needed to know if it was common on these new LCD screens as well, and guess it is.
Not gonna get improved either when the screens just keep on getting thinner as well.

 

[TMRaven]

Yes. The best way of making lcd panels thinner is they backlight them from the edges or corners, and use special filters to disperse the light as evenly as possible. Sadly that leads to more bleeding than arranging them evenly behind the screen. (in this case, the latter method evenly distributes a grayish black behind the whole screen)

Hopefully oled becomes common enough for commercial use, so we all can be rid of the backlighting issues that arise with LCD panels.

Light bleeding is not normal and most iMacs don't suffer from it. If it bugs you, replace the computer and make sure that you are really getting a new, unopened box this time.

I can't, this is my forth and definitely the last one they'll send to me, they made an exception sending me a forth.
Of course the main problem on the 3 first ones were dog whistle and buzz, and now got one without it (almost) but Light Bleeding and a humming (as I posted here... https://forums.macrumors.com/threads/1032265/ ) noise instead.
Smaller issue was that the magic mouse was not working at all times when right clicking it, it's a mechanical issue.
They even said I won't be getting a compensation (if I decide to keep this one, or ells I can totally forget about it then) since they sent me the forth one as an exception.
I do not like that I as a customer should have to decide whether to keep this one with "minor" issues or not get one at all, I should't have to take that as I payed for a fully working machine without any issues, no matter how small they are.
I'm starting to dislike this product due to all the hassle I've had to go through (and not even done yet), even though without any issues, it's a nice computer.

I'd suggest email Steve Jobs directly (write a nice letter) and ask for help. Your post above is a good start. Tell him you are basically at the end of your rope in Sweden and so on. It sounds as an unlikely avenue, but some people reported that this actually worked very well.
You could also call/email Customer Service, first in Sweden, then in Europe, and finally the Global Headquarter in California (OK, I am not sure about the Europe, if they have one).
There is no such a thing as "this is your fourth and definitely the last one" expression in Apple language.

I'll give it a try, instead of buying a lottery ticket 😛
Have you got that in writing somewhere, the "There is no such a thing as "this is your fourth and definitely the last one" expression in Apple language."?

Good luck! let us know how it goes!
