humm... can you explain further your uneven whites? would you say it's a screen gradient? how is it uneven? is it more warm (yellow) in the middle, cooler (blue) on the sides?

personally, i found that when i switched my screens profile to the Adobe (1998) profile (sys prefs > displays > color) that my screen gradient became less noticeable, albeit colder than the warm default iMac profile. perhaps your whites will become more uniform by doing so? i also upped the screen contrast just a touch (sys prefs > universal access > seeing > enhance contrast) as well.

I´d say it´s a little uneven (a bit brighter on the left side), minimal darker patches in most of the corners. And if you look at the picture I posted above there is a slight bluish color stretching from both sides. But all this considered it is minimal, and I think Apple did something to fix the issues. Especially since there is no backlight bleed that´s what I think. I can live with this.

Great, I´ll try the trick with the contrast! :)

my iMac has been perfect since day. because it has ran so well, I bought a MacBook a couple weeks ago. I am totally sold on Apple. :D

I agree.....as i said in another thread i'm sure apple has changed the way it mounts these screens as mine and my mates VM-Czech Republic models have zero bleed. ALL the other units I had have had pretty shocking bleed and this new one has NONE! This forum was a particular pain to look at with the previous units as it clearly displayed the gradient.......I cant notice it any more on my unit or my mates so even if there is something there its no longer noticeable to my eyes. I think that we may be safe to say that units week 20 and beyond from the VM plant are far less likely to have major screen issues. I for one am now very happy with my machine :D

I actually have about 90/100 pixels (yes i did count them..) which are orange whenever the screen is showing black. They are in a clump in the centre of the screen and are seriously annoying. It's just such a big computer to take back....

if you have apple care you can order an onsite technician (if you live within 50 miles / 80 kilometers of a certified apple tech)... they can come, evaluate your screen, if they can't fix it at your place (which they probably will not be able to), than they will take it with them, fix it, and return it back to you.

although if you can't be without a computer for any period of time and therefore want it replaced immediately you'll have to take it back to the store, which really sucks (i have experience) as they're heavy and not fun to carry around for any period of time.

i suggest you have it repaired or exchanged... your iMac costs too much money to have such an awful screen issue like that.

I had way more then 100 stuck pixels and sent that puppy packing back to Apple the next day. The replacement they sent is perfect.

yes:

I've seen a ton of Alu 20-24" iMacs and couldn't notice a color gradient unless it was very severe. For me, it's rare. Maybe because I'm not into photography or anything...but i have an eye for stuck/dead pixels.
 
yes

the first one has a stuck pixel
the second one had a left-right brightness difference
the third one had bleeding in the edges

I'm looking forward to the fourth ;)
 
week 20 no screen issues but one stuck pixel somewhere on the bottom right. its hiding from shame, keeping my new 24" from being perfect.
 
Yes. Stuck pixel and I *think* I have some gradient issues. Don't really care though.

You should try the pixel repair method here. Apply this flashing window over the pixel and slightly tap the screen with a cloth (be careful..). I got rid of a stuck pixel on my new iMac using this method :)

I´m not saying it´s definetly going to work, but keep at it for something like 2 minutes with the tapping, and then let the flashing window (you can minimize it just over the stuck pixel if you are epileptic...) stay for a bit longer. I might just do the trick.

I'm not sure tapping will help as there is a sheet of glass over the screen assembly and about a half inch gap. You could massage the top membrane of the panel IF you were brave enough to remove the top glass with a couple of suction cups as the glass screen is held in place by several magnets. If the machine is within the 14 day return period i'd personally take it back for replacement.

Worked for me at least, but you´re right that there is a gap. Tapping is probably off then, but try the pixel-repair window over the stuck pixel, it could help
 
i think what i have is a dead pixel, now that i see that program not working. its been 20 minutes and its still stuck...but on white it looks a little purplish. how do i know if its totally dead?

You didn´t do the tapping... :D

From WP:

Hot pixel
A permanently lit (white) pixel is called a hot pixel. Hot pixels are usually best seen against a dark background. In digital photography a dark frame is sometimes used to allow correction for hot pixels.

Dead pixel
A dead pixel is a defective pixel that remains unlit.[3] Dead pixels are usually best seen against a white background.

Stuck pixel
A stuck pixel will usually be most visible against a black background, where it will appear red, green, blue, cyan, magenta, or yellow, although stuck red, green, or blue pixels are most common. Each pixel on an LC monitor is composed of three subpixels, one red, one green, and one blue, which produce the visible color of the pixel by their relative brightness. A stuck pixel results from a manufacturing defect, which leaves one or more of these sub-pixels permanently turned on or off.

Stuck pixels are not guaranteed to be correctable, and can remain faulty for the life of the monitor. A stuck pixel might be fixed with JScreenFix, a Java-based application that flashes numerous colors with a very rapid intensity.
 
condesation in screen

I have taken delivery of a shiny new 24" Imac 3.06, 4GB and 1TB Hdd. Great machine except............. in the lower right hand side corner of the screen i can see, especially if black is showing in the area a fair bit of condensation beneath the glass. It is winter now in Aust and my room is cool, around 10-15oC (i like the cold) i can see it is condensation because if i put my heater on and raise the room the temperature the condensation disappears.

Do anyone else get this??? is it something that can be fixed?? should i send it back to apple to fix??

AH

Yes a few others have reported it and I have seen a couple of pictures here on the subject. If your Mac is a keeper except for the condensation take a look at YouTube for any one of the many videos that show how to remove the front clear cover to clean it on the inside. It is held on with magnets. The video below demonstrates how to do it. Its funny as well.

it's quite insane. with all the treads online concerning screen gradients, uneven backlighting, screen bleed-outs, and condensation problems, i'm thinking that next year's Nehalem iMac will also be delayed by months so that apple can pawn off yet another massive amount of refurbs before releasing new machines...

is it actually cheaper for apple to do that instead of fixing the problems? i have to wonder wether this is good business sense or not.

Customers don't care about how Apple will waste money because of all the returns...if Mr. X pays lots of money for an iMac, he expects it to be (near) perfect. If he's bothered by an issue, he should not decide to keep it just to save Apple a few bucks!

If you believe the problems are hugely widespread and very common, and the result of some inherent design defect, then no. It would be cheaper for Apple to fix the design problem. If you believe that the issues are less common, the result of normal defects from the manufacturing process, and far, far overblown in these forums, then, yes, it is actually cheaper for them to do that.
