I thought it would be great if some of the 24" owners with good screens could take the time and effort to post a pic.
I´ve seen a couple of good ones and it would be real encouraging to see that there are plenty more good ones out there.
I also think this could be useful to future buyers whom are wondering if there are any good screens at all and put an end to those who claim that there aren´t any.

Thanks!
 
mine is just fine. too many people bitch about tiny little things :rolleyes:

hard to get a good pic (the vertical line on the left is some sort of artifact) , but here you go:

I have one "white" (stuck?) pixel. can you spot it ?

Good idea! However, just any ol' photo won't do. To demonstrate brightness and color uniformity (or lack thereof), the best 'subjects' are clutter-free desktops with solid-color backgrounds:

- "Solid Aqua Blue" for evaluating brightness uniformity

- "Solid Gray (Medium or Light)" for evaluating color uniformity


Kinda like these -- but hopefully, without the uglies:

...and turn off the room lights to avoid reflection artifacts,

Good points. For example, in the pic that Nissan posted, the race track is darker on one side, where the cars have traveled more. Is that darkness just the track, or in part the brightness gradient? It is hard to tell. Trusting Nissan's post, it is probably just the track, but a better background image would make it more clear.
 
the pic I posted isn't perfectly accurate, but it's close -- the track is darker on the right.

as Washac correctly says, what matters is real life use, not artificial setups

the display isn't PERFECT, but it's damn good. I have no complaints. Want better ? Sack up for big bucks, but you'll probably never be happy.

Problem is, that photo conveys ZERO information on the display's quality. It might be absolutely 100% perfect, or in might have huge color and brightness gradients. There's no way to tell.

Brightnesss and color uniformity are measurable and photograph-able, while "damn good" is just one more anonymous net.opinion.

BTW, are the solid white 'n gray backgrounds on this web page an "artificial setup?"

OR, you could "sack up" $1200 or $1500 for a (brand new) 20" or 24" White C2D iMac.

Here are some photos of my white 20" upgrade from the two ALU uglies. Uniform color, very good off-axis performance, and brightness uniformity approximately TEN TIMES BETTER than either of the ALU disasters.

http://picasaweb.google.com/TheLooby/White20IMacScreenPhotos

The screen's brightness is so uniform that my camera's light meter can't detect ANY variation at all. So, all I can say is that any "gradients" are below the meter's limit of resolution -- with LESS THAN 20% difference between max and min. (The five 24" ALU iMac samples I've measured had left:right brightness differences ranging from 150% to 270%.)

...hmm? If "aluminum and glass" is the answer, WHAT was the question?

Just downloaded the Leopard guided tour from Apple, and couldn't help but notice the nice uniformity on the screen in the video. That from a pretty high off-axis angle, too.

I don't think so. I just watched it, and for instance, when they were demo'ing iChat, you could see the video window was live with the other person blinking and stuff. Its the same exact camera angle as the one I posted.

For example, in the shot below, he has just rotated from facing the iMac, to facing the camera. As he rotated, his little image in the corner of iChat rotated, and you can see his chat-mate blinking and moving. Watching this demo definitely proves to me that there is at least one perfectly functioning iMac screen somewhere at Apple.

Just some other photos I found around the web......I'm hard pressed to tell which of these has it and which do not, primarily because they are photos of actual use. Perhaps if people would put solid colors and take the photos straight on with low room lighting, we would have a better understanding, but most people just post pics in actual use (similar to how they use them, I suppose).

the computer is a fake, it was done in post.
The keyboard has no wire to the computer, and its not the bluetooth version cause its the full size.

I can see the cable from the keyboard to the computer! Look above the keyboard, near the foot of the iMac.

Did you watch the video? It's pretty clear it's real. The other pics I posted - are they faked too?

I've seen NO complaints -- anywhere -- about color uniformity or off-axis performance with the 24" iMacs. The 24" problem is a severe (2.5:1) left:right brightness gradient.

None of the photos posted here so far provides any useful information on that subject. You can't judge a display's quality if you don't know what the image SHOULD look like.

The 20" iMacs have severe top-to-bottom brightness and color non-uniformities. For example, the "ars technica" web page in your post #12 has a strong gradient in the vertical gray side bars. That might be an intentional "gradient fill," _OR_ it might be the 20" iMac's classic display FUBAR. We have no way of knowing for sure...

...but I'd be happy to place a small wager,

The last picture I posted has a gradient from left to right across the bottom of the .........hold......hold....wait for it........across the bottom of the iMac in the aluminum. What are you going to do?

If one side of the screen was 2.5x as bright as the the other, you would think it would show definitively in one of these pics.

Leon, in all honesty I see the gradient in your white iMac pics. I see brighter look on the left of the screen as opposed to the right in the grey and blue background pics. I really don't see any difference from your Alu iMac pics to your new white iMac pics.

Didya ever hear of MEASUREMENT ?

I invite you re-visit my picasaweb galleries and MEASURE the screen photos of all three iMacs.

http://picasaweb.google.com/TheLooby

Hint: If you actually own an Apple computer, you might try:

/Applications/Utilities/DigitalColor Meter.app

Then please come back and tell us all what you found.

...the physical universe doesn't give a rat's rump about "opinions,"

Leon - I am very interested to be the random sample for the 24" iMac - when mine comes in (scheduled for Th or Fri next week). In the mean time, I challenge you in a similar manner that you have challenged those here to post a pic of a working 24" iMac. I have found dozens on google images. Here is the thing, I don't see many images on google images of ones that definitively have the 24" brightness issues. Certainly of over a dozen I have posted, one would have this problem visible if every single 24" iMac had this defect. But here is the thing: none of them do. And furthermore, I did not see any in google images that definitively had it.

So here is my challenge: if this problem is so widespread, go on to google images, and post pics of even half as many that definitively have this problem as I have.

(I post this knowing full-well that I have jinxed myself and my 24" iMac will show up with the brightness issue AND the freezing problem. :(
 
I'm going to back up the others here by saying that the pics of your white iMac screen show traces of a gradient as well (lighter on the left)

Now, my 24" Alu iMac has a little screen issue itself, but not a gradient. When my screen is all black (and only noticable when black), I can see a lighter blob of about 3-4" wide and about an inch high (it's very very faded/blurry though, but it's there).. It doesn't annoy me at all though.. But if my iMac keeps getting the freezes after Leopard (or a fix to all OS'), I'm going to exchange it stating that it has uneven brightness, a dead pixel and freezing issues. (maybe even wait untill after a new hardware revision :p)
 
buying a new iMac?

hey,

i am a future switcher (am i in the right thread?), and i have been waiting for the leopard release to buy an Imac with the new OS pre-installed. however I was taken a little bit aback after reading all the posts concerning the freezing issue.

did this happen to the vast majority of people or just a few unlucky ones? shall i wait until this is finally fixed or shall i buy it right after october 26th with my fingers crossed hoping that if i ever encounter these sort of problems a future update shoudl fix it or in worst case scenario, i get my machine replaced for a new one of repared?

what do you think?

thanks in advance for your help!:eek:

I took delivery of my 24" aluminum iMac on 8/17 and have had not had any freezing issues whatsoever. I appled the 1.1 update when it came out.

Incidentally even though you didn't ask I don't have the mysterious "gradient" issue either. I "upgraded" from an early 2006 20" Core Duo iMac with a matte display which didn't have it either. Personally I like the glossy screen better than the matte too.

The only negative issue I've had with the machine is my down arrow key on the aluminum keyboard seems to have gone a bit soft and sometimes doesn't register a keystroke depending on how I hit it. I may be sending it in for a replacement. I love the aluminum keyboard otherwise.

It's a great machine and I can't recommend it highly enough.
 
I don't "think I see", I even tried that digital colormeter and it does show up that the left side is lighter than the right side (31-51-66 left, 27-46-59 right).
