Can I just check something?

Are the gradient and bleed issues there at the outset? Or do they ever develop/worsen over time?

I might be prepared to take a chance on ordering if I can exchange it immediately, but if this is something that could happen later on I'd be less keen due to the major inconvenience of having to send the whole thing away for repair or replacement.

You can see it out the box.....the gradient is clearly visable on the initial grey apple start screen....the bleed on black/dark colour screens.
 
You must like to torture yourself. I would have given up long before 16.

Please put yourself out of your misery and just take the glass off.

Take the glass off? I don't understand how that would help as the screen behind still has a glossy front membrane.
 
Backlight bleeding is just something people have to live with when it comes to current LCD technology. It happens on almost every LCD out there, only rarely will people get a perfectly even backlight. Severe blacklight bleed is something that should be worried about but a little bleed isnt worth getting mad about, its just the luck of the draw. It doesnt affect your work anymore than a little glare would, and its only noticeable when watching movies.

The 20" screen is true garbage and it definitely affects your work since it is impossible to get an even picture with correct contrast and color thanks to it being TN, thats something to get pissed about. But if people are expecting a perfect backlight from the 24" or any LCD then they are expecting too much, a little bleed isnt going to hurt anything.

I would consider this acceptable bleed: http://img142.imageshack.us/img142/9182/img1033qo8.jpg

this as severe: http://img218.imageshack.us/img218/5065/img2008hw4.jpg

this as good but not great: http://img85.imageshack.us/img85/7636/imgp1308ea8.jpg

I agree and would be happy with image 1 or image 3's bleed. I have had a variety of LCD panels on a variety of products 19" 42" 24" 20" etc and ipod touch's etc and can honestly say I have NEVER seen bleed anywhere near as bad as on the 24" imac's......I don't EVER expect to see a perfect 24" imac screen.....i'm looking for one that is OK-ish and the ones i have seen and taken pictures of are clearly NOT acceptable.
 
So you can say that "all iMacs have the gradient" and "all iMacs have the bleed". But I ask you, if the performance is this good to the naked eye, and you have to test it with a light meter to know, does it matter? I ask you, have you discovered a fundamental flaw with iMacs, or with LCD's in general?


...Either way, I think you can safely conclude that an iMac is not for your level of quality distinction. ;)

it's highly HIGHLY ghetto of Apple to have screen discoloration... cold/warm (blue yellow) gradients are very poor quality... this goes far beyond sub-par quality... this type of color cast on screens can be expected after what, maybe 5 or 6 years? but brand new?! no no... this is heartbreaking!

I don't think it's gray screens that need examining. I think examining some people's gray matter would be more insightful.

I'm curious if gray matter controls whining function.

honestly guys, this is not being "fussy"... if your whites are blue and yellow that's very bad... if you can't understand the gravity of this error then it's not only gradient screen issues that you're not seeing.

That's waaaay better than any I have seen......that one for me would be a keeper! Its not great thats for sure but i've not seen one that good. The colour cast from left too right is just as much of an issue and is very clearly bisable on solid colour screens. I really dont understand how and why apple is sending this stuff out. I'm sure they must be well awair of the problem and just accept that some people will return units and others (vast majority) will just put up with it.
 
dude i can see the gradient on your screen from here

thats really bad if your working on photos or any type of gradient or lighter shade graphics work

the hp 24 lcd i use at work is sollid all the way through and its a pretty cheap lcd.. so im speanding more money for less quality.. great :rolleyes:

What gradient do you see? I would be curious if your sight matches the measurements - your eyes can play tricks on you.

That "white" is actually grey - following the photo requirements by the detractors on this forum.
 
15 iMacs returned? I forget what the definition of insane was? Oh yeah doing the same thing and expecting a different result. :D

Seems to me you need to step up to Apple's professional line of products for your needs.

So I need to spend £2,300 on a cinema display and MacPro for no bleed? Helpfull and informative.....many thanks for your input :rolleyes:

No. Just buy a higher class of DVD player and watch your movies on a TV instead of expecting a computer monitor to do the same job.
Next, you'll be complaining the iMac's inbuilt speakers aren't as good as the ones you heard in the cinema – and telling us they should be in a machine costing $2,000.

The speakers are fine....this thread is about screen defects.....the imac 24" has a gradient left to right and backlight bleed.....try to stay on topic and stop trying to score points xxx
 
i just ordered Apple Care JUST so i could have onsite service on my display... i even checked online and asked apple on the phone if my desktop computer could get onsite service because of my iMac's gradient... i don't exactly live close to an apple store, nor do i care to pack and carry this heavy 24" iMac all the way across town...

"sure no problem, just give me your credit card number for Apple Care and then i'll transfer you to an onsite technician"...

...

"hi, i'm an onsite technician, and i can't do an onsite evaluation of your screen because i don't have the equipment to do so, you'll have to take it back to the apple store... bye!"...

APPLE SUCKS!!!!!!!!
 
16th iMac eh? Craziness.

The one and only 24" Alum iMac I had was tolerable, but not the greatest. I had the backlight bleed [of course], but only coming from the upper corners. I tolerated it for a bit, but eventually I couldn't take it anymore, and now have the 15" MBP.

Sadly, I do miss the iMac though...:(

Seems like a slight backlight bleed is tolerable only if it's on the middle top (like Darkroom's) or the middle bottom (like mine and czacorski's; visible only when watching movies as the dock normally hides it) rather than the corners.

All the different backlight bleed might very well be the result of the Alu case design (which would be patch-dependent depending on where it's manufactured) rather than the H-IPS panel itself.
 
Guess I got lucky. The new 24" 3ghz I bought has no perceptible screen bleed. I don't have a light meter but with a solid black background all the lighting appears to be even.

what about gradients? for example if you open safari or iTunes, can you see a slight shift in the color of the textured (metallic) window along the top? does it seem to be warmer (yellow) around the middle?

i'll be very jealous, yet hopeful, if you really don't have any issues at all with your screen.

Hmm, according to 'conventional wisdom' (a.k.a. Wikipedia.org) those
vaunted "H-IPS" panels are supposed to have "much less backlight bleed."

http://en.wikipedia.org/wiki/Thin_film_transistor_liquid_crystal_display#IPS

...waassup wi dat?

LK

i'm thinking the wikipedia article is talking more about a very slight bleed around the edges (of green only?)... anyway, i think what apple is selling is a flaw in the casing which is causing the screen to bleed out... to death... blood bath...

i'm not a fan at all about my $2000+ imac having any type of bleed, but i could tolerate it easily... however, it's the AWFUL cold/warm color gradient that is making me crazy... i just can't stand it... it's noticeable constantly...

Whats embarrassing about that? Thats above par backlight bleed. If you want better then shop for $1000+ LCD's or be prepared to ship back about 20 regular S-IPS monitors until you finally get a perfect backlight. You may expect better, but its scientifically not feasible and something you have to deal with.

Id like to see what it looks like with the lights on and at a normal viewing brightness, I bet its pretty much impossible to tell except for the bright spot at the top when watching widescreen movies.

I wish you hadn't mentioned the yellow discoloration! The new iMac I just set up has tolerable backlight bleed and a mild gradient, but now that I see the cool->warm->cool discoloration, I can't stand it. It's particularly bad on the MacRumors forums, where the grey background behind the text makes it pretty hard to ignore! :(:mad:
