Lite bluish tint to screen

Hi-

I am experiencing the exact same thing. I actually posted a question earlier but I described it as the screen being brighter when it first wakes from sleep and then dimming a little bit. Of course the bluish tint would explain that and is a better description of the problem after going back and looking at my computer again. Like yourself, the problem doesn't interfere with anything, but it certainly doesn't seem right. Have you called Apple about this yet or perhaps figured out what the problem is? I just got my iMac and would rather not have to send it in for repair already. But it is a nagging issue that I would like to resolve somehow.

When I first got my 27 inch, when viewing the screen from an angle, I noticed a bluish tinge. I took it to the Apple store and the genius said he couldn't see it. It really doesn't bother me so I let it go. But it's good to see that other people have noticed it.

I can't decide if I want to deal with dragging the machine to the Apple Store only for them to tell me they don't see the problem and/or that there isn't any fix for it. It's funny because I originally had the 27 inch iMac, but I had screen issues with that (screen flickering and screen blacking out for a second or two, which has been widely reported) and additionally for me it was just too big of a screen for my desk, causing me head and neck aches trying to sit in front of it comfortably. Maybe the bluish tint issue will be fixed through a future OS update, for I believe it's a software issue and not hardware.

It's up to you how you want to handle it. Personally, I notice it only when I view the monitor from an angle. I figured I'm just going to live with it because you really can't use the computer while viewing the monitor from an angle, unless you're a gymnastic or something like that.

A very reasonable approach; I suspect you enjoy using your computer.

I never understood how important work could be done while viewing grey bars across one's screen looking for minute colour variations. When my screen blanker was displaying my photos with the Ken Burns effect, I looked hard to see the colour variation in a given portion of the photo as the photo moved at various angles across the screen - couldn't swear I could see a problem on the monitor I'm using now. If I stare hard enough at alternating light and dark grey bars on the screen, I might even see the Shroud of Turin on the screen eventually. On this monitor or any monitor.

Okay, I'll be serious for a moment...

I am not denying there are some with very evident and serious colour problems of course. But for the vast majority, considering the price of the entire 27" iMac is less than half the price of a professional-grade colour Eizo monitor... e.g. $4,400 for a 30" monitor with 97% Adobe RGB colour-space and only 290 cd/m², I don't think every monitor will be perfectly uniform. Eizo verifies uniformity over 25 points on the display. I don't know what Apple does of course.

I have noticed several people saying they can tolerate a little colour variation, but the flickering / tearing / blackouts are not acceptable. I agree with that and also expect those problems will be resolved in our first year of ownership so everyone will be covered by their warranty.

Pardon my typo; the EizoCG301W is 260 cd/m².

Just a quick update after talking to an Apple technician who told me they are working on another firmware fix to address the inconsistent colour issue that should be ready for distribution in about two weeks.

If it's a super faint blue tint that you see in the whites, it could be the natural effect you're noticing of the LED backlighting which does have a bit of a faint blue colour cast to it. It's hard to say if that's your issue without seeing it up close and personal. I calibrated my screen with a Spyder2 and thought it was ok and then found out the Spyder2 was not recommended by DataColor for Wide Gamut or LED backlighting of which the new iMac's have both.

Replaced it with a Spyder3 and ColorEyes software and it most definitely did a better profile and pulled the light blue cast right out of the screen. Very pleased now. Worth a shot if that's the issue with yours. Cheers!

I'm not a professional photographer or videographer so to me, color calibration, etc. is not that important. As long as my daughter (in pictures) doesn't look purple like Barney or sand on the beach (I live in Hawaii) look like puke green. I'm just responding to the original poster who seems to be bothered by the bluish tint to the screen. If it bothers him, he should have it checked out. To me it doesn't bother me enough to haul the computer all the way back to the store just because I can see a bluish tint while looking at the monitor from an angle.

I am experiencing the same thing. After the imac has been sleeping for 1 hour or more (that is a guess... I just know that 30 mins of sleep is not long enough) upon waking it the screen will be very bright and crisp, but within 2-3 seconds, perhaps a bit longer, the screen takes on a blue/gray cast that washes out the bright whites. If I wasn't able to physically watch the color change upon waking the computer I would probably had not noticed this. However now I am reminded of the problem every time I wake from an extended sleep cycle. Anyone know of a fix for this? All help is appreciated. Thanks.

I also own a brand-new iMac with a 21.5" display and experiencing this blue tint also. If my Mac wakes up from sleep-mode everything displays "normal" for a few seconds and than there is a light blue layer covering the whole screen. Not really sure if this was really from the first start on.

My 27" imac also experiences this. It is most noticable, because upon waking the display from sleep it is "normal" and then there is a quiet, but audible, "click" and the blue tint turns on.

I had suspected that this was a 'firmware fix' to try to eliminate or lessen the yellow hue problem (my computer has a slight tinge) but I am not sure.

I don't believe this always occurred (started using this mac in January), but it now occurs with regular frequency upon waking.

I am experiencing blue tint and have not installed any firmware updates for the 27" imac. So I dont think that explains it.

I I've noticed this as well, and only occurs for me after the computer has been asleep for an extended period (an hour...?). When it turns on, everything is perfectly white, but then gets a blue tint about 2 seconds after being on.

White balance on my photos is really important to me, and seems to throw me off because when i look at my photos on others' computers, they are always a little too warm.
