Recommended iMac display calibration settings

Trying to calibrate my 2011 27" iMac with a Datacolor Spyder4 Pro.
Their calibration tool recommends a brightness of 180, but I have seen other articles from other sources recommending something closer to 120.
At 180, the display seem extremely bright - and when some of my photos are viewed on other / non-calibrated monitors, they are darker that what I would expect.
Also, I know that the iMac has an LED display, but that does not seem to be an option during the setup - is LCD the best choice?
Any recommendtions on settng for proper calibration of this display would be appreciated...
Thanks

It is an LCD display, the back light is LED. Use LCD

MBA display calibration settings

Hi,
Got a 11in MBA 2011 recently, very happy with it. Until now, however, I was unable to calibrate the screen. But yesterday X-Rite released the calibration software for my eye-one display 2 that is compatible with OSX Lion.
I'm unsure what settings to use with the MBA display? White point D65 (or higher?), Luminance 100 or 120?, gamma 2.2.
I believe my display is the one made by LG.
Thanks a lot!
Hans

Help needed with ColorEyes Pro and 27" iMac display calibration

I am trying out a demo of ColorEyes Pro and using it with my Spyder2 puck, but there are a few things I just don't know and/or understand as they don't even ask them when using the Spyder software.
White Point Target - no idea what this should be
Gamma Target - 2.2 I am guessing, but not sure
Black Point Target - no idea on this either
Also, what should by "brightness" be set too? Or is that a personal thing?
Thanks in advance...

Hi Rich, I think it should work that way, but not the other way around...
Here's how it's supposed to work...

Calibrating iMac Display Have Questions?

I'm using Spyder4Pro Monitor Calibration software and hardware. I have a 2008 24" iMac 2.8 GHz Intel Core 2 Duo.
The wizard is asking whether my computer has: 1) Gamut - a) Normal Gamut or b) Wide Gamut and 2) Backlight - a) Fluorescent(CCFL) or b) White LED or c) RGB LED.
Does anyone know these 2 answers? Also, my calibration is turning the screen too blue and I'm trying to determine why?
Thanks

Actually baltwo, I called Apple early in the morning because I had not gotten any responses from the forum. I did check 1) ColorSync Utility, select Devices->Display, and peruse the display profile settings, and the information was not there but I did not try your 1st suggestion 2) Run through Displays->Color->Calibrate (using the advanced mode). IIRC, that should allow you to determine those items.
Since Apple gave me the answers I just went with what they said. Apple did say it is likely I got a defective product so I am returning it.
Again, thanks for your reply.

Colour Calibration / White Point setting - Is Imac Display really professional quality

I am trying to calibrate my imac 27" using i1 Display2 calibration software. I am trying to set a traget of 6500 using the software but it advises the current is only 5600 and suggests moving the RGB sliders to get this current white point up to my 6500 target. Unfortunatly i have no idea where i find these sliders on my imac. Can anyone advise how i change my current white point to get to the 6500 target?
Also, on the brightness issue, does shades work to reduce my brightness or will it simply interfere with my colour calibration?
Finally, i was going to use my iMac for professional photography. (Mainly on line but some print work required). Honestly, is the iMac display up to the job or should i consider changing
Thanks

Corbybhy, the glossy screen is the biggest and silliest myth out there. Really.
I have been a professional art director & designer for over 26 years, and by the way, for many years my high end professional CRTS were made of glass (and glossy). Another myth is that the screens cannot be calibrated, and are too bright. Hogwash. I use Spyder3Pro and have had few problems, guessing your device will be the same. Actually, the monitors seem to stay consistant for a heck of a lot longer than the old high end CRTs did. In the old days, most professionals calibrated to 5000k, but these days 6500k is the standard.
The amount of MISINFORMATION that is being spewed always amazes me. If you can keep your lighting consistant and somewhat dim, your life will be easier. Reflections are simply not a major issue, and are also overblown as a issue (by the way, my iMac sits next to a window, I just use shades to dim the ambient light).
I work mostly in print, and produce mostly publications, advertising & marketing materials. I have ZERO issues with my screen matching my proofs. ZERO. I do a huge amount of imaging, retouching & post-processing... all from my 27" iMac.

Calibration: iMac displays grey as white

I bought a hardware calibration tool (Spyder 3 Express) to adjust my Mac's monitor (iMac 27" 2011).
Everything looks fine, but yesterday I saw a photo of me on another monitor and noticed a greyish background. My iMac displays pure white and I didn't see the grey. It looks pretty unprofessional :-(
With Photohop's eyedropper tool I can see it is not white but about 248 250 251
So, how can adjust it? Is the iMac able to display this fine grade of grey? I hope so, the other monitor was a LG for 150$

The slider was on the left.
Here is a screenshot of a photo. The left photo is how it looks on my Mac. The other two are how the photo looks on other monitors.

Has anyone calibrated an iMac display?

I just purchased my first iMac. My previous displays were CRT monitors and I was able to calibrate them with the Eye One Display 2 from Mamiya/Gretag Macbeth. There are no adjustment buttons to fine tune the color temperature on the iMac. Has anyone had any success running calibration software of their iMac display? As a photographer, I need to know that what I see on my monitor is accurate color so my prints will match what I see when they come back from my photo lab

Hi,
the new iMac has a glass surface which makes it hard to calibrate with mostly every older calibration tools.
I now use the new Datacolor Spyder3Pro which works perfectly on my iMac. It has been specially designed for glossy display, LED backlight and wide gamut screens...
It's also doing a fine job on my MacBook Pro with LED backlight, where my Eye1 failed before.
Just my 2 cents...

LP2475 - best colour calibration settings for stock photography

Hi - I have just purchased the LP2475 and am new at colour calibration. The general colour seems very over saturated.
I am mainly using the monitor it to do 2 main things :
1) using lightroom / pshop and adjusting photos that will be available online for stock photography purchasing.
2) using lightroom /pshop and adjusting panos to print via 2 out-of-house print companies.
I understand that I have to buy a colour calibration device and I will make up custom printer profiles for the 2 different companies where I get my photos printed (one is a canvas & one is a photo printing company).
However, the issue lies in what general calibration settings I should have in lightroom / pshop for my stock photos - because once sold, they will be printed on all various types of printers, and viewed through various types of monitors - most not calibrated. So what are good general settings. It seems very over saturated with colour, and I cannot actually seem to adjust the saturation in the button menu on the monitor as this setting is greyed out.
Thanks

I recently bought a Spyder2Pro, which was
recommended
by Scott Kelby, Editor of Photoshop User Magazine,
and am very happy with it. The main difference
between Spyder2Pro and Spyder2 are multiple
monitor
support and more choices for monitor gamma and
tempereature settings. Since I use multiple
monitors, I went for Spyder2Pro, although it was a
bit more pricy (got it for $189 at JR.com). All
my
monitors were calibrated very quickly and I was
amazed how much difference the tool made. If you
have one monitor to calibrate, I think Spyder2
would
be fine (it was $89 at JR.com a few days ago).
One hint with the multiple monitor thing is that on
the Mac, all of these tools just end up generating an
ICC profile that gets assigned to your monitor.
What that means is that they all actually support
multiple monitors, just not all automatically... for
the ones that do not know how to select displays, you
can just move the menu bar to whatever screen you
wish to profile and the software should create a
profile for that screen.
I use the EyeOne and like it a lot. But any hardware
calibrator is better than none.
As a side note, I think using a color temperature of
65k for the monitor and a gamma of 2.2 is really a
good setting to use with any calibrator.
Svendo,
I fully support the comments in this post but still prefer the GM Eye 1. Dont try to do the job with your eye. 99 times out of 100 you will be way off the mark.

How best to calibrate monitor using Display Calibrator Assistant?

I have had my 20" iMac since January 2007, but have not yet calibrated the monitor which I understand is a good thing to do periodically. I would like to do this using the Display Calibrator Assistant available via Mac System Preferences.
My Internet research on this subject has uncovered some controversy on how to perform the calibration. For example, a preponderance of opinion seems to be that the Gamma setting should be 2.2 instead of the 1.8 recommended by Apple for Mac OS computers. There are also differing opinions on whether to use the Expert Mode when calibrating.
I would appreciate an authoritative response on how best to perform the monitor calibration. For your information my primary interest regarding calibration is making sure that colors are correct when I am viewing and editing photographic digital images that I store in iPhoto.

Hey, Pete!
With my Nikon I can set the color space to either Adobe RGB or sRGB. Ken Rockwell (kenrockwell.com) is very knowledgeable in this area, and in his User's Guide for the D200, strongly advises the default sRGB setting unless the user really knows what he is doing with Adobe RGB and does his own printing. I don't agree with all of Mr. Rockwell's pronouncements, but on this issue I opted to follow his advice.
I don't find noise to be a significant issue with the D200 from ISO 100 through 1600. Noise gets pretty bad at ISO 3200, but the Noise Ninja program is very helpful in reducing noise to acceptable levels. Noise is worse in underexposed areas, but on balance I still prefer underexposure--within reason--to overexposure.
I started out my use of the D200 shooting everything in RAW + JPEG (Large Normal Optimal Quality), but in most instances I didn't feel that RAW gave me noticeably better results than JPEG. Also, RAW images chew up a lot of hard drive space. I now shoot most stuff JPEG, but employ RAW in situations that might present a problem, like when shooting sporting events in school gymnasiums which typically have abominable lighting conditions. With RAW images white balance is easier to adjust than with JPEGs. On the Internet I have read a number of impassioned arguments in favor of RAW over JPEG, but I still consider RAW to be a digital image format and not a religion! Therefore, I don't fear consignment to hades as a penalty for shooting JPEGs!

Display Geometry Settings GONE

I have a 21" Apple Studio Display (VGA) and am using it as a second monitor, but now with 10.6 the geometry settings are gone. Snow Leopard also tweaked/modified my displays so I do need to adjust the image or dramatically lower the resolution to get the image correct - it's distorted to an unusable state.
Anyone know of a third party tool to adjust the geometry of Apple's CRT displays - I have a second 17" in the basement that I'm sure will run into the same issue shortly - as I'm assuming Apple won't be of any help.

My iMac has had a similar problem since the display was repaired while the machine was still under warranty (the problem back then was rolling flickering lines). The display gradually becomes shorter and wider; the only remedy is to turn the machine off and let it cool down for a couple of hours. I have to keep my display geometry settings at a "happy medium" so the Dock arrows on the left side are not totally cut off and so I can read DragThing's tabs at the bottom of the screen.

New iMac display on/off

Does the new iMac have an on/off button for the display that is separate from the on/off power button for the iMac itself?
It would be nice to have the ability to turn off the display, when not in use, without having to powering down the iMac.

Sleeping the entire machine is one thing. Sleeping the display is a separate issue.
It seems there's currently no way to PERMANENTLY turn off the display backlight on an iMac. Setting a display time-out in the energy-saver settings or Ctrl-Shift-eject is supposed turn off the backlight, but if you have applications running on the machine, the display will turn itself back on again after a few seconds. (Try sleeping in a room with an iMac display on. Even displaying a black jpeg with the brightness turned down, you'll need to physically cover the screen!) The backlight will normally power down properly when there's nothing running on the machine, but if the machine weren't doing anything, I'd just sleep the whole machine, not just the display!! I want to sleep just the display/backlight when there are time-consuming applications running in the background, i.e., if the machine is encoding, running backups, syncing with cloud/server drives, etc.
This thread shows many other people having the same problem:
http://mac.elated.com/2007/02/02/why-cant-you-turn-off-the-screen/
It seems this has been a problem for well over a year and I've not even seen Apple acknowledge the issue. IMHO, not being able to leave applications running with the backlight turned off is a critical design flaw. If I'd known this in advance, I'd have bought a Windows PC Now regretting my iMac purchase...

IMac Display stretched and out of focus

My iMac display is not right. It is slightly enlarged and out of focus. I have already tried the display settings and holding the control key and scrolling down. I also tried restarting. Nothing is working. Last night I tried configuring my router for wireless. I supposedly made it secure with a password, which I had to use to connect to my network. The screen thing happened after that. This morning I checked the connection again and the little lock icon was no longer there. Could the two be related? Please help! I am obviously not very apt with computers, but I'm trying.

This resolved my issues:
Preferrences > Accessibility > Zoom
then, uncheck Zoom and uncheck Zoom follows keboard focus.
Wait a few minutes. You can rechec them again but it won't go back to the stretched and out of focus look. I don't know why.

Recommend a monitor calibration tool please

I use a MacBook Pro. 15" And Aperture. What units are folks using to calibrate their monitors?
Spyder3?
X-Rite EODIS2 Eye-One Display 2?
Thanks for the help.

6500 white point and 2.2 gamma are recommended.
There are two principles to understand -
1. Always purchase a proper spectrophotometer, not a mere colorimeter. The spectral radiation curves for different types of emittive devices are unsurprisingly different. CRT's are different from LCD's and LCD's are different from LED's. These differences are better captured by a spectrophotometer, whereas a colorimeter is optimised and the difficulty is that what it is optimised for is not documented. The X-Rite Monitor Optimiser was a colorimeter, and it worked OK for CRT's but not for LCD's when they came along. The GretagMacbeth Spectrolino and Eye-One could capture the spike red spectral curve in LCD's better. Today, the discussion is whether a colorimeter works well with the green in LED's but I don't follow this except out of the corner of an eye.
2. As long as you have a colour display, calibrated to a stable condition, and characterised in an ICC type MNTR Monitor profile, you can set the white point and gamma to what you want since the ICC framework will match through the D50 illuminant Profile Connection Space virtually. The difficult part is not the ICC framework, which is based on a mathematical model of the illuminant, but how you set up your studio lighting and studio viewing box which are physical light sources and not mathematical illuminants. The original idea is that you set up your studio light sources to 5000 - 5500 Kelvin along the lines of the D50 illuminant, but there are as many theories as there are colour consultants.

27" iMac Display Resolution

I would like to find out which display resolution settings are the default on my iMac 27". Can anyone help me here? I got them set wrong somehow, and can't seem to get them back to where they were before I screwed them up

Thanks so much babowa.
That's the size listed at the top of my list also, but it doesn't depict if it is default setting or not.I'll use it for a while and see if it seems the same. I appreciate your response and help a lot.

Request for optimal calibration settings for Lenovo ThinkVision monitors

I understand one person's settings may not hold true for someone else's given display variances, but I would very much like to get anyone's suggested, optimal picture settings for each of the below two monitors.
Primarily monitor 1 looks way worse than monitor 2 for me, but I still want help with both. Models listed below. Please include each item/setting with # used so I can try them out and see if it helps.
Monitor 1: LEN L1900pA
Monitor 2: LEN LT1913pA
Thank you for your help!

Hi Jwhyrock,
Jwhyrock reply,
I played with settings on all 3 monitors. Not entirely sure I like what I did, but it is a bit better. I would still like to see what settings anyone else is using for their display such as contrast, brightness, color saturation etc.
Below is the link on how to setup the default calibration for display, please follow the steps. And also suggest you to check with resetting the Monitor to factory default setting in the monitor, or you can also check with installing Monitor .inf for the specific model which can be downloaded from the manufacturer link.

Hope this helps!
