Problems calibrating LCD.

Help, my LCD is too warm (yellow) and I can't calibrate it away.
I had already noticed my 12" PB display was a bit off colour compared to others but when I recently connected it to an external monitor, the difference was shocking.
Now as I write, I have a 17" CRT Apple Studio Display connected in mirror mode. This web page looks very warm on the laptop display compared to the slightly cool CRT.
I have just calibrated both displays and I was very happy with the calibration on the CRT. Taken in isolation the CRT displays a natural white compared to a white card in daylight.
Calibrating the PowerBook display was not so comfortable. At every stage I found it impossible to get the central apple colour neutral against the background, usually wanting to go further down in the colour space.
Now I have two calibrated monitors side by side and they look entirely different. What can I do?
(Also, why is the PB monitor so rubbish anyway? The viewing angle is about 10 degrees!)
Any help appreciated.

Hi Julia,
I have now tried SuperCal and it is certainly WAY better than the native OS X calibration tool in System Preferences. However, I have since switched to a 12" iBook (IMHO superior to the 12" PowerBook in most regards) and have yet to explore proper calibration on this baby.
As for getting your printer and your monitor to match... whoah, that is a big ask, alas!
Unless you have a professional qulaity printer, you will only be supplied with a default generic coloursync profile and the only way to calibrate your printer properly is (as I understand it) to get a custom RIP - for which you must pay. There are various online providers that supply this service (and some less generic ready-made ones) but remember, you must be consistent in the media you use (ink and paper) to get a truly consistent output.
I have given up trying to really understand colour spaces, coloursync profiles etc and am now rather pragmatic about it.
My monitor is calibrated, I supply image files in Adobe RGB or sRGB depending on the client and for my own printing/proofing purposes I just play around with the colour controls in the print dialogue until I am happy with the output from whatever App I am using and save that as a custom setting which serves as a de facto profile for my printer. It's not elegant but it sort of works. It can use up paper at first but if you are consistent about the way you work it will pay dividends in the end.
Hope this helps,
Gaberdine
Footnote:
One thing to note is that Apple coloursync offers you loads of profiles that are entirely irrelevant to most situations and you need to be careful about which profile you select. Basically it mixes profiles and colour spaces up in an unnescessary and confusing way (as I understand it).
For instance, when setting up a ColourSync workflow, don't set your printer's profile to Adobe RGB or whatever even though that may be the colourspace in which you edit images. Colour Spaces are about the way a potential palate of colours is handled and represented by the computer whereas a ColourSync Profile is about compensating for the way a SPECIFIC hardware device (camera, scanner, monitor, printer etc) is actually capable of reading/outputting colours.
In other words, even if you are working in Apple RGB (which has a limited palate of colours consistent with the hues that printing presses are capable of outputting ... thus saving you fussing about subtleties of colour that would never be noticed in print), you must still set the Profile of your output device to its own calibrated profile or RIP so that it accurately prints off the colours you see on screen. Otherwise it is like wearing contact lenses AND glasses - you don't get a double benfit, you just get confusion!
PS. Apologies to the colour professionals who may think I am talking complete rubbish.

Mac os x font rendering problems 1680x1050 LCD

Hello,
I recently bought a Mac Mini and love it except I cannot tune the font rendering using command line "defaults -currentHost write -globalDomain AppleFontSmoothing -int 1" and using 0,1,2,3 to try out, restarting apps after each change. It seems that "1" is the best setting for my ASUS VW224U widescreen lcd display. The fonts are blurry. Is it that Mac OS X cannot work well with this 1680x1050 display resolution? Anyone have good font display at this resolution?
TIA

I have the same problem.
Changed my mac mini core 2 duo with snow leopard for a new mac mini core i5, radeon graphic card and, of course, Lion 10.6.1.
I kept the same screen a dell U2410 connected on display port.
The immediate result was absolutely awful.
I had to change settings on my display :
1 - the shaprness setting from 50 to 0 (on a scale from 0 to 100)
2 - the color temperature, called preset mode, from Adobe RVB to standard
Otherwise, the fonts were rendered :
1 - very harsh
2 - with very visible subpixels to anti-alias
But even with this new settings, the result is far from being good as it was just before...
I have tried to change font smoothing parameters as you describe in your post but, if i see differences between 1 2 and 3, i found none optimal ... (and kept 2)
I'm going mad !
It could be better with a calibration of the screen (it seems everything is washed out...) but my colorimeter is not compatible with Lion ...

Problem with LCD display on 17" iMac G4

The LCD display on my iMac went wacky on me yesterday. It's as though one of the three primary colors no longer works. The screen has a green tinge to it, and anything that's supposed to be black shows up as green. I've reset everything, run the Hardware Tools diagnostics (no problems found), and changed resloutions, monitor depth, and brightness levels many times. No luck. The screen is readable although very ugly.
Obviously I can take it to an Apple Store, but does anyone have any idea what it might be? I've searched the net and the forums and can't find anything close, but I know I can't be the only one to experience this problem. I called a mac repair shop a few minutes ago, and they said that the logic board would need to be replaced. I just can't believe that because nothing else is a problem.
Please help. Thanks.
17" iMac G4 1Ghz Mac OS X (10.4.6)

I "fixed" the problem a few days ago. Digging around here in the forums, I found another thread that gave explicit instructions on how to open the iMac and re-seat the connections. Here is the link (http://discussions.apple.com/thread.jspa?threadID=196785&start=30&tstart=30). It's a post from Androcles made on 3/26/06.
Just as he indicates, when I did this I found nothing to be loose at all, however upon putting it all back together, on the 2nd re-boot all was back to normal and still is. It's amazing how clear and crisp the screen is after suffering through the green hue for a few weeks...
Good luck, and feel free to ask me for help if necessary.

CALIBRATING LCD MONITORS IN YOUR WORKFLOW

HEY
WONDERING IF ANYONE IF CALIBRATING THEIR APPLE LCDS WITH ANYTHING LIKE THE EYEONE OR PANTONE STUFF BEING THAT THE COLOR OR NTSC DIFFERS AS WELL AS A REGULAR CRT ?
ARE YOU SEEING BIG DIFFERENCES AND WHAT ARE YOU USING TO CALIBRATE THEM WITH.
IM NOT TALKING ABOUT CALIBRATING NTSC MONITORS JUST LCD'S.
G5 2.5,QUAD,MBPRO 17 , PBG4 15 Mac OS X (10.4.8) FCP STUDIO , SHAKE, AE 7

First off, take off your caps lock. Shouting won't get you far here.
Second, I used the Pantone to calibrate my Dell 2405 monitors, and they look good. The stuff I do in Photoshop comes out lookng right.
BUT...you cannot calibrate a computer monitor (LCD or CRT) to match the gamma characteristics of a broadcast monitor. You can come pretty close, but there will be a noticable difference.
Are you trying to use a computer monitor to color correct a show for broadcast?

Problems calibrating compass on iOS 7

I've just installed iOS 7 on my iPhone 4S but I can't calibrate the compass - the ball simply won't roll around the circle. The spirit level works fine, so I imagine it's not a problem with any sensors. Any thoughts?

Ditto for me, also on an iPhone 4s. The first time I opened the Compass app, I tilted the ball around and it successfully calibrated and showed the azimuth. But subsequent attempts at calibration do nothing and after several seconds the app shows the compass dial, but it is frozen. Doesn't seem to be a sensor issue, because other apps with a compass (such as Motion X GPS) seem to work fine. I've tried force quitting the app and rebooting the iPhone, but neither solved the problem.

Problem with LCD hitting the back edge

My Macbook has a problem. The bezel on the LCD towards the very rear of the screen rubs against the base edge when I open up the MacBook.
Here is a picture to describe what I mean:
http://www.flickr.com/photos/47365659@N00/151797793/
That little piece is sticking out. If I open the MacBook from with more force on the right edge, then the tab hits even more and there is enough friction to make an alarming snapping sound.
I hope apple replaces my macbook as I just received it today from fedex!
Has anyone experienced this yet?
Macbook Mac OS X (10.4.6)

I have not had this problem with my Macbook.
I suggest you contact them right away.
I also suggest you don't "ask" them to replace it. I would tell them it needs to be replace. Over time I think that will make for a nasty scar on your notebook. Considering black macbook owners pay 150$ for just the color, Apple knows that how these look has much to do with their value and shoudl approach the problem knowing that.
I hope it goes well, and expect it will.

Problems with LCD in project mode

I am using GarageBand version 4.1.2. Everything works great until I try to set the LCD screen to project mode. When I do so, portions of the program freeze up and I am not able to either use the features in the project LED screen nor switch to another LCD screen,and I end up having to force quit and restart to work any further on the project. When I am in the project screen, I cannot use program menus, transport controls, or pretty much anything, though if I am listening to something it will keep playing. Any suggestions?

there have been a few threads about similar problems relating to missing fonts. you might try searching this forum or the GB 09 forum for "font"

Serious problem with lcd scr

last night i turned off my zen neeon 5 gb and this mornign when i went to turn it on the lcd screen never turned on. the only thing it does is the normal boot up procedure but but theyre is no contrast at all on the screen. i cant read any of the text but i can see the colors when it boots up and when i hit a button and the backlight comes on.
is there a way i can fix it's i have tried hitting the reset button on the side of the device thinking that its being stupid or has locked up but the same thing happends.
the strange thing is that it still plays music. i can hit the play button and it plays a song. is there a way i can reset it to default settings as if i accidently did something wrong with the contrast settings?
any ideas, i need help seriously. huge problem.
thanks.

That would be a wonderful suggestion if my computer could connect to iTunes. Since about July my computer keeps giving me error 11222. I've tried everything on the support discussion board, but they haven't solved the problem either, and my software is up to date. Today instead of giving me the error, it's just been sitting for hours saying "Accessing iTunes Store". I was really hoping that I could just use the wifi on the iPod to access the iTunes and AppStore. Any other suggestions until iTunes gets fixed on my computer? Thanks for your help - Lex

Annoying problem with LCD monitor and noise!!

I have MSI 6330 with 1.2 GHz Athlon (it has a built-in sound card), 384 RAM memory.
I just bought a new Cornea 17" LCD monitor with built in speakers.
When I connect the speakers to the sound card, there is an annoying static-like noise coming from the speakers, like an electric transformation sometimes causes. However, this sound is not "broadcasted" to the speakers, because even if I mute the speakers, the noise is still there, as long as there is a picture on the screen. When the monitor is turned off or shows black screen (such as during start up, or when in power-save mode) the noise disappear. The only way to eliminate this noise is buy reducing (almost to zero) the speakers volume, but then you can cannot hear anything at all, not even sound.
I got a new sound card (I thought it was the sound card problem) - same thing. I connected the monitor to a different computer and the problem is gone, which means - it is something with the computer, mobo, different device....something, I don't know what.
Any one have an idea what this could be?
Thank you.

Hi!
It could be that you have some problem with the monitor.
I have - so far - not encountered a monitor with built in speakers which gave acceptable sound anyway, the easiest solution might be that you will not use the speakers in the monitor (even the cheapest stand alone speakers will most likely produce better sound quality).

Problems calibrating large CRT monitors

Hi All
I have a SP 1.8GHz G5 Power Mac, 1.25GB RAM GeForce FX 5200 Graphics card.
I have recently been trying to find a larger Monitor and not being the richest individual on the planet I have been looking at 21" CRT's. So far I have tried two second hand items, a Dell P1130 and a Sun Microsystems unit. Up until now I have had no colour problems with any monitor I have used. My first an Apple 1705 17", and more recently a Proview 19". Both of these monitors cali brated OK and gave good colour reproduction. However both of the larger monitors I have tried have given problems. The Dell, Model P1130 gave a green/blue colour cast on the picture, the Sun of which I don't know the model No. gave a pink colour cast. No amount of callibration would remove the colour casts from either monitor.
I am concerned that there may be a problem with my graphics card as I don't understand why I should be having these problems considering the colour I get from my current monitor is excellent. The problem being the monitor is faulty and needs replacing.
Is there anyone out there who can throw any light on why I might be having these problems?!
Thanks in advance...

I had a 'yellow' 22" iiyama for years, well 2 and a half; it was one of a pair and eventually I relised it wasn't differences in the graphics cards at all but the monitor which was just darker and yellower than the other. I got round it for that time by using the monitor's own controls to evenout the differences: setting the hardware colour temp very high etc.
Fortunately, iiyama being iiyama, when i rang them they replaced both monitors with new ones, after 2 and a half years! This was all the more remarkable because it contrasts so strongly with apple who only replaced my g5 because it broke within the first 14 days of use: a day later and it would have been sent off for repair; which from what i gather that could have taken weeks.
Try your monitor's hardwar controls.

Help! Problems with LCD Screen.

My iMac's specifications are below.
Recently, I've noticed that there is this large patch of the screen which is covered with white bubble-like drops. I've tried cleaning the display, but it looks like they are under the screen. You cannot see them when the display is displaying white or other light colours. When displaying black or darker colours (even when the display or computer is off) one can see the drops.
I'm not sure if it's because of something I did or what, but I want to know if I should take it in for repair, or if there is something I can do (It's still under warranty).
Here are things I suspect:
My iMac is usually under constant sunlight. It's not directly facing my window, but it does get hit my light. But I haven't heard of sunlight ever damaging an LCD screen.
The drops seems to be in some areas, but not all. Which is why i doubt it's something I have done.
When you get close to the screen, you cannot see the drops anymore. Also, when you are at certain angles, you cannot see the drops. This leads be to believe that a certain amount of light is need to see the drops, otherwise they are too faint.
Any help would be appreciated!
Thanks!

Hello Kuro
Take it to the nearest Apple Store or Authorized Apple Service Center, they can remove the glass panel over the display and clean or replace it if needed.

Problem with LCD computer monitor shots - filmed in HD

Hi All,
We have some shots we took of a laptopn monitor using an XDCAM HD camera. We always have to back the focus off a little when filming otherwise we get a nasty moving pattern on playback. I have a couple of shots where we haven't backed it off enough. Anyone else seen this problem and know of any cunning filter to help out (flicker filter doesn't work) The material is all 1080 25p. (Although I don't know what the issue is, it seems to be the modern day equivalent of CRT refresh rates which we had to fix with variable shutter)
Any ideas gratefully received,
Regards
Richard

Whatever the cause is, the easy fix is to composite a corrected image onto the laptop screen.
This is absolutely one of those "fix it in production" items... or at least I've never found an "UnNasty" filter.
