Dual display colour variation.

I had 2year old 23" ACD , i bought New 23" ACD (same model, not LED model). And placed both togather for dual view.
Now the problem is that color of new is more bright and white while my old ACD panel shows warm and dull color.
Is there any ways to repair/calibrate old so i have same color in both the LCD...?

Hi macboydesign
Welcome to Apple Discussions
Lots of practice!
Not included in the current lists there were a dozen other DYI profiles between the iMac and LG that were so bad, I had to delete them.
The following article is dated, but has some great tips and info:
http://www.computer-darkroom.com/colorsync-display/colorsync_1.htm
Oh' almost forgot to mention, uncheck that box "Show profiles for this display only" and try some of those sRGB and RGB profiles to see if you can get closer that away.

IMac Dual-display colour profiling on second LG monitor

Hey guys,
I just purchased a second screen for my imac to use dual display, im a graphic designer and really need the space. What is the easiest and best way of mirroring the colour setting of the iMac to my second screen without the use of 3rd party colour calibrating software?

Colour management warning for dual display users

For those of you who require a colour managed workflow and have more than one display, be very careful in Mountain Lion. It appears to have a bizarre bug where images loaded and shown on the primary display (e.g. in Preview) are initially rendered with the colour profile from the secondary display, or something along those lines. Dragging the display window to the secondary display and back again sorts things out. I've filed a bug report.
If your two (or more) monitors have the same colour profile, you won't have a problem. The only workaround I can see is to set your least important display(s) to all have the same profile as your (probably calibrated, if these things matter to you) primary display, at least until (if?) the bug gets fixed.
If you want to see it for yourself, set your two displays to differing profiles - e.g. NTSC (1953) on the primary and Wide Gamut RGB on the secondary. Then load an image into Preview - something with lots of shades of red "works" well for the colour profiles mentioned. Take a screenshot of the Preview window as a reference. Move the window to the secondary display; note the colour shift as it gets re-rendered. Now drag it back to the primary display. It'll look quite different compared to the screenshot you took earlier, despite the fact it's the same image being shown by the same application on the same display in the same window... All you did was drag the window between two monitors and back again.
It doesn't seem to matter if the image in question has a colour profile embedded in it or not. When comparing with your screenshot, feel free to drag the screenshot between the monitors too - after all, it'll be suffering the same rendering bug! You'll still see a different result; in fact it may even be magnified by the accumulated rendering errors.
Preview isn't the only application affected; I've seen identical issues under harder to replicate circumstances in Safari, for example.
Given this fault and others I've seen with colour rendering in Lion, plus several new bugs found in Mountain Lion, I'm afraid that if a colour managed workflow is important to you - well - Snow Leopard or Windows...?! Ugh, what a mess

I've encountered many of the same woes with color management being a graphic designer, but here's my issue:
Have a 15" (Early 2011) Macbook Pro. It is turned on with me hooked up to my Dell U2410 and display open for a dual display configuration. The Dell is my primary monitor.
I then unplug my MBP to use it around the house. I go to plug it back into the Dell for my dual monitor. I notice that the color on the Dell looks good, but now the MBP has a very blue color temperature. Like moving from the preconfigured 'Color LCD' profile to 'sRGB' which definitely shifts to a blue color on the MBP.
I check the color profiles in System Settings and the Color profiles are correct. 'Dell U2410' for my Dell and 'Color LCD' for my MBP. But as I said, it's much bluer than standard. I try to change the color profiles around on the MBP and no matter which I select it's always the same color with no shifts I would expect to see.
Only solution I have found is to restart my computer. Upon restarting all is well again in the world.
It's pretty annoying having to restart my computer everytime I plug it back into my workstation with Dell and keyboard.
Related note: USB does not work when I plug things back and again have to restart to fix this.

Massive colour variation from Aperture to Photoshop

Hi there
I have experienced a startling colour variation when exporting an image form Aperture to Photoshop 3 (for a bit of tweaking).
Please see this screen grab which shows the variation - particularly the desaturated reds in p/shop:
http://www.white-adams.co.uk/white-adams.co.uk/ScreenGrab.tif
(although the screen grab is less dramatic varied than the reality on screen here).
Some background:
File is a raw file with some basic adjustments made in Aperture
I then right-clicked on the version made in Aperture and selected "edit with" Photoshop CS3
Can anyone help me explain the variation?
If I want to get this image printed and I export it from Aperture will it retain the lovely saturated reds - or look more like the photoshop version?!
Help!
Kind regards
Robert

have checked soft-proofing is off in Photoshop
Configuring Photoshop for compatible assumptions is complex. The first ICC-enabled version was 6 and it introduced dialogues including Colour Settings, Proof Setup, Proof Colours, Print with Preview > Colour Management on top of the old PostScript colour management model and the even older PostScript level 1 model where transfer curves and frequency algorithms get programmed into Encapsulated PostScript and change the calibration of the raster image processor at runtime.
The controls are here and there technically non-sensical. A couple of critical controls are Simulate > Paper White and Simulate > Ink Black. The English is non-sense, so the localisations are non-sense. If EU localisations are inverted back into English, they read Simulate > White Paper and Simulate > Black Ink - including the German localisation that one would suppose the good people at Heidelberg, FOGRA and Bundesverband Druck und Medien would have had their beady eyes on.
Why is the English technical non-sense? Because in a colour test chart there is a null colourant patch where the spectrophotometer measures the colour of the paper itself (its L* lightness and its ab hue and chroma); a patch where the colourant combination is C100 M100 Y100 K100 which is where the spectrophometer measures maximum process black; and a patch where the colourant is K100 where the spectrophotometer measures black solid and solo.
Process black in C100 M100 Y100 K100 is what Photoshop uses in Simulate > Ink Black and the colour of paper measured in the null colourant patch is used in Simulate > Paper White. There were discussions with Adobe in 2004 and again in the following, but I stopped trying to get them to change either their localisations or their source English - let alone the multiple modal dialogues for controlling rendering intent configurations.
With regard to Aperture, the idea of allowing the enduser to apply a gamma correction on top of the colour management input-output is not a good idea. It helps the one person who doesn't have proper studio lighting for a display-print match, but it does not help the colour management process with other people in a workgroup.

Bridge and dual displays

I have been searching the web for a while now to find a way to show the usual Bridge window on one display and a preview - just a preview... no menu bar or other embellishments - on the other display in a dual display setup.
Apple's Aperture does it but I can't find a way to do it with Bridge, nor does it appear that Lightroom will do it.
I think this is a significant setback... being able to do this would be great for editing so you could see the image preview with no distractions and as big as possible. More to the point it would be good for presentations so the presenter can see all the folder structure, favourites, thumbnails etc but the audience only sees the intended image on a clean black (yes black... not the image backdrop colour) background.
I have found a way to cheat this, by extending the Bridge window over both displays and positioning all the favourites, folders, thumbnails panels etc on the extreme right side but you still see the menu bar and other bits and bobs at the window edges and the background colour is grey, not black (unless you set the image backdrop to black, which I think is a bit harsh for viewing thumbnails).
If you want to see what I mean, go to http://www.2020graphics.com.au/dual_displays.html
If anyone has any ideas on how to do this, or any Adobe engineers are reading this... help!!!

>Select an image in Bridge. Then hit the space bar on your keyboard.
 
 This is what you get:

Full Screen Preview Space
 nothing but your image on the main monitor, your secondary monitor totally blacked out.
 
 You can use the arrow keys to navigate through the images in the folder. Use the escape key to go back to regular view.

Setting Photoshop monitor profiles when using dual displays?

I'm using a Macbook Pro connected to an Apple Cinema Display under OS 10.5.8. Both monitors are calibrated and I export from Lightroom to Photoshop in ProPhoto. The Photoshop working colour space is also ProPhoto so there is no mismatch there.
When in dual display mode I like to have my Photoshop application on the Macbook screen and the photo I'm working on shown on the Cinema Display. In fact, I couldn't work any other way because the laptop's screen is not at all suitable for precision work.
I noticed that when I send an image from Lightroom to Photoshop CS4 for further editing the colours were off in Photoshop. This lead me to check the monitor profile used by Photoshop and I saw it was using the Macbook Pro .icc profile. This seems to be used even if the image is displayed in the external display. Selecting the Cinema Display as "default" in ColorSync doesn't change the situation. As a result, the colours as displayed by Photoshop are incorrect.
The only "solution" I have found is to either go to System Preferences > Displays and select the external monitor as the principal one (which is inconvenient because it negates many of the advantages of using dual monitors) or setting the Cinema Display's .icc profile for the Macbook Pro as well (which makes it the one chosen by Photoshop but means I'm only working wiht one correctly calibrated monitor).
Is there a solution to this problem? Ideally I want to have both my monitors calibrated and Photoshop detect which one I'm using to view my photo. Failing that, I would like to have both monitors calibrated and "tell" Photoshop to use the Cinema Display as the principal monitor.I don't want .
Many thanks!

Thanks for your reply!
I'm not too worried about 10.6 because I'm not using it ( I reverted to 10.5.8 precisely because of the colour issues).
I don't really understand your reply. My problem is that if Photoshop uses my Mabook Pro profile as the "monitor profile" my pictures - as displayed on the Cinema Display - look different in Lightroom and in Photoshop. It's as if Lightroom is "aware" of which of the two displays is being used whereas Photoshop can only deal with one at a time. I would like to know if this analysis is correct and what I can do so that Photoshop displays my photographs the same way as Lightroom does on each of my two displays.

Wacom tablet on dual display dual card setup...

...and the cards are as follows, one Geforce GTX 460 (nvidia driver), one Radeon x1650 (radeon driver) As such, I have to use Xinerama and not RandR for my dual display setup. I have configured the driver to use my main display (Dell CRT on GTX 460) and the cursor shows up where it's supposed to, but when I draw, the cursor "splits" into two, the actual cursor, and the drawing cursor. The regular cursor moves as if it's on my main display, but the drawing cursor spans both desktops.
I've tried all kinds of things to make it work, no luck though.
xsetwacom set "Wacom Graphire4 6x8 stylus" Area 0 0 30408 12064
xsetwacom get "Wacom Graphire4 6x8 stylus" MapToOutput HEAD-0
Both of those commands produce the same result, which is shown in the video below.
xorg.conf
http://pastebin.com/d0TSwNrR
And a lovely video showing what I mean.
http://www.youtube.com/watch?v=YMGGehD81jM
Any help would be lovely.

MisterAnderson wrote:Honestly no clue how to help you, but I am interested in your setup. Are you using the proprietary drivers for your nvidia card and the opensource radeon for your ati? How did you get this setup working? I've been trying for ages!
If I remember correctly, I just used --nodeps and maybe --force when installing the nvidia driver, that way it didn't force me to uninstall the radeon driver when I install the nvidia driver. Then, look at my xorg.conf. there's no acceleration of any sort on the ati card, but I can use it for terminals and browser windows, text editors and the like. Can't watch flash videos on it though, and I don't think mplayer works on it either, I'm not at my arch box atm, so I can't verify that.
Also, as mentioned in my opening post, no composting either. The same setup works pretty good in Ubuntu with a similar config, but no compositing there either, Unity clones 1680x1050 of my main 2048x1536 display, can't split the desktops, and I just end up using Xfce4 because it handles Xinerma pretty well.. I have to turn off the compositing extension in the config on arch to get X to even start up.
:edit:
back in arch, should note that whenever I install a new package, I receive this warning. Everything still works tghough as I describes. And back on topic, anyone have any clue as to why my tablet behaves this way?

According to the copy&paste from wikipedia, HDMI should support higher resolution than 1920x1200. So the question is, does it aupport that on the mid 2011 mac mini. It says in the specifications
"Mac mini is designed to work with HDMI devices that comply with versions 1.0, 1.1, 1.2, 1.2a, 1.3, 1.3a, and 1.4 of the HDMI specification."
That should mean it should be able to support it, but I don't know : <

You can't do it. This has been an issue since Lion.

Dual display color and other related issues...

I have posted this on painter forums, though some of the issues coming together here are directly related to issues w/ Snow Leopard and dual displays. Thought I would try here....
This is so bizarre. When I ever I run P11(I think this is going on in P10 too?) w/ the OS X (snow leopard, 10.6.2 on quad core Intel Xeon Mac Pro, 10 GB of RAM) menu bar on my Eizo(making it the main display), and the Apple Cinema display left as the #2 monitor, I get very annoying brush cursor artifcats left randomly on the Eizo screen after strokes. One cannot predict when the cursor will leave it's gray "marks", but it will do it, sometimes 5 strokes in a row, sometimes after 15 strokes or so? If I move my brush back over them, or change the image percantage view, they vanish, obviously new ones coming back, as I work.
However I put the OS menu bar on the AC display, yet work back on the Eizo, this does NOT happen. No cursor artifacts. Well, at least I can summon the issue
The reason I am doing this is Snow Leopard has bad color issues w/ dual displays (well documented, much to Photoshop CS4 users frustrations, and mine). Apple needs to fix it... but for me to see the right color on the Eizo(this is my main color and superior display), it needs to be the main monitor(menu bar) in 10.6.2.
So, you can see my trap - Accurate color, or annoying cursor artifacts left on the screen (sorry, it really bugs me as I work) as I work in Painter.
Attempted fixes: Trashed all of Painter's prefs, all of Wacom's Intuos 4(latest driver) prefs and software, switched plug ins on the back of the mac for the displays(lots of restarts), ran cache cleaning Cocktail and DiskWarrior, etc. -- no change, as I can duplicate the issue w/ the above set up. A sidebar or maybe be very related note: I have an iMac w/ max amount of ram (model not very old -- maybe 1 or 2 old) and I have had a long standing issue working on the iMacs we have had w/ this brush cursor artifact problem (in Leopard and Snow Leopard). I am on one monitor w/ the iMac, so you know here the menu bar is...hmmmmmmmm.....?
Thanks!, T

Possible to do dual display with a mini?

I have an early 2008 Mac mini (Intel) - with the standard DVI connector; using the supplied DVI/VGA adapter to connect to an LCD monitor.
I'm just wondering if it is possible to use two displays with this model and if so, how do I connect the second monitor?

Several ways of doing it in this thread:
http://discussions.apple.com/thread.jspa?messageID=8335705&#8335705
If you want to go the usb route, see also:
http://eshop.macsales.com/item/Other%20World%20Computing/VIDU2DVIA/
Be sure to examine the limitations of each method.
(I'd also consider that your 2008 Mini likely has substantial resale value and that you might prefer getting a 2009 Mini which natively supports dual displays.)

Dual Display on Mac Mini

Hi there,
I want to have a dual display setup with my Mac Mini. There's also a twist. One of the displays is a regular monitor. The other display is a 46" TV. I am not too technically minded - is there a splitter or some kind of dual display "kit" I can pick up?
Thanks!

Which Mac mini? The new one has two video outputs on it, so two displays is not a problem.

Dual Displays and Windows XP

Hello,
I have a MBP with the Radeon X1600 graphics card. Under OS X I can run dual displays without a problem, either extended or mirrored. Using Bootcamp to boot to Win XP, I can only get the 2nd monitor to run extended, I can't get it to run mirrored. What really drives me nuts (short trip) is that I have run it in mirrored mode before when I teach. I go to the Display dialog box and "see" both monitors, but the only way I can get anything now on the 2nd is to run extended? I could update Radeon driver on the Windows side, but I thought BootCamp took care of that and I don't want to mess up my laptop?

It is definitely best to reinstall anytime you make a major system change. You will have to do at least a windows repair although I am not sure if it will fully enable the dual core.
Good Luck
Jeremy

Dual Display - help with Cinema Display for MacBook Pro where MB won't detect displays.

I just got a Cinema Display (a1081 20") ("CD") off eBay to use as a dual screen with my Macbook Pro OS X 10.6.8 ("MB"). However, I can't get MB to recognize CD! I've tried power cycling both the MB and the CD with and without USB cord connected. MB won't recognize CD display in any situation. However, it is recognized in some capacity although I can't use dual display because the CD power button triggers MB to ask me if I want to restart, shutdown, or cancel.
Any help is appreciated!!

Have you tried smc and pram resets?
Try Detect Displays in the Displays preference pane.
Does the Displays preference pane Arrangement show two screens? If so do click gather windows and check the resolution setting of the new screen.
