OS X :: Colour Profiles - Imac To External Monitor
May 2, 2009
I have just bought an external monitor to make a dual screen set up with my imac. So for the first time I am looking at the colour profiles. Would I be right in thinking that if I select profile "sRGB" on the external and "sRGB IEC61966-2.1" on the iMac then when I have the two screens side by side, the colours will match? I have using the Apple 'iMac' profile for two years and anything else just looks strange. What is the 'true' colour or is it just a matter of opinion? Which profile is nearest to real life?
I screwed up. Or I'm too poor to do things right. I bought a Dell E178WFP, 17" 1440 x 900 @ 60 Hz, 32-bit color external flatscreen. And I live in Egypt and can't take it back. I should have bought an Apple cinema display, but it would have been five or six times the price. The problem is its colour profile. I set it the same as my powerbook, to LCD Color, but it still looks like a PC screen, and I hate that. One of the reasons I love mac is the subtlety of the colour of the screen; it is calm and has depth, unlike PCs which always look garish and brash to my eye.
Is there anything I can do? I explored the color settings, but so far can find no way to actually set the external screen in a way that it renders like the main screen of the powerbook. Ideally, I'd have them both near enough the same. Theoretically, this should be possible, no? Given that I'm running the external off my mac, and that it's a simple LCD that can render millions of colours...........
After switching from David's Profile (which was meant for a MacBook anyways not an iMac) to Colour LCD on my 20" Aluminium, I could not believe how dark David's Profile is. I have seen some 20" Aluminium iMac colour profiles but like 95% of them are for 96CA panel not 96CB (which I have). Does anybody have good colour calibration profiles for the 9C6B panel?
use this thread to post your MacBook Air colour calibration profiles. I am sure a lot of people would like to try some profiles on their MacBook Airs'.
I have a 27" i7. I have a 24" DVI Montior hooked up to it via MDP->DVI adaptor. When the 24" Monitor is on, everything is fine. When I turn the monitor off, the magic mouse tracking on the 27" screen stutters. I am not kidding - it took me ages to figure out that to fix I either need to turn the other monitor on OR disconnect the MDP->DVI adaptor.
what's happening here? Under Snow Leopard (this didn't happen before) when I change the profile of my MBP-screen the colors of my secondary monitor (BenQ G2400W) change randomly. This happens when using the topmost profile on the secondary screen. This means to me that I cannot use that profile because it's somehow multiplied with/overridden by the primary monitors profile. This topmost profile (named after the BenQ G2400W) happens to be the best (was in Leopard) so it's quite messed up.
I've been trying to get decent color on my Acer AL2216W display to no avail.
First, I attempted to fiddle with the brightness and contrast levels because I've been having trouble seeing really light grays. I used this as a guide so my whites, grays, and blacks looked good but then my colors were completely off.

Then, (after resetting all my changes) I downloaded a color profile from the Acer support website. Surprisingly, that profile is completely off.
Next, I tried using Mac OS X's Color Calibration utility in System Pref > Displays > Color > Calibrate. I ended up with incorrect colors & grays again.
Am I doing something wrong? Could someone please direct me about how to achieve proper colors and contrast?
Also, if any of you have an Acer AL2216W and you have made a correct color profile, please pass it along!
New to using Mac's... this is an older desktop but I haven't had any issues with it yet. I went on to use it and the colour was a yellow/orange looking colour and it changes the way pictures and text look on the computer. Is there a way I can troubleshoot this problem or is it something to do with the monitor itself?
I have a 27" Imac and want to use an old 19" monitor as an external unit. I have it hooked up and turned on. Just the old wallpaper shows on it. There isn't an icon or anything diff on my iMac screen for it. How do I use the external? I realize this is pretty dumb, but I'm a newbie here and my Mac expert son is in NC....
I have a newer iMac 24" bought in 11/2007. I have the mini-dvi to vga converter and when I connect it to a external tv capable of 1024x768, the iMac freezes and does nothing. I disconnect and the screen turns blue and the flickers back on and everything works. I have made the connection then booted up, and I have tried every resolution all the way down to 640x480, same thing it just locks up the screen, but again as soon as I unplug the mini-dvi to vga cable from the iMac it flicks to a blue screen and everything comes back. I have reviewed dmesg nothing, and revieiw /var/log/messages. Is there any troubleshooting I can do. I am old school unix/linux guy just converted my family to Apple and would like to use the display on my tv to watch my iTunes movies.
Upon booting the machine, the LCD display flashes a proper view of the login screen for about 1 second but then goes dark. When an external monitor is attached the external monitor works perfectly fine -- the only trouble being that the external monitor is not currently set to "mirror" so it is impossible to log in and access the machine. The IT dept at the institute has a monopoly on repair of computers and so the quick answer -- take it to Apple is not all that easy. Is there a way to:
1) set the iMac to mirror display upon booting up by some clever key combination? 2) set the machine to mirror by remote access and command line methods? 3) mirror by changing something using target mode? 4) or the obvious...somehow login using the real estate provided by the external monitor.
Also has anyone seen this problem with iMac displays? An Intel iMac I think 2.16 Intel Core 2 Duo processor running Tiger.
I heard this is possible, however will it be possible with a windows laptop ( dell e6400) It's a work laptop and wasn't sure If I could do this with some sort of adapter.
Title says it all...how does the new iMac work as an external monitor? Is there a way to use it as a monitor without having to log in / load OS? Is there any delay as compared to a standard monitor? I'm just thinking long term as the iMac becomes long in the tooth and we move on to new machines. Can the iMac still be used as a quick turn on monitor or do you need to load up both machines (and do you need to rely on all parts functioning in the iMac, such as mobo, hard drive, etc. still working) to utilize it as a monitor)?
I am iMac 27" owner and I would like to know if it is technically possible (how?) and advisable to connect a PS3 (or other videogame station) to show it in the iMac 27" display.
On my 2008 24inch iMac the screen has a problem ( dead pixels ) and I will get it replaced in the future , in the mean time I have a very nice large external monitor connected to the iMac which I use ok, what I am looking for is a way at first when booting up , to be able to see both the iMac's screen and the external monitors screen , then some how shut off / make blank the iMacs screen only leaving the external monitor on ?
I have an iMac that I keep connected to an LG HDTV via Mini-Displayport to HDMI. I was wondering if there was any way to disable the external monitor without unplugging it? Turning off the TV doesn't actually disable the monitor as I still have the OS thinking it's still on therefore spaces imitates it as being two monitors when its really only one. The main reason I want to disable it is to save my VRAM while I'm playing Source games on Steam.
I want to hook up my new monitor with my 21" Imac. I have bought this mini displayport to dvi adapter. [URL]. What dvi cable should I buy? The adapter is dvid single link, but according to wikipedia the conector is dual link?
I've been given (!) a G5 iMac which is practically brand new. It's only problem is that it suffers from the sudden shut off issue which seems to plague the G5 thanks to a faulty Power Supply and some caps on the mobo which get taken out by the PS. I've replace the power supply, but can't afford to get the mobo fixed, and since neither Apple nor any of the alternative operating system makers such as Linux will be supporting this system into the future, I figure that the hardware is essentially orphaned. I'd dearly like to use the screen though, as it's in great shape and is a beautiful display. So, my question is, can the internal screen be connected to an external source such as the video card of another computer? It would be great to use it for my music production machine. If anyone has any ideas, let me know. In the meantime I'm going to have a look around inside this beast and see what I can do.
I'm looking to turn my new macbook pro into an external mimic monitor for my new imac. ...like, so that I can move my mouse from the imac screen to the pro's screen. How do I do it? Is it possible to do it wireless?
I searched the forums, but it doesn't appear as if this question has ever been sufficiently resolved...so I am going to raise the question again. I apologize in advance if I somehow missed a thread.
I have an iMac (20", 2006 model, Intel Core Duo, etc.) that is in excellent, working condition...aside from the fact that it didn't like having its face smashed in. The screen is almost completely covered with the weird leaf-like pattern that forms in such situations...and is thus, unusable at this point.
Can anyone tell me, without a trace of doubt, if it is possible to hook up a new LCD monitor to the iMac and use the old, broken unit as a CPU? If so, what will I need? Has anyone actually done this?
Conversely, would I be better off simply selling the iMac for parts on eBay and putting the $$ toward a shiny new Mac?
I bought the mini-display port to dual link dvi adaptor for $99. However, it doesn't work from going from my pc to the imac or from my macbook pro to the imac. I find it retarded that they wouldn't even sell a working adapter.
Has anyone gotten this to work or does anyone know which adapter I can buy to get this going? Again.
-PC to iMac -2009 (pre-minidisplay port) dvi to imac.
I need it to be dual link dvi because I want to use it at max resolution.
I have set up two profiles on my new IMac. I now want to access two different itunes accounts but when downloading the second account I get a message saying the computer is already set up with an apple id and if you download you cannot auto download !! for 90 days ??? I don't understand this.
I'm looking for a external monitor that is compairable in brightness as my iMac's screen. The brand needs to be Samsung, and the look of the Samsung moniter I would prefer to look like the examples below. Why? Because I want it to match my TV. I'm also looking for a small monitor because the space I have is pretty small and I dont want to have to move my iMac and look at it at a angle. I currently have a Samsung SyncMaster 906BW with a 1440 x 900 60hz resolution and its VERY dull compared to my iMac and its at 100% brightness and 85% contrast. Here are some of the screens I'm looking at so far, would they be close to as bright as my iMac's screen?
I want to run an Imac and an external Monitor, but I want to use the complete graphics power on the external Monitor, so no mirroring of the displays. Is there any way to shut down the internal display?
Is there a way to disable the external monitor? I don't want to have to unplug it every time I want to disable it... There must be a way. What options do we have?
