IMac :: Enhance Mac's Screen Color/display
Sep 13, 2009
I opened up system prefs to calibrate my screen for the first time so you will need to go to 'Displays' then 'Color' then 'Calibrate' on the side.
It will open up a few tests and when finished make a new display profile, when your done constantly switch between your original profile and the calibrated one (imac calibrated).
You will see a huge difference in enhancement of the screen color lighting and adds more texture, you should look at your wallpaper when switching I chose the snowy mountain wallpaper from snow leopard and it really improved a lot.

I'm working with an iMac, Photoshop Elements 8 and an Epson R2880. I've calibrated the iMac for Adobe RGB; I've set PSE * for Adobe RGB; and I have downloaded the profiles for the R2880 and set it for Adobe RGB. However, my prints look noting like what I see on the screen.

My wife has an iMac (I don't know any other way to identify it e.g. model number), and she has this 3rd party calibration software that I'm trying to use. I am not used to a Mac, and I cannot find the display settings for the monitor. There are no buttons on the monitor, and when I go to preferences, I can only find the brightness control. I've googled this and cannot find a clear, simple answer. I have used every version of Windows (currently on 8.1 on my PC) and it's easy for me on that platform. I suppose it's just that I don't really know how to navigate Mac OS.
Info:
iMac, Mac OS X (10.6.8)

After my 27" i7 wakes up from a long sleep (roughly over 1.5 hours), something very odd goes on with my color profile and/or screen. Approx. 5 second or so after waking, the screen color appears to wash out quite a bit. You certainly have to be quick to notice it, but something is definitely going on.

What is happening to my computer. This is the 2nd time it does this: all of a sudden the screen becomes black with reverse fluo colors.
I have to force quite with the push button & restart it. I repaired the permissions & restarted it. It's working again, but I am wondering if I have an alien in it.
Specs details:
iMac, 3.06GHz Intel Core 2 Duo, 4Go 1067 MHz DDR3, running Os X 10.6.8

I just got an IMac G3 running OS X and OS 9.2.2. I am having monitor problems with it, the monitor has a slight red color on the right side and if there is a light colored box on the screen I get almost a run effect going to the right. This happens in OS X Tiger with all the updates, OS 9.2.2. I also have all the firmware updates, an external monitor looks great.

before switching to Mac, I used an "X-Rite Eye One Display 2" color meter device with software. You can find them most places like Amazon for about $150. The device should still work, but I can't find any software for it for the Mac. After going to the X-Rite web site, I could find no software at all for the Mac as it is only windows based.
Surely someone out there has used a color meter such as this one as they are quite popular especially for graphics artists that use professional graphic monitors. I am hoping someone can tell me how to use my color meter (USB), what software for Mac Leopard I need and how to save the color profile in the Mac OS.

Can someone confirm if an Imac G5 will display on a second screen from startup or does the OSX have to complete the boot process before the second display will work.

I just purchased a Mac Mini and am using a DVI to HDMI cable to connect it to my 42" Sony KDF-E42A10. I am unable to achieve full-screen resolution and downloaded SwitchResX to manually adjust the display. Does anyone know the timing parameters for the Sony or how to achieve full-screen resoltuion?

I have a problem with my screen - when there is something black on, I can see a faint mark of a lighter colour. I have tried to take a picture, please excuse the poor quality. There is nothing visible when the screen is off, even under close examination. Is it less visible when lighter things are on the screen, and invisible when the screen is white.
No drops or liquid spills. Will this go away on it's own? Any fixes?

Thing is I got hold of a 1ghz 17" iMac almost for free, it had a dead logicboard (I checked it with a voltage-meter), but I figured I could fix it and have a small hobby project-thingie going on. Well I just got a new logic board today, for a 1ghz 17" iMac g4.
Things is I only get a bright grey screen from my Mac when I boot. I've tried connecting it to a external display and that works fine. Everything is there.
I then reinstalled Tiger on it, with the computer connected to my external screen. And I still have the same problem. (I have now disconnected the ext. screen and is controlling the iMac from my MBP). So at least it isn't the installation.
So what is the problem? I can via an Apple Keyboard control the brightness on the blank screen, which would indicate that it does react to input of some degree.
I've read that if the inverter is dead or anything else is dead, you would get a rolling grey screen, flicker or something like that and not a steady bright grey. One thing I'm thinking is. What if somehow this logic board was for a 15" 1ghz imac g4? Can I check this?
I read that long thread about guys buying hi-res displays for their MBPs, and they had to replace some display profile? Could I maybe fix it with a different display profile-file?
I'm really confused by all this, and would appreciate any help I can get.
Model: PowerMac6,1
CPU-Type: PowerPC G4 (3.3)
and
the gfx chip is a GeforceMX4 with 32mb.
The display is a mode 9c27, manufacturer 610, serialnumber 00000, manufacture date: B84D7200.

I own an early 2008 iMac running Snow Leopard. A few months ago, it started getting a little buggy and running slow, you know, things you would expect from a computer that's now 2 years old. But then it started freezing and giving me "kernel panics". Of course, the first thing I did was install VirusBarrier and remove any and all viruses it could find, and I repaired the disk and disk permissions and ran all the diagnostic tests from the install DVD. Then I left it unplugged for a day, upgraded the memory from 2 GB to 4 GB and did everything a second time. After all that, everything seemed to work just fine.
Now it seems to be starting all over again! This time the virus scan only picked up a few Windows viruses on an old external hard drive and repairing the disk, disk permissions, and running diagnostics turned up nothing. I've done everything I know to do, short of taking the thing back to Apple! Right now, the main issue is this bug at startup that's really just freaking me out. Linked is a video of what happens. The apps that run at startup are BumpTop, HughesNet Status Meter (as of last month), and Brother Printer Utility. [URL]

I have an iMac G4 running 10.4.11. (not intel). When I turned it on today, it was all pixilated, little white squares in between the colored ones. I can hardly make out what is on the screen so I can?t really choose anything using the mouse. Everything else seems normal except for the the screen.

In display in system preferences there is a tab with "Millions," "Thousands," and "256" colors,but 256 colors is dimmed. How do you set your MAC display to use 256 colors so I can play an older game?

so this has happened twice now in the past month, my mb is in screen saver mode and i wake it up to find that the color is off in the screen. meaning that the color settings changed and the screen has a swashed out blue tint to it. first time i restarted and all was good, second time i clicked on the preferences icon and then the screen went back to its normal setting. my normal setting is not the factory one but one of the ones that people said makes the screen look better.
so what gives, is the integrated chip dieing on me?
oh its a unibody that i got when they first came out, 2.0 processor one all factory

Just got my new cinema display -- loving it so far! Has anyone gotten around to calibrating their displays yet? I've seen similar threads in the past and found the profiles posted by folks to be pretty useful. If you have a good profile, please post it here!

Specs: I have an IMAC G5 Power PC. The display is 20 inches and the processor speed is 2.0Ghz. I have 512 megs of RAM and 250 Gigs of hard drive space. I purchased the computer in the summer of 2005 and until now, it has worked like a gem.
Problem: My display does not show any picture or color. My wife told me she saw infared-like colors while using the computer and then it went completely black. I booted the computer in transfer mode and used my lap top to transfer all the files off the computer.
I then followed the troubleshooting procedures on the webpage [URL]. All the LED lights come on and I do not see any dim light when I examine my computer at an angle.
After the screen went blank, I purchased the VGA adapter cable and plugged in an external monitor to the computer, but I didn't get any picture on the external monitor, probably because the adapter mirrors what is on my screen. I had hoped I could completely transfer the picture to the external monitor, like you can do with a laptop, but I couldn't figure out how to do this.
Questions: What is wrong with my computer? Is is possible for me to use an external monitor even when the computer display doesn't display any picture? If so, how can I do this?

I have an early 2011 Macbook Pro, the higher end model with Snow Leopard. Before that i had a late 2008 unibody aluminum Macbook with Leopard. As soon as i started using my 2011 MBP i noticed the screen tone was much warmer than on my 2008 Macbook. all the colors look over saturated. i tried to change the color profiles, and the calibration tool, but it still looks horrible. i will try to post a picture showing both screens side by side so you can see what has been bothering me for a whole year now!
Info:MacBookPro, Mac OS X (10.6.8)

For the past few weeks it has been going to a black screen when trying to wake it up from sleep. Either I've put it through too much work lately editing all these photos and its really tired. So, often it wakes up normally and functions fine, well, not really. It is seemingly very slow. It requires a lot of time (more than before) to open up a program or it gives me the "spinning wheel of death" when trying to go to a different page on the internet or open up a folder on my desktop. Amongst other things that require it to think. So It's just a lot slower in general than before.

Which monitor has better resolution... an ACD or the screen of an iMac?
I'm asking this because I'm thinking on selling my 30" ACD and my 17" MBP so I can buy a 24" iMac and a 15" Macbook Pro
