IMac (Intel) :: Change Display Settings Such As Color Temperature And Backlight Brightness On Monitor?
Nov 30, 2014
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.
I need to change the color and brightness for a video file for a presentation and cannot figure out how to change them permanently when I open the video file in Powerpoint. When I open a video which I have altered the AV settings on in another program, the settings revert to the initial settings. Can I edit the color and brightness settings permanently in Quicktime 7?
"A man with one clock knows what time it is. A man with two clocks is never sure." Let's amend that "A man with one display knows what color it is. A man with two displays is never sure." I've recently upgraded from a 1st generation MacBook to the 15" Unibody Macbook Pro and I'm having a great deal of trouble adjusting to the difference between the LED backlit internal display, and my Samsung 22" external monitor. I've probably spent about 8 man-hours going through the display calibrator, and through SuperCal, on both devices, and I can't seem to get a consistent color between both displays. Am I doomed to madness? Will I have to spend money on either a hardware calibration device, or on an LED backlit external monitor? Has anyone else solved this?
I was using my MBP when I noticed that the display (the built in one) looked a little washed out. To make sure my color profile was set to the correct one, I opened up the display panel in System Preferences. The moment I opened it, the display snapped back to its regular appearance. As far as I can tell, it goes into the washed out version after going to screensaver and coming back, and going into display prefs is the only way to restore it. Anyone seen this before or know how to keep it from doing this?
Just picked up a 24" Cinema Display and I'm in love. However, I've just noticed quite a difference in color temperature between it and my 13" MacBook Pro. I've gone through all of the provided color profiles in System PreferencesDisplaysColorDisplay Profiles, but no matter which I select, the two displays don't exactly match.I'm not a display expert by any stretch of the means, and I don't have access to a hardware calibrator. All I can really say is that the Cinema Display seems a bit warmer/more yellow than the MacBook Pro and that the MacBook Pro looks like it might be a bit more red in addition to being cooler, overall.
This may be of interest of more of you. I want to be able to read easier when the background is white, especially pdf files, or webpages.
I did not find a solution for certain documents, to change a background without breaking the style. I'm using the lowest brightness but I found its easier to read when I make the background gray, for example in textEdit.
I have a new iMac 2009 - 24' - 2,93Ghz, running the latest OS.
When I start, the brightness is at maximum... I set it to minimum, only to find it at maximum again when I re-boot the computer ! I tried setting it via settings as well... it just dosent stick !
On the flip-side, the volume retains its last settings.
I have an iMac 5K connected to a second monitor (HP ZR2740W) via mini DisplayPort to DVI adapter. In Displays prefs, I can only select resolutions of Best for Display or Scaled-1280x720 (which doesn't change anything.) I'd like to be able to change to a higher resolution.
Info: iMac with Retina 5K display, OS X Yosemite (10.10.1)
the monitor's default brightness setting is far too bright for my eyes, so the first thing I did was to open the System Preferences pane and reduce the brightness setting. That worked fine until I shut the computer down. On rebooting, the brightness returned to its default highest setting. On my older iMac G5, the brightness setting always stayed put. It isn't a huge problem since adjusting the brightness setting does work, but I don't want to have to adjust it every time I reboot my computer.
I spent two hours yesterday on the phone with Apple support trying to fix the problem, even going so far as to reinstall the system software with no success. The woman on the phone finally suggested that I return the Mac for a replacement.
Has anyone else here with a 2009 iMac experienced this problem? Is it possible that it's hardware related? If so, could this be the tip of the iceberg suggesting a potentially larger problem down the road? I would have guessed it might be a software glitch. (The new iMac has thrust me, finally, into Leopard; until last week I was using Tiger on my older G5.) I bought the 3-year Apple Care with it--since the new iMacs have only been out a week, should I wait until the next Leopard update and see if that fixes the problem?
I noticed that iStat and Temperature Monitor report different temperatures for the same readings on my G5 Powermac Dual Processor System. For example as I am writing this Temperature Monitor is saying My CPU A is 46.8C and CPU B is 46.7C. In iStat it says CPU A is 55C and CPU B is 54C. Which is right!?
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.
All of a sudden, every time I reboot, my screen's brightness is all the way up. So, I go to 'Preferences' and bring it down to only happen again the next time I reboot. Not a terrible problem, I hope, but not sure why the settings of this doesn't remain as I left it last. Perhaps I have picked up something OR I have a fault which could get worse?Anyone seen anything like this?
Does anyone know if it's possible to dim my late 2008 macbook's display more then the lowest setting allows? It seems way too bright in the dark even at the lowest setting, plus I would like to save more battery if possible.
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
A month or so ago, the backlight randomly went out on our MacBook. If you look very closely you can see the screen, but it's like you've got the brightness on its lowest setting. The backlight comes on as normal when you turn on the computer, or wake it from sleep, but goes out after about 2 minutes. Other than not being able to see what's going on, the computer works fine. I took it to the Apple Store, who said they'd have to replace something at a cost of ?75, which was fine. Just over a week later, they called and said that hadn't worked, and that it was actually the logic board that needed replacing, at a cost of ?385, more than the value of the computer. We decided it wasn't worth it.
Yesterday however, I took it to a friends and connected it to his monitor, and even though the screen was dark on the MacBook, it came up fine on the monitor. To me, it seems strange that it's a logic board issue when it works fine with an external display.
Suddenly my iMac's display is very dim - almost can't read the text. The display brightness keys <F2> and <F1> don't do anything any more. How can you adjust the screen brightness?
Info: iMac (21.5-inch Late 2009), OS X Mavericks (10.9.4)
I have an iMac, the screen has gone quite dark (as if in sleep mode) I have to sit in a darkened room to see it properly. Have I hit the wrong key or key combination of keys? How do I adjust the brightness?
I've got two iMacs in my posession currently from getting replacement machines. Both have screen issues as follows: iMac A - dead & stuck pixels, feint grey horizontal bar running along bottom portion of screen, bottom left corner has noticeable backlight bleed. iMac B - dead & stuck pixels, yellow tinge in bottom portion of screen. So here are my questions. Which iMac should I keep and submit for repair? (does it matter and why or why not?) How does the actual repair get done? For example, if I submit iMac B for repair, could I end up with a grey bar or backlight prob like in iMac A?
Are there multiple layers to the display when they fix specific issues? For example, let's say the dead pixels are on one layer while the yellow tinge is on a different layer, or are both issues on the same layer? I ask because if there are two or more separate layers, there is more of a chance to mess up so I may want to submit the iMac that has the least amount of issues.
Lastly and most importantly, has anyone submitted their iMac for screen repair for these issues and got it back 100% repaired? (no dead/stuck pixels, yellowing, grey bar, backlght bleed) These are #4 and #5 in terms of the number of replacements I've gotten now and I'm sick of it so I may opt to go for repair on either of these existing machines instead of going for replacement #6. But do you think a 6th replacement would be better than going for repair on either of these? Or not?
Im using an Imac with Mac OS 10.7.3. I am trying to use a Citrix to open some files but I get the error message that display is configured for 65536 colors and is not supported. I need to us 24 or 32 bit color. I cannot figure out how to make this change. Under system preferences>Display I see nothing that allows me to change depth to those levels.
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.
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.
i really want to customize my macbook. i want to change the color logo to apple classic color. (but not for a while) the main thing i want to do is something like this [URL] the second picture to last. the guy with a suit and a hat, being covered with the apple logo. i want something like that, only not that image. you get the idea though. where can i get something like this? are they stickers as well? or are they laser engraved? i do not want it permanent on my macbook, since i get easily bored with the same look
i've looked far and wide for a way to turn the monitor off on my new imac 24", nvidia 8800, running xp and still havent found anything. does anyone know of a way to turn it off? i've tried to set the "turn monitor off" setting to 1 min under power management and it gets ignored. also, i've even written an app to try and turn the screen off based on this: [URL:...] and it is also completely ignored.
