How do you calibrate an imac monitor?

Hi, I understand how to calibrate monitors; what I don't understand is why the imac has no controls; except brightness under the display. Don't even know how to set this. Is there a factory reset? Where are all the other controls; kelvin; contrast; ect?????
Even the cheap monitors have more controls to them. Frustrated photoshop user! Jon

Hi there,
Brightness can be controlled using F14 and F15 keyboard shortcuts...
Under System Preferences > Displays > Color > you can calibrate any of the existing Display Profiles > Calibrate... here choose EXPERT mode, this will give you what you want, go through steps adjust as you like > but name as something else, this way you won't over write an existing profile...
Contrast can also be adjusted > Sys Prefs > Unviversal Access > Seeing > Display, here you will find a contrast control option...
I am not sure what you want to adjust back to factory? But there is a place you can do this, Open ColorSync utility > Devices > Displays > Imac > toggle the Current Profile, you will be able to set Factory or Other..
Good luck, Rick

    Normally, you just connect the monitor to the MacBook using a VGA adaptor that you can buy from an Apple Store.  Now try System Preferences > Displays > Detect Displays.  You should now be able to select a display mode for the monitor.  If it still doesn't work, then I'd check that everything is properly connected.  I've had problems with colours disappearing due to a faulty connection in the VGA adaptor.

  • Just got new macbook pro, how do you hook up 2nd monitor?

    Just got new MacBook Pro, How do you adapt to 2nd monitor?

    You will need a Mini DisplayPort (Thunderbolt) cable and an adaptor for the type of connection your monitor requires. You will find the adaptors at Apple's online website.

  • How do you calibrate the iPad battery?

    How do you calibrate the iPad battery and is it necessary to discharge battery 100%. I have  the 3 rd generation iPad, it has been almost a year since I purchased it and the battery when fully charged reads 100%. Recently, I visited my local Jump Plus store and the staff said I should drain the batteries on my iPad & iPhone completely until they are dead and recharge once a month. Is this accurate?  It is my understanding that you should not drain the batteries completely? Also, is that the same as calibrating the battery?

    For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

  • How do you calibrate a computer and a printer?

    I Have calibrated my iMac using Spyder4 and find it still isn't calibrated to print the same colours as my Epson Pro4900. The computer shows a more vibrant colour than the printer prints. Both are set to sRGB and printer controls colour, the way Epson suggests. I'm using PhotoshopCS6.

    Hello Kootkid
    A display has always more vibrant colours than a print, given that it is a light source, while a print is a reflection.
    Having a Spyder4, be sure you calibrate with the ambient light compensation and do a SoftProof in your image editing tool.
    Also, have a look into this eBook, which is also from Spyder:

    A good crash course so far.

  • How do you plug a VGA monitor to a Mac mini (mid 2011)

    I used my older Mac mini (mid 2007)  with a VGA LCD monitor through an "DVI to VGA" adapter with no problems.
    However, this older adapter does not fit in the "HDMI to DVI Adapter" supplied with my new Mac mini (mid 2011).
    There are no receptacles (holes) in the "HDMI to DVI adapter" for the four pins located around the flat tab on one hand of the older adapter .
    Any suggestion on how to plug a LCD VGA monitor to a mid 2011 Mac mini?
    I know there is a Thunderbolt port and a HDMI port,
    but being able to use an inexpensive VGA monitor for set-up and periodic maintenance,
    without having to fire up a huge plasma screen each time, would be nice.
    There is no displayport on this mid 2011 Mac mini.
    There does not seem to be any HDMI to VGA nor  Thunderbolt to VGA adapters on the market.
    Any suggestions?

    The > Apple - Thunderbolt Port is the same as and doubles as a Mini DisplayPort.
    Look down at the bottom of > Mac mini (Mid 2011) - Technical Specifications in the Accessories / Displays and Graphics section or on page #33 of your User Guide.

  • How do you calibrate the touch display on an HP B210a?

    Well, I screwed up. I was messing around in the service menu (stupid me). I hit calibrate touch screen thinking it would be beneficial, but it ended up with me not knowing what I was doing, and now I cannot get the printer to respond to touch. So, how do I calibrate it so it works if I can't get it calibration? Please DONT say send it to HP, I really need to know how to do this on my own.

    I still need help

  • How do you get your iMac to show video (or mirroring) with Apple Tv...please help!

    I have searched this forum, read the articles here and on Google and I still can't figure this out. Perhaps what I'm wanting isn't possible.
    All I want to do is watch my CBS show from www.cbs.com on Apple Tv via my iMac. The Apple TV moniker is next to the volume in iTunes, and I can play music through Apple Tv via I-tunes and have it play on my TV. Thus, I know it is connected and working. I thought I could do a mirror screen like I do with the iPad, but for the life of me I can't find anyone who has covered the subject online.
    Can someone tell me, step-by-step, how to show video from my iMac onto my Apple TV. Thanks so much!
    Confused in the Lou

    If the specs you included about your iMac model are correct, it will not support AirPlay mirroring. See About AirPlay Mirroring in OS X - Apple Support for more about this, including the list of supported models & required OS X versions.

  • How do you connect a second monitor to a MacBook Pro

    i am wanting to connect a second monitor to my MAC so i can have 2 of my pages showing at the same time. how do i do that?

    I am pretty sure the MacBook and MacBook Pro only supports ONE external monitor of any description, even though the cabling will support two.
    The short story, that Courcoul has alluded to but not stated, is this:
    All you need is an Adapter. All the software to do elegant multiple display work is already in place in your Mac, and will be activated automatically the moment you plug it in. Nothing to Install, no settings to change. Just plug in the display.
    The default mode is Extended Desktop, where the one-monitor desktop is enhanced by having the area of the second display appended to its right side (or any other side you specify). The mouse moves freely from one display to the other, and can drag windows with it, which can be resized on the other display. You can even drop things so that half is on each display, and they will scroll and update "the right way".

  • How do you information from iMac G4 to new iMac Intel?

    I just ordered the new iMac Intel and want to know how to get all the information, files, etc. (especially photos) from my old iMac G4 to the new iMac via an external Hard Drive (which I have also just ordered).
    iMac   Mac OS X (10.3.9)  

    You can use the Migration Assistant to transfer the data over; this will appear the first time you turn on the machine, and doesn't require the external hard disk. To use the external hard disk to transfer the data, follow the instructions below.
    Connect the hard disk to your computer, and then choose Go to Folder from the Finder's Go menu. Enter ~ as the folder's location, and then press the Command key and the Up arrow on the keyboard simultaneously. You should then see a folder with a house icon on it; drag this to the external hard disk. On the new iMac, hook up the hard disk and verify that you can open this folder in the Finder. Next, open the Users folder on the internal hard disk and note down the name of the folder with the house icon. Rename this to something else and then drag the folder you placed on the external hard disk to the Users folder with the original name of the folder with the house icon.

  • How do you leave your iMac when you're not using it?

    Just curious..
    Hey All..
    I have a 24" iMac 2.8 with a 750GB Hard Drive. I tend to leave it on all the time shutting it down over night probably once a week. I have my settings to turn the display off after 5 minutes and turn off the hard disks "when possible". I just wondered if this was healthy or will it shorten the life expectancy of my pride and joy? I must admit that I do like to leave it on all the time. I leave my Time Capsule on all the time too...should I perhaps shut this down also?
    I have the Applecare program which gives me some piece of mind with my iMac.
    I'd be delighted and interested to hear how you all 'leave' your iMacs when you're not using them.
    Kind regards..
    ~RICKY

    I have my system plugged into a UPS and generally leave it sleeping. There's a window where I have it scheduled to wake up and then sleep again, but it I otherwise sleep it.
    I suspect that sleep probably puts the least wear on your machine and is safe if you have a UPS. FWIW, an early 2007 24" iMac draws 3W of power when it's off, and 10W or so when asleep ( the newer models use less than 6W). During the boot process, power consumption will go 200-220W for ~1 minute. Normal usage it consumes about 100W. Idling, the machine will use between 70-100W depending on the screen brightness, and about 45W if the display is off and machine is idle. Playing something like WoW brings the power consumption up over the 200W mark.
    The mechanical parts wear proportional to the number of times they are used (physical switches), and the electronic parts wear mostly based on the the result of cycles of temperature changes / surges of voltage. Pressing the power-button to power-on the Mac probably puts the most wear on the unit as a whole. That said, under normal circumstances you are not likely to put enough wear on anything but the hard disk to have it fail.

  • How can you display to multiple monitors using a Mac book pro

    I Need to out put my display to a projector and a vison mixer the projector is VGA and the vision mixer is DVI is there a adaptor that I can  use or hardware that will carry out this task for me

    Sorry, but your Mac can only support a single monitor. Will need to buy a Mini-DisplayPort to DVI or VGA adapter, you will need to decide what you need best.
    The newer (2011 & forward) Macs come with a Thunderbolt port instead, and that supports up to 2 cascaded devices.
