I have bought this IMAC NEW in decembre IMAC 27

Use a lower resolution with Apple menu -> System Preferences -> Displays.
Adjust the Color gama through the color section there to one that is easier on the eyes.
Do not use in a room with backlighting behind you shining on the display.

IMac 27'' little bit blurry after changing resolution.

Hello. I recently bought a 27'' iMac 2013. As the screen is too big I changed the resolution from 2560x1440 to 2048x1152. But it look a little bit blurry now. 2560x1440 is really good but texts and other thing hard to see. Is that normal? I think Apple should do something about it. My eyes are really fine but even for me it was hard to see texts. They are too small.

in windows one can change dpi of text and the likes in the video settings this partly does what you want
I don't believe it's possible with osx at least not unless one use a thirdparty program
I say partly because while it makes text bigger and easier to read some applications looks a bit odd compared with normal
in osx are some tools in the acccability in system preferences where you get a loop but I never really played around with them'

IMac a little slow on start up

my iMac is a little slow lately and that had never happened before.
I am running OS X Yosemite and I have 1.68 TB free of 2TB
I do not think it should be slow.
Slow when it has been sleeping and I come home and touch the pad and it takes a while for it to wake up.
It takes a while for it to let me enter my password.
Why could this be happening?

IMac resolution problems.

I can no longer select 1920 x 1080 as a resolution option for my external display. I'm using iMac mid 2011 27 " using Mavericks and LG W2442PA. Firewire to HDMI. Has worked for the last 2 years with no problem. Suddenly not. The option to select this resolution is no longer available. I can select other resolutions, but they distort the image and do not offer full screen resolution. I think this may be a problem with Mavericks on the last update. Does anyone have a suggestion?

See the last paragraph of this support article.

Decreasing 27" iMac resolution 2560x1440 into 1280x720

Hi, I was about to change my native 27" resolution (2560x1440px) to just a half (1280x720px). I expected sharp result - just double size pixels without any smoothing. but I got only a terribly blured picture of all graphics on the screen - windows, buttons, my illustrator graphics I'm working on right now... Is there any way how to turn this clever smoothing function off? I need to temporarily decrease the resolution because my tablet is too small for such huge resolution. thank you, tom

Yeah, I know. these two options are about FONT smoothing. I've got problem with all around antialiasing. you have iMac too, Barbara, could you please try to decrease resolution of your screen to just half of it? Is it antialiased? I'll try to upload some pictures in here, thanks.

OSX Maverick iMac Resolution: stuck at 640x480. How do I fix this?

This is my iMac:
- 21.5 inch
- late 2012
- 2.9 Ghz Intel Core i5
- NVIDIA GeForce GT 650M 512MB
- OSX 10.9.2
After updating to Mavericks, the screen resolution somehow got stuck at 640x480 and I'm unable to change it. Going into display settings and holding down the "options" key, does not show ANY display resolution options (see image attached). Any ideas on how to fix this?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

How to get Imac resolution for windows more than 1600x1200

I try to install windows 7. followed boot camp assitant instruction. using usb drive and windows 7 iso. everything seem ok. Installed boot camp in windows ok, But can't get resolution as Imac 2012 native resolution, and can't get adjust volume and brightness either. What's wrong?

try reinstalling just the graphics drivers from inside the folder of Boot Camp drivers, or the mobility driver for your gpu chipset.
same for audio (which is very common issue)

3 month old iMac produces little clicking sounds coming from the top

As of today, my three month old iMac is started to make little clicking sounds! It comes from to upper side. There in the neighborhood of the iSight. What is this???? It sounds like a hard drive. Is the HD located near the camera? I need a silent computer because I record audio in front of it. That was the main reason I bought the MAC, three months ago, brand new out of the box.
After three months of software headaches (leopard) , the hardware troubles start too!! My Compaq Armada Pentium 3 laptop is still flawless after years and years of heavy use. I also ran Windows XP for more than 3 years without having to reformat. I have reinstalled Leopard 3 times in 3 months.
Whats going on with Apple?

Contact Apple and arrange for warranty repair.

IMac 5,1 20" external display options

I currently have a mini-DVI to HDMI adapter and a 20" 1080i TV, and they work albeit the screen is hardly legible in terms of type when I connect the two. I'm considering getting a 1080p monitor or TV to replace it to get the sharpness of progressive display and I want to make sure I get a wide screen ratio. I don't need colormatching. What 20" display/tvs have a VESA compliant back mount and HDMI and 1080p compatibility that won't be any harder to read than the display on my iMac 5,1 (the white Core2Duo).
Thank you.

Hi AB
While I can't speak for the Mini-DVI to HDMI and HD TV setup, I can say that I also experienced poor text quality and overscan issues with a previous TV setup.. For over a year now I've been using a 21.5" LG Flatron +(Mini-DVI to DVI)+ with my 17" 4,1 and it's a sweet setup. It really only took a little profile work, mostly on the 17" to get them near perfect. I use the LG as my main display for browsing, movies, photo editing and use the 17" for Finder windows, iTunes, Preference panels, etc.

Mac mini with a 24" display or a new iMac 24"?

Hi,
Since Apple releases the new iMac, and at the same time, updated the mini, I'm wandering where my heart should go.
I like the iMac, a little bit more powerful, better video card and not sharing memory with main memory, better BTO (bigger HD, faster HD too, memory, etc) iSight and mike, and so on so on. I have not seen one yet, but I'm still puzzled by the glossy screen. Many article I read said that it is a like or not based on personal taste and environment you put it in. I bought a Sony display 2-3 years ago, which I returned, because of the glossy screen. The images were very clean and very fun too work on, but I could not endure to see my face in the screen continuously. That's what I'm afraid about the new iMac.
So far so good, I read the article on http://www.macworld.com that compare the new mini C2D with an iMac, and while it is less performant it is still a good performer. Only a few points below the iMac. So...
Choosing a mini with a 24" of my choice with the same resolution as the iMac will cost me around the same (maybe a few hundred $ less), but I'll have a smaller/slower HD and not a dedicated video card. I'm wandering if the larger screen resolution will affect the mini performance? Sure, for the HD space, I can use an external HD on firewire. Maybe even boot from it and use the internal and slower disk for backups (like TimeMachine for instance).
I do not play game, or very occasionally, I'm doing iLife/iWork stuff, and Internet surfing. I want the larger screen, as I like to have spaces to play with, but I'm afraid the mini will suffer the higher resolution.
In the long run, the display will stay mine, when I ever decide to change my computer, while buying the iMac mean I'll drop the display and buy a new one. There's pros and cons to all of this...
So I'd like to heard from people having the new (or even older) mini to let me your impression of what you feel about this.
Thanks in advance.

If you are not able to actually examine an iMac carefully before you buy, the risk that the glossy screen may not suit you is a real issue which has to be considered. Imagine that you bought one and found it to have the same problem as the Sony display you tried and had to return?
Ultimately, the actual performance of the system is remarkably unimportant in most situations. The majority of users and uses would not show markedly different operability between a brand new Mac Pro and older G5, even though in terms of specification and benchmarking, the two are like chalk and cheese. The fact is that while the Mac Pro would be greatly faster, OS and software, not to mention the user him or herself, are all quite inefficient.
What that means is that the difference in performance between the iMac and the mini is certainly measurable, and in use would show itself in some ways (the iMac would run smoother for example) but without the ability to sit them side by side, as a user you'd really never know. Bearing in mind that the new minis are way faster than the old G5s which were themselves screamingly fast when they were in production (and still are), it's hard to imagine that a mini would fail to impress.
And since the actual performance of the system isn't all that crucial, what IS vital is to ensure that the system you buy is usable. The devices that matter most in that respect are the bits you, as the user, interface with. Keyboards and mice are reasonably cheap and easy to change, but displays are not when they are fixed and integral to the system.
The downside of the mini is twofold: Firstly that the internal drive is 5400rpm, thus relatively slow. In reality this really doesn't matter all that much, particularly not if you go for 2Gb RAM. It's been criticized for it's speed, but on the other hand, it's the same as the best laptops, users of which don't seem to have problems with the drive speed. It can be got around of course with a fast external drive, used to boot the system.
Secondly, the integrated graphics - not because that's really limiting in any absolute sense (except for gamers) but because as time goes by, more and more of the top-end software is likely to exclude systems with integrated graphics from their minimum specification list. There aren't many like that yet, and it's hardly likely to be a widespread problem, but it does mean you have to consider what software you want to run as part of the equation.
If I were in your situation, I'd not consider spending money until I had looked at the iMac and given myself some time to work with one. The fact it has a glossy screen doesn't mean it WILL have the same problem as the Sony display had, and slight changes in the ergonomics of your desk with the iMac on it rather than the system with the Sony display previously may mean that even if it did prove reflective, it may be far less of a problem (or more of course). I would look to buy the best system with the best specification that fit within my budget (after all, it has to meet your needs for some time, even as they change), thus if the iMac screen was good, that would be the system I'd go for. If there were any sense that the reflective properties of the screen were going to be a problem, I'd dismiss it as an option immediately, and focus on either the lowest cost Mac Pro if one of those were within the budget, and if not, a Mac mini with bumped up RAM and your choice of screen.

Screen Flicker and Glitch on 24" iMac, Early 2009

For a while now, my iMac has been having somewhat random display glitches, flickers, freezes, and kernel panics that can only be fixed by shutting down the computer.
Most of these screen glitches go like this: The display flickers black quickly, letting me know that an issue is going to arise. The issues that could happen are as follows:
A blue line glitch (very common)
a random artifact glitch (somewhat uncommon)
a freeze-up (very common)
a kernel panic
Let me describe these:
There are several types of "display glitches" I've been experiencing. Some of them involve random artifacts that are randomly displayed and seem to be hovering over whatever is going on on the screen–for example, once I was browsing Facebook and the glitch occurred, so a square of my browser screen was sort of cut out and stuck on the screen above everything else going on. The issue wasn't fixed until I restarted the computer. This glitch, however, wouldn't show up in screenshots. These are somewhat less common because it seems if this one happens then it either gets worse very fast and there are random pieces of my active windows all over the screen or it freezes the computer up entirely, or even results in a kernel panic.
Another "display glitch" that is far more common is a sort of line glitch. It's very strange: blue lines will outline random shapes and things all over the screen. Pictures on my browser appear distorted and videos look VERY weird. The dock has the lines and random blue pixels as well. The desktop background appears distorted. This glitch often starts with the screen flickering black and the various blue lines appearing. The lines change shape as the objects on the screen move around.The issue doesn't appear in screenshots but I documented it by taking crude videos and pictures on my phone that give examples.
Here's a link to my video of a video about a nonrelated screen glitch. I was actually searching Google for a solution but it turned out to be unhelpful, but since the screen glitch happened to be going on I decided to record it as an example. Notice how the blue lines move with the video...
Here are some pictures:
This next screenshot looks a little creepy with the armored polar bear–it's a LoL build on Mobafire. CLICK HERE TO SEE WHAT IT'S SUPPOSED TO LOOK LIKE:
---NOTE: My computer actually JUST screen glitched and froze up completely, at which point I had to shut it down and reboot. Luckily the post was saved! Just in case you were wondering how often these things occur.
This issue is getting worse and worse. I'm not sure what triggers it, but it seems like graphics-intensive programs like 3D games can trigger it–especially, it seems, when I toggle on and off fullscreen. It looks like it could be a graphics card issue, because if it was a software problem it would seem like it should show up in the screenshots. It's sort of an underwhelming graphics card, but meh. My mom is having a panic attack and backing up everything on the computer and we're thinking about just reinstalling OS X altogether.

Lion causes your system to use more resources so it will run hotter. If you haven't cleaned you iMac's dust out:
As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a

Problems with my new imac 27"

Hi! i got last day, the new imac and i have some little problems
1) I have a an usb 3.0 HD connected to a 3.0 hub. the hd isnt recognized from imac. i also tried to switch ports and disconnect other peripherals but the result its always the same. i resolved using an usb 2.0 cable but its not a deal considering first itme in my life i have a usb 3.0 pc and i cant use it. the same configuration worked without any problems on my old macbook, but in that case, it was usb 2.0. which can be the problem? too much bandwith? i also use a thunderbolt ssd as my primary drive. but i dont think thunderbolt and usb share same bandwith
2) i have connected the imac to a AV receiver for listening music and sometimes movies. with my old macbook i did that with optical cable for audio and hdmi for video but now i have both with one cable. problem is that if i duplicate monitors, the imac resolution switches to 1920x1080. only way is the extend desktop. in this way i have 2560x1440 on imac and 1920x1080 on tv, but its a pain in the *** when mouse pointer goes away to the secondary monitor (turned off, or unused). is there a way to enable ONLY audio hdmi, or to block secondary monitor?
3) i connected imac via lan but in that way my wifi (not airprint) printer isnt recognized, so i switched again to wi-fi. is there a way to use lan without problems?
thanks

1) not enough information to know what the problem is. Could be cable, could be hard drive enclosure, could be computer. check this article - going thru these troubleshooting steps may solve the problem if it is the computer.
2) I don't know
3) how is the printer connected to your network? Is there an unbroken line of Ethernet connections between the computer and the printer? If another computer is connected to that cable can it see the printer?

27: iMac Apple Mini DisplayPort to DVI adapter quits working post-firmware

I iMac Apple Mini DisplayPort to DVI adapter suddenly quit working after I installed Apple's latest iMac display firmware update. This is an Intel Core i5; the monitor is an LG Flatron 24" Wide, and when it powers up it says "no video input" and goes into power-saving mode. No amount of replugging cables helps, but the monitor works fine on other computers.
The Displays control panel just shows one monitor, and clicking Detect Displays does nothing.
I suspect Apple's Display Firmware Update. My installer log shows the following, but the problem only happened today after the latest update:
6/1/10 9:45 AM 27-inch iMac EFI Firmware Update 1.0
6/1/10 9:45 AM 27-inch iMac Display Update 1.0
6/4/10 11:47 AM 27-inch iMac SMC Firmware Update 1.0
6/4/10 11:47 AM 27-inch iMac Display Update 1.0
6/5/10 7:29 AM 27-inch iMac Display Update 1.0
I have automatic updates disabled, but after each update I would see more firmware updates ready, but caution leads me to never install more than one of these at a time, and then to wait a while to see if anything bad happens. The odd thing is that the Display Update 1.0 seems to have been installed three times in this course of events. Alas, there appears to be no way to uninstall a firmware update.

Since the adapter is an active device (it has powered electronics to convert DisplayPort signals to DVI signals) I suppose it could have just coincidentally died. But that seems unlikely given that the thing worked perfectly just before the last firmware update.
Does anybody have similar experience, or better yet, a fix?

Unfortunately the Apple Knowledge Base does not give much information about this update. Such has how to tell if it has been successfully installed. I suspect that because it keeps recurring in the install log that it has not been installed successfully as yet. Are you receiving this update through Software Update? Can you locate the installer for this update? It maybe located in Apps/Utilities.
Some firmware update installations can be interrupted/corrupted by attached devices. If you find the update's installer on your iMac, I suggest that you detach all external devices from the iMac, use an Apple USB keyboard & mouse if available, follow the instructions carefully and install the update manually. If you do not locate the installer I suggest downloading manually from the link below and installing it.
The Knowledge Base article mentions that your iMac should also have a Graphics Firmware Update. I suggest that you download and install that as well.

Considering dumping my iMac for a PC used for DSLR video editing on Premiere CS6. Help!

So I edit mostly 1080p DSLR footage taken from my canon T3i camera. I purchased a 2011 (the latest model) iMac a little over a year ago, upgraded the RAM to 12GB and it has worked reasonably well. I purchased the base model for $1200 which has a quad core i5 processor, 512mb of video ram, and a measly 500gb hard drive. The past couple of days I have come to the realization that I only use Adobe Programs for graphically intensive work (premiere, after effects, etc). I originally bought my iMac for final cut, but FCPX SUCKS and I switched to Premiere CS6 which works like a dream. Anyways, I'm a senior in high school and do lots of video editing (going to major in video production in college). I'm likely going to differ college for a year and continue my video production business (pretty informal) as well as video production internships at a couple companies (so don't suggest that I get a laptop for portability, not an issue). I just shot an entire wedding with 2 DSLR's and the footage takes up over 20% of my hard drive which is unacceptable. This is very troublesome for me and has been clogging up my computer considerably. I have realized it would make a lot of sense to sell my iMac and purchase a PC that's not only faster, but has much more space. I was ideally looking to sell my iMac for $1000, and from that get a better and faster PC setup for my video editing. $200 would be allocated for a 24" 1080p LED 5ms Asus monitor (from newegg) which would leave $800 remaining for the PC. Ideally it'd be nice to have a little cash left over. Some things that sound appealing to me are: an intel i7 quad core proccessor at least 3.0+ Ghz, 16 GB of ram (maybe 8 to start), 1 GB of video RAM (here is where I'm stuck, my Imac had a Radeon 512mb video card in it, but I've heard premiere runs especially well with nVidia CUDA cards? Don't really know too much about this stuff.) I have no idea what type of card to get, and if I would even see a performance upgrade from my iMac. For storage I'd like at least 2TB of space, should I get two seperate 1 TB drives? One for boot and software and another for video files? Anyways, I assume I can benefit from selling my 2011 i5 iMac to get a faster PC equivalent at a lower price since I mainly edit videos (which is pretty graphically intense) from an HD DSLR camera. I've noticed premiere rendering times on my mac are starting to get pretty slow these days. Ideally it'd be nice to buy a desktop (already assembled) maybe from HP for around $600 (not including the monitor). I'm not completely against building a PC from parts (since I know a friend who can do it for me) I just need help figuring out WHAT exactly it is that I need and would benefit from.

Mini-VGA to S-video resolution problems.

I have recently hooked up a Apple Video Adapter that connects from my 17" iMac 1.8 GHz G5 Mini-VGA port to the S-video port on my RCA TV. My problem is that while it is plugged in I cannot put my iMac resolution at the proper 1440 x 900 because the option is not there. In order to get the 1440 x 900 option back, I have to unplug the adapter. How can I fix this so I don't have to unplug the adapter?

Had the same problem here (drove me crazy) Search for ScreenSpanningDoctor. It will easily solve your problem.
