27" iMac Display Resolution

I would like to find out which display resolution settings are the default on my iMac 27". Can anyone help me here? I got them set wrong somehow, and can't seem to get them back to where they were before I screwed them up

Thanks so much babowa.
That's the size listed at the top of my list also, but it doesn't depict if it is default setting or not.I'll use it for a while and see if it seems the same. I appreciate your response and help a lot.

Windows 7 display resolution problem on iMac 27"

Hi, I have an iMac 27" that is running bootcamp with Windows 7. The resolution on the OS X is fine, but on the Windows 7 side, it is messed up. The display resolution choices make the screen look all stretched and weird; I cannot select the same resolution as I have on the OSX side. The display drivers say that they are generic, so I tried installing manufactuer's drivers. That did not work since they couldn't detect the correct monitor. I've run software update on he Mac OSX side, but to no avail. Does anyone know how to fix this? Thanks!

updates for osx will not affect windows
in osx one can make a packet with all drivers required for bootcamp windows do that
and if you need drivers for windows download the mobile version what amd/ati and nvidia call desktop videocards
are not the type used in imacs they use the laptop versions

IMac 24' Display Resolutions

I'm having an issue with my iMac 24' specifically with display resolutions. I have the 24' Penryn 2.8Ghz iMac with the ATI 2600 Pro video card.
The iMac is supposed to support the resolution 1680x1050. How do I know this? I had another iMac, the exact same model which supported this resolution. It was available in the Display preference pane on the previous iMac, but is not listed on this iMac. Apple also states in it's support documentation that 1680x1050 is indeed a supported resolution.
I've done everything to try to get this resolution working, I've reinstalled the OS, reset the PRAM and still no 1680x1050. At this point, I don't think the issue is software related but that is entirely guessing on my part.
As far as I can tell, this issue does not seem to be occuring solely on my iMac as I have checked several others and the resolution is not listed in System Preferences but I find this extremely as the previous iMac I had did have this resolutions.
I'm wondering if anyone else if having this problem or if they have 1680x1050 listed in System Preferences.
BTW, two highest resolutions I have listed are 1344x840 and 1920x1200.
Any help would be greatly appreciated.

Imac display problem, the resolution seems to be unusual, top bar and all folders on the desktop background is off the screen

Need help with 21" imac display problem. The resolution seems to be unsual, everything on the desktop background goes off the screen. The resolution is set at 1920 x 1080

Quit the game and restart the iPad.
To quit the game - Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
If that doesn't work try this.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

24" Imac only showing 2 display resolution options

Within the past week something changed after running a Mac software update that resulted in only having 2 display resolution options. The display choices now are limited to 1900 X 1200 and 960 X 600. I think this happened after having a Mac software update. I don't know what the updates were other then they were suggested as part of the automatic software updates check.
Running OS X Lion version 10.7.4.
Graphics = NVIDIA GeForce 7300 GT 128 MB.
I have rebooted and checked for additional updates put still only seeing 2 choices.
Is anyone else having this problem or ideas why all the other resolution options disappeared?
Thanks

Thanks for quick response. I looked as suggested but those listed are older issues and not recent new events. I guess I will sit back and see if there is a new update coming that fixes issue. Really madding not being able to re-set resolution to one that I have been using for years.
If anyone else knows background/input on why resolution options would go from at least if not more then 10 to now only having 2 would be great.
Thanks again.

Display resolution and Mac OS X 10.5.7

I am now using my Mac mini (early 2009) as my primary computer (new aluminum keyboard and an LG 23" LCD HDTV) and have sent the iMac Core Duo to "the boys" room for them to use. But they have called my attention to the display resolution a few times since I updated it to 10.5.7. The iMac seems to be lost as to what its default resolution should be. It was always set 1024x768, but that appears really tiny onscreen.
I also have noticed a large number of folks in the Mac mini (early 2009) forums complaing that after the update, they have lost the native resolutions they previously used with the mini and HDTVs when setup as a media center.
Has anyone here noticed resolution issues following updating to 10.5.7? Have you found a way to correct the issue?

Hi David
No problems here with the 10.5.7 update, the resolution on my 17" is and always has been set to 1440x900 Millions both before and after the update. +(1440x900 is the native res. for a 17" display)+
If I switch the iMac Display to 1024x768 Millions it makes everything larger and slightly blurred, again the same before and after the update.
Also note that the settings for my connect 27" Sharp flat screen TV are 1024x768 60Hz (NTSC) Millions was not affected in anyway. I always run my setup in Extended Desktop, but if I switch to Mirroring then both the iMac and TV Displays go to 1024x768.
Sound to me like it has something to do with selecting the Mirroring/(Extended Desktop)Mirroring Off feature...?

Display resolution for 2014 MBP?

How do you adjust the display resolution to the "native" 2880 x 1800 on a mid 2014, 15 inch rMBP with NVIDIA Graphics?
I can not obtain a resolution above 1920 x1200.

Hello there, pf2555.
When adjusting resolution for your MacBook Pro Retina, the following Knowledge Base article offers some information on that regard:
Frequently asked questions about using a Retina display - Apple Support
How do I adjust the resolution of my Retina display?
MacBook Pro (Retina, 13-inch, Late 2012 and later) displays have a 2560-by-1600 native resolution at 227 pixels per inch with support for millions of colors.
MacBook Pro (Retina, Mid 2012) and MacBook Pro (Retina, 15-inch, Early 2013 and later) displays have a 2880-by-1800 native resolution at 220 pixels per inch with support for millions of colors.
iMac (Retina 5K, 27-inch, Late 2014) displays have a 5120-by-2880 native resolution with support for millions of colors.
If you need to adjust the display resolution, choose System Preferences from the Apple () menu. The Retina display offers scaled resolutions that allow you to have text and objects appear larger on screen, or to make them appear smaller which provides more space on screen. Note: Scaled resolutions do not offer the same visual quality as the Retina setting. Scaled resolutions may also impact graphics performance depending on which applications you are using.
MacBook Pro with Retina display (13-inch) scaled resolution choices
MacBook Pro with Retina display (15-inch) scaled resolution choices
iMac (Retina 5k, 27-inch, Late 2014) scaled resolution choices
Retina displays only use scaled resolutions rather than specific resolution settings like external displays. If you need to use a different resolution than those available on the built-in display, consider attaching an external display via HDMI or Thunderbolt.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

Can I use iMac display as an external monitor with a pc?

I have a Windows laptop with VGA output. Can I connect this laptop's VGA output to mini display port of my 27" iMac?

This can't be done. VGA is an audio signal and there are no converters to turn it into a digital Display Port (DP) or Mini Display Port (MDP) signal. DVI and HDMI are digital signals (with HDMI having audio and a different physical connector) that can be converted into an MDP signal, but doing so requires an expensive converter or an even more expensive converter and scaler if you want to get full resolution on the target display. The cheaper but perhaps more complicated alternative is to replace your PC video card with a DP/MDP card after which you should be able to drive the 27" iMac display without any converter. Apple didn't include DVI/HDMI input capability in the 27" iMac because that would have required additional circuitry that would have raised the price substantially.

Is the 27" iMac display exactly the same as the 27" ACD?

I'm looking at updating my existing set up and want to know whether the above displays are exactly the same. From memory the ACD's were usually of a better quality compared to the iMac displays. Have they achieved parity now? Where will I find full specifications as I can't find them for the iMac - only that they are ips displays, and the resolution and speaker wattage.
Thanks guys.

Read the specifications on each (available on Apple's site) and you will have all the information you need.

MBA - Video display & resolution concerns

Hello!
My parents currently own an aging, first-generation white MacBook. I want to help them migrate to a newer laptop, possibly a MacBook Air aka MBA), within the next several months.
I used to own a 15-inch MacBook Pro (2007 vintage, IIRC) but it died on me in March. I was forced to buy a refurbished late-2012 iMac because money was too tight to procure a new laptop. I may also be looking at an MBA within a year, possibly an 11-incher.
I have a few questions about the video display resolution of late-model MBAs:
According to Apple's "tech specs" page for the MBA, the 11-inch is capable of multiple video resolutions:
1366 by 768 (native), 1344 by 756, and 1280 by 720 pixels at 16:9 aspect ratio; 1152 by 720 and 1024 by 640 pixels at 16:10 aspect ratio; 1024 by 768 and 800 by 600 pixels at 4:3 aspect ratio
I am a little concerned that a laptop display of that size would be a bit hard to read at the standard resolution of 1,366 x 768 pixels. Has anyone dialed the MBA's resolution back to lesser levels, like 1,280 x 720? Does anyone leave it at these lower resolutions? Also: how hard is it to use word processors or iPhoto on an MBA, particularly the 11-incher?

My parents...possibly an 11-incher.
Not to say your folks are old at all,... however Im likely much younger than them and having owned an 11" and now a 13",.... I cant go back to the 11" (though I loved it fine and sill can use it just fine)
Very likely their eyeballs would be more happy with a 13"
base model price on a 13" vs. an 11" isnt that much

How do I download more display resolutions (scaled)?

Hi,
I am displaying my iMac through a VGA adapter to a projector.
Under system preferences, displays, resolutions (scaled) - I have only:
- 1920 x 1080
- 1600 x 900
- 1280 x 720
However would like (and have seen on my macbook) far more options. How do I get more options?
Thanks,
David.

Logic, UI, and display resolution

One of the reasons I was eyeing the iMac was because it came with such a great display built into the price. I find the 15.4'' screen on my Macbook Pro to be rather limiting, and since OSX is resolution dependent, I cant really get around it.
I ended up deciding to skip the iMac for an 8 core Mac Pro which will last longer (even though the iMac currently outperforms it in logic lololol).
Turns out that it is pretty much impossible to find a screen with resolution above 1920x1080 unless it costs around $1000, which I cant afford to spend on a display.
I'm wondering if any of you have come up with solutions. Is there a way to adjust the UI in Logic so that having a bigger screen (regardless of resolution) would still be helpful, or is it that I may as well go with 21.5'' displays?

Ah, so you got it at Fry's eh? Are you by chance located in a western state with water on one side, Nevada on the other, and a few other states piled on top?
Also, are you using any kind of FW or PCIe-based video card with that?
Yes, CA.
I am using the video card that came with the Power Mac tower. It's a dual output one. Even though it is only 1920 x 1080 resolution, darn those are some BIG pixels, and it looks very good. My eyesight is not what it used to be... so every bit helps.

Can't read iMac display

My imac display is unreadable. Everything looks pixelated and blurry with the resolution set to 1680X1050. It has the Radeon X1600. Tried font smoothing and changing the resolution but it didn't work. Also hooked up a second monitor and the image looked perfect on that one. When you zoom in on the imac its readable, but still does not look up to par. Any help would be greatly appreciated.

HI and Welcome to Apple Discussions...
Try Resetting the PRAM
If that doesn't make a difference, might be a good idea to run the Apple Hardware Test

24" Alum iMac screen resolutions

Is there any way to change the screen resolution to 1600x1000 on the new 24" imacs? There are several other options on the display preferences but not this one. Anything other than the native is too fuzzy and the native 1920x1200 makes everything on the screen to way small to see from a safe distance..and I do wear glasses! It does put a lot of strain in my eyes.I know I can increase the size of the icons and text, but the Adobe pallets and other content is just too small. It shows up on my 23" cinema display with Mac Pro.

I know it is not crystal clear as native, but it does not look bad at all on my 23" cinema display. Why can't I set my imac to this resolution?
It's more than likely (I could be wrong) monitor based?
Let's use windows for an example. I have 2 monitors, both supporting different resolutions, the graphics card supports dozens of combinations but monitor 1 only supports certain ones, and monitor 2 only supports certain ones.
I plug in monitor 1 on my windows pc (using windows as an example) and I can set to all these widescreen resolutions. I plug in monitor 2 and the only resolutions I get are some widescreen and most of them non-widescreen.
The iMac display may only support certain types which is being detected by the OS and those are the only given options you have.
The cinema display is recognized as supporting other resolutions and thus THOSE are displayed as options.

Is it possible to turn off imac display while mirrored display plays video?

I've set up a new 21.5" imac for my parents use in their living room and have connected their 52" lcd tv to the imac as a mirrored display.
One issue that i can't find a solution to is to find a way to turn OFF the imac display when they're watching content on the lcd tv. If they want to watch a film from the imac out to the LCD TV, they want to dim the lights and watch it, but the imac display being on in the dark room is distracting.
Is their any way (3rd party software??) to turn off the imac display while still being able to have the mirrored display running?

You should actually NOT use mirroring, although it would work OK on the 21.5-inch iMac because the screen resolution is identical to 1080p HDTV.
In System Preferences Displays pane Arrangement tab, turn mirroring OFF. This makes the HDTV screen extend the iMac's Desktop. In the diagram on that pane, it shows how the two screen arranged. The edge where they touch is where you can move your mouse cursor from one screen to the other. You can move the two screen around in the diagram, to match how the iMac and HDTV are located in the real world.
In System Preferences Displays pane Display tab, there will be a window for each screen. The 21.5-inch iMac's screen should be set to 1920x1080. The HDTV's screen should be set to 1920x1080 also, if it is a "1080p" HDTV.
To watch video content on the HDTV, first show the video playing in a window. Drag the window to the HDTV screen so that it is completely on that screen. Give the full screen command (usually Command-F). The video will play in full screen mode on the HDTV screen. In most video playing applications, such as DVD Player, QuickTime Player, iTunes, etc., the other screen (the iMac's screen in this case) will go black. It's not OFF, but it will display black.
Note: Some video playing apps have a preference setting for which screen gets the full screen. When playing video content in a browser window (such as YouTube or Hulu), when you go to full screen mode by clicking the +full screen+ button, the other screen will not go black.
As far as I know, there is no way to turn off the iMac display, even with mirroring turned OFF.
