30'' Display Resolution Misbehaving

I have a 30" Apple cinema display. I just unhooked everything (which was working fine) and set it up in my new house. The icons are HUGE, the fonts HUGE, etc. I have the preferences set to the highest resolution, I've checked universal access and magnification is turned off, and I trashed the preferences per some advice I found in here and rebooted to no avail. So, what am I missing?

The 30" needs a dual-link DVI port for full resolution. Some Mac Pro graphics cards have one single-link and one dual-link DVI port. Try the other connector on the graphics board.

  • How to change external display resolution WITHOUT clicking "CONFIRM"?

    I have a somewhat unusual situation. My MacBook laptop is actually now a ModBook (a pen-tablet computer), and as such I no longer have a trackpad attached to it. All of my inputs are via the stylus, tapping directly on the built-in display.
    This works perfectly fine, except when I need to give presentations on an LCD projector (which is quite often lately). I like to use the projector as an external monitor, so that I can run the Keynote presentation on it while using my laptop screen as the presenter's display, with the upcoming slide, etc. If the projector doesn't give me an ideal native display option (sometimes, the aspect ratio for the  3 or 4 resolutions available in the Displays drop-down in the menubar turn out to be stretched or squeezed), then I, naturally, have to open the Display System Preferences and try out different resolutions.
    The problem is, since my stylus only interacts by clicking directly on the built-in-display, I have no way of moving the cursor over to the external display when the dialog box with the "Click here to confirm change/You have 15 seconds..." message appears. So I can never click it ... so I can never confirm the new settings.
    The workarounds I've used so far are:
    - Mirror displays (not ideal, as I need the presenter preview of the next slide)
    - borrow a mouse from someone (usually from a Windows desktop, frankly) and plug that in to briefly mouse over and click the confirm button
    I'd love to find a software workaround that allows me to NOT mirror displays and also doesn't require me to carry around a mouse all the time (my laptop bag is already overstuffed...).
    Thanks.

  • Thinkpad Yoga - Insufficient external display resolution over the Onelink

    My local Lenovo Partner just confirmed the data in "User Guide" of the TPYoga, that the external screen resolution will only be 1920x1200.  
    "User Guide"  Page 10, http://www.lenovo.com/shop/americas/content/user_guides/tpyoga_ug_en.pdf
    "Display resolution:
    – LCD: 1366-by-768 or 1920-by-1080, depending on the model
    – External monitor: up to 1920-by-1200, depending on the monitor model"
    I mean what do I want the OneLink Dock / OneLink PRO Dock for??
    Of cause to connect a large screen and this not with a worse ppi than the intern display. So I need at least 2560x1600
     (we don’t even talk about all the disadvantages of a 16:9 screen, cause that’s off topic).
    Idealy I expect of cause a 4k resolution possibility together with the OneLink Pro Dock and multi stream (daisy chain) possibility at the display port.
    But 1920x1200 external graphic output can’t be meant serious for a 2000US$ device?? 

    Ok, let’s accept that the new Thinkpad YOGA Manual includes misinformation.
    Actually I’m sitting in front of my 2048x1152 Display which is connected to my 8 years old Asus Notebook via DVI. Does this old jalopy perform a higher resolution via DVI than the Thinkpad Yoga via “OneLink PRO Dock-DVI” does? 
    http://download.lenovo.com/ibmdl/pub/pc/pccbbs/options/tp_onelink_pro_dock_ug_en.pdf
    Page 13
    (I’m guessing in the first line (behind "One monitor") it’s supposed to mean DVI instead of DP”
    (1) Lenovo, are these technical details of the NEW OneLink Pro Dock also wrong like the Manual of the Yoga regarding the maximum resolution?
    Would be very helpful for me to plan with correct information..
    (2) And is it definitely true that I can't connect two displays at the OneLink PRO Dock with a higher resolution than 1920x1200??
    That would mean I send the Thinkpad Yoga back and better stay with my 8 years old ASUS jalopy.. smileyfrustrated:

  • Leopard "Forgets" External Display Resolution

    I have a 17" MacBook Pro C2D (Oct 2006 revision) that I use at work with an external display (Dell E197FP) that is connected to the laptop via the DVI-to-VGA adaptor. The Dell has a native display resolution of 1280*1024 @60Hz and this is set via the System Preference's Display panel. The problem is that quite often when I connect the display in the morning OS X (10.5.6, at present) "forgets" the resolution that has been set and reverts back to its default for the display, which is 1152*864 @75Hz. It is baffling to me that it keeps forgetting the selected resolution for the display, despite recognising it, and that it selects such an odd resolution as a default. This happens about once per week at the moment.
    Does anyone have an idea what is causing this and how I can stop OS X from being so forgetful?

    Are you getting one to extend your desktop? I don't, I use my MacBook with the screen off using my external only with a keyboard and mouse plugged in. I run my Late 2008 2.1GHz MacBook with a GMA X3100 using a 23" Samsung wide ratio no problem in 1680x1050. It is high resolution. Make sure you click "mirror" in Display Prefs. Be certain that you don't simply boot to both because the external will appear grainy and only be putting out the native 1280 X 800 13" MacBook resolution on the new big LCD. There are many different ways to achieve this. With the LCD on and hooked to the MacBook, turn the MacBook on then quickly close lid after the chime. Give it some time. After it boots to the external, I open the lid to provide proper airflow, some may argue it's not needed.

  • External display resolution

    I have Dell up2414q monitor which is capable of displaying up to 3840 x 2160. But when I connect my 11-inch Macbook Air (the latest 2014 model), which is capable of 2560 x 1600, shows only 1920 x 1080. This is the highest resolution listed in display setting.
    I'm using Display Port cable and enabled Display Port 1.2 setting on the monitor. I went to Apple Store and asked, but they had no idea what was wrong. My OS is 10.9.3.

  • External Display resolution problem after resetting PRAM

    Gello, I've got Fujitsu-Siemens P19-2 monitor hooked up to my MbookPro and after resetting PRAM the correct display resolution disappeared from the "Displays" menu in System PReferences.
    So did the refresh rate option...
    What do I do?
    I really need to change the refresh rate and the resolution, but the refresh rate button is grey and unclickable, and the resolution simply isn't there (I need 1280x1024).
    REsetting PRAM and SMC didn't help.

    After a couple of resets everything went back to normal

  • External display resolution changes after returning from display sleep

    I often use an external display as a second screen with my Macbook Pro (OS X 10.8.2)  However, when I return to the computer after the display has gone to sleep, the external display resolution changes when the display reappears.  Then I have to go into System Preferences > Display and "Detect Displays" in order to return the external display to the proper resolution.
    Does anybody know of a way for me to avoid having to do this every time my display sleeps?
    Thank you,
    Adam

    I have the exact same problem.
    I found the key combination ⌘ alt F2 also restores the proper resolution on both displays, however it's still a bit annoying

    According to the copy&paste from wikipedia, HDMI should support higher resolution than 1920x1200. So the question is, does it aupport that on the mid 2011 mac mini. It says in the specifications
    "Mac mini is designed to work with HDMI devices that comply with versions 1.0, 1.1, 1.2, 1.2a, 1.3, 1.3a, and 1.4 of the HDMI specification."
    That should mean it should be able to support it, but I don't know : <

  • Cannot  set display resolution after upgrading to Mavericks

    I have early Mac Mini  connected to KVM stitch.  Over the weekend I upgraded to Mavericks and it "dowgraded" display resolution from 1920x1200 to 1600x1200 and everythign looks streached.  1920x1200  no longer shows on the list in display properties (1920x1440 shows but it does not look good on my screen). I googled Option key trick and hitting "Scaled" while hold Option key does show some additional resolutions, but not the one I used to have. 
    Connecting Mac directly to the monitor allowed me to set proper resolution and after removing monitor and pluging mac back into KVM things "held" untill Mac goes to sleep or until reboots.
    I am aware that my KVM switch does not communicate EDID but things did work just fine before upgrade to Mavericks.

    Hello curtdav,
    It sounds like you are getting a graphical anomoly when unplugging an external monitor. I recommend these troubleshooting steps from the article named:
    Apple computers: Troubleshooting issues with video on internal or external displays
    http://support.apple.com/kb/ht1573
    Reset the system
    You can reset the Mac's parameter RAM and SMC.
    Reset the resolution
    Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
    Start up in Safe Mode.
    From the Apple () menu, choose System Preferences.
    Choose Displays from the View menu to open the preferences pane.
    Select any resolution and refresh rate that your display supports.
    Restart your computer.
    Thank you for using Apple Support Communities.
    Take care,
    Sterling

  • I am unable to play a downloaded HD movie from iTunes. SD movies play OK. An error popped up saying something about the display not suitable for HD movies but now all I get is a blank window. I have tried changing the display resolution to no avail.

    I have sownloaded an HD movie from iTunes store and when I attempted to play it on my Windows 7 PC a error message popped up saying something about the display not being compatible for HD movies. I have tried changing the display resolution several times but it didn't help. Now it just comes up with a blank screen when I attempt to play it. SD movies work fine. I have the latest version of iTunes installed.
    Can anyone help me resolve this problem?

    Apparently the display is required to be HDCP compatible to view HD movies in iTunes. My display isn't so this is my problem. I contacted Apple support and they have agreed to credit me for the HD movie and I have now downloaded the SD version.

  • I just bought a new PC and I have re-installed my Adobe Creative Suite Standard on it. Software open fine. PROBLEM: The toolbars (menu stuff) appear extra-small, too small for me to read... I sent on the PC setting to try to change the display resolution.

    I just bought a new PC and I have re-installed my Adobe Creative Suite Standard on it.
    Software open fine. PROBLEM: The toolbars (menu stuff) appear extra-small, too small for me to read...
    I went into the PC settings and tried to change the display resolution. This changes the size of all  the icons (not only Adobe) but it does not solve the problem when I open an Adobe application (Photoshop or Illustrator)... The PC is run under Windows 8.1 and my display resolution is 3200x1800 (but again, when I change the settings for a smaller resolution, only the size of the icons is affected. Once I open the software, the problem is still there, extra-small toolbars...). Help!!!

    Anything before CC is not high-DPI compatible. Feel free to continue to experiment with your system settings.

  • 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

  • Cannot change display resolution when connected to external display

    On my 2.0GHz 13" MacBook, I have no problem with the display resolution when connecting to external display/projector when I am running in Mac OS, everything work perfectly! But things start to get messy when I am running in Windows VISTA 32 (installed within the Boot Camp 2.1). Whenever I connect to any external display/projector via a MiniDisplay-to-VGA cable, the resolutions on both my MacBook LCD and external display/projector drop to 640x480. And i am not able increase the resolution in the Display Settings. Does this mean that I have not installed the latest version of display drivers? Or is it that Apple did not provide the VISTA 32 drivers (in Boot Camp 2.1) that is compatible with the Mini Display port.

    Cool!
    I'm glad you have it fixed.

  • How do I adjust display resolution for Mac Mini?

    How do I adjust display resolution for Mac Mini? Text does not look crisp.  Using Samsung 27 inch monitor with HDMI input

    Apple menu -> System Preferences -> Displays. Depending on your version of Mac OS X, it may be set for "Best for Display" in which case it should already be set at the optimum for your monitor, or it may display resolution options in which case you should set it for the native resolution of your display.

  • Display Resolution and iPhoto (MBA, Mavericks, iPhoto 9.5.1, etc.)

    I get an error message saying the resolution is not optimal for iPhoto when I select the bottom option (1024 x 640), but the other two options are so small as to be a strain on the eyes.  The bottom control bar is not accessible at that resolution, unless I hit the full screen arrows at the top right.
    The "Best for Display" resolution setting is even worse than scaling.  Fairly puzzled what to do.
    Thanks,
    Steve

    Thanks for the response, but it seems unlikely, since my last computer, a 2006 Powerbook G4, had great iPhoto resolution when the display was set at 1024 x 768.
    Any other ideas?
