Ver El Capitan 10.11.6 - problems with external display

I've updated my Macbook Air to the latest version of El Capitan (ver.10.11.6), and since then, I had problems with my external monitor: image is thus largest, out of proportion, and I can't seem to be able to set the zoom out or by using the display options. That's all just terrible to work with her. It is not my monitor because I never change its configurations, and there is nobody else who has access, and the problem started after I updated to version 10.11.6

Any help will be appreciated!


How do you connect the monitor?

Mirroring your screen or to help us address display?

What is the native resolution of your screen?

  • Problems with the display of the 3D graph

    Hello world

    I use a 3-d chart in one of my screws and I have problems with the display. See what it shows by yourself:

    So, as you can see, the chart does not correctly display the data. But one thing I know, is that the data are sent correctly, because when I copy the LabVIEW graphic and paste it into paint, what I see, this is the graph displayed correctly:

    Anyone know what may cause the problem? I also have a similar problem with a waterfall in 3D.

    You can always download the updates of so.

    I also went through a documentation on known LV 2011 issues. I was able to find something interesting onthis page:

    3D image controls can display transparently or LabVIEW crash on some graphics cards

    The 3D Picture Control is based on an OpenSceneGraph that uses OpenGL. It was noted several reports of the 3D image control crashing LabVIEW. In almost all cases, it was an Intel graphics integrated into question. This accident is due to a mismatch of the graphic material. Note: most 3-d charts use the 3D picture control

    Some possible workarounds are:

    • Update the video driver
    • Enable/disable hardware acceleration
    • Enable Aero in Windows 7
    • Disable Aero in Windows 7

    I might try these workaround solutions and see if any of them work for you.

  • "A problem with the display driver.

    Recently, I get an error message whenever I open Photoshop CS4. It reads as follows.

    "As Photoshop has encountered a problem with the display driver and has temporarily disabled GPU enhancements. Visit the Web site of the manufacturer of the video card for the latest version of the software.

    "GPU improvements can be enabled in the Performance preferences panel."

    I checked the graphics cards in Device Manager, and when I tried to update the software, it told me that I was aware.

    Sincerely, Danny


    Try to update your display manually driver and do not use the analysis of the drivers on the manufacturer's website either.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system. For
    each driver in the list, additional useful information is displayed: load address of the driver, description,.
    version, product name, company that created the driver and more.

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - Device Manager - Display Adapter - note the brand and complete model of your
    video card - double - tab of the driver - write version information. Now click on UPdate Driver (this
    cannot do anything as MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
    This will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party with their
    own the software and drivers and all other main drivers that you have.

    Now go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restoration) and then of the manufacturer of the device
    (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for the BIOS, Chipset and software)
    updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after each installation.

    Always check in the Device Manager - tab drivers version you install actually shows up. This
    because some restore drivers before the most recent is installed (particularly that audio drivers) so install a
    pilot - reboot - check that it is installed and repeat if necessary.

    Repeat to the manufacturers - BTW on device at the DO NOT RUN THEIR SCANNER - manually check by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    How to install a device driver in Vista Device Manager

    If you update the drivers manually, then it's a good idea to disable the facilities of driver in the Windows updates,
    This leaves ONE of Windows updates, but it will not install the drivers who are generally older and cause
    questions. If updates offers a new driver and then hide it (right click on it) and then go look for new ones
    manually if you wish.

    Hi doriv,

    • Update your graphics card driver.
    • You have the graphical configuration Swichable?
    • As Mylenium says you must add this parameter in graphic control panel so that Photoshop can detect your card.

    Kind regards


  • I get the message: Photoshop has encountered a problem with the display driver and has temporarily disabled GPU enhancements. Visit the Web site of the manufacturer of the video card for the latest version of the software.

    Photoshop has been giving me the warning:

    Photoshop has encountered a problem with the display driver and has temporarily disabled GPU enhancements. Visit the Web site of the manufacturer of the video card for the latest version of the software.

    Also other programs are affected.  I suspect a recent download of Adobe.  Can anyone HELP.

    No, it has nothing to do with updates of Adobe. There is a problem with your video card driver.

    Go directly to the Web site of the manufacturer of the GPU for updates (not Microsoft, not a System Builder).

  • Problem with the display of Adobe PDF documents

    Problem with the display of Adobe PDF documents

    I have a Windows 7 Home Premium computer

    I read all the suggestions and I tried to download several versions of Adobe Reader for Windows 7 and Vista

    Before you download each version, I would delete the current version with uninstalling programs for the control panel.

    After each new installation I shut down the computer and restart the computer.

    I tried to download the versions with and without going through my antivirus (CA Total defense) running.

    After downloading, I thought that the version downloaded successfully.

    I have read the help of Acrobat and followed the instructions.

    None of the above helped.

    The problem is that any version of Adobe Reader, download, I can't open a PDF file and read it. Or the drive itself will remain open.

    1. If I try to open the drive from the desktop link or real program menu, the Player opens for 5 seconds and then closes spontaneously. If I try to click on the Player menu (File, Edit, View, window, help, tools), then an alarm will sound and the menu does not open. Soon after, the reader is closed.

    2. If I try to open the drive by double clicking on a PDF file then the Player opens but the document is not displayed (only the grey player screen PDF is specified), then the drive closes after 5 seconds on its own.

    The desktop shortcut shows like 'red icon Adobe Reader'. But the real program menu icon shows as empty a folder icon.  All documents in PDF format displayed as Adobe PDF icon.

    I tested several PDF files and none will open on this computer, but they will open on other computers.

    I created a word document and saved as a PDF file. It looked as if it had record properly (a the appropriate icon) but when I try to open it according to point 2 above the document is not displayed and then then the drive closes after 5 seconds on its own.

    Anyone have any ideas on what is happening and how can I fix?

    Could you please respond in this forum and send me an email at [deleted]

    I'm so confused and frustrated.

    I would try Windows Explorer, navigate to C:\Program Files (x 86) \Adobe\Reader 11.0\Reader, and then double-click Eula.exe and accept the license agreement

  • Problem with external HARD disk - cannot mount the mac partition and can't unmount the partition windows

    Hi all

    Need your help. I have problems with my external hard drive. I worked on it yesterday when the cable is a little detached and disassembled my intestinal HARD drive.

    Here are the specs:

    1 Macbook Air 11.5 "running on El Capitan (10.11.1)

    2 Buffalo Ministation external (1 TB) HARD disk divided into two: a Mac partition (for time machine) and the other a windows on FAT32 partition.

    Before the accident yesterday, it was working OK.

    Now, when I connect the HARD drive, it turns on but the Mac partition cannot be mounted (it does not appear on the Finder. I opened disk utility... just load forever and does not work) and the Windows partition is visible... but I can't take it apart without turning my computer.

    I can assemble and disassemble a USB stick very well.

    Any help would be appreciated.

    Thank you!

    Maybe you can explain a little better.

    I would like to make some general comments before having your replay.

    It is not wise to use TM on a disk with apple unformatted or partitions, it is preferable to have a dedicated TM drive also.

    For TM, the rule is that the drive is about 3 times the size of the boot disk.

    Normally you 'survive' a good step disassemble the drive external, but in this case with a another partition formatted on this subject, I'm not sure if that do not corrupt the disk, especially since the Windows partition is bootable. I have suspct the partition GUID on the TM partition table is corrupt.

    I propose to start the disk completely: in DiskUtility select the 'higher' level (name of manufacturer) and the Partition, one OS X Extended (journaled) partition table Partition GUID. And use it only for TM, is not too big for this.

    Have another drive formatted NTFS for Windows.

  • Problems with the Display Mode target on end 2009 27 "iMac

    Used late 2009 iMac 27 "in the view target in conjunction with a Dell XPS tower with i7 processor, Windows 7 and the best graphics card I could afford at the time connected by HDMI to mini display port cable.  Worked well for years.  Set aside Dell for a few months and the update of the iMac to El Capitan OS 10.11.3.  Recently tried old setup with same Dell PC and was able to move from Mac to PC, but the PC screen resolution was at the lowest setting. I got an error message when enabling/disabling to PC who said there was a problem with the port causing mini display of the system back to the lowest resolution. Impossible to reset at a higher resolution.

    I tested the Dell PC on another monitor, and it works very well at higher resolution (2560 X 1440). Now, when I reconnected it to the iMac (which works fine), the screen becomes black.

    Is it possible that the operating system upgraded (El Capitan) is not compatible with the targets using mini display port Display Mode?  Any ideas?

    Use your iMac as a display with the target - Apple Support Display Mode , also consider having a bad cable or connection. Does not hurt to try different cables, they can and will the bad!

  • Problem with external hard drive (an unexpected error - 50)

    I've had this problem for a few months now. Sometimes, I can't delete a file from my external hard drive, or export a file to it. The process is impossible, and I get a message "Cannot perform the action due to an unexpected error - 50". Ejecting the disc gives the message "eject impossible because another program can use it." Ejection force becomes the only option. After re-login, the problem goes away, like nothing ever happened.

    The question is not constant, but quite common to become a nuisance, the one I want stopped.

    That's what I think it is (a bad connection with the cable, defective contact), or is this a virus? I need to know.

    The hard drive is 1 TB Toshiba Canvio Basics and is formatted as Mac OS extended (Journalized).

    not a virus, and not only because there is no virus mac at this time.

    negative errors on the discs can be a signal indicating that the file is corrupted or worse still, the drive is failing. While it can also be a problem with the cable or the connector that it commonly goes back on the disc itself.

    Currently, it is recommended that you backup your data if a backup fails, you may need to save what you can manually and sometimes that means go to this folder by folder or file by file

    Use Time Machine to back up or restore your Mac - Apple Support

    All HARD drives (and SSD') eventually fail and while this isn't a your statement you should check the drive with disk utility (Macintosh HD/Applications/Utilities/Disk Utility) after you got what you possibly can off and consider replacing the disk with a new one.

  • I have a problem when using Google Maps, at a certain point my custards computer window and says there is a problem with the display drivers and he recovered, but it is not. Problem does not occur with Int Explorrer, so I don't think it's the computer

    When using google maps via Firefox, after asking a place which is not the General section of North America who comes up regularly, the firefox screen becomes white with a narrow banner at the top. A message appears in the lower right corner that says something on display drivers having had a problem, but now have been recovered. However, the display is not recover and the message of the banner is that Firefox is not responding. When I go to restart Firefox if I'm about to restore, the page is still frozen.
    I don't think there is a problem with my computer because it doesn't happen if I used to go to google maps, then G-cards works normally.
    This phenomenon didn't happen before the last update Google or Firefox. I used Fiefox for some years and also Google Maps on previous computers and on this one and not had it before.
    It is a relatively young computer (Asus EeSlate 121) less than a year. I have used Firefox since I bought it and until recently had no problem with Google Maps.

    I solved it myself, after the 'note' that was FF/Mozilla, just as I finished my message, commenting on what it was that my system was, I wnnt back to check my plug-ins, etc. I downloaded the latest Java, the TWO 32-bit AND 64-bit versions and latest Firefox.
    Now everything works.
    Thank you

  • Vista on Portege M200 - some problems with nVidia display driver


    I recently decided to update and perform a clean installation of Windows Vista on my Portege M200, now that Toshiba have released official drivers for this machine.

    Everything works fine, EXCEPT the nVidia display driver. I have the following questions with the driver Toshiba provides for this machine (97.52 version):

    (1) when the screen turns off to save power, the backlight does NOT turn off. Screen turns off but the backlight will stay lit.
    (2) for the recovery of the standby mode, the backlight is OFF. You must use the shortcuts Fn-F6/F7 to change the backlight level manually, that will bring him back.
    (3) external monitor does not work (with command Fn + F5 or nVidia control panel). External display is always blank.
    (3) video playback in WMP is very chopped (a secondary concern for me).

    Is there a chance that Toshiba could finally get a updated driver that would set out the? That would really make this machine fully functional in Vista.

    Thanks in advance for any help or information.

    Null value


    > Are there opportunities that Toshiba could finally get out an updated driver?
    I noticed that from time to time new updates of pilot (any series of notebook) are released on the European driver Toshiba page and, therefore, I m optimistic that new updates are available

    But note; usually, various problems can be resolved by installing some patches MS Vista and missing patches.
    Then visit this [MS update website |] and check if all the patches are installed.
