What preference controls Screen Size and Resolution

After many months of good behavior, my MacBook Pro is back mirroring video to a phantom VGA monitor every time I wake it up. This mangles the view of my actual laptop screen since the phantom is 800x600. I can get rid of it by clicking Detect Montiors, but it takes between 10 and 20 tries for this to work. I am presuming that a particular preference file controls this behavior, so perhaps if I trash that pref, things will go back to behaving normally. I could not find a pref file for displays. Any ideas?

Resetting PRAM and NVRAM has no effect on this problem. Removing the com.apple.systempreferences.plist seems to have done it. The problem is somewhat intermittent, so I will report back in a week if it looks like it solved the problem completely.

  • What Preferences Control Window Size and Location?

    I have a number of windows that over time have taken on weird sizes and locations. For example, a print window habitually shows up with the print button underneath the dock, forcing me to move the window to click on the options.
    Is there a preference I can trash--or anything else I can do--to return the sizes and locations of windows to something resembling normal?

    That's done by each individual application.
    Many will remember where the window last was, and re-open it in the same place & size.
    Find the preference file for the app in question (probably in <your home folder>/Library/Preferences folder), quit the app, rename the file (append "old") to the end, and start the app again.
    The window should open in a default location; move/and or resize it, close the app and open it again. If that fixes the problem, trash the "old" file and re-enter any other preferences.
    If it doesn't fix it, you've probably got the wrong file. Close the app. If there's a new version of the file you renamed, delete it. Remove the "old" from the previous one.

  • Screen Size and Resolution on Remote Access Mavericks

    Hi Forum,
    Accessing my Mac Mini remotely and it has a new install of Mavericks. The Screen size and shape and resolution isn't right, but Screen options in System doesn't give me any options. Is this because, physically, no screen is attached? Do only screen sizes and options come up when a screen is attached?
    it currently shows 1280x960 [i think - just turned off the mac to get back to work] or 'scaled to fit'. Neither is right for the MBP remote access,. It was fine before i upgraded.
    any ideas?

    Hi xerhino, and a warm welcome to the forums!
    Good work on your part!
    Hope your doing OK with the Snow, Ice, and Winds!

  • What is the ideal size and resolution of a photo for display on the iPad?

    I'm finding no info on the size of a photo for the best possible display on the iPad.  The screen is obviously much larger than iPod Touch or iPhone; photos sized for them are fuzzy on the iPad.  Ideally, a photo should be sized for the exact number of pixels on the iPad screen.  Can anyone help me here?  Thanks!

    This is done automatically via the iTunes sync/transfer process - photos are optimized for viewing on the iPad, and there is not an option to change the default optimization settings.

  • Screen size and resolution mismatch after 2008-008 update.

    This is very odd. My screen is shifting around every time I move the mouse on my macbook pro. It appears that the mac doesn't think the full resolution will fit on the screen, and so shifts a few pixels up (or down, left, right) whenever I move around the screen. It's very difficult to use since it distorts whatever I'm reading. I've tried selecting different display resolutions: 1440x900, 1280x800, & 1024x768, but the problem persists even on lower resolutions.
    Could be a red herring, but I've checked the install.log for errors and found a couple instances of this sequence:
    Dec 22 07:42:04 gseven : update_prebinding[25268]: update_prebinding: too many errors (101)
    Dec 22 07:42:04 gseven : update_prebinding[25268]: update_prebinding: error: terminating
    Dec 22 07:42:04 gseven : update_prebinding[25268]: update_prebinding: error 256 running updateprebindingcore
    I don't know if that could even be related. Anyway, does anyone have an idea how to fix this?

  • Window & frame screen size and resolution

    hi,
    i have just finished my website:
    - done with dreamweaver mx and mac
    - only html with a menu on the left frame that always stays
    the same and pictures on the main/right frame
    - haven´t had any trouble opening the website with
    safare or internet explorer in my computer.
    the problem seems to be that in some PCs, the left menu
    doesn´t appear completely, the last 4 lines from the bottom
    disappear under the screen and you need to scroll down, which is
    not how it´s meant to work.
    this might be a silly thing to ask for it´s simplicity
    but i can´t seem to make it work. can someone offer some help?
    thanks!!

    Don't use frames.
    The reason for using or not using frames should be based on
    a) your site's
    needs, and b) your willingness to accept the potential
    problems that frames
    can create for you as developer and maintainer of the site
    and for your
    visitors as casual users of the site.
    I am down on frames because I believe that they create many
    more problems
    than they solve.
    Judging from the posts here, and the kinds of problems that
    are described,
    the kind of person most likely to elect to use frames is also
    the kind of
    person most likely ill-prepared fo solve the ensuing problems
    when they
    arise. If you feel a) that you understand the problems and b)
    that you are
    prepared to handle them when they occur, and c) that you have
    a need to use
    frames, then by all means use them.
    As far as I know, the most comprehensive discussions of
    frames and their
    potential problems can be found on these two links -

  • Adjust the screen display dynamically for a given screen size and resolutio

    Hi All,
    Is there a posibility to change the size of a table control dynamically to maximize the screen utilization keeping in mind , the different screen size and resolution. This is to increase the breadth of the table control that there is maximum utilization of screen and which would not produce any horizontal scroll bar in case of small size monitors.Kindly advice.
    Best Regards,
    Ashwini

    There is no such control that you can put into the programming logic to enhance the visual appearance of the table controls or screens. This is taken care of by SAP GUI, which will adjust the display size of the table control according to the screen resolution.

  • Best Size and Resolution to Scan Photos?

    Hi, I need to create a photo slide show in iMovie. I would do it iPhoto but I need to able to time my music and add intermittent titles so I guess I'll need to use iMovie. I'm very new to iMovie and actually am used to editing on Avid and Media 100 (which I no longer have access to) so I'm a little scared! So, my question is - when I scan my photos what is the best size and resolution to scan them at for the best final results? It will be viewed on a TV from a DVD. Any other tips for a newbie also appreciated. Thanks so much! -Julie
    p.s. I'm using iMovie HD but I'm on a G4 so don't have HD capabilites. Not sure if that matters.

    Hi Julie: Look here:

    That should help.

    No, that doesn't matter at all.

  • What is the best actual size and resolution to save photos to put on your iPhone?

    What is the best actual size and resolution to save photos to be easily viewed on IPhone?

    Sorry, this is my first use of this support site.  I didn't realize that it was only for technical questions.  I am not the one who loses his iPhone, but I just wanted to provide some help to our family member who does.  He is usually a very responsible person, but he has lost his phone more than once.

  • How do you change the image size and resolution in photoshop everytime I change the width the height changes my measurements will not stay

    Can someone assist me with changing image size and resolution.  each time I change the width the height changes and vice/versa?

    There's a chain link between width and height. The point is to keep the aspect ratio the same, otherwise your picture would get stretched.
    You click on the chain-link to shut that off and you can adjust width and height separately.
    Also could you give us your version of Photoshop, what OS you are running it on (Windows 7 for example) and what exactly you want to do with your document?
    Resolution is the print term for how many pixels will be printed on an inch of paper. It doesn't apply if your image is intended for screen viewing.

  • Image Sizes and Resolution standards?

    are there any standards for image sizes and resolution for mobile games specifically: backgrounds and backdrops?
    i will be porting my game for various cell phones and i'd like to resize images to fit perfect on all cell phone screens, so what would be the best way to do this and what should my image attributes (height, width) be?
    i've tried researching on google to see if there were any standards and couldn't seem to find any. if these standards are non-existent what image sizes have you used that you found worked best on various mobile phones?
    thanks
    Edited by: sassy on Jun 2, 2008 1:49 PM

    Google's right, there are no real standards for screen sizes. Some are more common than others, but there are dozens of common screen sizes.
    The most common are...
    176x208 (same as 176x220, but with no status bar)
    240x320
    176x220
    [Getjar resolution stats|http://www.mobref.com/statistics/world/gDispResolution]
    Unfortunately, many phones are slightly more or slightly less than those. If you cover those, you're fairly well off though. If you can make your game resolution independent, that's your best option, though with intricate overlays it may be nearly impossible to do.

  • How to find the size and resolution option in the aspect ratio drop down menu for the crop tool

    while looking through certain tutorials on the new crop system i came across many that referenced the above mentioned size and resolution option in the  access ratio drop down menu.  They all mention a dialog box which then appears which looks really useful, however my version doesnt have this option. any help would be appreciated.

    Yes, definitely already differences. I sympathize with Photoshop instructors (online and offline).
    The headline change was Retina support but that was also made available to non-Cloud versions.

  • Circular and oval cropping at set size and resolution?

    I know how to use the M tool to create circles and ovals and i know you can set that to certain dimensions, but that doesn't do everything I need.
    How do you crop circles and ovals out of a photo, at a set size (for example, a 1 inch circle ) at a set resolution for printing?  What I need to do is crop circular and oval images out of a photo, say at 250 dpi, then paste them onto a blank white page for printing.
    So if I've got let's say a photo that's 14x10 inches at 300dpi, I want to be able to go in, crop out an oval or circle, with as much or as little of the photo that I can or want to, setting that automatically to a certain dimension and dpi, then paste it into a blank white page I've already created at that same d
    When finished I'd have maybe 20 or 30 images on a page that I can flatten all the layers and print.
    I can't find a way to set size and resolution with anything other than the regular square crop tool.

    You can make an action and use it as one step automation to achieve that on an initial selection.
    Step by step instructions:
    With the Elliptical Marquee Tool, make the desired selection on a image.
    Open the Actions panel (Window > Actions (Alt+F9), from its menu at the top right or corresponding buttons at the bottom, choose New Action, and in the dialog that appears press the Record button.
    From the Image menu, choose Crop.
    From the Selection menu, choose Inverse (Ctrl+Shift+I)
    Press the d key on your keyboard to reset the foreground/background color swatches.
    Press Ctrl + Delete keys on your keyboard to fill with white.
    From the Image menu, choose Image Size (Ctrl+Alt+I), make sure the Resample Image is checked, and in the Document Size section enter the desired dimensions and resolution and press OK.
    In the Actions Panel press the Stop Recording button.
    Now you can copy or drag the image to another image.
    For the next image make the oval selection, go to the Actions panel, select the actions you created above, and press the play button. You can also create a keyboard shortcut in the action's property accessible by double clicking the action.
    The creation of this action assumes that in the final image you will be composing oval images on white background without overlapping their rectangular bounding boxes. If you plan to overlap them then the action must be modified to make the image a transparent layer and delete outside the oval instead of filling with white.

  • Adjust front panel to screen size and re-position objects on different systems automatically

    Hello, i have designed a vi that contains 5 led's placed at the 4 corners and center of the front panel which occupies the entire screen. However, this vi is to be used on different systems having different screen sizes. But on every screen, i'll need the front panel size = screen size and the led's to  be placed to the centers and corner of this new screen size automatically without any manual operations and positioning bieng done every time. Will the resize option perform this task completely or do i have to go for some other techniques?
    Solved!
    Go to Solution.

    As far as I know, what you want is not easy to do but it is doable but you have to programmatically do it (no Labview setting). Here is an example for only 2 LEDs but I suppose that you will be able to make it work for your other LEDs.
    This VI maximizes the front panel and then positions the 2 LEDs in the center and top right corner upon running. The LEDs are positioned according to their own top left  corners, not according to their centers.
