Question about Apple 15" PowerBook G4 Aluminum 1.67 GHz LCD Display (p/n 1002587) (661-3749 1002587) Mac Notebook

2 Answers

Display size / resolution

I have a G4 17" but i don't think it should matter.  What the problem is during initial boot up the display size is perfect 1440x900 - and everything fits on the screen ie. the top left side has the APPLE logo and the top right hand side has SPOTLIGHT - and also the DOCK all fits.  But at the end of the boot up - the LCD displays changes resolution so now the virtual screen is larger than my physical screen.  I have seen this in Windows and I have been able to fix it but I can not find how I can fix this resolution display size back to the original.  ie. that I can see the whole virtual screen on my display.  I hope that makes sense and pray that someone can tell me.  I have tried going into sys pref and performed a detect display and played around with the settings there but no result the virtual screen is still larger than the physical screen.  Sorry for the longish desc.  thanks in advance.  Perth guy.

    Hi ya.
    No matter what the res of the screen is it should still display your top menu etc.

    So after the machine is up and running your nav and doc disappear?
    Are you able to see anything? Does the doc magnify when you mouse down at the bottom of the screen?

    You've been to display pref' and changing res does nothing?
    Do you have access to another monitor that you can plug into your machine.

    If you can do that open display panel and look under arrangement. You should see tow screens. One with a red line around it. Try dragging that over the second monitor or switch on mirroring to see if the apple menu appears.

    That would be the first try before re-installing software.

Just gonna toss out a couple of questions here: 1) what do your startup items contain? since login and bootup sequence finishes completely (i.e., you see a dock and top menu), this sounds like a startup procedure kicking in. i'd look at startup items in your /Library and ~/Library directories, as well as maybe even /System/Library/StartupItems. something is resizing your monitor upon startup but only after full login and bootup. 2) Assuming the problem hasn't always existed, can you time it to a particular period of time? have you tried going into ~/Library/Preferences and viewing by modification date and pulling out a modified .plist file that would have to do with your screen resolution or virtualization of your screen, even just the standard type stuff?

hope that helps!

Hi thanks for this but no to no avail. There is nothing wrong with the display itself - everything works but the problem is that the VIRTUAL size of the screen is 1500 x 950 instead of 1440 x 900 if you get my meaning. I wish i could find a way to shrink back the virtual screen size to 1440 x 900 so that it fits the exact physical screen. ie. if i was to play a DVD on full screen i would only see 95% of the picture because the virtual screen is larger than the display. And the virtual screen would move right if I shifted my mouse to the right edge. Still puzzled.

How do I change the screen size

By screen size I'm going to guess what your asking is how to change the resolution of the screen so that the graphics of the icons and what not are larger or smaller, since you have a laptop you are not actually able to change the size of the display itself, and with a macbook that's a older model you might be able to do a dual display setup, but if you're simply mirroring the built-in display then you are really going to bog down you're processor and VGA's performance. To change the resolution just go to "system preferences->displays". Now look for the option that says "resolution", there should be choice two options, one that says "best for display" and one that say "scaled". You're going to want to make sure that the option "scaled" has been selected, if it wasn't previously then when you select it a small menu box will now appear with different resolution matrices. I would try just selecting the matrix below the one that is currently selected to start with, if you don't like it you can always change it back to the original or keep going until you find the one that best suits your preference.

if you have any additional questions or require additional help, please feel free to ask, but place them in this message string so I am notified and they are easy to find. If you found this advice useful please up vote my comment, and let us know your results!

    How do i change text size on OSX 10.9.2?

    Open the System Preference folder, go to "DISPLAYS" select "SCALED" choose the resolution yoiu desire, this will be trial and error until you have the resolution you are comfortable with. There are are other less permanent ways to do this. hold down the shift key, omand key at the same time, then press the " + " plus key. to revers the size is the command key and the " - " minus key.

    What happens when you change the display resolution setting? Maybe the program was written for a different resolution, so the pixels are the wrong size. That may account for the misbehavior, and very likely the menu issue. To change display resolution, open System Preferences... from the Apple menu, then click on Displays. Try a higher resolution (bigger numbers, e. g, 1280 x 854)) first if that is available. This may scale the menu and play area to their intended sizes.

    How to increase font size on my macbook permanently.

    When you are on the finder Click View, scroll down to 'show view options' and from there you can change the font size looks on the desktop. You can even make the folders bigger.

    To make the font bigger for folders open the desired folder you want and go to the view menu and like above goto the "show view options' option and when the window pops up you can adjust the font size.
    I also suggest dropping your screen resolution to a lower number. That can be found by clicking the apple, going to system preferences and click displays under the hardware header. From there move the resolution down to 1280 x 800 or 1024 x 768. But for screen legibility and such I would not drop the resolution any farther than 1024 x 768.

    Hope that helps!

    My font is too small on my computer how do i change it?

    In Mac OS X, it is not possible to change the system font size directly. You can however change the resolution by
    1. Going into System Preferences
    2. Under the hardware section, select Displays
    3. Change to a desired (or usable) resolution
    And that's it.

    My desktop moves everytime my mouse moves.

    probably by mistake you set a display resolution bigger than your screen size, try lowering the display resolution to something typical such as 1024x728 or even 600x800 and see if that fixes it.

    Opening files at correct size and quality in indesign cs2

    This is from the InDesign help file.  I think it explains what you're experiencing:
      When you place a graphic, its original file is not actually copied into a document. Instead, InDesign adds a screen-resolution version of the file to the layout, so that you can view and position the graphic, and creates a link, or file path, to the original file on disk. When you export or print, InDesign uses the links to retrieve the original graphics, creating the final output from the full resolution of the originals.
      Links can help minimize the size of a document by storing graphics outside the document file. After placing a graphic, you can use it many times without significantly increasing the size of the document; you can also update all links at once.
      If the bitmap image you place is 48K or smaller, InDesign automatically embeds the full-resolution image, instead of the screen-resolution version in your layout. InDesign displays these images in the Links palette, so that you can control versions and update the file whenever you like; however, the link is not necessary for optimal output.
      Note: If you move a document to another folder or disk (for example, if you take it to a service provider), be sure you also move the linked graphics files; they are not stored inside the document. You can copy all related files automatically, using the Preflight and Package features.
