ok here it is my duaghter pushed my powerbook off hte table and it broke the screen and i have purchased a dvi to vga adapter to work on a n external monitor is there anything else i need to do to make it work right now all i get is white screen anyhelp willbe greatly appreciated

The VGA adapter is only 4" long, do you have an extension? If so, the computer should register the adapter and the images should be displayed. Any more details would help to see what's wrong.

  • Monitor(video) on emac blew up, need help with external monitor....

    Hello everyone, I have an old Emac which the monitor popped and stopped working. I bought the plug and had an external older monitor working once, then I plugged in a newer monitor and now neither will work. The xternal monitor has a small blue rectangle bouncing around saying "please check pc display settings. I tried to reset the ram by restarting the Emac and holding down the command,option,p, and r buttons. This made the second restart sound, but the video still does not work. Is there another sequence to reset? Am I doomed now? Any help is appreciated. Thank you.

    Hello again, yes it was the picture tube that went. the smell was awful. The machine still runs, but since I plugged the flat screen monitor into it, it will not display either monitor. It was working once with an older monitor, but now it just diplays "adjust pc display settings". I needs to view the emac so I can retrieve my files. I've also tried resetting the pram, but that did not work. What can I do? I'm stuck. Thx.

  • Need help connecting external monitor

    My brother needs help with connecting an external monitor to his 20" iMac G5. He has the adapter with the standard monitor port, and when plugged in, the monitor duplicates the iMac screen. His question is, how can he set it so that the desktop is extended, instead of duplicated? I, myself, have a MacBook and two months ago I used my adapter to connect a projector, and I remember an option where I could choose between duplicate and extended desktop, and right now I tried to find it on my MacBook and well as my Intel iMac and I can't find the option, and neither can he.
    Please help, thanks!

    The iMac G5 can only mirror the internal display unless you hack the firmware. 
    Display options like that only appear when you connect a display which is why you can't see them on the MB at the moment.

  • Need help about external monitor

    Hi, I recently purchased a LCD monitor. And I use it as eMac's external monitor because I don't like the CRT monitor on the eMac. The problem is how can I turn off the monitor on the eMac and just use my external monitor as the main one???

    Po-Nan Lin,
    Welcome to the Apple Discussions!
    There's no switch or software patch that will blank the eMac's CRT while leaving the video out active. Short of ripping open the eMac and cutting the CRT's video cable (which not only obviously voids the warrenty but carries a definite safety risk due to the CRT's charge), there's no way to do what you want.

  • Need Help with External Hard drives and too much music

    I am not terribly tech-savvy, and I need your help. I have a G5 PPC dual processor with an internal 250GB drive. I have two seagate firewire/USB2 external hard drives. One is 250GB and one is 350GB. I want to know how to use them to get my Mac to run faster and better.
    My original hard drive is 7GB shy of being full. Almost half of this is my itunes library which is over 100GB. The older (250GB) hard drive has about 150GB of photos/videos.
    My Mac is running slow as molasses and when I power up the external hard drives it slows down to what I recall my original Mac Plus ran like.
    I use the G5 primarily to work with photos, illustrations and creating the occasional DVD with video and photos. the apps I use most often are Photoshop, Illustrator and Painter. I always listen to music while work.
    I hope all of this information is helpful! Here is my question:
    What is the best way for me to set up and use these external hard drives to return my G5 to its original blazing (to me) fast speed?
    PPC G5 Mac OS X (10.4.9)

    I think you should look at adding two 500GB internal drives. I'd say Maxtor MaxLine Pro for cost, but they also run much warmer (43ºC even when nearly doing zilch) so I'd go with WD RE2 500GB for $40 ea. more.
    dump whatever you don't need, trash anything that is hogging space and is just temp file or useless cache. Web browsers can leave behind a ton of small files eating up tens of MBs.
    Use SuperDuper to backup/clone your drive.
    Disk Warrior 4 to repair (after it gets to 15% free, or just forget for now).
    A 250GB drive formats to 240GB and you have ~3% free it looks like.
    For every data drive plan to have two backup drives.
    Keep your boot drive to 40% used.
    And your data drive to 60%.
    Backups can go a little higher.
    Drives are cheap and inexpensive, especially for the space and performance. And they have improved SATA over the years it has been out.
    By doing a backup followed by erasing your drive, and then restoring it, using SuperDuper, which optimizes the organization, skips copying temp files that aren't needed, it also defragments your files. I would do backup daily to different sets that you "rotate." And before any OS update. And do the erase and restore probably every 2 months.
    Make sure you keep one drive partition somewhere that is just your disk utility emergency boot drive that is not a copy of working system, used for doing repairs like running Disk Warrior and Disk Utility.
    You may need to repair; backup; even erase and restore your external drives. Rather than spend on vendor made case, just pick up a good FireWire case either with drive, or bare (and add your own). I think it'd add 500GB FW drive though.
    Why?
    To begin backup of your current drive. To leave your other FW drives "as is" for now.
    Then install a new internal 500GB drive as well so you now have a good current backup, and you have moved your data off 250GB to 500GB. If anything happens, you have one off line FW backup.
    Then begin to clean up, organize, and get your FW drives working. It sure sounds like they have had some directory or file problems.
    You can find a lot of Firewire and SATA drive choices over at OWC:

  • Need help with external hard drive!

    Hi all,
    I have been having trouble with my external hard drive.
    My mac is reading the disk however all my files from the hard drive are missing?
    In disk utility is seems to show that there are files on the disk but I cannot see them?
    At the bottom is shows that there are files on the disk!
    PLEASE HELP!!!!
    Here is a screenshot of my disk utility

    Ok just to clarify the format issue...
    Just move the data from the external drive, format and then move it back if you want, as JiveMasterT explained.
    If the external drive is FAT file system, then you don't need to format the drive unless you are planning on using the drive as an OSX backup.

  • Need Help with external display...

    First, let me explain what is happening. I'm using an external 19" Gateway LCD display with my Powerbook G4 1.25Ghz. Via DVI-D input. Everthing from connection to correct resolution is working fine. But the moment I change the refresh rate from 75Hz to 60Hz, the monitor starts to jitter or seems to have a nervous condition. The problem corrects itself only after a restart but I can change from 60Hz to 75Hz with no problem.
    Now, from my understanding refresh rate has no bearing on LCD monitors, is this correct? and why would the monitors manual say that the native refresh rate is 60Hz. So, I'm concerned if running the monitor at 75Hz will degrade or hurt it. And once again why does the monitor image shake when going from 75Hz to 60Hz but not vice versa.
    Any and all response with your experience is greatly appreciated.
    David

    You shouldn't need to adjust the refresh rate on an LCD display. Just leave it at it's default.

  • Need help with external user authentication

    Hello,
    I need some help to set up an external user authentication in Oracle DB 10g. Using the documentation at
    http://www.oracle-base.com/articles/misc/OsAuthentication.php
    I added the user alex to my linux system and checked the parameter os_authent_prefix:
    SQL> show parameter os_authent_prefix
    NAME TYPE VALUE
    os_authent_prefix string ops$
    SQL>
    I created the oracle user alex using
    CREATE USER alex IDENTIFIED EXTERNALLY;
    as well as
    CREATE USER ops$alex IDENTIFIED EXTERNALLY;
    The parameters in the sqlnet.ora are set to
    NAMES.DIRECTORY_PATH = (TNSNAMES, HOSTNAME, EZCONNECT)
    SQLNET.AUTHENTICATION_SERVICES = (ALL)
    Being the local user alex on the linux server I can login:

    - So, what's wrong?
    - Do I always have to create oracle users with the prefix "ops$" to the local username? How do these users login - with or without the prefix 'ops$'?
    - I read that kerberos authentication is only available through oracle advanced security addon. What about authentication through ldap?

    Obviously it doesn't work from any remote system.
    For this to happen the parameter remote_os_authent would have been set to true.
    Warning: this poses a security risk.
    As far as I know you should have been logged in as alex on the client, and using sqlplus /
    However, from 10g onwards Oracle comes with Oracle Wallet, which stores the password encrypted outside the database in a file, called wallet, and which is accessible from anywhere.
    You would better use that.

  • Need Help with External DVD Drive on my iMac

    Hi, This is my first post and I hope there is someone out there that can help me. My PC just died and I'm finally moving on and taking it where it belongs, the dumpster. Anyways, I've been using my Pioneer DVD burner in there and now I'm trying to use it on my Intel iMac. When I hooked it up using an external firewire case, this is what shows up in my profiler.

  • Need Help with External Storage

    Hi,
    I have a MAJOR problem that I can't for the life of me figure out. I just got a new macbook and am making the switch from PC's. All of my itunes music has been stored on an external linksys hard drive, and I want to keep it there, but share the files wirelessly on my macbook. When I try to set up my library in itunes by holding down the option key then navigating to the external drive, itunes tells me there is no itunes library there. ALL the MUSIC is there, as I can see it, but it seems as though it is just not set up as an itunes library file, so itunes won't let me access all the music, as it doesn;t see it as a "shared library".
    So, um, any suggestions? HELP!

    Welcome to AD!
    So do I have this right, your PC's ITL file is on the exHD?
    I have gotten my iMac to see my PC's ITL file wirelessly. The sharing of files between Mac and PC is often goofy and permissions not always correct. I'm sure it's some setting I don't know about. It kept giving me a message about library not getting saved due to lack of permissions.
    But anyway. On my iMac, I plugged in the exHD I'd been using on my PC. In Mac finder I had to browse to the ITL file, right-click and Get Info. You need to tell the Mac to open it with iTunes. The default is a 'unix executable file' originally, as Mac doesn't know what to do with the ITL file extension.

    Using this xorg.conf file, only my NEC LCD analog monitor could display KDE while the Samsung digital can't.
    Any suggestions?   

    Thanks for your help guys, I'm halfway there.
    The second monitor shows the KDE desktop, but it isn't exactly what I expected.  Right now, both monitors display at 1024x768 (each) or 2048x768 (total).  The larger monitor stretches and distorts the display of 1024x768 to its natural resolution at 1440x900 and it isn't what I wanted.  Other than that, the dual desktop setup behaves what I expected to.

  • Need help with a Asus 27" monitor with webcam problem.

    Need help with a Asus 27" monitor I bought.  Model VK278Q.  The issue is that the webcam will not work properly.  Various applications can see the webcam, but I just get a black box.  From what I have read, the issue seems to be that there are no official drivers for the webcam. 
    I thought someone in this community might be able to offer some help before I return the monitor. I read somewhere that it may be possible to tweat the OS so that the iSight software will work for the monitor webcam.
    Thx

    Eureka! You now understand the situation.
    Even the old standard for Mac OS X drivers for non-compatible cams, macam, says that it has no driver for ASUS (20") monitor camera.
    The macam status shows:
    not working (no documentation)
    With no working driver for the 20" ASUS, it is not surprising that there is none for the 27" either.  There may be good reason that ASUS won't (or can't) offer either the technical documentation or a Mac driver for their monitor's inbuilt webcam.  However, they apparently do not publish that information. 
    If ASUS Technical Support cannot provide the driver you need for OS X, the ASUS will continue to be a ridonculous (sic) monitor whose webcam will not work with your OS X Mac.  The only other simple fix I can think of is to use the ASUS with a different PC that is compatible with this monitor and its inbuilt webcam.  What you do is certainly your choice.

  • Need help with networking external hard drive

    Hi,
    I am working on a corporate network and I have a Western Digital My Book Studio Edition external hard drive attached to a Mac OSX 10.4. i have other Macs connecting through the network to this Mac and accessing the external hard drive and it works just fine for that.
    What I need help with is the fact that I also have several PCs on the same network (all XP), that need to connect to the hard drive and access the files. I've been able to connect to the Mac using the XP by accessing the IP address. I also set the Mac up with password credentials so that I had to log in to the Mac to access the files. But when I try to access the Mac, it only shows the main computer drive as the only available share and no external drive.
    Does anyone know how to access a Western Digital external drive on a Mac from a PC through a network?

    For an external hard disk drive or other (different) system shared
    storage devices to work, they probably should be formatted in a
    format seen by both operating systems.
    If the WD unit is not seen by Windows computers on your network,
    the WD may have been formatted in HFS+ for the Macintosh. That
    is OK unless you need a Windows computer to access the same.
    The Macintosh can see and use a standard Windows disc format;
    so the external drive may need to be reformatted away from HFS+
    if that is really what is going on (and archive any data on the suspect
    drive elsewhere, since it will be lost to reformatting overwrites)
    and then both Mac OS X and Windows should see the files on there.
    And Macs set up to run Windows may also see the non-Mac format;
    without having to re-boot via BootCamp, if that option is in use.
    As to the other question(s) I really have no idea at this point in time.
    And since that may be the rub, hopefully someone will follow up here.
    Good luck & happy computing!

  • Need help with threads?.. please check my approach!!

    Hello frnds,
    I am trying to write a program.. who monitors my external tool.. please check my way of doing it.. as whenever i write programs having thread.. i end up goosy.. :(
    first let me tell.. what I want from program.. I have to start an external tool.. on separate thread.. (as it takes some time).. then it takes some arguments(3 arguments).. from file.. so i read the file.. and have to run tool.. continously.. until there are arguments left.. in file.. or.. user has stopped it by pressing STOP button..
    I have to put a marker in file too.. so that.. if program started again.. file is read from marker postion.. !!
    Hope I make clear.. what am trying to do!!
    My approach is like..
    1. Have two buttons.. START and STOP on Frame..
    START--> pressed
    2. check marker("$" sign.. placed in beginning of file during start).. on file..
         read File from marker.. got 3 arg.. pass it to tool.. and run it.. (on separate thread).. put marker.. (for next reading)
         Step 2.. continously..
    3. STOP--> pressed
         until last thread.. stops.. keep running the tool.. and when last thread stops.. stop reading any more arguments..
    Question is:
    1. Should i read file again and again.. ?.. or read it once after "$" sign.. store data in array.. and once stopped pressed.. read file again.. and put marker ("$" sign) at last read line..
    2. how should i know when my thread has stopped.. so I start tool again??.. am totally confused.. !!
    please modify my approach.. if u find anything odd..
    Thanks a lot in advance

    This master.java program will run continuously for days or weeks, each time through the loop starting another slave process which runs for five minutes to up to an hour, which means there may be ten to twenty of these slave processes running simultaneously.
    I believe threads is the best way to do this, but I don't know where to locate these slave programs: either inside the master.java program or separate slave.java files? I will need help with either method.
    Your help is greatly appreciated. Thank you.
