PowerPC :: Display Error When Hooking Up Powerbook To External Monitor?
Mar 7, 2009
irst off, according to mac tracker the Powerbook I have is the Powerbook G4 15 inch FW-800. I am running Mac OS X Leopard 10.5.6
Alright. About one week ago, I hooked up the powerbook to a 19 inch external LCD monitor with a DVI to VGA convertor, and all was well. It found my supported resolution and everything, worked straight away, etc.
Fast forward to today, at about 2pm (4 hours ago) I was using the computer and everything was working fine, but I had left it on for a few days so I shut it off when I was about to take a nap. I wake up from said nap about 20 minutes ago, turn on my Mac and my external display is only showing up at 800x600. I have no idea how this could have happened. This would not be an issue if my monitor's native resolution of 1440x900 were on the massive list of resolutions to chose from, but alas it is not.

For the past few months i have been using an external display hooked up to my 12" powerbook g4. I have had it on a dual display mode so no mirroring. Recently i would open the laptop lid waking it from being in sleep mode and my internal display will not turn on. The apply system profiler does not even recognize that the internal display exists. My external display works fine and has always been set as the main display. If i go to detect displays nothign happens. I have tried restarting the computer, instering system disks, unplugging the external and nothing has worked. I simply cannot get my internal screen to fire back up. When i used to unplug my external display the internal display would switch back to being the main display and everything would be fine. Now i cannot get the internal display to function whatsoever. Please try and help me as a need this laptop working and i will be ordering a mac pro soon for use with my external display.

I have a 14'' iBook and recently bought an LG 19'' Widescreen monitor. I am testing a Dell 17'' on it right now before I open the LG one, but my problem is that the same screen shows on my ibook and the external. This isn't what I want. I have read you are supposed to be able to close the laptop and then it shifts to the external display but this is not working for me.
This is my goal:
Use my bluetooth keyboard full time
Have my ibook closed at all times
Have my external as my main display
How do I make this work?

My friend has a PowerBook G4 and he wants to connect it with an external 20" Apple Cinema display. His friend told him it was not possible to connect it, but I am not certain if this information is correct. He asked me to help advise him on this, but unfortunately I don't know enough about Apple hardware to give him the information he is looking for. I am wondering if anyone happens to know the answer on this.

I read the thread about how to pivot your screen over in another section but it didn't address what to do when it goes wrong. And it did...very wrong. I'm running a Powerbook G4 Titanium 15" laptop with Tiger OsX 10.4.11 and I hooked an external monitor to it. I was playing around with the settings and saw the rotation feature, which wasn't available until I attached the external monitor. As soon as I clicked on 90 degrees, both the main screen and the external fritzed out. I could vaguely see things through the haze on the main screen but the whole thing had stopped responding to all mouse and keypad commands. Eventually the only thing I could do to regain control was a hard shut off with the power button and unplug the external. After that the main screen booted up just fine but the moment I hook up the external again they go blue screen of death on me and I can't see what I'm doing to undo what I did!! I tried hitting the manual reset on the screen itself, which I didn't really think would work but hey, desperate times...
After some research on the internet I found out that, contrary to what the other thread says, not all Tiger enabled computers can run the rotation function, apparently because the scan rate, or something like that is too low. Which is why the option was disabled when only the main screen was running. Nice to know and would have been good to know sooner but what I need help with now is HOW DO I FIX THIS MESS?!!!! Some sites mentioned archiving (I'm moderately computer savvy but I'm not totally sure I know how to do that) and some have mentioned the boot disk, which I have but I want to make sure I know what will happen if I do that. I've backed up my files just in case. Will it erase the programs I've installed or just my settings? Or is it much simpler and is there something in the utilities I can mess with that will reset stuff?

I have a G4 powerbook with an LCD that only displays the top 25% of the screen. I've been using an external monitor with it just fine. Today, I reinstalled the OS and ran into a problem. The main OSX startup menu (you know, where it asks for your location, timezone, personal info, etc) is prompting me for information, and I can't see the forms to fill them in! The external monitor defaults to "extended" as opposed to "mirrored", and the forms are embedded, meaning I can't drag them over to my external monitor. Obviously, if I can't fill out these forms and get to the desktop, the laptop is completely useless.
Does anyone know how to force the external monitor to be "mirrored" from startup? Is there a keycommand?

Looking to get a monitor calibrator for my powerbook. I have about 750 pictures I need to edit for print via an online print shop but am having a hard time configuring my powerbook screen. I am partially color blind and wear glasses so using software hasn't worked very well for me. I was wondering if anyone could reccomend any of the hardware monitor calibrators.

As said, my current set up is an HDMI - DVI cable (HDMI to monitor and DVI to adapter) and my DVI - mini DisplayPort adapter, everything is connected fine but when I turn on the monitor, it says cable not found... and nothing is displayed on the screen but on the Macbook side of things, it sees the monitor is connected (I can extend the screen and leave the screen) but other than that, it appears I cannot get an image on the monitor, pressing every button on the monitor does not work either.
Any other information that may seem necessary, let me know. I tried clearing my PRAM and clearing the power and such but nothing seems to work.

I'm experiencing a problem with my monitor on my 1.67 GHz PowerPC G4 recently. A few weeks ago the monitor would dim when extended past parallel. Now It dims past 30 degrees. It seems to be getting worse by the day. Anybody have any ideas why this is happening, and more importantly; how to fix it? By the way, I don't know much about the insides of these things.

I have a Macbook Pro 2.16 Core Duo, and I'm wanting to install 10.6, but about a year ago, I cracked my screen to the point that I cannot make anything out on it, and haven't replaced it. Instead, I have just been using it in clamshell mode, which has worked out fine so far. My problem is that I cannot get the 10.6 install to show up on my external monitor.
I searched around, and could only find one other similar thread that just ended with the author putting it in clamshell and having it work fine. When I boot to the install and close the screen, I just get a grey box on my external display with a black bar on either side of it. I can't seem to find any other resources, so I'm not entirely sure what to do at this point. Any help would be greatly appreciated.

I am currently experiencing the issues displayed here... http://www.apple.com/support/powerbook/displayprogram/
However my serial # does not fall within the ones specified. My powerbook was purchased in early Sept of 2004, and I have applecare so it will be up in Sept of 2007.
I am unsure of what I should do at this time and am looking for recomendations of how to handle the situation. I am aware that apple will probably try to say that is it somehow my fault and that i put too much pressure on the lid of the powerbook (as this happened to a friend of mine, and she was actually within the serial #'s that were specified in the link above)
I have kept my powerbook extremely protected (at one point I even had it in a neoprene sleeve inside of a hard sided zip case!) and really don't think it's anything i've done, or wear and tear on the notebook (it's in near mint condition other than a few spots just below the arrow and command keys.)

I just bought a 23" ACD and I'm having trouble getting it to work with my 17" Powerbook. I checked it in the store before buying and it worked fine, but at home it's not responding. The display is recognised in Preferences and is giving me a choice of resolutions, the light is on, but I can't get the screen to show anything. I've tried adjusting the brightness to bring up an image to no avail, turning mirroring on, and closing the lid on the Powerbook then waking it again but nothing gives me an image on the 23".
My Powerbook is a 1GHz 17" with a GeForce4 MX 64 MB.

when I woke my pbook up the screen had a horizontal line across it, and below that there is doubling and tripling of the screen image going on. Rebooting didn't accomplish anything and when I take a screenshot it doesn't show up there. I have a 12" Powerbook G4, running os 10.4.11.

The connections won't allow me to hook up the new LED display to my PowerBookG4 (Mac Pro on the way), but I'm wondering whether I can still just use iSight safely without using the actual display.

I just bought a Powerbook G4 off of Clist. The previous owner replaced the screen with a higher resolution screen from a newer Powerbook. The display looks great, except that it doesn't fill the whole screen. There is a long group of colored lines on the right side, and the bottom starts to show the top of the display (it looks almost tiled and shows the screen again on the bottom). I'm guessing that this is just a formatting issue, but I'm not sure how to correct it.

I've recently purchased a broken 1GHz Alum PowerBook G4 12", and the display isn't working. I have a total of two 12" PowerBook displays, and I've tested both. They've worked perfectly fine. Then I've tried reseting the PMU and PRAM, no luck, but they've attempted to work. Tried the Mini-DVI to VGA adapter with my display, still no luck. The keyboard, optical drive, and hard drive works as if it was booting, and there was always a clear chime, even when I've reset the PRAM and PMU (the beep sound when PRAM also attempted). I've inserted a Leopard install disk, and it sounded like it was working perfectly fine. Hopefully it's not a motherboard issue

i've plugged my lcd tv to my powerbook using the dvi port and a dvi-to-vga cable and have extended the desktop to the left of my mac's monitor so i can throw windows and stuff there when i'm working (web design). because i would ideally love to have even more room to have my stuff laid out, it would be great if i could connect another monitor and extend the desktop to the right this time... is that do-able? could i use the s-video port for that?

I am trying to do a clean install of OSX 10.5 on my old powerbook G4 15". I am using a 10.5 image file on my external. I partitioned the external using GUID, and restored the image file onto the external. (this method works when installing on intel macs). Unfortunately, I cannot boot 10.5 using this method on my powerbook. Is it because i am using a firewire 800 cable? Should I be booting it using a firewire 400? I know that PPC macs cannot boot using usb, so i am stumped.

I have an old iMac G4 and I was wondering if I could just use the screen somehow since I don't need to use it as a computer? Could I use it like a TV to play xbox or something?

I have a powerbook 12' 867 mghz, I know I would rather have a new one, but not ready to give up on this old gal yet! Anywhoo I thought the logic board was fried but after letting the powerbook "rest" I came back months later and sometimes it will boot but as soon as I try to do anything it freezes, so maybe the harddrive is fried? How do you get it to ignore the internal drive so it will boot from an external?

I'm after a bus powered 500GB external drive, but I can't seem to find one that runs on 1 USB connector alone.I just had to return a freecom unit as it would only run with the USB data and a seperate USB power lead connected.Does anyone know of somewhere in the UK that does either a firewire or USB 500GB notebook size drive that will run from one lead?

I just started using my MacBook with an external monitor, and love this new set up. But, I have a quick question. When I hook it up, my screen looks like an enlarged version of what's shown on my smaller MacBook screen. This is okay, but I'd like everything (dock, menu bar, etc.) to be the same size as on the MacBook screen, only with extra desktop space, if that makes sense. Currently, since everything is just enlarged, I don't feel like I have any extra screen real estate - windows and the dock take up the same amount of space relative to the screen size as they do on the MacBook. My resolutions are 1280 x 800 on the MacBook and 1280 x 720 on the external monitor. I tried playing around with different resolutions but keep getting a No Signal error on the monitor when I use anything else. I know this is kind of a difficult question but does anybody have any ideas?

I have been using my MBP (2010, i7 17" model) with a 24" HP external HDMI LCD monitor. The connection is via the Apple's Mini DisplayPort to VGA Adapter. It was working perfectly the first day I tried. However, when I connected the external monitor to the MBP yesterday, I found that the LCD screen of the external monitor was blinking. It lasted for about 5 minutes and then the problem was gone by itself. I have just reconnected my MBP to the monitor again. The problem reappears. Anybody knows what is going on and how to fix it?

I've got a 15in Titanium Powerbook which I've had for about 4 years and can't see any reason to change it. I'm running OSX 10.3.9, 867Mhz processor, 1MB L3 Cache and 1GB SDRAM. I'd like to get an external monitor, at least 20in, maybe a 23in. I have a few questions though.
1) A fellow mac user said my PB might struggle to power the larger monitor due to the older graphics card. Is this true?
2) If yes... are there any upgrades I can do to allow me to buy an external monitor?
3) If its fine, any recommendations on monitor? I can afford the 23in Apple Cinema, but I don't like spending money for no benefit. How are the other options compared to the Apple? IE Dell/Samsung etc.
4) Anything else I should check/know before purchasing?
5) Any recommended UK sites? If I go Apple I'll go to Regents Street, but what about other options.

A while back I bought an external hard drive for my PC, but then ditched the PC and decided to hook up the hard drive to my Mac. My External Hard Drive is a: 149.1 GB WDC WD 16 00JB-00GVA0 The problem is, I can access all the information but it will not let me do anything on the external harddrive (Like creating a file, copying and pasting a file on there, etc.) However, I can save Torrent downloads on the harddrive, but they do not show up on the actual external hard drive. But, when I press the "Find/Show directory" button in Bittorrent it does find the files. Is there something I need to do, Or is it just incompatible with my Mac?

I have a 12" Powerbook G4 running 10.3.9 Panther. I am having problem booting my computer from a Firewire HD. I have done a search in the forum but cannot get a definite and/or successul solution. Forum moderators and my respected macrumor fellows, please feel free to direct me to a specific link if you find the questions redundant.Recently, I have had the HD making terrible noise and several days ago, the computer cannot boot at all. When I pushed the power button, the screen shows a folder in the middle with a Mac face and switches to a question mark back and forth. However, it just gets stuck at that stage. I suspected that I have a HD problem and wanted to boot from my clone Firewire HD. Unfortunately, the computer will not boot with Firewire HD either.
