Hardware :: Powerbook With Broken Monitor - Force Boot To External Monitor?
Jan 31, 2010
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?

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.

I have been using the latest macbook pro 13.3" since April 2010. Over the last week the monitor suddenly goes completely white and the external monitor goes black. The laptop becomes unresponsive although the programmes opened continue running (e.g a skype voice call would continue without interruption although the monitor is all white).
The only solution at the moment is to press the turn off button for a few seconds then switch the laptop on again. It will then work normally until for no apparent reason this happens again.

I have a 27" i7. I have a 24" DVI Montior hooked up to it via MDP->DVI adaptor. When the 24" Monitor is on, everything is fine. When I turn the monitor off, the magic mouse tracking on the 27" screen stutters. I am not kidding - it took me ages to figure out that to fix I either need to turn the other monitor on OR disconnect the MDP->DVI adaptor.

I picked up a new MacBook yesterday and I noticed a weird issue when coming out of "monitor sleep" mode, not regular sleep mode.
When I move the mouse, the external monitor shows what you see in the picture, kinda like a TV with no signal. The MacBook screen works fine so what I just do is unplug and re-plug in the DVI plug and everything is good again.
My 24 inch Dell monitor worked fine with my M1330 and other computers so I know it's not that. Does anyone have the same issue or maybe give me some light on this?

Is there a way to use my external monitor as my only monitor when connected to my mbp? Or, can i clone my display, but at separate resolutions? I am able to do this on windows with nvidia software, is there software that allows further customization?

I have a 22" Dell external monitor on my MBP. I know that I just close the cover to my MBP to shut off the screen. What do I do in those instances that I want to use both screens? There has to be something simpler than restarting the MBP?

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.

Computer: Macbook Pro 13 inch purchased Spring 2011 OS: Mac - Lion (10.7.3), Boot Camp - Windows 7 (64 bit) Utilizing an adaptor, I'm able to use my Samsung monitor without I problem when working in the Mac operating system. Unfortunatlely, when I switch to Windows 7 / Boot Camp partition, plugging in the Samsung makes both the external and laptop monitors go blank. I have spent hours researching this, but I have be unable to come up with solution. It seems like the problem might have something to do with the NVIDIA drivers.

**Intel Imac 24 in. 2.4GHZ Core 2 Duo (NOT G5...my bad)
I know the "Using imac as external monitor" topic has been adressed in previous posts and it apparently can't be done. But this is slightly different.
I have this Imac G5 24" that is currently out of order. (won't detect hard drives when powered on 90% of the time and when it does i am experiencing ridiculous lag and random shutdowns...not to mention crazy overheating)
I sent it to tech support and after changing the hard drive, power supply etc.. and still not seeing any improvement i just stopped sinking money in repairs and got a new imac.
So now i just have this useless imac laying around and i figured i might as well try and recycle it into a secondary monitor.. I don't mind hacking it open since i have nothing to lose. I was just wondering if it could be done and if so would it be very complicated? I would rather pay a few hundred dollars in wires and IT than buy a cheap external monitor since its already a decent quality monitor and it matches the new imac

Can i use My Old iMac as a extra monitor. My Old iMac from early 2008 has a broken graphic card nvidia 8800 gs. When I start it up I hear the bong and see the symbol spinning then the screen goes black from right to left the computer is running but I can't use it. I assume it's the graphic card. Can I use this iMac as an extra monitor to my other iMac.?

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.

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 fresh install of Windows XP, service pack 2 on a boot camp partition on my macbook (13" first gen aluminum case) and a Apple LED Cinema Display attached to the mini display port.
I can't seem to make the Cinema Display the primary display (the "Use this device as the primary monitor" checkbox is always greyed out in the Display Property Settings tab). I also can't shut the macbook lid and continue to use it closed (with kb, mouse and monitor attached) like I would when booting OSX.
Is there some other way to make the Cinema Display the primary monitor, so I can leave the macbook closed when booting into Windows?

I have a macbook pro from 2007, and I just popped into a tagsale and picked up one 2001 Mac Studio Monitor and a 2001 Fomac Gallery monitor.. So I was hoping to use the monitors with my laptop because the small screen on this laptop is KILLING me, and i'm not yet prepared (financially) to get a powermac.. Paid $10 for both of them..
my issue right now is, the monitor's cable doesnt match the input on my compuer. I need a ACD DVI clip cable.. Now, i looked them up and the price is $100! Call me naive, but i had no clue a connector cable would ever cost that much..
So basically, I am curious if there was a different option to get this to work with my computer OR if there is a place to get a used or "extra" cable

I have a G5 Quad with an Ati x1900 graphics card running into a 52" Samsung LCD. This was working fine through a dvi-vga adaptor until I switched the monitor resolution from 1920X1080 to 1360X768 which is not supported by the monitor .....blank screen. I plugged another 19" monitor into the other output on the card and both work fine but as soon as I remove the 19" the 52" reverts back to the unsupported mode. I have reset the pram and tried booting in safe mode but that did not help me. From bootup the 52" works fine until just before the login screen, then it switches resolution......blank screen. Would anyone know where these settings would be housed in OS 10.5.1 so I can modify (delete) them?
Information:
G5 Quad
Mac OS X (10.5.1)

i don't know what I did, but for some reason, new windows on firefox opens on my laptop monitor (instead of my 20 inch LCD, I am running dual screens).
1. I am running dual screens, but my EXTERNAL monitor is the primary one (top menu bar is on the external monitor)
2. All applications open by default on my main monitor, except for FIREFOX.
3. I have tried dragging the firefox window back to main monitor, both in spaces view as well as normal view, to no avail.

I was surprised one day to find an inch of white line running from top to bottom on my screen. Then after a week it expanded to two inches white line, then suddenly it turned all black and I can't see two inches of my screen from the right edge. I was reading some forums and found out that I can use a dell monitor as a secondary monitor, but is it possible to use the dell monitor as the primary monitor in case the black line will spread throughout the entire iMac screen? so the iMac would serve as a stand alone processor like a regular desktop?

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 have a new Mac Mini connected to an older VGA monitor using the Apple brand VGA adapter. The mini is fully up to date and runs perfectly when booted. However, if I reboot the mini with the VGA monitor connected, it fails to boot. I just hear the faint chime sound every other second. There is no output to the monitor and the only way I can get it to boot is to disconnect the monitor and then power cycle the mini. I can reconnect the monitor just seconds after powering back on and it finishes booting properly.
I've also tested with an HDMI connected monitor (without the VGA adapter) and it boots just fine and the display works properly.
Info:
Mac mini, Mac OS X (10.7.4)

I've got the older white macbook laptop. Just got delivered was my brand new Dell U2410 monitor (drool) and the adapter from apple that converts mini dvi to dvi-d. The monitor is sitting here and i plug it into my mac via the adapter using the dvi cable provided by Dell and the external monitor displays the default apple background and I can move my mouse around on the screen but that's it. How do I get it to work properly? Do I have to use a separate mouse/keyboard or can I use the macbook keyboad?

I know this is a basic question, but for some reason i just can't seem to figure out how to use my 24" Apple cinema display with my 13" MBP as a second screen. I obviously want to use the 24" display as my main screen (when connected to my 13" macbook) but for the life of me I can't seem to figure out how to use my MBP as a secondary iTunes, etc. screen. I typically use my macbook in "clamshell" mode with my 24" display and when I open the lid of the macbook, it's just black as if the computer was asleep but it fails to wake up when I press any buttons on the keyboard . When I unplug the mini display cable, the external monitor goes black and I'm reverted to using just my macbook. I know this can be done. Does anyone have any experience with the 24" Apple cinema display and MBP?

By using boot camp, I finally managed to install XP on my Macbook Pro. I can extend the monitor but the problem is that the extended monitor is in Black&WHite and totally jagged/off centered. I tested the adater and the cable with other machine and they work fine, so definitely issue is not the cable and the adapter. I really need to use Dual monitor for some software that I use on XP, so this is really really important to me.... My MacbookPro is 2.16ghz with 2GB of RAM, and the video card is ATI Radeon X1600. Maybe I need to install different driver for the card? If anyone has done the same please please let me know exactly how you did it

I have my MacBook Air hooked up to a 46" HDTV so that I can play games on the big screen.
Problem is, I notice a slight lag with the mouse when looking around in the game on the big screen.
When I look at the game from my MacBook Air there is no lag with the mouse.
I heard theres a mode called "clamshell" that would fix this but don't know where to find it or enable it.
Info on fixing the lag from the big screen so that games could be playable when watching from the big screen.

Macbook Pro last years model. I use external monitors alot for video DJing. I normally go DVI to VGA using the adaptor that came with the MBP. The other night I tried a different adaptor- DVI to composite. Now when I go back to the DVI to VGA my external screens have a yellow green tinge to them. I bought a new DVI to VGA adaptor and that didnt help. I calibrated the color profile, detected displays. and still the external screens are a yellow green color. You can still see whatever Im playing but there is definately something wrong with the color.
