Using an extranal monitor ONLY on a iMac

I have a 17" iMac Intel based, and the screen is developing vertical pixel lines. I am up to about 20 now and I have no interest in the cost of replacing the screen on this out of warranty system. The computer itself functions just fine for our needs. For now I have a external monitor setup, in a mirrored configuration and simply sitting directly in front of the iMac. Is there any way to actually disable the built in screen entirely?
Secondly, anyone know what the max resolution the external screen can be? Right now I am using the 1440x900 on a 19" monitor, but I was going to get a 23" and wasn't sure if it can support the larger resolutions or if I am capped at 1440x900.

You may be surprised to know that there is a repair program for these bad displays if your iMac is part of the series of serial numbers covered in the program.
Read the last 20 or so comments in this thread to get the details and to pick up the info you need to make your case with Apple for the repair.

Extern monitor only when connected?

hi, i have a big problem, i have a macbook pro 3,1 running arch with nvidia driver, and i have an extern monitior, which i want to use, if plugged in on dvi.
i want to use the extern monitor only, no macbook screen, i know i can enable the monitor with nvidia-settings, but when i shutdown, disconnect the monitor, and for example have a journey with the train, then my macbook cannot be used, because the configured screen is the extern monitor, and the macbook screen is black. no hotplugging here
if theres no clean solution for this problem, maybe there is a cmd to switch to external monitor only, which i can enter manually every time i need the extern screen, and after reboot it switches back to macbook screen?
i hope someone can help me....
regards chief

You can try something like this in your .xinitrc
xrandr | grep DVI | grep " connected "
if [ $? -eq 0 ]; then
xrandr --output LVDS1 --off
xrandr --output DVI --auto
fi

Imac G5 use as a monitor

Is there a way to use a G5 imac as a monitor? The processor is dead but the monitor still works.

Hi, negatory...The only Macs that can be used as a Monitor are the new 27".....L

Use a second monitor on a iMac G5 without iSight.

I'm wanting to use a second monitor with my iMac G5.
My iMac doesn't have Front Row or the iSight camera. It's the G5.
I know that I need a cable that's the Mini-DVI.
But the problem is that my monitor I would like to use as a second monitor doesn't connect through S-Video, it connects through a VGA. Is there another adaptor?
What do I need?
Pardon, if I have posted this message on the wrong area of the forum.
Any links, suggestions, ideas, or anything would be greatly appriciated.
Thanks in advance.

I know that I need a cable that's the Mini-DVI.
Actually that's wrong. You need the Mini-VGA to VGA adapter, referred to in the Apple Store as the "Apple VGA Display Adapter".
I trust that you are aware that your iMac officially only supports video mirroring, so that any external monitor you connect will show the same picture, at the same resolution, as your iMac's internal screen?
BTW, for future questions, I'd suggest you try asking in the iMac G5 area. This forum is for the new Intel-based iMac and so perhaps not the most likely place for you to get a quick and accurate response.
Good luck.

Can an iMac be used as a monitor from a Mac Book air

Can Imac be used as a monitor for a Macbook air?

Yes, but on the imac you have to push command + F2 to enter it into the Target Display Mode.
You only can connect an iMac via thunderbolt to MacBook Air only possible when both have a thnderbolt ports
or iMac via MiniDisplayPort to MacBook Air only possible when both have MiniDisplay ports.

How do I get messages to go back to an AIM account? It's only seeing the iPad's Facetime email address and not seeing the old AIM account name that is on my desktop. I am using my iMac using iChat to talk to a newer iMac that doesn't have iChat.

I am using my iMac using iChat to talk to a newer iMac that doesn't have iChat. We had this working using Messages and Facetime (on the new machine) talking to my existing iChat account. One day last week, when Facetime rang, my kids answered on the iPad. Dang! Now it's all fouled up! The new iMac won't see my AIM account name and shows that I'm offline, because the iPad is off. We were able to call using "most recent call" in Facetime, but now I can't go and control that new iMac remotely to help with some email concerns the user is having. I'm trying to not personalize this too much, but it's grandkids talking to Grandma and Mom and Dad trying to solve new machine hiccups. Normally, I could just go in via iChat and control the other machine and troubleshoot, but I can't do it with Facetime only. My buddy list doesn't see the other computer even though we are connected on Facetime right now. My name is not highlighted for the other computer. What could have gone so wrong?
Any help would be appreciated.

If that configuration supports Target Display mode, use it. If not, use a product such as ScreenRecycler.

Strange issue with external monitor, only working when external speakers plugged in (using Thunderbolt to VGA adaptor)

Hey – I am having a very strange issue with my external monitor; where it only works if my external speakers are plugged in and connected.
I am using a late 2011 Macbook pro, running Mavericks 10.9.4, along with an MBox 2 (USB Audio Interface), and two powered speakers (KRK Rokit 5). This setup has had no issues. I have just acquired an external monitor (Benq T2200HD), which I am using with a thunderbolt to VGA adaptor (a cheap Chinese knockoff adaptor).
To start - I plugged the monitor in with the thunderbolt adaptor, and it powers up and works fine. However, there is a nasty buzz coming from the speakers. I did some research and it looks like a simple ground loop issue. I did a bit of troubleshooting, and this is where things get weird.
What I found is - If I unplug the MBox, the monitor loses signal from the computer (displaying ‘No Signal Detected!’). Further, if I keep the MBox plugged in, however unplug both the cables from the MBox to the speakers, the monitor loses signal. It doesn’t matter if the speakers are turned off, however they need to be plugged in (or the monitor loses signal). Weirder still, I can unplug the MBox, however the monitor will work if I plug in the speakers through my macs headphone jack.
Simply put, the monitor only works if there is a direct connection between the computer, the speakers, and the power source. What is going on here? Is the monitor grounding through the computer port, to the speakers (I don’t know how this works, is this possible?). Could it somehow be the cheap VGA adaptor I am using?
Some other information:
- Everything is plugged into the same multi-box for power. I have tried plugging things into separate sources, and the result is the same.
- If I unplug the thunderbolt adaptor, then the speaker noise disappears straight away.
- The ground noise doesn’t appear in my headphones, which are plugged into the MBox.
Any information would be great – am I missing something here, or is this genuinely weird?

Well, I went back into Best Buy to test on 3 other laptops (2 Asus, and their floor model for this Sony). It seems to be doing the same problem so at least I was able to rule out broken hardware issue on my particular laptop.
Here's what I did to test:
Since I couldn't really install Adobe Premiere on their machines, I used the DVIO software (http://www.carr-engineering.com/dvio.htm) and a 5 min clip I captured. I transferred onto their machines, hooked up my Sony D8, and attempted to play the video. It would play for 15 seconds and then stop and jitter with a loud noise (like it does on my laptop). I even tried changing each machine's firewire driver to the legacy one and same results. I pulled a brand new 4 pin to 4 pin firewire cable off their shelf and still the same problem.
I think I've nailed it down to Win7x64 bit Home Edition not playing nice with Firewire driver. Very annoying. I can't find any concrete evidence of this from other users on any of the forums that have my particular problem, but from my own testing, it's all I can conclude.
I have 2 other things I can try:
1. Opening the laptop and looking at the firewire to maybe find appropriate driver (ugh, I don't want to have to open this thing up).
2. Upgrading to Win7x64bit Pro and possibly testing with XP on the new MS Virtual PC (http://www.microsoft.com/windows/virtual-pc/). I can't do it with my Home edition apparantly.
Who needs to view video on an external TV anyways....sheeesh...(scarcasm).

I'm trying to set up a dual monitor for my new iMac. I'm using a second display I used with my old G5. My iMac recognizes the second monitor but the monitor won't turn on. Power button doesn't do anything on the monitor itself.

I'm trying to set up a dual monitor for my new iMac. I'm using a second display I used with my old G5. My iMac recognizes the second monitor but the monitor won't turn on. Power button doesn't do anything on the monitor itself.

If it won't turn on then the monitor is dead (power supply?, video circuits?). Not worth repairing.
If you have a new iMac then it has thunderbolt. So exactly what is that monitor you are trying to connect? For TB you can connect a mini-displayport monitor. Probably (not 100% sure with TB) can use dvi or vga too if you have the appropriate adapter.

Only use the extern monitor??

Hee,
i have my macbook (black) connected to my HD tv with HDMI. Is it possible to use only the tv screen? so that the screen of my macbook goes to sleep?
thnx (H)

The only way to use the external display only is to use your MacBook with the lid closed (aka Closed ClamShell). Any other way (Mirrored or Extended) and you would be using both displays however you may turn down the brightness to lowest on your MacBook if you wish.
Does this answer your question?
Here's how to do Closed ClamShell: http://support.apple.com/kb/HT3131

Is there any way to use a late 2009 21.5 inch iMac as an external screen for an early 2011 MacBook Pro?

Hi there,
I'm trying to work out if there is any way that I can use my late 2009 21.5 inch iMac (running OS X 10.6.8; mindisplay port) as an external or second monitor when connected to my early 2011 13" MacBook Pro (OS X 10.6.8; thunderbolt).
From what I've read online, I gather that I cannot simply connect the two with a minidisplay port to thunderbolt cable, as the iMac does not support target display mode. I know I can 'share screens', but this doesn't give me much of an improvement on size compared to just using my MacBook.
Are there any other potential work arounds I might have missed? Any suggestions (or even conclusive answers to suggest I'm wasting my time by continuing to think about it!) would be much appreciated.
Many thanks!

Sorry but no, you are asking about Target Display Mode and the 2009/2010 21.5" iMacs did not support that, only the 27" iMacs did. You can read up on TDM in Apple's Target Display Mode: Frequently Asked Questions (FAQ)

Cheap monitor for my older imac

Just looking for a cheap monitor to use as a display for my older imac (g5 ppc) which has recently gone dark. I believe the display went bad but it's possibly a graphics card issue. Just would like to find a cheap temporary solution to be able to load up my iPads and iPhones with music and movies and basic computer functions until I can afford a new Imac or possibly MacBook. Is there anything that I need to know about compatibility issues or is it just as simple as hooking it up via the USB ports on the back of the Imac?

I connect my MacBook Pro at work to various different external monitors, and my daughter uses a Samsung external monitor sometimes with her MacBook Air. With our laptops, the default has been that the external monitor shows up "mirrored," which is what you want, since that means the external monitor shows the same thing that is on the built in monitor. Not so good would be to come up in the extended desktop mode since that might not give you access to various menus, the dock etc. on the external display (those things would be on the built in monitor, which isn't working for you.
I can't promise you which it will be for you, but my experience has been that mirrored is the default (which is what you need), and to get extended desktop you need to go into the Displays Preference Pane and explicitly set that up.
If you really are going to try an external monitor, I'd get one at Best Buy or Amazon or somewhere like that who offers a no questions asked return policy in the first 14 or 30 days. So if you are stuck with your Mac in a mode that doesn't allow you to use the external monitor, you can return your purchase.
I also have a G5 iMac, and frankly, if the monitor went out, I'd simply replace the computer. The other parts inside are probably wearing out also. The February 2013 issue of Macworld discusses the latest Mac Mini's, which cost only $599 or $799 and are extremely fast and capable machines. These are Apple's "low end," and they are really superb machines. And if you get an external monitor, you can use it also with the Mini. By the way, if you buy an external monitor, I recommend staying away from the cheap loss leader units that are often advertised and instead spend a little more to get a quality Samsung or other good brand name monitor, possibly an LED one. The quality of the screen and images and resolution do make a big difference in the use experience. I got my daughter a low-cost ACER monitor first, and she is a photographer and demands high quality images on her screen, eventually we traded it back in at Best Buy (Best Buy has a nice trade in policy where you get a credit) and replaced it with a high quality (costlier) Samsung LED monitor.
The G5 iMac is so limited, both in its hardware and software, that I'd say if you can afford it, look at the latest Mac Mini or iMacs. Even the low-end ones are probably x10-x20 times faster and more capable than the iMac G5 and you can do all the latest things with them.

Re-install utility, activity monitor only

can someone help me to reinstall activity monitor as the original support and or library files are corrupted or missing (7yr old "assistant" at work)
I do NOT want to reinstall the whole osx, only activity monitor.
thanks very much.

bluezedd,
The Console Log message begs the question, and I know you previously repaired permissions, but have you tried to permissions repair one more time after you reapplied the Combo Update?
The setuid root message seems to point to ownership issues, but I am not the one to speculate or make recommendations at that level of the system.
The "7yr old "assistant" at work" appears to have done more damage than would be expected with a simple removal of Activity Monitor.
I know that you said that you did NOT want to reinstall the the whole OS, but considering the time that you have already spent on this problem, I would suggest that an Archive and Install of Panther followed by the application of the Mac OS X Combined Update 10.3.9, would be the best course of action.
I have successfully used Archive and Install on my G3 iMac when I replaced the Hard Drive, and I was impressed by the fact that all user settings and preferences remained intact.
Whatever you decide, make sure you are properly backed up.
Good Luck.
;~)
