Imac and external projector resolution problem!!!!!

hello! I´ve benn using an imac24" for about 4 months. When I attached my projector with a capasity for 1024x768 85Hz while my imac´s is 1920x1200.
My problem is that I want my imac to use it´s highest resolution at 1920x1200 while my projector is using 1024x768. Is that posible, and if, how would I make it happen?

You can only do this if you have the system set for "extended desktop", where the images on the two screens will be different. If you want to run the system in "mirroring" mode, where the iMac's screen is duplicated on the projector, then the resolutions have to match, so you'll have to reduce the iMac's screen to 1024x768 to match the maximum resolution of your projector.

My wireless keyboard no longer connects with my iMac since changing the batteries. It now shows as not connected, not paired and not configured. A friend recently connected his iPad to the iMac and since then the problem started. Any ideas to resolve this

a friend told me that he wants my os x cd for my macbook pro to upgrade his imac.
The discs that come with your Mac are "machine specfic" and cannot be used on another Mac.

I downloaded OS X Lion on my iMac and I'm having problems with my computer waking up after hibernating. I can get to the login screen but my mouse will be frozen. The only fix's is a hard reboot. Any help would be great!

Try resetting the SMC and the PRAM.
1. SMC
Read this and follow the instructions for your kind of mac:
http://support.apple.com/kb/HT3964
2. PRAM
Follow the procedure below:
1. Power down the machine.
2. Locate the following keys on your keyboard in preparation for Step 4:
command–option–P–R
3. Press the ‘power on’ button.
4. Immediately – and before the grey screen appears – hold down ‘command-option-P-R’ all together.
5. Keep them held down until you’ve heard the start-up chime twice. After you release them you should hear it again, and hopefully your Mac will boot up as it should normally.

Read the router's user manual on how to change your password.

20" iMac and external Dell 24" : doesn't work with Mini DVI to DV adapter!

Help! My lovely Dell HP LP2475w 24" Monitor can't be used as an external monitor. The native screen resolution is 1900x1200 60Hz. The Apple site claims the iMac is capable of being able to output this resolution.
When the HP is plugged in via the apple mini to dvi adapter a (tested) DVI lead, it recognises the monitor, but can't bring it to life. Just an occasional flash. In the resolution listing for the HP, the native resolution 1900x1200 isn't listed.
Plugging a cruddy old 20" Samsung with the same DVI leads works with no problems.
I NEED to use the HP for my Photo editing, and phone calls to Apples support have proved fruitless.
Does anyone have a 20" Intel iMac and an HP LP2475w set up that works?
Many thanks for any help.

I'm glad you got it working!
So do you have it working at full 1900x1200? I've noticed a few more oddities about my iMac on this monitor. First off is that initially I could only go as high as 1680x1050, which I think is the native resolution of the iMac. Now I actually see two more options, one of which being 1920x1200. This surprises me since you couldn't get it to a full 1920. Both resolutions produce the same size image on the HP, but the 1680x1050 is fuzzier. It's odd to me, same dimensions just a little less clear. I can stretch that using the HP's settings to full screen, but I cannot adjust the 1920/1200 image even though there is a black border around it.
Can you tell me what color settings you have on the HP? I have really struggled to find something I like. I actually like how things look in my iMac, and my MBP. I can't get things to look the same on the HP. I also feel like text is just a hair fuzzier on the HP than on either the iMac or MBP. I'm tempted to try a used 23" Apple Cinema Display, but I'm not sure I'll have any better luck with that. I mostly concerned about the image quality when I use my laptop, and for some reason I'm not getting great results with the HP or Dell externals that I've tried.

Transferring files from original imac AND external CD for old imac

I have an original iMac that has tons of files on it I would like to save. I created a LOT of materials when I was teaching and they are all on the old iMac. It also has two games I bought on floppy discs that I would really like to keep. I tried to load files on a Passport, but the iMac won't recognize it. I have two other old iMacs (not quite originals) as well, but they won't take the Passport either. They will both take a flash drive. I can take word processing files (I can't even remember the application at the moment) off the older one and convert them to Apple Works on the other one, then take the converted files to our iMac 9.1 and convert them to Pages. Then I put them on the Passport. It is a pain, but at least it works. I can also save the documents as pdfs and put them directly on the newer iMac and copy and paste in a Pages document.
The original iMac does not lend itself to any of this. What is the best way to transfer files? It seems like a very long time ago I tried to connect it to my newer iMac with an Ethernet cable but it wouldn't accept the cable. If I am remembering correctly I called Apple Support and they said it lacked something that would allow it to connect. I do not remember if I have tried a flash drive on it or not. I believe I did and it would not recognize it.
Also, does anyone know how I can manage to save a copy of the games? Since I bought them on floppies I can't reinstall them if something happens, but I believe it is within the law to make a backup copy. Someone please correct me if I am wrong. I do have an external floppy reader for the original iMac, but it only works on user created floppies, not commercial ones. If I can manage to hook up to a flash drive or another computer and I simply save the game application, will that be enough? Or is it not possible to know until I try? Will saving the application get all the necessary files?
My second question concerns the newer (but still really old) iMacs. My daughter would love to play some of the games she used to play on them, but the CD drives do not work. Does anyone know where I can get an external CD drive that we can attach to these old iMacs so she can enjoy her games? The computers work fine; she just can't insert the CDs, because it's next to impossible to get them out again.
I believe on the "newer" two we are running OS 9, at least on one of them. I do not recall the OS on the original, but it is whatever it came with. OS 8, perhaps? It has been probably half a year since we fired it up.
I appreciate any advice and help anyone can give me. We really like these old iMacs, which is why we still have three of them. If we can save the files off the original iMac, we would still keep it so we could play our two old games from time to time. :-) I would part with one of the other old iMacs, but I really need to get the files first, and since it won't take a Passport I'm wondering if I'm stuck putting files a few at a time on a flash drive. Do you think it would take an ethernet cable? It seems like I tried to connect to my newer iMac but I couldn't get the computers to recognize each other. I followed all the steps for sharing, but I still couldn't get it to work.
Thank you so much.

Have you formatted the Western Digital Passport drive as a Mac OS Extended (HFS+) volume, or is it factory-formatted for PCs? If the oldest iMac is only running OS 8, it can't recognize HFS+ volumes. It was OS 8.1 that introduced that feature. Additionally, the version of the USB support files (which is somewhat OS-dependent) on the iMacs hard drives affects what will or will not be recognized by those older computers. With each successive release of the USB Adapter Support, the database of supported devices was broadened. The easiest way to transfer the contents of the iMac's hard drive is to physically remove it from the computer and connect a USB-to-IDE adapter directly to it. These adapters come with an external power supply to provide the 12 & 5 volts needed to power the drive. The data connection block is designed to fit either a 3.5" hard drive or the smaller 2.5" laptop drive, as well as newer drives that connect via SATA. It has an included USB cable that connects to a standard USB port, enabling direct reading/writing/file transfers from the hard drive to the computer to which it's connected. These adapters are not Mac-specific in terms of design, so you can buy one at a PC store and use it. For the purpose of identifying such an adapter, here's one that's often recommended in these Forums, carried by Other World Computing. As I mentioned, this adapter is not platform-specific, so you can buy/use a less expensive one sold by PCs stores. I bought one for $15 from Micro Center (PC store), and it has worked with Macs and PCs. As for removing the hard drive from the old iMac - and I assume that it's one of the original models with a tray-loading optical drive (as opposed to the slightly newer ones that have a slot-loading optical drive), you can find directions for accomplishing that if you do a web search. The link that I had for one site (that was good for years) is no longer valid. The iMacs that have a problem ejecting disks are undoubtedly slot-loading models. There are two wide rubber rollers inside those optical drives that grip the disk to pull it in or feed it out. Over time, the rubber dries out, causing the rollers to lose their natural gripping capabilities. If those iMacs have a FireWire port on the side, I'd suggest an external FireWire optical drive. Today, the only type you'll find is a DVD±RW drive, which is more than you need for your intended purpose. A basic CD-ROM drive isn't manufactured/sold anymore. Other World Computing has a few FireWire optical drives, but their least expensive model sells for about $100. Obviously, that costs more than the value of the entire iMac at this point, but the drive will also have USB connectivity as well. You may find other uses for it with your other computers (Macs & PCs), especially if they don't have a CD-R, CD-RW, DVD-ROM, or DVD±RW drive. As for transferring a program itself, there could be other associated files. You'd want to check the Extensions and Control Panels folders for any that are named to likely indicate being a part of the program's installed files. The Preferences folder will probably have a file that has saved game settings, but a new one would be created when you run the program in another supported computer. Depending on the age of the program - and you indicated that it was on floppy disks - its compatibility with newer, pre-OS X releases might be limited. The external USB floppy drive that you use with the older iMac should read commercial floppy disks, but it will not recognize the older 800K (Double-Density) Mac-formatted floppy disks. They're disks that typically format as 720K floppies in a PC, but the variable-speed FDD in older Power Macs was able to fit an extra 80K of data onto those disks. A standard 720K "PC" floppy disk should be read by that drive, but it can't recognize an 800K "Mac" disk. A 720K/800K Double-Density floppy disk only has the slide-lock hole at one corner, while a High-Density (1.44 MB) floppy disk has an additional hole at the opposite corner to differentiate it from the older type.

Airplay screen mirroring on 4:3 projector, resolution problems.

Hi!
I have an iPad 3, an ATV3 and a NEC NP400 projector which I'm trying to get to work together. I'm not sure about the projectors resolution, but i know it has a 4:3 aspect ratio.
I've tried to use screen mirroring with both the ATV 3 and a VGA adapter, and the problem is that I get black bars on each side no matter which method I use. I understand that the iPad 3 has a 4:3 aspect ratio and that black bars would appear with a 16:9 screen, but not on a 4:3 screen which is the ipads native aspect ratio.
It feels as if the iPad by defalut assumes that I'm having a 16:9 projector and adjust the aspect ratio to that fact. Is there anyway to tell the iPad that i'm having a 4:3 projector? Or should it detect that automatically?
The ATV fills the whole screen without black bars on each side, but as soon as I'm turning screen mirroring on via airplay the aspect ratio changes. There is no difference if I'm using the ATV or the VGA adapter.
How does these things work, and is there a solution?`
Thanks!

Acer AL2032w as an external monitor: Resolution problem

Hi,
naive as I am I bought the AL2032w widescreen LCD for my new PB and didn't expect any problems since the monitor has exactly the same max. resolution (1680x1050) as the PB LCD itself and as the Apple 20" Cinema Display... well...
Now the monitor settings of OSX identify the display as "Acer MFM DVI" and only offer me strange resolutions like 1600x1200, 1360x768, 1344x1008, etc.
What can I do to get the full 1680x1050?
Thanks,
Y.
PS: "Buy a cinema display!" is not an answer...

I am not positive of this but it sounds like you may
have to make a trip to the Monitor Manufactures Web
site and see if they Offer an update to the Firmware
Drivers for this Monitor for your Mac and Operating
System.
It might also be that the settings that you have
found that are available to your Mac might be all you
have, and the Higher resolution and drivers and
firmware are for a PC.
Cheers Don
Well the problem is that the Firmware should be up to date (monitors are brandnew), and drivers are an issue of the graphic card provider, and here ATI refuses any help since it would be Apple's business to do this...
So, I'm still open for suggestions, especially how to tinker with the monitor settings in Tiger, I'd expect the monitor to work if I could make the Mac believe it is an Apple Cinema Display...
All the best

IMac And Firewire Solo - Power Problem

Hi!
I got an iMac and a M-audio Firewire Solo audio interface. I wanted this interface to be powered by the current adaptor and NOT by the iMac.
M-audio says that if I plug it with a 6pin cable the computer will power the interface (not using the adaptor). So Can I avoid iMac to power the interface? I mean by stopping the firewire power or something..
thanks!!!

The easiest way would probably be to put a pair of 6 pin to 4 pin adaptors (of opposite "genders") into the cable run, or to use a 6 pin to 4 pin cable with a single 4 to 6 pin adaptor on the end of it, vivajam. THis should cut the power supply from the Mac to the device.
http://www.granitedigital.com/catalog/pg20_firewiregenderadapters.htm seem to have the sort of thying you would need.

Imac and external hard drive

I'm not sure I'm posting in the right category but here goes anyway. I am hoping someone who has had a similar problem can give me advice.
I bought a Western Digital "My Book" 250 gig external for my imac back in July. It has fail and I am getting nowhere with WD support. It's still early but I have a bad feeling about them. The only communication is through email which I find a bit short of full support.
All of my music and photos are in that drive along with other important data. I'm prepared to write the cost of the drive off as a loss but is there any way to recover the data from the failed drive.
I did backup most of the purchased music and some of the photos but many are not backed up.
Thanks in advance for any help you can give me,
Don

You might be able to dismantle the My Book, remove the drive, put the drive in an external FireWire or USB enclosure and copy the files to your iMac. This will work IF the My Book enclosure has failed but not the drive.
If the drive has failed (probably the case) the data would only be recoverable by a data recovery service. Usually these services are expensive.

External monitor resolution problems with Mountain Lion

I have a problem with my external monitor (Samsung LS19B150NS) and Mountain Lion (running on unibody Mac Mini). Each time I reboot OSX the resolution get reset from native 1366 x 768 to something lower. The display is connected via DisplayPort-to-VGA adapter. Some observations:
- I tried selecting "Best for..." option or "Scaled" (set on 1366 x 768 or 1360 x 768). The problem is still there
- Sometimes resoltuion might stay alright for several reboots, but then the problem re-appears again
- Sleep mode doesn't reset resolution
- Other monitors work fine via the same adapter
- The Samsung LS19B150NS work perfectly well with other Win PCs
Any suggestions how to fix it?

IMac and External Monitor

I have an early 2006 iMac 20" core duo 2.0ghz 2GB Ram.
I already have an external 17" monitor plugged in with the mini dvi adapter.
I have recently purchased a 32" Samsung TV, which has PC Input. This will be arriving shortly.
Is there any way for me to connect both the TV and the external monitor to the iMac? I would rather mirror the display to the TV and extend the desktop onto the 17" monitor.
If there is a way to output to both, but by a different way - i.e. not mirroring and displaying - this would be great.
I didn't know whether it was possible for me to use some sort of splitter. So a mini dvi to 2 vga's. Then vga to tv and monitor.
Thanks for the help.

Macbook Pro 13 inch & External Display - resolution problem

Hi
I'm trying to connect my macbook pro 13inch to an NEC 26' Multisync display - which has a native resolution of 1900 x 1200 - and when connected to a PC this is what I get. When I connect the mac though the top resolution is 1900 x 1080 - so the display is distorted.
I've tried finding diplay drivers for the monitor and graphics card without success. Apparently the GEForce 9400 graphics in the macbook can output up to 2500 x 1600.
I'm wondering if it's the connection method - I'm using the mini display to VGA adapter that I got with the macbook. Do I need to use the alternative adapter - the mini display port to DVI adapter? Seems this is needed for connection to 'advanced' displays. Will this make any difference or is it that the macbook 13 inch can't output to a 26in display?
Any advice or assistance will be greatly appreciated
Many Thanks
Tim Gundry

I would get the DVI regardless.
Your taking a digital signal from the macbook, converting to to anolage VGA, and the the monitor is converting it back to digital again to display on the screen.
DVI will make it direct digital to digital.
Plus, because DVI is digital, is passes resolution information. So you should get your native resolution no problem.

External monitor resolution problem

Imac and external webcam

Hi all,
I have a G5 with an external isight.
I'm getting a new iMac soon.
My questions is...in my business the external cam is handy in that I can move it
anywhere. If I need to show a client a tool I'm working on I can do so.
With an iMac I have to move the whole computer around.
Soo for those times I need the flexibility of an external....
1. Is it possible?
2. How would I go about doing it if it is
3. Since this external iSight is starting to work when it wants to...
whats a good 3rd party web cam to use? I know there are none close to an iSight but...
Thanks in advance

Plenty of folks report using the FireWire external iSights with no real issues. Some have had issues with the microphone, but there is a fix for that, I think in the Mac mini Apple Discussions.
I have also seen folks recommend this one; http://ecamm.com/mac/imagewebcam/
Sometimes with USB webcams on iMacs with built in iSight cams, you have to fool the Mac to use the external cam. The Mac defaults to the internal, so you have to occupy the internal with another app, then open the app you want to use and the external should be available to choose. After choosing you shut down the other app.
