24 inch iMac with a second monitor (1920x1080)

I just purchased an HP w2338h and have it hooked up to my 24 inch iMac as a second display. I am using a VGA cable with the apple adapter. The problem is, it won't support the native resolution (1920x1080). Every resolution below this works fine but I obviously don't want to use a lower resolution. I have the option to choose 1920x1080 but when I do, it leaves a two inch black gap on the left side of the screen and puts strange bands down the part that does show up. Any help would be appreciated. Thanks.

Seems to be the right adapter and cable for you as well.

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.

Can I use my 24" iMac as a second monitor for my Mac Pro?

I bought a Mac Pro with the 27" Cinema display and it's great. Now I want to use my old 24" iMac as a second monitor.
How can I make this work?
I appreciate all you support!
Thanks

By using ScreenRecycler and a network connection.

I want to use my old iMac G3 as second monitor to my MacBook Pro, how?

Thanks!

You can't really do it in any normal way; that is, using the MacBook's video output port.
You can use this program
http://www.screenrecycler.com/home.html
to make your iMac screen act as a second display, over a network connection. ScreenRecycler runs on your MacBook and creates a virtual second display. It uses the open-source VNC (screen sharing) protocol to serve that second display over the local network. You then run a VNC client program (usually free) on the iMac G3 and display the MacBooks virtual second screen in a window, which you can display full screen. Your iMac then appears to be the MacBook's second screen. You use System Preferences Displays pane to set it up, as you would a real second display.
How well this works depends on your iMac's speed, what Mac OS version it runs, and the speed of the network connection. If you connect the two directly with an Ethernet cable (Cat-5 or better), the network speed should be decently fast (at 100Base-T). If your iMac G3 has Tiger (10.4), you can use this program as the VNC client
http://www.jinx.de/JollysFastVNC.html
(there are free VNC clients for 10.3 and earlier)
However, this solution will never be as fast (in terms of screen refresh rate) as a real display using a real video connection. But you can try it at no cost, to see if it meets your needs.

Mid 2011 21.5 inch iMac with lion video=freeze, will not restart for 30-60 minutes , today it took 14 hours before power button would restart it , is anyone else having a long restart after this problem?

Look in Activity Monitor (Applications - Utilities - Activity Monitor) and see if you have any runaway processes using a lot of %CPU.
I would also strongly recommend running Apple Hardware Test in Extended Mode. If it reports errors you can Google them or post them here.

10.7.5 is not the latest system, 10.8.3 is. However your message sounds like a Kernel Panic, does the message look similar to About "You need to restart your computer" (kernel panic) messages? If so, then if you can get the machine to restart normally then please post the Kernel Panic Report which you can find by following directions in How to log a kernel panic. Please post back with the KP log, and we can take a look. However if the machine continues to not restart then my guess is a hardware failure suck as a hard disk or failed RAM in which case you should take it into your local Apple Store or AASP for repair.

I have a 27 inch iMac with maverick os. my current version of iMovie (10.0.6) will not open older projects i created in iMovie 9.0.9. I can find the projects and they have a ".rcproject" file extension

Thank you GeeD. I'm still stymied.
I have moved the Event and Project Folders to the "top-layer of the drive" as the instructions state, right alongside the System Folder, Users Folder and Applications Folders.
When I open iMovie 10.0.8, the Events and Projects Folders are empty:
When I select File/Update Projects and Events, I get an alert box that says iMovie couldn't find any:
Not knowing exactly what is meant by the "top layer" in the instructions, I moved the Events and Project folders back inside the "Movies" folder where I found them (but then not where I would call the "top" layer, but rather "iMac/Users/Home/Movies/iMovieProjects". Then I tried to "Update Projects and Events" and received the same alert: "iMovie could not find any projects or events to update."
Then I tried to update iMovie 9.0 (iMovie '11 version 9.0 (1073)) to version 9.0.9 .
[As an aside, the nomenclature of iMovie drives me nuts. The latest version is 10.0.8, which us newer than iMovie '11.]
Back to the update of version 9.0 to 9.0.9.
Presumably because I have version 10.0.8 installed, I got this alert box:
So, I cannot update version 9.0
and I cannot "Update" the Events and Projects created in version 9.0.

I have a macbookpro with a second monitor connected using an Apple connector. The two screens show different parts of the desktop. My cat walked across the keyboard, and now the two monitors are showing the same thing. How do I undo what the cat did?

Have you tried HELP in FINDER? If you open HELP and enter 'displays' in the field in the upper right hand corner you will get a list of topics on setting up monitors. Specifically read 'Setting up multiple displays to show the same image' and 'Setting up multiple displays as an extended desktop'.
Ciao.

What firewire will connect 27 inch IMac with Cannon GL2 digital camcorder

What firewire will connect 27 inch IMac with Cannon GL2 digital camcorder?

According to the Canon spec's a > 4 to 9 pin firewire cables is what you will need, provided that you have a slightly older 27" iMac that still has a FireWire 800 port.

Graphics problems with my second monitor...

Ever since I updated to Lion, I get some display problems with my second monitor (a Samsung LED XL2370).
Single windows appear darker and with bad graphics, especially when dragging from the normal monitor to the external one or openign them..
And after 'waking' my MacBook from sleep today, the background image of the normal display was missing. It was just a grey screen, but perfectly functional. And nothing changed when I checked the display settings and tried changing the background.
Any ideas??
A screenshot with both problems in it.. Acrobat Reader was sitting between two monitors, the right display is the external one

After 10.7.3 i was optimistic apple finally fixed the bug....but it seems that they were not successfull or just didn't care....
I'm seriusly really sour about the rapidly decreasing quality apple delivers.....thinking more and more about switching back to linux again....

How to use an iMac as a second monitor for an iMac

I have two 21.5 inch iMac's (late 2009) and I want to use one as a second monitor for the other. I have a Mini DisplayPort to Mini DisplayPort connector but when I connect it to both computers, nothing happens. I'm not sure if I'm doing something wrong once they're plugged in or if I have the wrong cable all together. Any tips or advice would be much appreciated. Thanks

Not going to work, the ONLY 2009 / 2010 iMacs that supported Target Display Mode were the 27" models, 21.5" models simply will not work. Please read Apple FAQ on TDM and you will see I am correct.
Target Display Mode: Frequently Asked Questions (FAQ)
While Neil is correct, Screen Recycler's performance is not that good so the user experience probably will not be worth it.

Using an imac G3 as second monitor for intel imac

I just purchased a 20 inch intel imac and was curious if I could use my old imac G3 as the second monitor.
I already have the DVI to VGA adapter to use in the mini DVI port on the intel imac. Is there an adapter that I can use to plug this cable into the VGA out on the back of my old G3 imac?
intel duo imac Mac OS X (10.4.6)

The VGA port on your old iMac is output, not input,
so what you are suggesting wouldn't work.
To do it, you'd have to take apart the G3 and hack a
connection from the gfx card to the display to
work... probably more trouble than it's worth, given
the quality & res of the old g3 displays.
Thanks for the quick response. Looks like I will have to pick up a second monitor.

IMac with 2 HDMI monitors?

My iMac mid 2011 (27 inch) refuses to work with 2 HDMI monitors using thunderbolt to HDMI adapters.
I tested the adapters, they work fine (on their own).
If I replace one of the cables with a VGA adapter both monitors work.
So, how do I get it to work the way I want without resorting to this workaround?

Not sure, see below.
You could hook one monitor up using a mini-diplayport to HDMI adapter.
Mini DisplayPort | Thunderbolt® to HDMI® Adapter w/ Audio Support
Hook the other via USB.
USB 2.0 to HDMI® Display Adapter w/ Audio (1920 x 1080)
USB 2.0 to HDMI Audio Video 1080P Adapter for Windows and Macbook
Newer Technology USB to DVI / HDMI / VGA HD Video Display Adapter
And lastly there's this:
Matrox DualHead2Go
After looking at the descripton of that Apogee MDPHD2X I am not sure whther it distributes one video input to two HDMI's producing a mirrored display or fakes the EDID information like the Matrox to make your computer think it is one lage extended display. More research is needed to verify that.
